I have a late 2009 iMac with a 3.06 GHz Intel Core 2 Duo processor. I am running OS X Lion 10.7.5 and would like to upgrade to OS X El Capitan. When I try to purchase OS X El Capitan 10.11.6 via the App Store, I receive the following msg from App Store: 'We could not complete your purchase. This version of OS X 10.11 cannot be installed on this computer.'
I have >420 GB memory available on my hard drive and El Cap 10.11.6 only requires >6 GB.
The App Store info about El Cap 10.11.6 says 'Compatibility: OS X 10.6.8 or later', so my iMac should be compatible with this OS X.
Do I need to first upgrade to a different OS X? Which OS X?
