A while ago, I attempted to install Wine on my mac. This involved installing Xcode. Afterwards, I was distracted and never tried to do anything with Wine, so I have no clue whether it was successful or not. (I used this tutorial.) The next day, I tried to run GIMP, as I had thousands of times before. However, after the GIMP icon appeared in my dock, no X11 icon followed it, and GIMP failed to work. I attempted to launch X11 from it's .app, but there was no response. The GIMP icon continued to sit in the dock, doing nothing until I force-quit. Just today, I decided to do something about it. I decided that uninstalling X11 and reinstalling it would probably solve the problem. First, however, I decided to uninstall Wine and Xcode, thinking this might help. So I uninstalled wine using the same tutorial. Then, for some reason, I decided the best way to get rid of Xcode (which I had never bothered to take a look at) was delete the entire "Developer" folder from my hard drive, which I was pretty sure was new. As soon as I had done so, I realized it was probably a really stupid thing to do. After all this, X11 and GIMP were unsurprisingly still broken, so I went on to reinstalling X11. The first way I tried removing X11 was to simply delete it from the Utilities folder. I was met with a "You cannot delete X11 because it is running" message, so I went online for help and ended up following this tutorial to remove X11 via the terminal, along with the other things that accompany it. I then reinstalled X11 from my OSX install cd (I'm running 10.5.8 but the CD's a little over a year old and contains 10.5.2). Now things seem even more messed up. Attempting to run GIMP results in a momentary dock icon and then the message, "The application gimp-2.6 quit unexpectedly." Attempting to run X11 results in this dock icon and window: Spoiler Running GIMP via the terminal (in the way explained in the sticky in this very forum) has this result: Spoiler Alright, I've given a truckload of information here, and a giant wall of text, but I'm hoping that somewhere in this mess there's a clue that a more knowledgeable person can use. If there's a better place than here to ask about this sort of thing, I'm open to a referral, but this seems like the sort of problem that you guys would know about. Thanks for your time!
