Nov 1, 2014 11:26 PM in response to Douglas Bashawby babowa,Did your machine come with Lion originally? If so, use your bootable backup clone to wipe your drive and reinstall 10.7 (or use internet recovery to wipe your drive and reinstall 10.7). If your machine came with Mavericks installed, there is no way as Macs are unable to boot from any OS version older than what they came with.

My Mid 2012 MacBook Pro came with Mavericks, I installed Mountain Lion on it. AFAIK, Lion should work, too, since the latest MBP (non-Retina) model was released in June 2012, and Mountain Lion didn't come out until July.

Nov 1, 2014 11:35 PM in response to Douglas Bashawby Douglas Bashaw,It is a retina MB Pro that came with Mavericks installed.

Nov 1, 2014 11:36 PM in response to stevejobsfan0123by babowa,Well, there is always that narrow window where they can possibly boot from either - in that case, it depends on the exact build number it came with. My mid 2012 MBP came with Lion. You must have purchased yours much later since Mavericks wasn't available until 2013 (as far as I remember), but, the chart shows that the mid 2012 came with either Lion, ML, or Mavericks.......

Nov 1, 2014 11:57 PM in response to babowaby Douglas Bashaw,I bought tha MB Pro used and according to the link, which you provided, it could have shipped with 10.7.4 or 10.8.

Nov 2, 2014 5:07 AM in response to Douglas Bashawby keg55,The easy way to know WHAT OS your MBP Retina shipped with is to restart into Internet Recovery (Command+Option+R). From the OS X Utilities Menu, see what OS logo shows up for the Reinstall OS X option.

Nov 2, 2014 8:31 AM in response to Douglas Bashawby babowa,Another way to find out is to call Apple (or stop at the nearest Genius Bar) and give them your serial number - they will be able to tell you with that.
FWIW, if you bought it used and it had Mavericks on it but the original OS was anything earlier than that, the seller didn't do you any favors as any OS (or app) purchased/downloaded from the app store is tied to the Apple ID used to obtain it forever - and it is not transferable. What that means is that unless he did a complete erase and reinstall the original OS (as required by the licensing agreement), you won't be able to update any apps and/or won't be able to reinstall as you'll be prompted for the seller's Apple ID/password.
So, let's figure out what it came with first; then you can try internet recovery (press Command + Option + R keys during boot up until you see it is connected to Apple's servers); in the Utilities screen, choose Disk Utility and erase your drive. When finished, back to the Utilities screen, choose reinstall OS X. While in Disk Utility, you should be able to re-partition - although I can't guarantee that'll work at that point because I've never tried it, but I don't see why it shouldn't. After you have it installed on one partition, install it again on the other partition. Once that's done, you can download/install Yosemite (or whatever) on one of the partitions using your own Apple ID.
Note: you must erase your entire drive in order to do any of the above.

Nov 2, 2014 10:04 AM in response to babowaby Douglas Bashaw,Thank you. I partitioned the drive and used time machine restore, from my old computer, to install 10.7.5 with Vectorworks 2008 working smoothly. The only problem now is I can't unlock, to change, date and time preferences.

Nov 2, 2014 11:01 AM in response to Douglas Bashawby babowa,Is it not accepting your password or what exactly is happening?
-
Nov 2, 2014 11:15 AM in response to babowaby Douglas Bashaw,I clicked on the little padlock and nothing, I then went to Keychain Access to unlock, it accepted my password, I was able to change the date and time, but 10 minutes later I had the same problem with energy saver and could not unlockk it.

Nov 2, 2014 1:18 PM in response to Douglas Bashawby babowa,My suspicion is that is has something to do with the old owner (but difficult to say); short of erasing the drive and starting over, try these two:
1. Go to Disk Utility (Applications > Utilities) and repair permissions. Restart when done.
2. In Finder, go to File Menu > Go > click on Option if necessary to show your Library folder. Navigate to Preferences folder and then move this to desktop:
com.apple.systempreferences.plist
Restart; open System Prefs and see if you can do it now. Check to make sure there is a new .plist in that folder - if yes, delete the old one. If not, move the old one back.
