Download old version (10.3.5) of Garage Band, for Mojave

Hi all,

I'm running a 2013 macbook pro with Mojave. I may upgrade computers soon, but I would like to use Garage Band now, and I cannot upgrade beyond Mojave at this point. Only Garage Band 11 is available in the App Store, and I need 10.3.5. (On Reddit, someone said, "well, this happens all the time for lots of people, so I'm sure there's an easy answer." HAHAHAHA!)

So -- other than torrenting from some random site, any ideas? Does Apple make older versions available? (How reasonable would that be....)

Thanks!

Nico

P.s. Meanwhile the "topic" I have to choose for this is Mojave, because only three Apple apps are listed as available topics and I don't need help with iCal...
