Reset Home Folder Permissions and ACLs to defaults in macOS Sierra?

I had the same problem on my Macbook running macOS Sierra version 10.12.2

This is how I fixed it.

I accidentally changed the permissions on a disk so that one or more of the permissions were set to No Access, and I can't see the disk to change the permissions back. How do I fix this?

Follow the step below:

Restart with the Command and S keys held down, and enter the following commands:

mount -uw /
chown root /
chmod 1775 /
exit

--

After the last command "exit" your system should restart on its own and everything should appear the same as the time before you changed the Home folder permissions.

The method has indeed changed once again for Sierra. The new method is to boot to the recovery partition, open Terminal and type repairhomepermissions. This will open up a window similar to the password reset window, but for resetting the permissions on user accounts.

If you search the forums for the topic and limit it to posts by Linc Davis, he has posted a script that will reset everything.

I can never find anything I search for here, so you are going to find it just as fast as I would. It is irrelevant that it is Sierra or any of the other OS's. The process is the same. Linc has apparently stopped posting here, so you won't find anything by him relating to Sierra.

I managed to find one: Re: Re: El Capitan Beachball, Etret

Thanks Barney.

The instructions seem geared to El Cap though so perhaps they removed the feature for Sierra.

Anyone found a way to reset home folder permissions and ACLs in macOS Sierra?

They have nothing to do with El Capitan, Sierra, Snow Leopard, or whatever OS. They are unix commands that adjust the standard POSIX permissions and Access Control Lists. The instructions posted have no bearing or dependence on a "feature" in or not in Sierra.

Apple may have changed some of the permissions on the home folder or its subfolders, but I haven't noticed any obvious differences.

Hi nowak66,

I ran into the same problem. The solution is to boot recovery partition of 10.11.X and reset ACL with the old password reset utility.

I have tried using resetpassword utility on several recovery partitions 10.9 & 10.10 & 10.11 but it did not help me.

What helped is instructions linked few posts up by Barney-15E originally written by Linc Davis

Thanks for finding that. Very helpful.

This finally fixed my issue thanks a lot!

Thank you!! After trying numerous methods (posted here and elsewhere) over the last couple of days, this did the trick!

WHY the **** are you all writing about repairing permission in El Capitain, when the problem is to repair permissions in SIERRA ?????
