I have iphoto version 9.3.2..Can i upgrade straight to version 9.4.2 or do i need to go through the older versions first??
If you have OS X Lion 10.7.5 or OS X Mountain Lion 10.8.2 or later, you an directly upgrade to 9.4.2.
As always, make sure you have a working backup of your iPhoto Libraries and your system before upgrading.
