Click on the Erase button. The format process can take up to several hours depending upon the drive size. Dec 23, 2011 Mac OS X automatically sets permissions to limit a user’s access to system files and other user directories. If that protection isn’t good enough, you can change permissions to prevent other users from doing stuff like editing your 'Great American Novel,' reading private financial documents, or opening a specific application.
Summary: Two methods to change Seagate external hard drives from read-only back to read-write, so that you can edit, delete, and rename files on this Seagate external hard drive. Also, if a Seagate external hard drive is read-only or files are locked on Mac due to NTFS format, you can use iBoysoft NTFS for Mac to mount it in read-write mode on Mac.
When you plug a Seagate external hard drive into your Mac, one of the worst things would be that you find your Seagate hard drive is read-only. Your photos, videos, and other files you saved from a Windows PC could be locked. Or your Seagate external drive could be write-protected. Are you facing such disk problem right now? Well, you are not the only one.
'I'm having a problem using my Seagate external hard drive. I only have permission to read files on my external hard drive, but I am not allowed to write or edit files on the drive when using Mac OS. Why this happened and how to fix Seagate external hard drive read-only on Mac?'
You might have trouble backing up or adding files to Seagate external hard drives on Mac. But it's not necessarily because the disk is locked but some other reasons. For example, the Seagate external hard drive becomes read-only on Mac.
In this article, we introduced three possible reasons for disk being read-only on Mac, and you can find solutions to change the external drives from read-only accordingly.

- Why a Seagate external hard drive is read-only on Mac?
- Case 1: The Seagate external hard drive is NTFS formatted
- Case 2: You don't have permissions to access the Seagate external hard drive
- Case 3: The Seagate external hard drive has some disk errors
Why is your Seagate external hard drive read only on Mac?
You may be wondering why my Seagate external hard drive is read-only. In fact, read-only Seagate external hard drive results from various reasons. It could be the NTFS format that makes this trouble since NTFS is not writable on Mac. Generally, there are three possible reasons:
- The Seagate external hard drive is NTFS formatted
- You don't have permissions to access the Seagate external hard drive
- The Seagate external hard drive has some disk errors
In the following part, we'll go into details about how to fix the Seagate external hard drive read-onli issue in different situations.
Case 1: The Seagate external hard drive is NTFS formatted
Most Seagate external drives are read-only on Mac because they are pre-fomatted with Windows NT file system (NTFS) by the manufacturer. So your Seagate HDD is read only on Mac, which affects Seagate Backup Plus Ultra Touch, Portable drive, and Slim.
However, macOS disabled the NTFS write support by default. If you connect an NTFS formatted external hard drive to your Mac, you will find that files on this disk will be locked or show as read-only. You can only read but can't add files to this Seagate external hard drive on Mac.
How to check if your Seagate hard drive is NTFS formatted on Mac?
- Open the Finder and click Go at the upper right of your desktop, then choose Utilities.
- Find Disk Utility and open it.
- Select your Seagate external hard drive in the left sidebar of Disk Utility.
- Then you can see Windows NT File System on the right.
- You can click the Info icon at the upper right to check if this disk is writable.
Solution: Use NTFS for Mac to write to Seagate external hard drives on Mac
In this situation, what you need is not to unlock the Seagate external hard drive but a NTFS for Mac driver. Many people would think about converting NTFS to APFS or formatting the Seagate drive for Mac to make it compatible with macOS. However, the truth is that you can fix the Seagate external hard drive read-only issue without formatting, i.e. you don't have to lose your files on this drive.
Alternatively, you can download NTFS for Mac software to enable NTFS drive write support on Mac with no fuss. There are a great number of NTFS for Mac in the market, and iBoysoft NTFS for Mac is used here as an example.
iBoysoft NTFS for Mac: NTFS for Mac driver and more
iBoysoft NTFS for Mac is a handy disk management tool, which can help you mount NTFS formatted external hard drives, USB flash drives, SD cards, etc. on Mac with write support. This NTFS drive mounter is also compatible with macOS 10.15 (Catalina), macOS 10.14 (Mojave), macOS 10.13 (High Sierra), macOS 10.12 (Sierra) and Mac OS X 10.11 (El Capitan), 10.10 (Yosemite), 10.9 (Mavericks), 10.8 (Mountain Lion).
How to use iBoysoft NTFS for Mac to write to NTFS Seagate external hard drive on Mac?
Step 1: Download and install iBoysoft NTFS for Mac on your computer.
Step 2: Launch this NTFS driver for Mac and connect the read-only Seagate external hard drive to Mac.

