It was pretty hard to find notes on this so I am posting in case it helps someone else.

Warhammer 40k Rogue Trader works perfectly with Mac M1 systems (with at least 16gig ram)


Notes:
-I haven't tested Galaxy install but I can if you want (let me know)

-the manual install works. (I am using Sonoma MacOS 14.1.2) and had to use preferences to tell MacOS to install it anyway as the file I received wasn't properly signed.  (I can document this if you need).

-the manual install asks for a directory and says it will run a script- its not really clear but whatever you choose it makes a folder and that's where the  game is installed.   The install process takes a good while and dont close anything while it's running. Later you can go to that directory and run the game.

-have had a few hours of play time.  No issues with anything and no crashes.

-the DLC was downloaded and installed separately. So far I can see at least the ship.

Let me know if people want me to test anything.
