System unusable post 2016-001 security update
So I updated my system from the App Store with the El Capitan 2016-001 security update, and now my system is pretty well hosed...
To summarize the issues:
- Finder windows take forever to update/refresh (spinning beach ball and gears forever)
For example, when I clicked on "Applications", the applications list was incomplete and most had generic icons
- I get the following error message when trying to launch any application, including System Preferences:
"The application is damaged or incomplete"
Those are the most salient and obvious issues. I can't launch Terminal, Disk Utility, System Logs, nothing, from my primary user ID, which is an admin ID.
Steps I've taken:
- I logged in using a test account and no issues.
- I booted into Safe Mode with the affected ID, same issues as when booting normally.
- I've run Disk Utility First Aid from the test account, and it reports the disk is fine, but I'm not sure if it's looking at the affected user account.
- I've run the unified installer from the test account
I'm kind of at a total standstill. Does anyone have any ideas how I might proceed? I'm hoping Linc or Barney F15E have some ideas...
Help!
Thanks - Dave
