Get Your Mac Ready For OS X Lion

On July 1st Apple released the golden master version (GMV) of Lion to developers - usually the last non-public version of OS X before the official release. If you want to update as soon as it is available, now is the time to check your hardware and perform a few system cleanups to ensure you'll be ready to download Lion on release day.Macworld runs through what you need to do to prepare. Most Macs from 2006 and newer should be able to install and run Lion without difficulty; the minimum hardware requirements are 2GB of RAM, 4GB of free hard drive space, and an Intel processor that is at least a Core 2 duo, i3, i5, i7 or Xeon. Furthermore you must have a recent update of Snow Leopard (OS 10.6.6 or better) as Lion will only available from the Mac App Store, which debuted in that version of Snow Leopard.

You don't necessarily want to skate by on the bare minimum of requirements, so it may be time to consider additional RAM, or if you might be better served with purchasing a new Mac with Lion preinstalled. If you're unhappy with the speed of your Mac running Snow Leopard, an upgrade may be in order.

After you've made sure the basic requirements are met it is a good idea to backup, run all Apple software updates, and check for updates for any third-party software you use. You should also disable FileVault if you use it as Lion includes a new approach to file encryption. See the Macworld full guide below for details.

    You should also be very carful to check if any software you depend on is Power PC code (note that PPC code was deprecated around 10 years ago). This is not supported on Lion, so if you have external hardware (in my case a midi controller) where the manufacturer (in this case Akai)is only providing PPC software, you can kiss that peripheral goodbye.

    I've been helping out a friend with some tech support and she's recently told me that she's still running OS X 10.4 (she doesn't care much for keeping up to date). When I sent her to go and buy snow leopard from an apple shop, she was told that they aren't selling them anymore due to lion coming out shortly.

    If lion is only being sold from within the app store (from what I've been told) how are people going to upgrade if they have older operating systems?

      You do realise that if she's running 10.4 that there is a high probability that she has a PowerPC and that it is incompatible with 10.6 & 10.7?

        Even the Core Duos aren't supported. So pretty much all of the Macs that ARE supported came with Leopard.

        Now before we get onto that, the "cheap" Snow Leopard copies are UPgrades. So you need 10.5 to update to it. NOT 10.4 I'd say any system that came with Tiger is on its last legs.

        The inability to upgrade from Leopard to Lion fulfils two purposes. Firstly, if they allow Leopard to upgrade, it will be unclear for PPC users and Intel users. Snowy upgrades at least cut off a lot of people who couldn't update anyway.

        Secondly and more importantly, Apple makes much more of its money from Hardware than OSs. If a customer hasn't upgraded from Leopard already, they're not financially important. They'll either delay buying anyway or they'll buy new hardware to keep up-to-date. Win-win for Apple.

      I just bought a copy of snow Leopard on saturday from a apple store in Sydney and they still had multiple copies of it on the shelf

    Does anyone know when Lion's going to come out on the Aussie Mac App Store? I've been checking frantically, the whole day today but still nothing.. It's already the 15th here.

    Then I read news that the UK store's going to be releasing Lion at 1am , UK time on the 14th.

    There is a lion in that picture.
