• Close all applications and files before attempting the repair.
• Make sure you have enough permissions to read and write to the drive you want to modify.
• Run a scan to check for the presence of malware. Delete any malicious software detected using your antivirus and delete all related files.

• Declutter your system by cleaning up your computer with a Mac cleaning tool. This should fix any errors related to corrupted junk files or cached data on your Mac.

1. Connect the USB boot drive to your Mac, then reboot.
2. While restarting, hold down the Option key button and choose the attached boot drive.
3. In the boot menu, choose Disk Utility.
4. Click First Aid at the top menu to verify the disk.
5. Once your disk has been verified, you can then proceed with the task you were trying to perform when the error occurred.

Solution #2: Use the Recovery Partition.

If the 'Couldn't Unmount Disk' error message appears when doing First Aid on your disk or formatting a non-boot disk, the first solution will not work. If this is the case, you can try resolving the error using Recovery Partition.

Here's how to do it:

1. Reboot your Mac.
2. While booting up, hold down the Option key to boot using the Recovery Partition.
3. Next, click on Disk Utility from the boot menu.
4. Click First Aid to verify the disk or select Erase to format the disk if needed.

Solution #3: Use Command Prompt to Force Unmount the Disk.

If the above methods don't work and your disk is pretty stubborn, you can attempt to fix this error by forcing to unmount the disk using commands.

To do this, follow the steps below:

1. Launch Terminal by navigating to Finder > Go > Applications > Utilities.
2. In the Terminal window, type in the following command: diskutil list
3. This will list down all the available disks on your Mac.
4. Look for the disk that you want to force unmount and take note of the number of the drive.
5. Type in this command next: sudo diskutil unmountDisk force /dev/diskx
6. Replace /dev/diskx with the disk number of the drive you want to unmount (for example, dev/disk1).
7. Wait for the process to be completed.
