From 10.6.8 to Yosemite in one leap?

Newby here. Can I install Yosemite from 10.6.8? My Mac has all the RAM and hard disk space required, but I'm worried that 10.6.8 is too old to jump all the way Yosemite.

You can certainly do it. But with out your computer specs…no way we can tell you if it will run well. And if you have important apps that are compatible with 10.6.8…I can almost guarantee you they won't be compatabile with OS 10.10 "Yosemite" (4 OS versions newer).

Sorry, my machine is an IMac (iMac10,1) with Intel Core 2 Duo processor, 4 GBs memory and lots of disc space. It came with 10.6.8. I run mostly Apple apps, including iWork'09. That help?

Your iMac can sure run Yosemite, but respectfully suggest increasing the memory to 8GB which is what most recommend for Yosemite. Some older PowerPC applications will no longer run on anything later that Snow Leaopard OS X.6, including Office 2004 etc.

Backup everything first to an extarnal drive and download Yosemite from the App Store.

Got it. Thanks.

Erase OS 10.7 and re-install OS 10.6?

This is related, I think, but I made a mistake by installing OS 10.7 and I'm going to rid it off my hard drive if the last thing I do.

Can anybody help me figure out how to do that?

You'd do better starting a new thread, and include some more details when you do. OS X versions, Mac model etc. and some facts as to why may even help.

Hey if you need help go to www.ifixit.com there tutorials for that model will help you upgrade your ram.
