They should not have released an OS prematurely, but they did. Um, I don't think my APPLE PASSWORD MANAGER that keeps popping up with an error is a 3rd party app...next?
Oh, and Leopard didn't cause a fraction of these issues for me, nor are the apps I am having issues with listed. Sorry that I trusted Apple to be as awesome as they claim to be in those self-indulgent ads which are somewhat like their worshippers here.
So wait, your password manager is the only Apple related issue and you scream that Snow Leopard is a failure when so many others are having very positive experiences ?
For your information, Xtorrent is known to work, maybe you just don't have the latest version, did you even try downloading a newer version and see if that works ? For Maya, did you bother to look at compatibility information ?
Again, what is stopping you from either trying a clean install of Snow Leopard to see if your issues are upgrade related or just going back to Leopard and waiting ?
If you can't live with a few incompatibilities and bugs, don't upgrade to just released software. The testing process of software on the complexity level of an OS can never trap all bugs. There are just to many variables and different configurations out there. This is the exact reason why IT departments don't just upgrade on day 1.
Consider this a lesson learned. At least you won't have to pay for Snow Leopard later when your issues are resolved.
