Will OS X 10.7 Lion run on my computer? All Apple computers with an Intel Core 2 Duo or later processor will run OS X 10.7 Lion. Will my software that I have installed on my Mac running OS X 10.6 run on OS X 10.7 Lion? All Apple computers ran on Power PC processors until January 10, 2006 when Apple introduced Intel-based machines. Software written to run natively on both types of processors are known as Universal Applications. Older software written only for Power PC machines has to be run in emulation on Intel-based machines. An application called Rosetta was written to run on Intel machines to bridge the gap. Most of the newer versions of your applications will work, older versions that required Rosetta to run are no longer compatible. RoaringApps has a very comprehensive app compatibility table to easily check if your applications will work: RoaringApps compatibility checker
