Hi guys. Mac beginner here who's trying to play some really old games that I just to play as a kid. The moment I put the game in and try to start it this message pops up. I've tried reading about it on this forum but could not fully understand what I have to do. I'm currently using a macbook, 3 years old (if that's helpful to know) and the game is about 14-15 years old however compatible for mac. I looked up some system req for this game and again not sure if this will be helpful but here it is. Macintosh Power PC; 12 MB RAM, 20 MB på harddrive; System 7.1; 640 x 480 pixel color screen (thousands color); CD-ROM-player with double speed. Do I have to completely change my systems for my macbook in order to do this or how far will I need to go to open the games?
