Snow Leopard is awesome, fast, and lightweight.
It’s a shame it will not work with any of my applications.
I have spent most of this day deinstalling Snow and restoring my machine’s OS X 10.5.8, email accounts, applications, and passwords because most of my applications crash to desktop spontaneously.
Look at the compatibility list for your applications first. If you have doubt I would wait until the 3rd party software developers have a chance to update their applications. The latest version of Firefox crashes, too.
Even the latest Apple’s Mail program would crash on me when I tried to save documents.
This is about an 8-hour “Teachable Moment” for me and my business.
