Reverting yosemite back to snow leopard

[johns0]

I'm going to restore a customers apple computer back to snow leopard and just need to know if there's any activation issues as the system was preloaded with snow leopard,going to wipe the hdd and install fresh.

Macs usually have an OS requirement of at least the version that it shipped with. I.e. don't try to load anything before Mac OS X 10.6.7 on an early 2011 MacBook Pro. And do get the updates to the latest SL version (10.6.8); the built-in Software Update can take care of that.

The customer found her original snow leopard install disc so i was able to restore it.

People usually do this because some program doesn't work under the new OS. Usually there are ways to deal with that (ie. upgrade the program, find a replacement, etc.). I suppose you should warn her that Snow Leopard no longer gets security updates. Apple drops security fixes on OS X versions once they get 3 releases behind the current one. Snow Leopard was dropped last year. Apple doesn't particularly go out of their way to publicize this dropping of old versions, but they do constantly push customers to update their versions of OS X when new ones come out.

I did tell her that 10.6 stopped getting new updates but she was much happier being back with it.
