Cannot open GarageBand 10.4.2 file in El Capitan 10.2.0.
It seems that I cannot open a GarageBand 10.4.2 file in my old GarageBand 10.2.0 version. I am stuck on El Capitan on my mid-2009 MBP and I cannot upgrade to the later version of GarageBand. Can you please confirm if I have a compatibility issue and if so, is there anyway to workaround this?
