Hey everyone big RA2/YR fan here. Unfortunately I have become a mac fan boy because of all the apple pro apps I have chosen to use.
The good news is, I have successfully gotten Mental Omega 3.3.0 to work flawlessly on my Mac. Without bootcamp.
What you Need:
1. Porting Kit https://portingkit.com/download
2. The Complete collection purchased on Origin.
Part 1: Follow the paul the tall instructions to get RA2/YR working in porting kit.
Part 2: Once you can confirm you have RA2/YR working through the Paul the tall method, download mental omega normally. Once you have done that, grab the necessary files from the RA2 folder inside of Porting kit
Click "more"on the RA2/YR on the porting kit page for the game and click Advanced tools - open C drive
Once the "c drive" is open in finder click "origin games", then click "Command and Conquer Red Alert II" you should find the 7 files you need to copy into your mental omega folder
BINKW32.DLL, BLOWFISH.DLL, GAMEMD.EXE, RA2.MIX, RA2MD.MIX, LANGAUGE.MIX, LANGMD.MIX
Once you have copied those files into the mental omega folder, head back to the porting kit page for RA2/YR, click more, advanced tools, Install patch or mod, once you're there, navigate to the "MentalOmegaClient.EXE" click on it, and that should work
there is a way to add Mental Omega to your origin so you can boot the game normally, but thats a whole separate tutorial.
I did get 3.0 working, but when I preform a software update for MO, the launcher loads, and I still hear the sounds of the menu, but the screen is just black and blank, any ideas?
