    No. Lion requires a Core 2 Duo, Xeon Dual Core or better, i3, i5, or i7 CPU.

    I felt the same way when behind my many $$$$ dollar investment in my Dual Processor PowerMacG5 watched as the Intel CEO took the stage and Steve Jobs announced Apple was switching to Intel processors.



    Hey, it's better off you DON'T get Lion now, let all the others beta test and work out the bugs, several months from now you can pick the very newest machine with a stable OS X Lion.


    Blessing in disguise.


    round of points for all my fellows please.

  • Kappy Level 10 Level 10 (257,850 points)

    Hey! What do you think all those beta testers have doing all this time?


    Since when has there ever been a "stable" OS. Unless you accept the premise that they are all "stable" between this version and the next one.


    Beers for the points giver.

    Do you think this will when I get a new macbook


    Buy a new Macbook and then wipe the hard and install snow leopard on it and( since I alraedy have a bootable backup of snow leopard,, then install that backup on to the new mac then either do a dual boot scenierio or just install lion on top of snow leopard.



    When iOS 5  comes out for the iPhone it will probally not be worth since for the iCloud you need iOS 5 and Lion.

  • Kappy Level 10 Level 10 (257,850 points)

    I'm not sure what you are asking. However, I would not install a bootable backup from your current computer to a new computer because the OS version on the new computer may be a later vintage than on the old computer. This might be very problematical if the new computer is both new hardware and has Lion pre-installed.


    It's quite possible a dual boot would not be possible. But before you start transferring that bootable backup, you should see if it will even boot the new computer you get.


    Yes, Lion will be required for all of the iCloud features, but some of the iCloud features are already usable with Snow Leopard and the newest version of iTunes. There is nothing that indicates what the minimum required version of OS X will be for use with iOS5.

    Hmm, why would Apple include the hardware drivers on Lion for Core Duo machines they don't intend to support?


    If they don't, then one will have to do that themselves manually or else the hardware may not work properly and/or the fans run out of control, no Wifi, no webcam etc.


    This is a interesting development of course, unsupported hacking fun. Not to be done by amatuers without another machine to use and backing up of files etc.

    Perhaps because Apple doesn't want to officially support Core Duos but they know it will in fact run on one. This way they can play dumb and ignore the problems by simply saying "this version of the OS does not support your machine".

  • ReneLies Level 1 Level 1 (0 points)

    It's not about including drivers, it's about 32 bit vs 64 bit. You could run Lion on a core duo as long as they include binaries for the 32 bit architecture.


    Sadly I have to say that my macbook is a core duo, but I can understand the desision they made here. It's kinda the same as dropping support for the PowerPC (for which the G5 is actually 64 bit). I've heard that the hack described here isn't working with the just released version, but haven't verified that. Second, if you install Lion on your 32 bit mac, be sure to stop updating when they drop the 32 bit binaries!

    This is my Macbook and I seem to be able to run a depleted Lion operating system on it

    no full screen on some applications. no response to multi swipe actions, No Air Drop. and so on and so on. Also when it loaded it stalled with no real information and i had to go to reload Lion which then instigated further download of 6 minutes to load a slightly amended copy of Lion. thought i had lost all my info but it did all reappear

    It does have Launchpad and Mission Control but i seem to have lost my Isight camera in Photo booth and Skype. this has happened occasionaly before and a reboot brings it back for a while.


    Ah well Is it time to up grade the laptop?? Do i need a laptop?? Anyway ill keep this one for a bit and see how it goes at least some of the changes work.
