Trouble upgrading from Mavericks 10.9.5 to El Capitan 10.11.6
Hardware: MacBook Air mid-2013 - 1.3ghz i5, 4gb ram
OS: Mavericks 10.9.5
Tried to update to El Capitan via App Store however the following error pops up:
"We could not complete your purchase.
This version of OS X 10.11 cannot be installed on this computer."
Any way to update to a lower compatible version of El Capitan?
Thanks!
MacBook Air
