Hi all, I need to update my system to use software that requires at least Mountain Lion 10.8 to work. I currently have Lion 10.7. I was thinking of getting El Capitan, which is the latest OS my system will support (Mac Pro early 2008). However, I've read that some people had issues with the installation. Is it safer to just try to install Mountain Lion? I've read some people trying to install 10.11 and it taking all day or longer, or getting stuck in the process, and that maybe older Macs such as mine might struggle with this update, particularly since I've skipped the other upgrades. Any thoughts? Thanks for your input!
