Now if only OS X would was allowed to work on my 3 year old system which is more than powerful enough for it based on hacked installs, and if only all the software wasn't updated so it won't work on the last OS. Thanks Apple!
Meanwhile I can install Windows 10 on a 10 year old system and play a 16 year old game just fine. Boo Microsoft for being horrible people that don't give away your amazing product for free and don't have a penguin or a fruit as a logo.
What three-year-old Mac doesn't support the latest version of OS X? OS X 10.10 "Yosemite" officially supports Macs dating as far back as 2007 (or 2008 or 2009, depending on the system), and I believe El Capitan will support the same.
