Why can't I install El Capitan now that Sierra has been released?

I'm running 10.8.5 on a mid-2011 iMac. I really don't want to upgrade to Sierra on an older machine and risk having a lot of problems on a first release, so I was looking to upgrade to El Capitan. Why has Apple removed that option?

iMac (21.5-inch Mid 2011), iOS 10

A small number of users are affected by problems after a first release; the vast majority are not.


What you can do is partition the hard drive, and then on a secondary, small partition, install Sierra and see how it works. Be sure to make a Time Machine backup before partitioning. If you are not sure how to partition, see: Disk Utility (El Capitan): Partition a physical disk.

THANK YOU for clueing me in to the fact that I could get Yosemite from the "Purchased" part of the Mac App Store. I have an old early 2008 iMac that is seldom used and is still running 10.7 Lion. To use a newer version of an app I needed to upgrade the iMac to a newer version of Mac OS X... and was frustrated when the only option on Apple's site was for Sierra, which will not install.


Thanks to your tip I'm downloading Yosemite right now. (I'm also downloading El Capitan courtesy of the next message below from stevejobsfan0123.)