Aside from being an NTFS for Mac driver, iBoysoft NTFS for Mac is also a wonderful tool to manage files on NTFS external drives. It lets users open, monut, repair, and erase NTFS drives on Mac natively and seamlessly.
Case 2: You don't have permissions to access the Seagate external hard drive
If your Seagate hard drive denies your access or restricts you to read-only activities, there is likely an permission issue. Being a multiuser operating system, macOS sets up access permissions for all files and folders on the system, including external drives.
Solution: Change permissions on Seagate external hard drive
To fix the read-only Seagate external hard drive issue, you need to regain full access. You can ignore the ownership or change the sharing and permissions of this disk in the Finder by following the below steps.
Step 1: Select Seagate external hard drive on your desktop or in the Finder sidebar, and then press Command + I to get information of the drive.
Step 2: Scroll to the bottom of this list and click on the triangle that is at the left side of the Sharing & Permissions tab.
Step 3: Click on the lock icon at the right bottom and type in the password to unlock this tab.
Step 4: Check the box to Ignore ownership on this volume, or you can toggle it off and then on if it's already enabled.
Step 5: Click on the gear button and choose Apply to enclosed items… to save your changes.
Then you can go to check if your Seagate external hard drive is read-only still. If not, you will be able to write to this disk.
But if you can't access the Seagate external hard drive as it's locked still. Well, the disk may be really locked by certain programs, especially for Seagate Backup Plus Ultra Touch. Then you need to unlock the password protection or hardware encryption with Seagate Secure software.
Case 3: The Seagate external hard drive has some disk errors
If your Seagate external hard drive becomes read-only not for the reasons above, you may need to have a check if there is any inner disk error. Some formatting errors will make an external hard drive read-only on Mac. If this is the cause, usually you will see a warning in Disk Utility that states it is only being mounted in read-only mode.
Solution 1: Fix read-only Seagate external hard drive in Disk Utility
Fortunately, there is a built-in tool called First Aid that can check and repair some minor disk errors. When your Seagate external hard drive becomes read-only due to logical disk problems, you can use First Aid to repair it then.
Here is the guidance to fix read-only Seagate external hard drive with Disk Utility:
- Open Disk Utility.
- Select the read-only Seagate external hard drive on the left window.
- Click First Aid in the top center and choose Run to repair this disk.
Solution 2: Reformat Seagate external hard drive
However, if Disk Utility fails to fix read-only Seagate external hard drive, the last thing you can try to remove write protection from Seagate external hard drives would be reformatting. Reformatting will assign a new file system to this disk, consequently, the Seagate external hard drive issue could be fixed.
But before you go ahead to erase this disk, you should know that reformatting will wipe the files on this hard drive. Thus, you are advised to check if you have a copy of data back in the first place , or you can recover lost data from this external hard drive with iBoysoft Mac data recovery to avoid data loss.
If you're sure that you have data backup in hand, you can proceed to reformat this read-only external hard drive with the following tutorial.
- Open Disk Utility as you did before.
- Select the read-only Seagate external hard drive in the left sidebar.
- Click the Erase button in the top center of Disk Utility.
- Fill in name, format, and scheme when the pop-up asks.
- Click Erase to confirm this operation.
A final note
Besides Seagate external hard drives, Toshiba, WD, Samsung, or other brands' external hard drives will come across the read-only problem. It is common to see people complaining WD My Passport external hard drives suddenly became read-only on Mac. You can also use these solutions to fix this problem. But if you are unable to fix it with the solutions suggested above, you can only send it to local disk repair store for help, but that will cost a lot usually.
Make your Mac invincible
Get Setapp, a toolkit with fixes for all Mac problems
After summer comes macOS. This long-standing tradition started by Apple is the most exciting moment of the year — seeing your Macs improve and gain new bells and whistles. In 2019, we’re welcoming Catalina, the 10.15 version of macOS named after Catalina island in California. Apparently, it’s hot.
The operating system boasts a whole lot of new macOS features like Sidecar, iOS apps porting, and major Photos update. To try the features right away, you can install Catalina from the Software Update tab.
However, be prepared for some troubleshooting. The acquaintance with the new macOS doesn’t always go smooth — and with macOS 10.15 deeming support for lots of software, many things will not go smooth. We’ve collected the key macOS Catalina issues you may encounter, along with the ways to fix them.
macOS 10.15 Catalina problems and their fixes
Giving up Catalina is a decision you can choose to make. But before rolling back, ensure you use every bit of advice as to how you can fix the common problems. Sometimes, a quick fix can solve your concerns.
Get macOS problem fixes on Setapp
Beta or not, you can safely install any version of the new macOS. Setapp and its 150+ apps will solve every Mac concern you have.
