Hey guys,

Before I even ask, though I should, if Mountain Lion is worth it... can I even get it on my Macbook with Leopard? I never upgraded to Snow Leopard, or Lion because I was afraid my programs and such would not work with new OS.

Any thoughts you can give me?

You might want to give us information about your computer's specs and the apps that you use frequently...

Get us some specs on your machine.
Also know that ML is App Store only, so you'll have to install at least Snow Leopard.

Yes, it can run ML. Apple - OS*X Mountain Lion - Read the technical specifications.
General Requirements
  • OS X v10.6.8 or later
  • 2GB of memory
  • 8GB of available space
  • Some features require an Apple ID; terms apply.
  • Some features require a compatible Internet service provider; fees may apply.
Supported Models
  • iMac (Mid 2007 or newer)
  • MacBook (Late 2008 Aluminum, or Early 2009 or newer)
  • MacBook Pro (Mid/Late 2007 or newer)
  • Xserve (Early 2009)
  • MacBook Air (Late 2008 or newer)
  • Mac mini (Early 2009 or newer)
  • Mac Pro (Early 2008 or newer)
I would not recommend CleanMyMac, based on the number of complaints that have been posted in this forum and elsewhere. As an example: CleanMyMac cleaned too much. While you may not have experienced problems yet, enough people have that it's wise to avoid it, especially since there are free alternatives that have better reputations, such as Onyx.

Thanks GGJ, I have not had any issues but good to know, I will look into Onyx.
So you think I can upgrade with little issue? If so, if I have issues, and I back up my Leopard on TM, can I reboot with TM in case my apps do not work with ML?

I just want to make sure before I buy this upgrade, and find out A) none of my apps work and B) my Time Machine works too even though it was backed up on Leopard.

It states I have to have Lion or Snow Leopard to upgrade. ???
