The steam HTMLInterface however solves both cases, it has the licenses covered and since steam runs on mac, it's also able to actually run it's cef instance (for those who don't know, steam uses a slightly modified CEF branch of their own) There is still the possibility to just use a pre-CEF 2272 build for macs to run.īut it doesn't end there, CEF requires some tweaks and special licenses to allow patented codecs such as mp3 and x264. There are test builds of Source1 with 圆4, but they are, only tests. Source1 simply wasn't designed with 圆4 in mind, so more of a limitation then a requirement.
