After many many many hours, both #Macbookpro now dual boots with a a “classic” OSX and a “modern” OSX.

MBP11 boots #Snow #MacOSXsnowleopard  and #macOS12.

MBP13 boots #macOSMavericks and macOS 12 (Monterey)

#OpencoreLegacyPatcher is f’n awesome.

So here are the Mac #shenanigans I am getting into:
1) Swap out 128gig ssd to 480gig in 2011 #MacBookPro
2) Restore backup of #MacOSXsnowleopard
3) Set up partition to dual boot, hopefully, #macOSMonterey

While also:
4) Do fresh install of #macOSMavericks to the 2013 MBP
5) partition drive to dual boot Monterey.

Then I will have some old and “newish” OS to play around with both MBP
