The “You don’t have permission to save files to this location” error message may appear due to permission issues, read-only files, or corrupt files.
Macs use two types of permissions, UNIX file permissions and access control list (ACL) permissions
Resetting the disk permission can reset the permissions for all system-level files using the Repair Disk Function.
The reset password tool can help repair the user account’s home directory permissions back to their default settings.
Ensure that the app trying to save the file has full disk access to troubleshoot this error on your Mac.
Some files are restricted by the user and require adjustments to the read/write permissions for third-party applications on Mac to access them.
Renaming the file can fix a “You don’t have permission to save files to this location” error if editing or saving files is not possible.
If a user permission change makes the important data inaccessible, it is recommended to use reliable data recovery software for Mac to recover lost files.
Reviewing Mac permissions during issues is always a good idea as your Mac won’t automatically repair permissions except while installing an OS upgrade.
Backing up your data on an external drive or Mac’s in-built Time Machine is highly recommended.