Problems with macOS Catalina you can solve:
macOS 10.15 Catalina won’t install
This is the classic problem that arises with every macOS release: The installation won’t start or you face the “Catalina installation stuck” problem — when it freezes and you see no progress on the install. No matter how many times you start over, you keep getting an error trying to install Catalina.”
How to fix:
- Apple recommends to reset SMC. Shut down your Mac, and hold Shift + Ctrl + Option + Power button for about 10 seconds, with your cable plugged in. Click on the power button and wait for your Mac to start up.
- Try resetting NVRAM or PRAM. Shut down your Mac, and hold Option + Command + P + R for about 20 seconds. Wait for your computer to restart.
- Reinstall from macOS recovery. Hold Option + Command + R to reinstall. Once you see the startup screen, start the installation again.
- Some users reported they were prompted to enter administrator password several times to complete the installation. So it might be something for you to try as well.
- In most cases, macOS Catalina cannot be installed on Macintosh HD, because it doesn’t have enough disk space. If you install Catalina on top of your current operating system, the computer will keep all the files and still need free space for Catalina. So the easiest fix would be to clean up your system with CleanMyMac X before upgrading. All the system junk, app leftovers, and unneeded files will go away in a minute.
- Backup your disk and run a clean install. This will wipe away your current system files, leaving space for macOS Catalina — so yes, this option is for the brave. If you use a solid backup solution, you’ll keep your data safe, though. Get Backup Pro is a nice way to do it — unlike Apple’s Time Machine, the app allows running bootable backups.
Say you’ve cleared up and backed up your disk. But your Mac still gets stuck at the installation and shows “not enough space” error, so you can’t get out of the cycle. In this case, there’s another fix you can try:
- Reinstall Mojave. No worries, this won’t delete your disk. Reboot your Mac and hold Command + R to enter the Recovery Mode. Click Reinstall macOS.
- Restore from your backup. If you have a Time Machine backup, enter the Recovery Mode again and select “Restore from Time Machine Backup.” Select the backup from the list and restore your files.
Some users also report they tried to reboot into Safe Mode and take the installation from there; the others used a newly created admin user — but most attempts have been unsuccessful.
We must agree that macOS 10.15 is one of the slowest systems in terms of installation. But if you use the hacks described above and have a little patience, you’ll be able to get to the “Catalina installed” point.
If you can’t login after upgrading to Catalina
There’s a known problem of failing to login after the installation. Unfortunately, the only way to fix it — at least for now — would be to roll back to Mojave:
- Clean up your Mac with CleanMyMac X and backup your data.
- Save passwords to ensure you don’t lose license keys and settings.
- Create a bootable installer of Mojave (after Catalina goes public, you can download Mojave here).
- Delete macOS Catalina: Apple menu > Restart > Command + R > Disk Utility > your startup disk > Erase.
One of the things Mac users are particularly excited about is the new Sidecar feature. It comes as a handy solution for those wanting to expand their workspaces. You can either mirror your Mac’s screen to iPad or use your iPad’s screen as an extension of a Mac.
If the only reason you’re here is because you want Sidecar, we have to warn you it might not work with your new macOS. Reddit is full of user reports about the feature unavailable on macOS Catalina. Most likely, this is the issue of compatibility.
How to fix:
Here are the ways to fix Sidecar problems:
- Get the new iPadOS 13. Unfortunately, macOS Catalina doesn’t work with iPadOS 12. So basically, you have to use the recent operating systems if you want to try Sidecar.
- Make sure your Mac is one of the compatible devices. Sidecar works on:
- 2019 Mac Pro
- Late 2018 Mac mini +
- Late 2018 MacBook Air +
- 2017 iMac Pro
- Mid 2016 MacBook Pro +
- Early 2016 MacBook +
- Late 2015 iMac +
- Try connecting your iPad with a cable. With Sidecar, you should be able to connect your iPad wirelessly. If this doesn’t work, the cable might solve the issue.
Battery drain on macOS Catalina
Many of the previous macOS releases were known for battery life concerns — greedy apps, Safari and Chrome draining battery, or power-saving not working. There has been no major battery drain issues reported by the Catalina users so far.
How to fix:
Just to make sure you don’t encounter the problem as well, here are a few precautions:
- Check for apps that use significant energy. For a quick insight, check Apple’s in-built Activity Monitor. It shows the “Energy impact” for every application — calculated based on CPU, network usage, and other factors.
- Have a solution for battery health monitoring. iStat Menus is a perfect fit if you need detailed analytics on disk activity, CPU usage, battery life, memory load, and much more. The app shows all the data right in your menu bar. Plus, you can customize what’s being monitored flexibly.
