hello all, I have recently downloaded Garry's mod and it is just giving me a black screen with my mouse turning into a buffering wheel of death, im on my mac, I know I haven't been inpatient because I have waited about a hour (just watching tv while waiting ) on a blank screen, and was couldn't get out of it so I had to force quit and was given this link http://support.steampowered.com/cgi-bin/steampowered.cfg/php/enduser/std_adp.php?p_faqid=772, i have only ever played mobile games, online games and minecraft, i cant download steam on my PC for some reason so that doesn't work
