Hmmm, well I do have this world unknown on steam and it worked well last time I played it on my macbook – although it's gotten quite old so games don't run well on it as they used to – but I get it! Troubleshooting sounds troublesome (no pun intended haha), so I appreciate your honesty! I've been really interested in these two characters thus why I really wanted to play the game *-*
I'll look up one of your free games to see how well they run on this mac and decide after that :)
