I have a Late 09' Aluminum Mac that needs a new HD and was wondering if this MacOS Sierra would work well on this device? I ask because I don't see how I could install El Capitan on it and would have to do the current Mac OS.
Would it 1) be compatible and 2) would it function properly or would it be extremely slow?
