Hi, I am an experienced Unix/Linux system admin, but quite new in the Apple world. I've just got this MacBook (Mac OS 10.6.8) from my company and have admin rights of this system. Issue: I can't remove icons from dock because it is locked. I've googled a lot but unfortunately haven't found the solution yet. I've tried Parental Controls, terminal commands, etc. but none of them working. Does Mac use user profiles to control what users can do? If yes, where can a find and modify user profiles? I'll try not to use any third party software for this 'simple' issue. Please help! Thanks a lot in advance!
