If you need permission to open an item on Mac
If you don’t have permission to open a file or folder, you may be able to change the permissions settings.
On your Mac, select the item, then choose File > Get Info, or press Command-I.
Click the arrow next to Sharing & Permissions to expand the section.
Click the pop-up menu next to your user name to see the permissions settings.
If you’re not logged in as an administrator, you may need to click the lock to unlock it, then enter an administrator name and password (or use Touch ID or your Apple Watch).
Change the permissions to either Read & Write or “Read only.”
If you can’t change the permissions, contact an administrator of your Mac or the owner of the file or folder.
Thanks for your feedback.