- Use Screen Time to limit the use of apps. This is the brand-new app on macOS Catalina, which helps you live a healthier Mac user life. Set time limits for the use of specific apps or app categories and schedule downtime. The main goal is to track how much time you spend on the computer, but you can also use it to optimize battery life on Mac.
Apps not working on macOS Catalina
In the attempt to speed up your Mac’s performance, Apple is killing 32-bit app architecture with the release of Catalina. This means you have to switch to 64-bit, for good. You might see the messages like this when trying to launch an app:
The chances are it’s one of the oldies.
How to fix:
![Drive Drive](https://media.idownloadblog.com/wp-content/uploads/2019/08/macOS_Catalina_share_options_004.jpg)
CleanMyMac X can pretty much solve every app problem on macOS Catalina.
Uninstall all 32-bit apps in a click
No more digging through the settings. Download CleanMyMac X and batch uninstall every outdated app on Mac.
- Use Updater to search available app updates. Maybe the app is not working, because it needs upgrading. If you’ve missed the update notification, you won’t know about this. To solve the issue, CleanMyMac X will show you the full list of apps with available updates from developers. The best thing is you can run a batch update right in the app.
- Uninstaller gives you an easy way to reset or get rid of 32-bit apps. The Apple way of checking for 32-bit applications is quite easy: access About This Mac > System report > Applications. However, once you find apps with the outdated architecture, you’ll have to go and uninstall each of them separately. The Uninstaller feature in CleanMyMac X simplifies things for you — filter by 32-bit and get rid of each of them.
- If there’s no particular reason an app misbehaves, try resetting it. Guess what, CleanMyMac X has it covered too. In Uninstaller, click on the arrow button next to the app and choose Reset. As easy as that.
While app notarization takes time, you can expect many apps being unavailable after the release of Catalina. This doesn’t mean they are gone for good, though. Contact developers or follow official developer announcements to find out about compatibility plans.
OneDrive client problems on Catalina
Due to Catalina’s new security settings, Microsoft’s OneDrive may have a problem accessing your drive — even if you allow a full access. This is because macOS 10.15 comes with two disk volumes by default.
How to fix:
There are no surefire fixes just yet, but you can try to troubleshoot OneDrive by setting it up from the very beginning. This worked for some users, according to the Reddit discussion:
- Unlink your account and quit OneDrive.
- Remove OneDrive client from your Mac and delete the folder.
- Set up OneDrive again and make sure you allow full disk access in Security & Privacy.
iCloud problems on macOS Catalina
The most common issue with iCloud is that users are unable to download their folders. You can try downloading iCloud files separately — but that’s going to be a pain if you have an extensive library.
How to fix:
The best fix would be using Forklift app for your file management. The app is Catalina-ready and allows connecting local drives, Dropbox, iCloud, and tons of other storage sites.
If you’re setting up iCloud, there might be another issue standing in your way: Not being able to agree to the Terms and Conditions. The window will just keep popping up on your screen. An easy way to fix this would be to access System Preferences > Internet Accounts and then click on the iCloud icon. You’ll see a static Terms and Conditions window — click Accept and you’re good to go.
Replacing iTunes on Catalina
The new macOS 10.15 brought along the end of iTunes and the birth of the new Music app. Basically, it looks the same — but with music-only content. There’s a huge difference for people who rely on syncing Apple Music with third-party apps. The new app doesn’t support XML file support, which makes playlist syncing impossible across many apps. So if you use Apple Music for DJing, you’ll definitely have a problem.
How to fix:
The only fix to suggest here would be to stay away from Catalina if you need your XML apps to work with iTunes.
Music library issues
New Music app keeps freezing
There have been reports about the new music app freezing on Mac. Well, it’s the first splitting of iTunes, so it’s no wonder it doesn’t go smooth. In most cases, your Mac will keep showing the “library updating” status.
How to fix:
- Create a backup of your entire music library.
- Move your music out of the music folder.
- Go to ~/Library and remove every file related to “Music” and “iTunes.”
- Delete music caches in ~/Library/Caches.
- Restart your Mac and try to access the library again. It should be working now.
Memory usage problems with Apple Music app
Another problem you may come across is the Music app eating too much of your space. One user wrote the app used over 30GB of memory on his Mac.
How to fix:
Apparently, the problem is related to the memory management of Album Art. It is getting better, though. According to user reports, memory usage goes back to normal after restarting the app.
