iPhoto 7.1.2 is described as:
This update addresses issues when publishing photos to a .Mac Web Gallery, improves overall stability, and fixes a number of other minor issues.
iPhoto 7.1.2 also contains a security fix to prevent arbitrary code execution.
The ProKit Update is described as:
This update improves reliability for Apple’s professional applications and is recommended for all users of Final Cut Studio, Final Cut Express, Aperture, Logic Studio and Logic Express.
I didn’t have a problem installing either update but I don’t use .Mac Web Galleries. No reboot was required.
Well, I almost had a week without an Apple update. But I think all my Apple software has been updated so hopefully things will quiet down.
