So, I have OS X el capitan 10.11.4. And I want to revert to OS X Yosemite.
I have a Macbook air 11 inch. I want to revert without a Time Machine.
Thanks.
MacBook Air (11-inch Mid 2012), OS X El Capitan (10.11.4)
The only possible way without Time Machine is to erase and install through internet recovery. This will install the original operating system that shipped with the computer. You can upgrade back to Yosemite by downloading Yosemite through the Purchased tab in the App Store.
This will erase everything from the computer, make sure to backup any important data first.
I would think creating a Yosemite Bootable USB installer should work unless I'm missing something.
And how can I do that?
One way: Create a bootable installer for OS X - Apple Support
You can also use DiskMaker X.

Yes, but it would still require having to erase first.
Yep. A backup should be made. I do think it would be faster than doing an Internet Restore. I have a fairly fast connection and it's still slow.
how can I revert to os x yosemite from el capitan
