If you’re wondering whether your machine can be upgraded to run OS X 10.8 Mountain Lion, you can check the full list of supported models below.
To find out which model of mac you’ve got, hold down the option key on your keyboard and select

Check the ‘Model Identifier’ against this list:
Of course, just because your machine’s listed, it doesn’t mean it will necessary meet all the specifications, so be sure to check the tech specs too.
With the last seven days of July upon us, the suspense is just killing some people waiting for the release of Apple’s latest version of OS X, 10.8 Mountain Lion. While rumours abound for just about every conceivable day left being the ‘official’ release date (with the 25th being the most popular, it seems), the sensible are making sure they’re prepared. So here’s a few things to do both before and on the big day:
1. Check the tech specs
Check out the tech specs for Mountain Lion and the list of supported machines to make sure you can run it on your current system. If you are upgrading from Snow Leopard, you should also check out will my old apps work with Lion?.
2. Run Software Update
Make sure you have the latest version of everything by running
> Software Update
before you upgrade. This will help to cut down any compatibility problems when installing Mountain Lion.
3. Backup your current install
Without a doubt the biggest cause of trouble and frustration with every OS release is among users who didn’t backup their systems before trying to install the new one. Like Lion, Mountain Lion will be delivered as a download from the App Store, and while this method is certainly convenient, corrupted downloads are not uncommon. Moreover, even when the install proceeds as expected, you want to be able to get back to your previous system if you find things are not to your liking. An OS installation is like performing major surgery on your computer and the chances of complications are always a significant risk. As the old boy scout saying goes ‘Be Prepared’. Backup, backup, backup.
4. Remove everything from your Login Items.
For Lion users, that’s
> System Preferences…> Users & Groups | Login Items
If you’re upgrading from Snow Leopard 10.6.8, go to
> System Preferences…> Accounts | Login Items
There’s a couple of reasons for doing this, but mainly it’s to ensure that you can log in without difficulty. Login Items are one of the main causes of OS problems at the best of times, but with a major upgrade like this, you don’t want any incompatible software choking the system from booting up. See Steps 8 & 9 below about re-activating your Login Items after the installation.
5. Uninstall AV software & other utilities
If you have Sophos, VirusBarrier, iAntiVirus, F-Secure, or similar uninstall these prior to upgrading. After upgrading, if you must use them, look for updates. Uninstall MacKeeper, Little Snitch, LogMeIn or any other 3rd party utility that runs prior to user login.
6. Be prepared for slow download times
Apple’s servers will be hotter than a forest fire on release day, so you can expect download times to be pretty poor. At the very least, connect your computer to your router via ethernet cable rather than wifi – that’ll at least help push things along a bit faster at your end. If you can do it from the office or somewhere else that has a lot more bandwidth than the usual home connection, do so.
7. Save the installer
After the download completes the installer will run automatically. Do NOT click ‘Install’, but instead quit it. Then go to your Applications folder and copy the ‘Install OS X Mountain Lion .app’ and save it to your Downloads folder or somewhere else. Then you can run the installer in your Applications folder.
The reason for doing this is that when you install Mountain Lion the Install app in your Applications folder will self-delete. If the install shouldn’t work for some reason the first time round, you won’t have to go through the whole tiresome wait of a download from the App store again if you save a copy to your Downloads folder.
8. Update 3rd-party apps
Assuming Mountain Lion boots up just fine, the first thing you’re going to want to do (after having a nose around, of course!) is update your 3rd party apps. Start off by opening the App store to see if any that you’ve sourced from there have updates waiting for you. After that, start up all the main apps that you normally use and use their ‘Check for Updates’ option (usually in the Apps main menu), or contact the developers through their websites. If you use Parallels 7, you will need to update that before trying to run your virtual machines.
9. Test your Login Items apps
In particular, you’re going to want to test out the apps that you want to put back in your Login Items, before you put them back in there. Run each app and play around with the system for a couple of hours before deciding to put it back in your Login Items list. If you notice any weird behaviour with Finder, the Dock or Desktop backgrounds, problems with wifi or graphics, chances are one or more of your 3rd party apps needs updating to work with Mountain Lion. If there is no update yet, stop using that app till one becomes available or find an alternative. In general, it’s always best to keep Login Items down to a bare minimum. Running apps at login is a sure fire way to slow down boot up times.

As always, I’ll be here with tips on how to get the most out of OS X and how to solve some common problems. See you then!🙂
It’s been over 10 days since the jury went out to weigh up the evidence for and against Mac’s new operating system, 10.7 (OS X Lion). With Apple announcing a million downloads in the first 24 hours, there’s been no shortage of heated debate across the blogosphere and discussion boards (this thread runs to 60 pages and counting! Also see this witty and perceptive post about one user’s frustrations with the upgrade).
So it appears that some love it, others hate it, many are merely sanguine about the whole experience. A number of people are reporting trying it and reverting back to Snow Leopard with brow-mopping relief. My guess, though, is that the vast majority of Snow Leopard users are patiently waiting till a few updates have been released and all the early bugs ironed out.
It’s worth remembering the options: even if you buy Lion now to take advantage of the $30 opening price, you don’t have to install it now. You could buy it and leave the installer app in your Apps folder till the updates get released. Nor do you have to install it over the top of your existing installation. You could install Lion on an external disc instead, or move your Snow Leopard to an external disc and have Lion on your internal disc. Either of those options will allow you to play around with it and switch over fully when you’re truly ready. Don’t forget you can check out whether your existing software will work with Lion.
