Is it possible to upgrade OS X 10.2 to OS 10.8? I really don’t think so but I need to make sure. If I can, how would I do that?

Any other options?

    No. You need to get a new mac to use 10.8.

    To update OS X software select apple symbol menu, click on Software Update… and follow directions. Repeat after required reboot until reports your up to date. May be 4 or 5 times. For MS Office for Mac updates go to download site and search for your Office version.

    OS X originally ran on PowerPC-based Macs. In 2006, the first Intel Macs had a specialized version of 10.4 “Tiger”. In 2007, 10.5 “Leopard” was the first to run on both PowerPC and Intel Macs with the use of Universal Binaries. 10.6 “Snow Leopard” was the first version of OS X to drop support for PowerPC Macs. Mac OS X 10.7 “Lion” was the first version of OS X to drop support for 32-bit Intel processors and run exclusively on 64-bit Intel CPUs.
    Macintosh systems that can be made to run up to and including Mac OS X 10.2 Jaguar, all G3-based Macs which can run up to and including Tiger, and sub-867 MHz G4 Macs can run Leopard by removing the restriction from the installation DVD or entering a command in the Mac’s Open Firmware interface to tell the Leopard Installer that it has a clock rate of 867 MHz or greater. Except for features requiring specific hardware (e.g. graphics acceleration, DVD writing), the operating system offers the same functionality on all supported hardware.

    PowerPC versions of Mac OS X prior to Leopard retain compatibility with older Mac OS applications by providing an emulation environment called Classic, which allows users to run Mac OS 9 as a process within Mac OS X, so that most older applications run as they would under the older operating system. Classic is not supported on Intel-based Macs or in Mac OS X v10.5 “Leopard”, but users still requiring Classic applications on Intel Macs can use the SheepShaver emulator to run Mac OS 9 on top of Leopard.

    I had a friend upgrade from 10.2 to 10.8 via 10.6 first, but he had a friend that a the cd for 10.6 so he didn’t have to pay for it. After doing the upgrade from 10.2 to 10.6 there was no problem upgrading to 10.8 and he has no problems with it since he upgraded.

    To update your OS X 10.2.8 Jaguar install, you will either have to buy OS X 10.3.x Panther or OS X 10.4.x Tiger. I won’t recommend Leopard because:

    – I have no idea which Mac your are using and the hardware might not be compatible with the latest OS X version Leopard

    – Leopard seems to have a few kinks to iron out still and if you only run older software, they might not get on too great with Leopard: quite a few software apps had to be updated for compatibility issues.

    Try eBay or an Apple reseller for Panther or Tiger, I doubt very much the Apple Store is still selling those versions of OS X. Just make sure you buy the full retail install disk (it should be a black CD or DVD depending). Another thing to make sure os if your Mac can read from DVDs: if it’s an older model, it might not be able to read them.

    Starting with OS X 10.4.x Tiger, the usual install disk kit as in DVD form and if a user needed the CD version, they had to make a special order at the Apple Store.

    As an aside, the newer the OS you will use, the more RAM you will need to add in your Mac if you still want to enjoy using it instead of seeing it slow down dramatically.

    Hope this helps.

    apple not provide facility to upgrade the OS but you can update files released by apple

      i mean to say you can update your os by turn on auto update which will resolve your security and performance issue if your os is genuine

  • Jan Fritsch

    No, you won’t be able. Any Mac running OS X prior to 10.4 is obviously using a PPC processor. Support for those was dropped back in 10.6.

    • Oron Joffe

      Excellent point!

    • justinpot

      This means the highest you could get to is 10.5, which might not even be worth doing depending on the specs of the Mac. What are the specs? (Click the Apple at top-left, then “About This Mac”)

    You’ll need to at least buy a copy of Snow Leopard and then Upgrade to Mountain Lion through the Mac App Store. The snow leopard detour needs to be done because 10.8 is only available on the Mac App Store, which was added to the latest update of Snow Leopard 10.6.8 (or something around there). I highly recommend not going through with that for multiple reasons – one being that you’ll have to dish out ~50 dollars total for those upgrades and the second being that if it was running 10.2, it’s highly unlikely that it’ll run 10.8 efficiently just because of the advances in hardware between those OSes.
