Hi all, Right, I managed to get OS 9 working on my UMBP after sever efforts and searching a hell of a lot on the google and that. I want to be able to play Simtower! OS 9 is working great, and it is a fully functional OS 9 as far as I am aware. The problem is, I can install anything on the OS and I can't work out why. I've never used OS9 before but it certainly isn't as simple as OSX! Any help would be appreciated. When trying to install/open anything I get this: Cheers for any suggestions. Oh, one last thing - I can't find the applications folder on OS 9. Am I being thick or isn't there one or what?! Thanks!
