Chapter in this post:
The new operating systems from Apple and the new Apple Silicon Macs have a few special features in store. Among other things, the procedure for repairing access rights, which is used to correct the system's authorizations, has changed.
I've read through a few instructions and just introduce you to the options that I have found. You have to try out what leads to your goal.
The first variant is to run two commands in the Port. You can find the Terminal in the Applications > Utilities folder. There you type in:
sudo diskutil resetUserPermissions / 'id -u'
Note: In the terminal you will be asked for the admin password after every "sudo" command.
It is possible that the error "Error -69841" is then displayed. This can be solved by entering these two commands:
chflags -R nouchg ~ sudo diskutil resetUserPermissions / 'id -u'
Another way to repair the access rights in the user's home folder is also via the terminal. This time, however, im Recovery mode, which you can reach by holding down cmd + R when restarting on Intel Macs and holding down the power button on Apple Silicon Macs (such as M1, M1 Pro / Max) (see Recovery mode on Apple Silicon Macs). Proceed as follows:
If all else fails, the last variant remains, which is unfortunately more cumbersome: You start from scratch and migrate your user data to a completely fresh system.
I hope everything will work again afterwards. If not, maybe we can try the topic again Sir Applerot Forum approach.
