MacBook 0S X version 10.6.8 wont update!

Check that you can run mavericks:

Check via Software Update whether any further updates are required, particularly to iTunes (you will need the latest version in order to synch with mobile devices).

You should now see the App Store icon in iTunes, and you now need to set up your account:

You can now upgrade to Mavericks OS 10.9 for free IF you have one of the following Macs, with not less than 2GB of RAM, and at least 8GB of available space on your hard drive:

iMac (Mid-2007 or later)

MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)

MacBook Pro (13-inch, Mid-2009 or later), (15-inch, Mid/Late 2007 or later), (17-inch, Late 2007 or later)

MacBook Air (Late 2008 or later)

Mac Mini (Early 2009 or later)

Mac Pro (Early 2008 or later)

Xserve (Early 2009)

If you cannot run Mavericks you can purchase the code to use to download Lion from the App Store (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard):

or Mountain Lion:

Please supply the computer hardware configuration information as it relates to the ability of the build year model number and specifications; as these are needed to know what you have. There are limits in the hardware on what Mac OS X versions can be used, as some machines are considered 'vintage' and unable to run a system many years newer than the hardware.

So if you can visit the Mac App Store, the App Store, and the iTunes Store, within Mac OS X 10.6.8 in the MacBook, do you have an Apple ID? This is required to upgrade an OS X & also upgrade Mac Apps.

•OS X Mavericks: System Requirements

Find out if your computer can run Mavericks 10.9.2.

If it can, it also could run Mountain Lion OS X 10.8.5

Also an older computer that ran OK in Snow Leopard or earlier

may balk at Mavericks, but do OK in Mt Lion, or Lion 10.7.5.

But it may need more chip RAM installed for a later OS X.

If you can identify your MacBook, that helps to know what it can use

& what the update or upgrade potential is, to advance to newer OS X.

In some cases, the best bet in an older Mac is to stay with 10.6.8.

Good luck & happy computing! 🙂

As stedman & frederic1943 mentioned in your earlier thread : a 2007 macbook could only go as far as OS X 10.7 Lion, not Mavericks or Mountain Lion.

I'd echo K Shaffer's advice above, and stick with 10.6.8 unless you've a very good reason not to.