I have to say though, after ten days, 10.7 is starting to grow on me, and I think the external drive with Snow Leopard sitting on it is going to be gathering dust in a cupboard from now on. That’s not to say I’m thrilled with all that Lion has to offer. It’s a mixed bag, so sit back and let me read the court’s judgement in full. 🙂
The Good, …
— yes, I have unwillingly been converted. The four-finger screen swipe (left/right to change screen, up/down for Spaces and Expose, respectively) is addictive, and now I don’t think I could live without it. The truth is I could never get along with Spaces or Expose in Snow Leopard anyway, but Mission Control really does sort of force itself upon you. I do miss the App Switcher that is no longer available via the trackpad (Cmd-Tab still invokes it). There are free 3rd Party programs that you can get to add it back into the trackpad, but my experience is they are awkward at best.
— this is an app I use a lot and I love what they’ve done to it. Preview’s enhancements are one of the most undersold changes in all the talk about Lion. It’s always been ahead of Adobe Reader to my mind, but it did have shortcomings, particularly with adding and placing comments neatly and readably. The new Preview has tidied that up nicely, with the comment markers placeable with much finer precision and clear, neat lines indicating which comment each belongs to. The full screen feature also looks great and makes reading a pleasure.
— is growing on me. Switch it back to Classic view for a tidier interface, but there’s still lots of nice things about it. The animated display when you double-click to open a message is very neat (note: you won’t see the animation if you’ve got your IMAP account settings set to ‘Don’t keep copies of any messages’ in Mail Preferences | Advanced).
the Bad, …
Well, overall, the worst thing about Lion is that most of the good things are really cosmetic. There’s not a lot of new things you can do with Lion, and what there are, I don’t like much, particularly the triumvirate of data guardians otherwise known as
— Apple has gone to extraordinary lengths to ensure every keystroke, every page, every file you ever open is remembered somewhere (and often in multiple somewheres) on your internal drive and your backup drives. It’s worth noting that not all of these are places the average user can either find or remove. This is something that not everyone is thrilled about, and certainly it’s raised a few eyebrows among the security-conscious. If I were a Chinese blogger, I’m not sure I’d want to update to Lion (you think the Chinese don’t buy Macs? Oh,please!). Another thing worth noting about the Evil Trinity is that Apple has also made them extremely difficult to turn off. Resume, despite what you might be reading elsewhere, cannot be turned off by default (or at least no one’s found a way to do it yet).
However, with all these things, it’s not so much that you can’t beat them, but that you have to work around them. Adjusting your workflow to avoid Resume, Autosave and Versions is certainly possible, but something some may rightly begrudge paying $30 to have to do (in which case, that external backup of Snow Leopard I mentioned above is your friend!). I’ve already written about Resume, and I hope to post workarounds for Versions and Autosave in the near future (sign up for the RSS feed).
The only other ‘bad’ thing I have to say about 10.7 is LaunchPad. This is the iPad look-alike-finger-swiping app display (known as ‘springboard’ on the iPad). A complete waste of time: literally, it’ll take you forever to organise it, and even then it’s a very slow way to find anything but your most familiar apps. There have always been much faster and more efficient ways to get to both your most-oft used apps (the Dock) and those you only occasionally fire up (Finder).
…and the Ugly.
It’s not often that Apple do ugly, but its been universally acknowledged that the designs for iCal, Address Book and Photo Booth are a real eyesore. Fortunately, it’s easy to get rid of them with a bit of mucking about.
So should you upgrade or not? Well, why make it a black-and-white decision when you could have the best of both worlds? If you have a spare drive hanging around, whip it out, pay your $30 and take Lion for a test-drive. If it’s not for you right now, just put it away till the updates smooth it out and the time is right regarding compatibility. After all, if you’ve invested heavily in Apple products or have a lot of legacy material, then it’s probably only a matter of time before you give in and let the Lion tame you, too!
Thinking of upgrading but not so sure? There’s a lot of conflicting opinion out there about Apple’s latest Mac OS iteration. One of the key factors has got to be how much you rely on particular apps you currently use and whether they will still be compatible when you upgrade. Unlike other OS X upgrades, Lion certainly has backwards-compatibility issues (prompting some to wonder why they didn’t call this OS XI…). As has been well-publicized, Lion does not support PowerPC apps (though see my update here), and other issues concern the viability of third-party software. Here’s how to address your worries about compatibility for both issues:
If you want to know how many PowerPC apps you have on your current system and whether any of them include things you don’t want to live without, go to the Apple logo at the top right of your screen and click the first item in the menu, ‘About this Mac’.
Click the button ‘More info’ and select ‘Applications’ in the left hand column. In the right-hand panel, there is a list of all your apps and whether they are Intel or PowerPC (you may have to expand the window to see this column). The PowerPC apps will not run on Lion at all.
The world is full of truly good people, and if I was giving out awards for services to the Mac community, I’d definitely have the folks over at RoaringApps high on my list. Go check out their wiki and search for any program you’re worried about. They’ve got a list of every (yes, every!) piece of software that runs on Mac and an easy visual guide as to whether it’ll work on Lion or not. Thanks guys!
