Descalzo Posted March 25, 2009 Share Posted March 25, 2009 I had heard rumors that Apple wasn't going to support the Core Duo like from the original Intel Mac Mini or the original MacBook Pro (which I have). Well I tested it and it works just fine. I don't notice any problems at all. Of course, I just got it running not even 15 minutes ago, so I haven't put it through the ringer, but it's working great.

vbetts Posted April 11, 2009 Share Posted April 11, 2009 So then that means that Snow leopard isn't completely 64-bit, since Core duo is a 32-bit cpu. Link to comment https://www.insanelymac.com/forum/topic/159052-core-duo/#findComment-1130025 Share on other sites More sharing options...
Embio Posted April 14, 2009 Share Posted April 14, 2009 or maybe... just maybe...... it's made up of universal binaries. just putting it out there.... <_< <_< <_< <_< <_< Link to comment https://www.insanelymac.com/forum/topic/159052-core-duo/#findComment-1132764 Share on other sites More sharing options...
vbetts Posted April 14, 2009 Share Posted April 14, 2009 That would make more sense if it is. Even more when I just read this post in the "Is leopard a real 64bit OS?" topic. AFAIK Leopard kernel boots up standardly in 32-bit mode.It enables EM64T as a kind of extension (if possible with CPU...). Snow Leopard on the other hand has an mach_kernel Universal Binary which also contains x86_64... So from the boot up it is fully 64-bit...

Uptown_J Posted July 2, 2009 Share Posted July 2, 2009 I was curious about the Core Duos. Glad to see those aren't completely left in the dust. We have a tonne of them at my work. We may not move to Snow Leopard right away but you know how demanding designers can be :-) Link to comment https://www.insanelymac.com/forum/topic/159052-core-duo/#findComment-1190328 Share on other sites More sharing options...

We may not move to Snow Leopard right away but you know how demanding designers can be :-) I don't think core duos are 32bit only.

Embio Posted July 22, 2009 Share Posted July 22, 2009 your pentium dual core might be based on the C2D... there was a revision 6 months back. Still only has half the cache, mind.

Azimutz Posted July 22, 2009 Share Posted July 22, 2009 Well.. i think you guys are complicating a simple matter! If your processor can understand 64 bit instructions (has em64t/x86_64), it can run Snow in 64 bit mode. If not, it will run it in 32 bit. Simple I'm not a experienced computer user but, afaik all Intel processors newer than Pentium D (including) understand 64 bit instructions. That's all i can post about Snow on this site, as i'm not a Mac user...

Embio Posted July 23, 2009 Share Posted July 23, 2009 Core Duo and Core Solo are newer than the Pentium D and DO NOT understand 64bit instructions. Promise. Link to comment https://www.insanelymac.com/forum/topic/159052-core-duo/#findComment-1207737 Share on other sites More sharing options...
Azimutz Posted July 24, 2009 Share Posted July 24, 2009 yeah.. i believe you Embio. I know that there are exceptions, just don't know who they are.

JaE-V Posted July 25, 2009 Share Posted July 25, 2009 Just to clear up confusion here, all of the CD and C2D line of processors are full 64bit architectures. Run fine in -x32 and -x64 bit versions of snow. Working quite well too Link to comment https://www.insanelymac.com/forum/topic/159052-core-duo/#findComment-1208587 Share on other sites More sharing options...
rollcage Posted July 26, 2009 Share Posted July 26, 2009 I think maybe people are confusing the Core (Yonah) processors with the Core microarchitecture (Merom, Conroe, Woodcrest). Core Duos/solos are only 32 bit. I add my promise to Embio's. Link to comment https://www.insanelymac.com/forum/topic/159052-core-duo/#findComment-1209293 Share on other sites More sharing options...
realityiswhere Posted July 26, 2009 Share Posted July 26, 2009 http://processorfinder.intel.com/ Stop the bickering Core Duo's in that first "Select Processor" drop down list do not have the EM64T option, neither do Core Solo's, nor Core 2 Solo's. Very useful utility.. For more reference specifically on EM64T.. http://en.wikipedia.org/wiki/X86-64 Definitive proof.. Embio is correct.

Burpethead Posted August 22, 2009 Share Posted August 22, 2009 All you need to run Snow Leopard is an Intel (x86) Processor. Doesn't matter if it's old or new. Link to comment https://www.insanelymac.com/forum/topic/159052-core-duo/#findComment-1231998 Share on other sites More sharing options...
