There is no such thing as a Powerbook Pro. Apple changed the Mac names from Powerbook (no Pro in the name) to MacBook Pro as the name of the top of the line notebook computers in 2006. And some early notebooks in 2006 were just called Powerbook. The label under the screen will tell you what you have. Regardless, Mountain Lion won't work on a MacBook Pro older than 2007. That's what Pondini was getting at. Had nothing to do with the oldest MacBook Pro. The oldest MacBook Pro can't run Lion, let alone Mountain Lion. Read this tip on the minimum requirements for Lion:
and Mountain Lion:
There are three differing things going on with the ML support or lack off
Mac Pro 1.1 and 2.1 models have efi32 and can't boot the kernel in 64bit bit mode.
ML is fully 64bit and these two machines are stuck even through they can run 64bit processes and programmes.
Regrettably the onboard rom chip is soldered on and not upgradible, however there "may" be a way to simulate EFI64 out there on the web.
Its somewhat difficult too follow and I would never recommend it on any system critical system !
Earlier Itel Core Duo are similarly 32bit and unsupported.
Sorry no work around for these that i know of.
Macboook Air and the Macbook Core 2 Duo models with integrated GMA graphics do not meet the required Open CL/GL standards for ML support.
Again there are work rounds for these machines on the web changing certain kext files and disabling system check files. Once again not recommended on system critical systems !
As is the way with Apple and there products they are at one of the points in time and in the Hardware/Software system development cycles - That is Total movement over to true 64bit and High Def graphic based computing.
Unlike the "darkside" they do not baulk at the idea if ending legacy support if necessary.
when I updated to 8.1 one of the first updates was a ROm update for EFI64
BTW: I updated toMountain Lion.
Forced Time Machine to Update after I connected another external Drive and used CCCloner to created a bootable Clone of the Drive. the unmounted both. Took upstairs to my Cable modem and hooked up to Ethernet.
Took 45 minutes. So far I've only had to play with the fonts and repair permission. The only time I get thermal run away is when using Time machine to restore some fonts.
Office works Fine Acrobat works fine.
Even allowing computer to sleep (close lid and reopen) to a few more seconds to wake. But did.
I wnet into System Preserences and turn off items I was uninterested in I even unchecked the new item when you shut down to remember windows.
I did get three updates. One of which was a new EFI ROM upgrade. Even tat went without a hitch.
Another thing I have noticed That applies to all applications that uses a Templates setup If you open a document (Word, Excel, PowerPoint, Pages Numbers, keynote and thers that use a template setup) It opens the document, opens theplatewindow and opens a new Document at the same time.
Apple guidelines say That unless already created Document is opened the application is to open a new document or templates window. So this new thing is going against Apple's on guideline by opening original Document, Templates, and Blank document. Its mays though application open much slow and cause spinning Beach ball. once evrything is open then lighning fast.
If i wanted to purchase a new computer every other year i would have stuck with the old windows computers. Switched to apple for it's ability to use over years( not just a few). So what i buy a new computer now and in a year or 2 they do the same thing.
Hey new opperating system 10.10 little bitty kitty time to buy a new computer because all you loyal customers none of the old computers can handle it and we want more money. Sincerly with love Apple.
No thanx apple going to see what the Microsoft Surface has to offer.
Now I'm really glad tht I never upgraded to Lion, now knowing that Apple will not support my Black 2008 13" MacBook (2.4 Ghz Intel Core Duo 2) with future updates. MacBook4,1. I can still run programs that I used on my old 12" 2004 PowerBook G4. Apple used to be about backwards compatibility and now your computer will be obsolete when it's 4 years old. Insanity!!! Still rocking Snow Leopard 10.6.8.
Well, they're messing around with us now.
I used to be a die hard MacHead, but now, I'm starting to really hate the latest hardware AND software. So much now is uncompatable and full of glitches (the Mac minis are absoutely HORRIBLE! Every day, I have dozens of issues with them in our classroom!).
I can't help but believe that profit is out-weighing quality--something that I had once loved and marveled about Apple seems to be no more.
C'est la vie... Caveat emptor
It helps. We once faithful, loyal MacHeads are sending a message that we are not going to be the loyal, trusting life-long customers that we once thought we would be.
Apple, are you paying attention?
We're MAD AS **** AND NOT GOING TO BUY ANYTHING (once it was enthusiastically, EVERTHING) ANY MORE!
Gee, let's maybe rethink our (long-term?) bussiness ethos.
