Whoever is in charge at Apple of software development and QAT for Aperture MUST be fired. If not, Apple will loose any credibility they still have with professional photographers. As far as I can tell, they are not doing too well with videographers either, but the photo/Aperture side is a disaster.
Software quality control for Aperture has been a nightmare (remember the massive performance problems we had after the last OS upgrade??!!). Apple, you need to get your act together and rid yourself of the problem before it is too late.
PS: If it is not obvious by now, I am experiencing the same startup crashes everyone else is struggling with. The funny thing is that iPhoto works fine with the SAME libraries that Aperture is copiously crashing on. I guess the iPhoto SW development manager and team are separate from the Aperture one ..... Hey, here is an idea. Fire the Aperture team altogether and give the iPhoto team Aperture. Maybe they can salvage it.
I am trying to put a workaround together .... (hint: it involves iPhoto and removing the .plist that contains the stupid facebook link that never worked properly)
