Jul 16, 2012 2:37 PM in response to cmtrujiby Kappy,The current OS X version is Lion 10.7.4. Sometime this month Apple will release Mountain Lion 10.8.
What you need to do is:
Check that you meet the minimum requirements:
Lion System Requirements
- Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
- 2GB of memory
- OS X v10.6.6 or later (v10.6.8 recommended)
- 7GB of available space
- Some features require an Apple ID; terms apply.
Apple - OS X Mountain Lion - Read the technical specifications.
Purchase Snow Leopard DVD from Apple's Online Store - $29.00.
Update Snow Leopard to 10.6.8 using the Mac OS X 10.6.8 Update Combo v1.1 updater.
Access the App Store and sign in with your Apple ID.
Purchase and download either Lion - $30.00 or Mountatin Lion - $20.00.
Be sure you first backup your current system just in case. Before installing Snow Leopard erase your hard drive then install Snow Leopard from scratch.
