Are you ready for OS X 10.8 Mountain Lion

This article originally appeared on the Tekserve Blog.

Can my computer run Mountain Lion?
You need to be running either Snow Leopard (10.6.8) or Lion (10.7 and later).
Here is a list of the computers that can run Mountain Lion.

  • 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)

To find out what kind of computer you have, click on the  logo in the upper left of your computer screen and select “About This Mac”. On OS X Lion, click on “More Info” at the bottom of the window. The model type will be listed on the next screen that appears.
An even easier way to tell (especially if you are running Snow Leopard), is to download the excellent Mactracker app to determine what Mac you have. It also has all kinds of useful information about every Mac model ever made.

Anything else my Mac needs to have?
Your Mac must have at least 2GB RAM and 8GB free space on the Hard Drive. Keep in mind those are minimum specifications, we usually recommend double that to make sure it runs optimally. Tekserve can max out your RAM and hard drive for a flat fee.

Should I plan on upgrading to Mountain Lion as soon as it comes out? Will my current operating system stop working?
You are by no means required to be the first one on the block with the new system. If you are on a mission critical computer (like one you use for work), it is probably a good idea to hold off for a few weeks or so, and definitely wait until your software is supported. Your old operating system will continue to work as before (although new apps will likely require the new system going forward).

How do I know if my apps will work on Mountain Lion?
All of Apple’s main apps, such as Safari, Mail, iTunes, and iPhoto, will be ready for Mountain Lion the day it launches. For third party software, we recommend you check out RoaringApps.com for an extensive list of real world experiences on the new system. Additionally, you will probably start to see a lot of updates to the apps you use starting to pop up over the next few weeks. Check their release notes for mentions of Mountain Lion capability being added.

Do I need an iCloud account to use Mountain Lion?
Strictly speaking no, you do not. However, iCloud plays a major role in Mountain Lion and it is very likely you will want one in order to use it to it’s full extent. If you don’t have one already, part of the setup process of Mountain Lion gives you the ability to create one.
What you will need is an Apple ID in order to purchase the update (if you have ever made a purchase from iTunes or the App store, you have one already).

Can I order Mountain Lion on a disc?
No. Mountain Lion will be available exclusively through the Mac App Store. It’s a big download (about 4GB) so you may want to plan on letting it download overnight. Don’t worry, you don’t need to be there the moment it is finished. Once the download is done, it will wait for you to wake up and continue the installation.

What if I don’t like Mountain Lion, can I go back to my old OS?
You can, although it is not simple. You would have to erase the computer, reinstall the old software, and migrate all of your data back. For this reason, we recommend making a bootable clone backup of your computer first. This way you can run the old system from the external drive if things don’t work out, and restoring it is much easier. Which leads to…

Should I backup my computer first?
ABSOLUTELY! You should always have a full backup of your computer at all times, but it is doubly important when you are upgrading an operating system. Take a look at our page on backup for some options. This is extremely important. Do not attempt to upgrade any operating system without backing up first.
