Feb 17, 2016 5:11 AM in response to mcdanliby Lars-Iver Kruse,It's not recommended due to the fact, that there's no guarantee that older versions of MacOS X support the newer hardware of your system.
Have a look here:
Use the version of OS X that came with your Mac, or a compatible newer version - Apple Support
And here:
OS X versions and builds included with Mac computers - Apple Support

Feb 17, 2016 5:14 AM in response to mcdanliby KiltedTim,You can not run a version of OS X that was released prior to when the machine was released. You can find out what model you have by clicking on the in the menu bar and selecting About this Mac.

Feb 17, 2016 5:18 AM in response to mcdanliby Lars-Iver Kruse,Then click on the second link. With that information (mid 2012) and the type of your MacBook you'll see therein which version of OS X had been shipped with your device.

Feb 17, 2016 5:19 AM in response to mcdanliby KiltedTim,Then you can run any version of OS X that was released after the machine, and of course, the version it originally shipped with. Of course, you have to own a copy to install it, and it's no longer possible to purchase 10.9 or 10.10 if you did not do so before they were replaced and discontinued. Versions prior to 10.9 can be purchased directly from Apple.

Feb 17, 2016 5:22 AM in response to Lars-Iver Kruseby mcdanli,so then if it shipped with 10.7.4 I should be able to install 10.10.5 right? I have this copy available to install.
Again, thanks so much for all your help!!!

Feb 17, 2016 5:24 AM in response to mcdanliby keg55,i had a mid-2012 MBP Retina that came with OS X Lion (10.7.5). So, yours might be able to run that and above or OS X Mountain Lion (10.8.5) and above.
You could also restart into Internet Recovery (Command+Option+R) and see what OS X icon appears in the selection for Reinstall OS X. That should tell you what version of OS X shipped with the Mac. Then go from there as to what you can run on it.

My macbook pro came with El Capitan and I'd like to downgrade the OS. Is this possible?
thanks
You can only revert to a prior OS if you meet one of two conditions:
- You have a Time Machine backup of your system when you were using that operating system
- You previously installed the OS through the App Store and still have it listed in your purchases
If you don't meet either of those, you cannot downgrade your system. Rather than reverting, it would be smarter to get your issues with El Capitan resolved, because it's much faster and more stable than older operating systems.

Feb 17, 2016 5:39 AM in response to mcdanliby JimmyCMPIT,In addition to ownership of the OS or backup the Internet Recovery can be used to restore your mac to the OS that it shipped with and will use the final release version that was developed e.g. if your laptop shipped with 10.8.3 you will get 10.8.5 from recovery and only 10.8.5 will be the only result, you're not given an option to change this.
OS X: About OS X Recovery - Apple Support
Mid 2012 Macbook it possibly came with 10.7 or 10.8, however any OS after the final version of whatever your did come with would already need to be accessible to you in some form of media you presently own or you own in your App Store account, otherwise 10.11.3 is your only legal option.
