There was a bug under Mac OS 9 (and maybe Mac OS 8 too?) that, under a special circumstance, prevented some files to be locked, unlocked or even deleted. They would sit there in your trash forever and prevent you to empty it even when the OPTION KEY is held down. Rebuilding the desktop does NOT resolve the issue. Trying to get file info with ResEdit results in the following error: The reason this is happening is generally due to the file type/creator code not being set properly or at all, which highly confuses the Finder. These files usually come from the internet (such as .iso files) and are generally transfered using a FAT32 (DOS) or NTFS (Windows) partition which does not store any resource fork (so no file type/creator code) to begin with and increases the chances of this happening. To resolve this issue: 1) You need to use a file type/creator changer app, such as: Creator Changer 2.8.4 2) Launch your type/creator code changer app and select the problematic file. If the file is locked, it will probably complain it will not save changes, but guess what: It actually does and it will work, so proceed. 3) You will notice that both type and creator boxes are currently empty, which is not supposed to be with any valid file on a Macintosh volume. This is how you will fix the issue: Type '????' (4 interrogation marks) in each of the 2 boxes like the following and apply the changes (click OK). Now, your file will have a default file type/creator code and it will be seen as valid by the Finder, allowing you to lock, unlock and delete the file. Moreover, you will now be able to get file info with ResEdit and use/edit the file's resource fork as you please! Cheers! :D |
If you have a Mac (mid-2013 or later) with macOS 10.13 or later, your Apple Watch can instantly unlock your Mac when it wakes from sleep. You need to be signed in to iCloud using the same Apple ID on both your Mac and Apple Watch. Tap to Unlock Tap to Unlock is an innovative way to unlock your Mac by tapping a custom tap pattern into your Magic Trackpad or Magic Mouse.
Since updating Apple Watch to watchOS 7, it’s possible Auto Unlock with macOS stops working. This is due to a bug with the credentials stored in macOS used to authenticate the Handoff. You can reset these stored keys in Keychain Access to reset the Auto Unlock functionality.
Delete Keychain entries
Open Keychain Access.app from the Utilities folder in Applications. Choose View → Show Invisible Items. This will show all items in the Keychain, including the entries relating to the Auto Unlock functionality, which would be hidden otherwise. If you can’t find the items in subsequent steps, check that this is toggled correctly and not accidentally unset.
Search for ‘auto unlock’ and some application passwords should appear. If not, skip this step, but if some exist, delete all the ‘Auto Unlock’ items. These items are within the iCloud keychain so they are synchronised to other Macs you might also be signed in to, so Auto Unlock will be invalidated and disabled everywhere.
Now search for ‘autounlock’ and you should see some entries with that name. Delete all ‘AutoUnlock’ entries. Some of them might be regenerated shortly after deletion.

Delete preferences
Go to the Library folder in your home folder, open Sharing, then AutoUnlock. Delete both preference files within. If you can’t find the folder, double-check you’re looking in the Library folder within your home folder, not at the root of the boot volume — see the path at the bottom of the screenshot below.

Restart, then try to re-enable Auto Unlock in System Preferences. Hopefully these steps should get everything back to normal.
