Mac os reset permissions

Change permissions for files, folders or disks on Mac

Permission settings determine who can view and alter files on the computer. You change permission settings at the bottom of the Info window for a file, folder or disk in the Finder. For example, you can change permission settings for a folder so that other users who log in to your Mac, or connect to it for file sharing, can view but not change files in a folder.

Assign permissions to users and groups

On your Mac, select a disk, folder or file, then choose File > Get Info.

If the information in Sharing & Permissions isn’t visible, click the arrow .

If the lock at the bottom right is locked , click it to unlock the Get Info options, then enter an administrator name and password.

Click a user or group in the Name column, then choose a privilege setting from the pop-up menu.

Read & Write: Allows a user to open the item and change it.

Read only: Allows a user to open the item but not change its contents.

Write only (Drop Box): Makes a folder into a drop box. Users can copy items to the drop box, but can’t open it. Only the owner of the drop box can open it.

No Access: Blocks all access to the item.

You can undo any changes to privilege settings for a user or group in the Sharing & Permissions section since opening the Info window. Before closing the Info window, click the Action pop-up menu , then choose “Revert changes”.

Apply permissions to all items in a folder or a disk

On your Mac, select a folder or disk, then choose File > Get Info.

If the lock at the bottom right is locked , click it to unlock the Get Info options, then enter an administrator name and password.

If the lock at the bottom right is locked , click it to unlock the Get Info options, then enter an administrator name and password.

If the new owner’s name isn’t listed in the Name column in the Sharing & Permissions section, click the Add button to add the new owner.

Select the new owner in the Name column, click the Action pop-up menu , then choose “Make __ the owner”.

You can undo any changes to an item’s owner in the Sharing & Permissions section since opening the Info window. Before closing the Info window, click the Action pop-up menu , then choose “Revert changes”.

Question: Q: Resetting permissions in Catalina (HT203538)

Years of transferring my home folder from one piece of hardware to another, doing clean installs with restores from a cloned hard drive, first using the ditto command on the command line and then the Migration Assitant with later versions of the OS have likely left permissions in my home folder a mess. I just learned on an AppleCare call that since Catalina this can cause issues that are hard to detect or diagnose.

Support document HT203538 suggests a procedure for how to launch a utility that takes care of the the repair of permissions in a user’s home folder by being launched from the command line, after the computer is booted from the recovery partition. The last step in that process is a reinstall of the OS, in place of the previous installation.

My question to you guys is this: What would happen, if I left that reinstall off and just rebooted the system after the permission repair utility has completed its work?

Seems to me this would be leaving off the last step of the process if you are trying to right the ship.

Repair Permissions in Home Folder

1. Start up in Recovery mode by holding Command-R.
2. Once in Recovery mode, open Terminal from the Utilities menu.
3. There type repairHomePermissions and press Return.
4. That should launch the Repair Home app. Select the correct user account from those offered, and enter the admin password for that account. If that isn’t an admin account, Apple doesn’t explain what you should do.
5. Then click on the Next button.
6. Once that has completed, click on the Exit button.
7. In the main Recovery mode window, select Reinstall macOS, and click on Continue to reinstall macOS in its entirety.
8. Once that is complete, restart in normal mode.

If the above procedure doesn’t resolve the problems, Apple recommends:

1. Ensure you have a full backup of your Mac.
2. Start up in Recovery mode again and erase your startup disk as detailed here.
3. Reinstall macOS.
4. In the subsequent setup, create a new and different primary admin user account with a different name.
5. Use Migration Assistant to restore files from your previous account.

Apple’s detailed instructions are found here.

Question: Q: Reset All File Permissions

I have a problem. I was messing around with file permissions and screwed up some of my root directory folders. Now every users folder is public to anyone and there could be more issues I haven’t found. I can’t find anything on here that suggests any easy way to do this, so I need some help resetting ALL of the permissions on my hard drive (Just to make sure). Unfortunately, disk utility found no errors in the permissions and didn’t correct anything (even in recov mode) and restoring from the backup doesn’t help. I am however very familiar with the Unix command line, so throw anything you got at me.
