Cannot access Recovery Mode on Mac OS X I am using a model A1278 Mac and I need to reinstall the OS on it, or reset it. I am attempting to open the recovery mode by using the Cmd + R method but that did not work, I then attempted to use the Option method. That too did not work.

I am out of options and very, very inexperienced in the Mac OS, thus any assistance would be greatly appreciated.

Unsure on the OS X version I am using.

Thanks
The original A1278 MacBook Pro unibody was shipped with Mac OS X 10.5.5 (Leopard).

You may find some useful information in this thread.  The MacBook you have was shipped with a DVD that contained the installation and recovery files.  Whether or not you have access to this DVD, you will have to purchase OS X 10.6 Snow Leopard from Apple in order to upgrade to the latest supported OS which is 10.10 Yosemite.

Apple Support:


  Upgrading from OS X Leopard If you’re running Leopard and would like
  to upgrade to OS X Yosemite, first you’ll need to upgrade to OS X Snow
  Leopard. You can purchase OS X Snow Leopard here.


While Yosemite is a free upgrade Snow Leopard still carries a $19.99 USD price tag.  See Apple's Upgrade Support page for details.

Depending on your investment, the price may be worth considering.
