I have both an Apple IIGS with a CFFA3k and an Apple //c+, now with a FloppyEMU. Unfortunately both of them are packed away So I've been using my 2014 MacBook Pro running emulators to run both regular Apple II and GS software. So I've been using Virtual II and Sweet 16. Since I upgraded to Catalina, and then Big Sur, I haven't been able to use Sweet 16. I've used KEGS, GSPort and GSPlus to run GS software but I really prefer Sweet 16.

I understand that Sheppy has had health problems, and some other things going on. So he hasn't been able to work on Sweet 16. So with that in mind I started looking online to find info about some how getting Sweet 16 running again. I found an article on Macworld uk talking about dual booting Macs. So I decided to give it a try.

I set up a second volume on my drive and downloaded Macos Mojave. Followed the instructions to make a bootable usb and Hooray! it worked. So I now have a version of Mojave running on my MacBook Pro and am able to run Sweet 16 again.

There can be issues running two versions of MacOS if you have any
drives in the older filesystem format.

You could use a virtualisation app (VMWare Fusion has a free version
for home use) to run the older MacOS inside the newer one. It does of
course use up more memory / resources running two MacOS versions at the
same time and I don't know if there's a noticable perfomance hit
running the Apple II emulation inside Mojave virtualisation inside Big
Sur.

I haven't checked out VMWare Fusion, guess I should. The only problem I have is that Mojave doesn't recognize the SSD, since it was set up with Big Sur when I upgraded to that, so it doesn't show up on the Mojave desktop, but if I open my external SSD I can get to the internal SSD that way. A little bit of rigamarole but it works.

He should open source his codes for others to take over if is health is degrading to keep his project alive.
