Had the Macbook since April 09. Decided to try iPhoto even though I'm very used to Picasa. Loaded up Picasa side by side with iPhoto. Both programs worked with no problems, however, I have found iPhoto to be seriously lacking and want to get rid of it. I have over 28,000 photos and all but the most current are on an external 1tb hd formatted fat32. All info backed up. Using AppCleaner I deleted iPhoto. Then attempted to use Picasa but get a spinning wheel and splash screen for about one minute then Picasa starts in a small window and within 30 seconds Picasa shuts down. I tried: *Reinstalling Picasa *reinstalling iPhoto *reformatting external hd to mac journaled *reinstalled Picasa Nothing seems to work. Anybody have any idea???
