So, does Safari starts to launch(icon launching feedback in the dock), or does it do nothing at all. Well regardless, find and remove preferences files for safari. Go to the finder and do a search for "Safari." Then delete Safari preference stuff. For example, from looking at the results of my safari search (on OS 10.3.2) I find a lot of stuff. But here is the stuff I would recommend moving to the trash. Primarily, remove com.apple.Safari.plist from it current location it should fix the problem you are having. If this does not fix the safari launch problem, re-do the search again and remove more Safari related items... File Names and Locations {Remove this file first "com.apple.Safari.plist" and try running safari, before going and deleting all} com.apple.Safari.plist (your user folder aka "Home" / Library / Preferences) --------------------------------- If removal of the above file does not solve the problem remove all of following listed including the file above which may or may not re-appear.... {{{ IMPORTANT NOTE An important thing to remember is be careful of what you delete, the files listed here should be safe to remove. If you see more safari stuff on your search use common sense. A good rule of thumb is to not delete stuff that is not originating from your home directory. For Example, on my computer there is a file that is related to safari but not in a important way, some kind of .pkg file, and its location shows that it is a good example of something not to delete. {location starts in the Hard Drive (root level)}. There are also safari folders on my computer that are totally unrelated to safari web browser. MS Office for os x has a Safari office theme, that you don't want to delete. So, again just be careful..... }}} Here are the other files that you should try to delete safely... Safari [Folder] (Home / Library / Safari) Note: that in this folder your bookmarks file is stored, so you may want to keep that file so you can replace it later.... Safari [Caches Folder] (Home / Library / Caches / Safari) This should solve the problem, if not, I can provide some more suggestions later....
