logged into my old account ive had for almost 9 years, installed 1.6, source, hl, and hl2, etc... and when i click to PLAY it says it's not available on my current platform.
i have OSX 10.5.8 on my macbook pro but the forum and support search is not an adequate source of information to help me so far it seems..so i figured if one of you guys' got yours working you might be of some help.
i'd greatly appreciate it.
please pm or pm me for my steam name to chat.
