I recently bought a 16" MBP and since it comes with Catalina, I had to start over with all of the Apple emulators.
Here's a sit rep (as of December 7th):
- vMac:
OK
The custom variations service is no longer free (you have to donate $10 or more per year to have access to it). If you need a specific Catalina build, shoot me a PM and I'll compile it for you.
The only caveat is that I have to run it in low res mode (which only affects the title bar, not the actual screen). I don't know why it does that so I've contacted Paul C. Pratt about it. Will probably come up with a solution soon.
- Basilisk II:
OK
I forgot how picky Basilisk is with ROM files. On Catalina it simply wouldn't launch. After a few tries I got it working.
The GUI still hasn't been updated, and since the config file is hidden, it's not easy to change parameters. I created a dummy macOS app that opens the config file when you run it. It's
here if you want it.
Also, it seems to be
somewhat poorly optimized for modern machines, as my i9 is getting really hot while running it (90+ C). Works ok on my i7 10.9 MBP.
- Sheepshaver:
OK
Nothing to report
- GSplus:
OK
I had GSport on my previous Mac and GSplus is basically the same thing except it works on Catalina. The .txt config file didn't show up for me, only the hidden .gsp one. So, just like Basilisk I created a dummy app, available
here if you want it.
- Virtual II:
OK
Nothing to report
- ADT Pro:
OK for 2.0.2 or later?
Oddly enough 2.0.3 doesn't want to work on my machine. But 2.0.2 works fine if you manage to install Java SE 6, which unless you hack the installer, can't be installed on Catalina. Here's
how to hack it.
- PReVIOUS (NeXT):
OK
Nothing to report
- LisaEM:
Somehow OK
1.2.7 is still in its alpha phase. The power button doesn't work and the Lisa is REALLY SLOW. Looking forward to the final version, but it's looking promising.
- SaraOSX (Apple III):
NOPE
Current version dates back to 2008 and is a Carbon app, so
NOT compatible. Developper is still active so I might just contact them to see if they're interested in re-writing for 64 bit macOS. Source code is not available. MAME is apparently a good alternative, but I haven't been able to get it to work yet.
If you know of any other Apple-related emulator, let me know!
I wish PearPC had a Mac port! To emulate early MacOS machines, I have a
10.4.7 Server VM on VirtualBox. Rosetta is used to run PPC Apps, but it's not optimal.
