I want to uninstall OS X El Capitan, which keys do I press and in what order so as to complete a total clean of the HD, Any help would be appreciated.
Mac mini, iOS 9.2.1, EL Capitan operating system 10.11.2
Hi Illaass, thanks for your reply, a lot of information in the links, not yet had time to read fully but will respond when I have.
Hi again, managed to read the literature, but this still leaves me with some nagging doubts! What I am wanting to do is uninstall Capitan and revert to Yosemite,at the moment at least, Capitan is nothing short of a disaster, problems to numerous to mention here.
The procedures I have looked at seem to suggest that unless you have made a time machine backup of Yosemite prior to upgrading to Capitan the erase of the hard drive and reinstallation of Yosemite will not work!
At the moment I have a download of Yosemite from the apps store sat in my Applications folder. My plan is to make a bootable USB flash drive (found a good procedure for this ), delete the Hard drive and reinstall Yosemite. Any help appreciated, thanks.
Yes:
download Yosemite for the Purchased section of the Mac App Store and the make a bootable USB install media using
and then boot from that and format the internal drive and install Yosemite
Hi again Illaass, thanks again for the info, never heard of Diskmaker X before, what a smart bit of kit! it does the whole procedure with just a few clicks, I now have bootable copy of Yosemite, I don't know if you have used this App yourself but just one comment, when it started to copy the files the progress bar in the box did not alter until the very end (about 10mins in total).anyway so long as it has worked its just a minor point.
Have to move some files before Yosemite reinstall, will update you later , Thanks Again.
I have been using DiskMaker for years. I Just start it and come back later. It does take a while
Hi Illaass, just to let you know, I now have Yosemite back on my Mac Mini, all appears good,so many thanks again.
