'Please note, on Mac we now require 10.6 or higher, and this release will not be available if you are on 10.5 or lower,' said Chrome team member Jason Kersey in a blog post yesterday about Chrome 22, which just entered testing on the developer channel. Apple's OS updates arrive more frequently these days - roughly annually - and Chrome comes even more frequently with a six-week update cycle. Leopard debuted in 2007 after a long gestation period. Just as Apple finished up OS X 10.8, aka Mountain Lion, Google said yesterday that its Web browser will stop supporting OS X 10.5, aka Leopard. Sundar Pichai, Google's senior vice president in charge of Chrome and Apps, said in June that Chrome is 'exceptionally profitable' for the company.
