    You need to check your info about your Mac.

    PowerMacs can't run OS X 10,6.1.

    OS X 10.6.1 is Snow Leopard and OS X 10.6.x Snow Leopard only runs on newer 2006 or btter Macs that use Intel CPU chips.

    PowerPC CPU chips are made by Motorola and are not Intel CPUs. PowerPC Macs were discontinued in 2005.

    Actually the PowerPC CPU chip was developed and manufactured by a consortium that originally consisted of IBM, Motorola and Apple.

     

    See, http://en.wikipedia.org/wiki/AIM_alliance

     

    Today, IBM owns most of what was the technology behind the PowerPC chip and continues its manufacture for purposes other than Macintosh's, which abandoned that platform in 2006 to adopt the Intel CPU.

    Michael,

    Wikipedia aside,

    Are you really sure about this? One of Apple's tenets was to crush BIg Blue! Remember the 1984 ad?

    Why would Apple and IBM form an alliance when, clearly, Apple was out to directly compete on Big Blue's turf?

    The PowerPC CPU has always been, to my recollection refererred to as the Motorola PowerPC chip and not IBM PowerPC CPU. Also, after Apple switched to Intel processors Motorola continued to developed the PowerPC CPU architecture in the form of the Motorola Freescale line of CPUs.

    MichelPM,

     

    When I upgraded my old beige G3/300 with a G3/500 ZIF upgrade. the processor was clearly marked "IBM." In fact, the IMBs were preferred at the time over Moto because the IBMs hade all-copper internal structure where the Motos used some alunimum circuitry and ran a little hotter as a result.

     

    What ever public facade existed with the "Us v. Them" perception, business took a different path with the consortium that MichaelLAX linked.

    Come to think of it, the original G3 CPU in my beige 266 MHz PowerPC was a Motorola CPU, but when I started using G4 ZIF upgrades from Sonnet, these all had IBM stamped on their chip face.

    Don't know why I had forgotten this.

    Oh well.

    Steve Jobs was the force behind "them vs. us"

     

    He left Apple in 1985 (not to return until 1996)

     

    AIM was formed in 1991.

     

    If you have never seen it, watch the 3 episode PBS series "Triumph of the Nerds" narrated and based upon the book, Accidental Empires, by Robert X. Cringely and produced in 1996.  It clearly points out how Steve missed the mark by going after IBM and losing sight of Microsoft's challenge completely.

     

    (Episode 1: Apple invents the home computer market; Episode 2: Big Blue moves into the home market; and Episode 3: Microsoft Windows 95 is the game changer).

     

    AND, if you have not seen it yet and have Netflix streaming, watch Steve Jobs, The Lost Interview.  This is the complete 75 minute  interview that Cringely did with Jobs in 1996 for this series that was thought lost until the director of the series found a VHS copy just after Jobs' death. It can be watched either before or after Triumph.

     

    Cringely got Mark Cuban to put up the money to restore it to a theatrical release and home media in return for distribution rights (and as Cringely likes to say, enough money to guarantee that his kids could have a college education!).

     

    Remember, this interview is when Jobs was his most humble: he was pushed out of Apple ten years before, NeXT had failed as a hardware company and was faultering as a remade software company, Jobs had put most of his nest egg (from the sale of his Apple stock in 1985) into the operating expenses of Pixar and Toy Story had yet to be released.

     

    His look back is only exceeded by his look forward!

    Einstein is famously quoted as saying that he never memorized anything that he could look up: it took up too much valuable brain space!

     

    Unfortunately for me, I learned this quote way too late...
