disk utility repair disk permissions mac os 10.12

Your Mac contains a database of permissions. You can view a file or directory’s permissions by holding Ctrl and clicking the file or directory in the Finder, clicking Get Info, and looking under Sharing & Permissions There are also more modern access control list (ACL) permissions. There are standard UNIX file permissions, the same sort of permissions you’d find on Linux. Macs have two different types of permissions. If you have multiple user accounts on your Mac, permissions keep each user account’s files private from other uses. A program you run on your desktop can’t just modify your system files without permission. It makes me wonder if I should reinstall everything from the start but that takes a lot of hours.Īlso, in Disk Utilities, in the left column where it lists your hard drives, each one has the manufacturer's name, like '189.9 GB Maxtor 6Y200P0', and under that and slightly to the right, the name you gave it.The permission system is a way Mac OS X and other operating systems ensure security.

I've had times before where it took 3 or 4 times to get to the point where no permissions were in need of repair, but this is crazy.

I've done that maybe 10 times and it always repairs tons. When the repairs were completed I ran 'repair permissions' again, and once again, there were another 70 permissions that were 'repaired'. Then, for the heck of it, decided to run 'repair permissions' and there were tons, well maybe 70, of permissions that needed repair. It runs fine now except: I booted from the Snow Leopard install DVD and ran Disk Utility and did the repair disk. I installed Snow Leopard and did the erase everything 5 (or was it 7?) times security option before installing, then did the software updates, and also installed the old PPC version of Photoshop CS I use. I hope the Apple DVI to ADC adapter works with the adapter I have on order. I'll be using it for Photoshop with an external monitor, mouse and keyboard. The screen is cracked (glass only), the trackpad wonky, missing 6 keys and looks like it was used for batting practice but still runs fine. I just bought a very beat up 2.4GHz MacBook Pro 4GB RAM (mid 2010) for $100.
