See the Technical Specifications for the full list of requirements. The latest supported software version is noted next to each model. You can install Mac OS X Lion on any of these Macs. Mac OS X Snow Leopard 10.6.6 or later or Mac OS X Lion 10.7 already installed.Now all we have are a bunch of I phone idiots walking out into the streets with their eyes glued to their phones.Mac OS X Lion 10.7 is available for older systems that are not compatible with the latest version of macOS. The New Yosemite and Lion and Montain Lion and Mavericks have done nothing except mess with older computer users and the programs that no longer work. At least they the old ones had caring about users in mind they tried to solve problems instead of creating them. Sometimes I wish they would fire all of the nerds that are now in place and hire back the old ones. Just another friggin Apple problem, that probably has no solution. I have also used the terminal program to try and access and unlock the drives I do not have the code at hand at this moment The previous date was 2/10 2015 before the message above This is the message that I get after running data Private Data 2/5/40 My Data Rescue Program says that the data was changed 2/5/40 "I say what the" I am fully aware of all of the ways to change permissions on the drives They all have a custom permission and when I try to change it to specify a user or admin as read and write they all go back to custom, and Yes I unlocked the get info before I tried. The two drives that have the lock on, are internal macpro drives this happened four days ago.

Same problem except that I am a 25 year Macintosh consultant and this has me stumped, I can use Data Rescue to see and recover all the files I need.
