Q: How to uninstall Yosemite 10.10.4 and go back to Snow Leopard

Revert to a Previous OS X - Yosemite
If you do revert, I'd use Setup Assistant to restore your data. This process takes a while, so do it when you won't need the computer for several hours, based on my experience.

When you say make two backups do you mean 1) one of the files added after Yosemite and 2) one of the files before Yosemite or two backups of post-Yosemite files?

Aug 8, 2015 1:43 PMby Eric Root,You are welcome. Since you already have your pre-Yosemite files backed up, you should be able to skip the backup step. I think everyone should have two complete backups, as hard drives do fail. When back in Snow Leopard, I would get another external drive and use either Time Machine or a clone to create a 2nd backup in addition to the one you have.
Clone - Carbon Copy Cloner (Often recommended as it has more features than some others)

Since installing Yosemite 10.10.4 I can't download the photos my external hard drive because I can't access to Get Media button on Photoshop Elements 9 . (This is a PSE problem and I'm waiting for an answer from the Adobe community but if I don't get an answer I will have to uninstall).
PSE 9 is 5 years old, so I doubt that Adobe will patch it. Wouldn't it be easier and more useful to upgrade your copy of PSE to a later version? That way, you would keep all the security fixes, bug fixes, new features and enhancements made since 10.6.
A MacBook running Snow Leopard is at least 5 years old, too. Not vintage by any means, but to be reliant on unsupported software that requires an old, unsupported OS, needing old unsupported hardware is not an ideal place to be.
If your MB stops working, gets lost, stolen, catches fire or drenched with water tomorrow, then how will you use PSE 9 on a brand new replacement?
The use of computers is a constant migration of hardware and OS/applications. But hopefully our data remains eternal...!
