My Safari closes 5 seconds after I open it. Things I have tried: Deleting all Safari preferences, reset and delete cache. Repair Permissions Install the 10.4.10 update again Install Safari 2.0 (it worked!) Install update AGAIN! (it stopped working) Restore a backup (before it stopped working) - it worked! Ran Software Update - IT STOPPED WORKIN!!! Repaired Permissions, it still doesn't work! OK, I'm tearing my hair out now. The 3 Beta does work, but I prefer 2 for the moment until all issues are worked out. I have dissabled things like Shapeshifter, not installed any extra plugins at the moment. Does anyone have an idea of what I should do?