Mail search is broken
According to forum posts, your mailbox might get pretty messy after the upgrade — with no search functionality whatsoever. So if you try searching by keywords or recipient/sender name, the app will keep showing the numerical number of results. The reason could be the new Spotlight integration.
How to fix:
- Open System Preferences > Internet accounts and remove your mail account.
- Restart your computer and once again add your mail account to the app.
- Try searching through your emails — it should be working now.
There have also been some early reports about emails missing from the Mail app — so you might want to wait for it to get fixed before upgrading, especially if you rely on Apple Mail.
Slowing down and overheating macOS Catalina problems
So here’s the thing: macOS Catalina should be faster than Mojave. 32-bit architecture was one of the things slowing an operating system down. It’s gone, and so are the issues with slow apps. Unfortunately, you can expect your Mac go slow and overheat anyway.
How to fix:
- Too many login items often cause your Mac to go slow. To eliminate the problem, disable apps from launching at startup. Go to System Preferences > Users & Groups > Login Items. Check the apps you don’t want to run at startup and click on the minus button.
- Reset SMC. This is a universal fix that helps solve the issues with overheating, battery life, slow Mac, and more. The process is pretty simple and doesn’t impose any risks of losing your data. To reset, shut down your Mac, but leave a charger plugged in. Hold Shift + Ctrl + Option + Power button for about 10 seconds. Click on the power button and wait for your Mac to start up.
Dock disappearing on macOS Catalina
On the Apple forum, people mentioned Dock disappearing from their screen after upgrading to Catalina. The nature of this mistake is unknown — some users connect it to PRAM resetting, the others say they had the issue when trying to work across two screens.
How to fix:
Try Option + Command + D. If it doesn’t work for you, do the following:
- Go to Settings > Dock
- Change the Dock’s size so that it starts flickering
- Change the hide/show settings
- Customize the Dock’s position on screen (you can do it randomly).
Close the window and check whether it’s working now.
Internet not working after upgrading to Catalina
Mac Os Catalina System Requirements
If you’re putting macOS 10.15 over your current system, you’re likely to encounter Internet connection problems.
How to fix:
The radical way would be to clean install macOS Catalina — it’s healthier for your Mac and will probably fix the issue. If you’re not ready to take a risk, try rebooting your Mac.
There has been a user report saying that Sophos caused the problem of network connection. So uninstalling it may be a fix as well.
Bluetooth not available on macOS Catalina
Well, that’s a problem. Definitely a huge one if you use AirPods. Deleting your Bluetooth.plist files might be the way to solve this.
How to fix:
- Open Finder > Go > Go to Folder
- Type Library/Preferences
- Find a file with the name “com.Apple.Bluetooth.plist” and delete it.
Safari extensions not working
While Apple is trying to transition to iOS-compatible extensions, it gradually deems support for many web extensions formats. On Catalina, you’ll face the problem with .safariextz files not working.
Mac Os Catalina Change Drive Permissions Windows 10
How to fix:
Just like with 32-bit apps, there’s no way to fix the missing extensions. If you can’t find a good alternative, you can switch to Chrome or another browser.
Install Mac Os Catalina
Storage filling up too fast
If you notice unusual storage filling up progress, this might mean your Mac captured too many redundant files during the Catalina installation. In most cases, these are APFS files and Time Machine backups.
How to fix:
If you can use a good Time Machine alternative like Get Backup Pro throughout the upgrade, do it. Otherwise, you can remove Time Machine leftovers after installing Catalina with CleanMyMac X. In the Maintenance tab, select “Time Machine snapshots thinning,” and run a cleanup.
To remove snapshots manually, use the following Terminal commands:
1. To view the list of snapshots:
tmutil listlocalsnapshots / tmutil listlocalsnapshots /System/Volumes/Data
2. To delete snapshots:
deletelocalsnapshots
Here’s a quick review of all mentioned fixes, which you can take with you:
Is macOS Catalina stable?
The short answer is yes — if you use it right. So before you decide to downgrade back to Mojave, make sure you’ve done the following things right:
- Backup your Mac with Get Backup Pro or any other reliable tool before running an installation.
- If you still need some of the Mojave functionality that won’t be available in Catalina, install the new macOS on partition.
- Make your Mac as clean as possible before upgrading.
- Get iPadOS 13 if you want to use the Sidecar feature.
- Get rid of 32-bit applications, even if this means killing your darlings.
- Backup your Music and then empty the folder along with music-related Library caches. The new Apple Music app is still pretty much unpredictable, so you need to ensure you don’t lose your playlist.
- CleanMyMac X is a solution for many Catalina issues, so you need it — badly. To cut the cost, you can get it through Setapp and receive extra tools like Get Backup Pro and Endurance.
