How can I upgrade from 10.6.8 to 10.8.0?

I recommend you open the App Store and upgrade to Yosemite.

Backup first.

You can buy OS X 10.8 on the Apple Store: http://store.apple.com/us/product/D6377Z/A/os-x-mountain-lion

Make sure your Mac supports it before buying the CD.

You will have to purchase Osx Mountain Lion (10.8.x) if you really want it.

http://store.apple.com/us/product/D6377Z/A/os-x-mountain-lion

You'll get a code for the Mac App Store, and you can download it from there afterward.

Alternatively, and if the editing software you wish to use is supported in Yosemite, and your Mac also supports it, the Update to Yosemite (10.10.x) is free in the Mac App Store directly.

So far neither I nor the users I support have had one problem with Yosemite. So far it has been rock solid.

If you post more details on exactly which MBP you are running including the RAM and free disk space, we can tell you if it will.

The link above specifies the requirements for Mountain Lion.

On your Mac, go to Apple Menu -> About This Mac, and compare your specs with the requirements.

  System RequirementsTo install Mountain Lion, you need one of these Macs:

  iMac (Mid 2007 or newer)

  • MacBook (Late 2008 Aluminum, or Early 2009 or newer)
  • MacBook Pro (Mid/Late 2007 or newer)
  • MacBook Air (Late 2008 or newer)
  • Mac mini (Early 2009 or newer)
  • Mac Pro (Early 2008 or newer)

Your Mac needs:

  • OS X v10.6.8 or OS X Lion already installed
  • 2 GB or more of memory
  • 8 GB or more of available space

  
  

For What its worth, I haven;t had any issues with Yosemite on a 2011 Mac Mini and a 2007 iMac. Both run very smoothly for what they do.

I have a MacBook Pro purchased in 2010, says 4GB of memory listed in hardware overview.

In that case you should be fine for both Mountain Lion and Yosemite.

If you do decide to go to Yosemite, a RAM upgrade will be helpful. Your MacBook Pro depending on exact model may be able to go up to 16GB. At the very least 8GB.
