I just had to reboot for the first time in weeks... after the reboot, I noticed that two elements were missing from my dock: Unity3D and my Terminal (more precisely, they had been replaced with interrogation marks).
I went to look for those apps in my filesystem, and there's no trace of them anywhere. I have no idea how, when and why they have been removed.
But I need my Terminal for my work.
I've already tried alternatives for OSX's terminal, and none of them are really what I'm looking for... but the original one is by far the closest to what I want. How do I get it back ?
Thanks.
EDIT: Interesting point: I tried installing alternatives for the terminal... unfortunately none of them launched. I'm thinking there's a component needed by terminals that has gone missing as well. I also noticed the System Monitor is missing as well.
/Application
folder, and look for the applications at a time when they were there... well I went over all the backups that I could: the applications are still missing, even a week back, despite the fact that I've been using them daily for months.
