Maybe you'll all say "D'oh!!!" to this. But I didn't know before I asked, so I'll risk the public opprobrium...
Thanks to Mauti's technical wizardry, I'm able to run IT on my old steampowered G4 laptop... I've been d/ling map mods via this site too, and occasionally frequenting the forums here and over at ghostrecon.net.
End of last week, I had a chat to migryder about his new much-praised "Pressure" mod, just on the off-chance it'd work on a Mac, somehow, somewhere.
He very kindly sent me the files, I d'ld another couple, and now I think I'm ready to rumble on "Pressure", "Knight Fork" and "Africa Burning". All seem OK on the Mac so far (well, the system can see them at least, so we're halfway there).
So, did other forum members know that *some* mission mods at least seem like they're cross-platform?
Thanks to all - love the GR community...
