    Hello everyone,

    I'm new to mac and i just installed some programs yesterday. Because I have a 64GB MBA I thought I should delete some stuff and I guess I accidentally deleted some system files. Now my MBA doens't operate proper and I can't open anything. Finder crashes all the time and I can't go trough my stuff. I need my schoolstuff back..

    Is there anyone out there who can help me with this issue?

    Halit

    You can do a repair through the recovery partition (hold alt on startup, boot into Recovery). Then do 'Reinstall OS X'. That does a 'repair install' which basically reinstalls all of OS X's core files without affecting your data.

    Stop deleting things

    If you have another computer, you could try target disk mode by holding down T at startup. It essentially turns your computer into a hard drive, and you can find your files that way.

    Also, if you entered your password when prompted, you didn't "accidentally" delete anything.
