I decided to go with a fresh install of Lion at the weekend on my iMac and Mac Mini and came across a strange bug...


Basically, when changing sharing settings it seems to 'corrupt' a user's preferences. This 'corruption' is evidenced by not persisting (after a reboot) say the removal of a dock item or changing what the sidebar displays in Finder. If I make a change like this (or a series of changes) and restart my machine the change(s) made since last restart are reverted.


I came across this issue when undertaking the following:

 

  • On iMac: Shared out an attached hard drive that I use for Time Machine (so I could use the same drive for Time Machine on my Mac Mini)
  • On iMac: Changed the permissions on the 'user' folder so that Mac Mini could see it.
  • On Mac Mini: Changed the permissions on the 'user' folder so that iMac could see it.
  • On Mac Mini: Enabled screen sharing.

The above actions resulted on the 'corruption' of the user preference file(s) on both the iMac and Mac Mini.

 

I found nothing on Google and as I couldn't sort I re-installed Lion and performed the following actions:

 

  • On Mac Mini - Changed the permissions on the 'user' folder so that iMac could see it.
  • On Mac Mini - Enabled screen sharing.

 

Again, the above actions resulted on the 'corruption' of the user preference file(s) on the Mac Mini.


I then tried creating a new user account and making the desired permission/screen sharing changes. More specifcally, I did the following on a clean Lion install:

 

  1. On Mac Mini: Set Up a NEW Administrator Account.
  2. On Mac Mini: Reboot.
  3. On Mac Mini: Log In with NEW Administrator Account.
  4. On Mac Mini: Changed the permissions on both 'user' folders (DEFAULT & NEW Administrator) so that iMac could see it.
  5. On Mac Mini: Removed 4 unwanted icons from the dock.
  6. On Mac Mini: Reboot
  7. On Mac Mini: Log In with NEW Administrator Account to find that previoulsy deleted icons had reappeared.
  8. On Mac Mini: Reboot
  9. On Mac Mini: Log In with DEFAULT Administrator Account.
  10. On Mac Mini: Removed 4 unwanted icons from the dock.
  11. On Mac Mini: Reboot
  12. On Mac Mini: Log In with DEFAULT Administrator Account to find that previously deleted icons had reappeared.

Sorry for the long post but the devil is in the detail. If anyone has any ideas as to how to solve or is able to replicate the problem I'd been keen to know.


iMac, Mac OS X (10.7)
