About Permissions
Never, under any circumstance, screw with your permissions. Ever. You will break something if not everything.
I was lazy, and I wanted to install Comic Life Deluxe on all of the user accounts on my machine. I run as a limited user, so I didn’t have permission to write to the Library folder. With a couple quick edits in Finder, I change the permissions in every folder in ~/Library. Rookie mistake.
Everything seems to be fine until I go to open Illustrator. Permission denied, bitch. I fiddle around, and it demands that I uninstall and reinstall. I comply, and I am greeted again with a bitchslap. After finding that Adobe’s support team has weekends off, I start searching the archives for some sort of troubleshooting. I find 6 different solutions, so I perform all of them. After three hours of agony, I finally got CS3 back to factory default.
Mind you, the program was still on my harddrive and functioned fine. Their DRM scheme flipped out and wouldn’t even let me deactivate. Their bullshit paranoia screwed me out of three hours, and they weren’t even there to support me. God forbid that the DRM Gestapo decide to beat down your door on the weekend. You’ll be royally fucked.
