I recently got the GOG version of Fallout 2, and I'm trying to get it to run with some mods on Mac.
I installed the restoration mod, megamod, and killap's unofficial patch using a VM - I just patched the Fallout folder in the c-drive contained within the wineskin. All of the patches seemed to work fine, but when I try to launch the game I get the 'Fallout 2 seems to be running in compatibility mode' error, and then the game closes.
I already disabled the compatibility check on the ddraw.ini, as well as on the fallout2.exe, so I'm a bit lost for options here. I also noticed that the game opens fine when I just open the exe contained within the wineksin from the VM, so it's clearly a mac-related issue.
I know the simple solution here is to just play on my windows VM, but I feel there has to be a way to make it work on my native OS. Is my method of modding the wineskin-contained directory incorrect? Anybody have any ideas?
I don't use a Mac but I did happen across this the other day, maybe it can help you:
Unfortunately by "help" I mean find out that the GOG version of Fallout2 for Mac will likely not work with fan-made patches. :(
Still, you could try re-posting your question on the NMA boards - if anyone does have a solution that would be the most likely place it'll crop up.
