2 questions: 1) I was able to download 10.7.4 developer build. When 10.7.4 officially released I wasn't able to update to the official build and I downloaded the combo update from Apple's website. Is this a problem? Installing above 10.7.4 the combo update? or everything will be fine? 2) I downloaded Safari 5.2 update 3 and now I can only uninstall update 3 to go to update 2. Further uninstallation isn't possible. Any ideas to go to official 5.1.7? and why after installing the combo update I still have 5.2 Safari? Thanks.
