Restoring to older versions of Mac OS


the better course is to create on another Mac a bootable Yosemite installer following Dan Frakes’ instructions. Patrick has the Yosemite installer, but if you need an older installer, you can launch App Store on a Mac and then use the Purchased tab to scroll down and find older releases—they don’t show up by searching.

Also useful if El Capitan has so trashed your Mac that insects trapped in amber move faster.  Not that I'd know anything about that.
