I'll have a look for the forums and a Mac video mag that say we're out of luck. Would naturally like to think you're right Martin!

Yes - this has been posted in several mac forums. Apple, if they so choose, can provide an upgrade to the firmware that will allow the Core Duo based Mac Pros to run in 64bit. Here's hoping..
I think you are confusing the 32-bit / 64-bit EFI question with CPU architecture. Some older Intel Macs do not have a 64-bit EFI and will not support the 64-bit kernel in SnowLeopard (which you can try out by pressing the keys '6' and '4' while booting).
As default, Snow Leopard runs a 32-bit kernel. There are however not many reasons to run a 64-bit kernel at this stage, since any user application may request and address a true 64-bit address space of its own.
the first macPros which came out had XEON 5100 processors - there has never been a macPro with a CoreDuo or Core2Duo, however the early macBook Pro, intel macMini and iMac had a CoreDuo

Just so I can understand, bottom line, do you think there will be a way where my iMac 2GHz Intel Core Duo will be able to run Snow Leopard even in 32-kernel mode, and will be able to afford a 64-bit application that 64-bit processing power?

I don't really understand what you mean. Your iMac 2GHz Intel Core Duo will run Snow Leopard today. It will not ever, no matter how hard you pray, be able to run 64-bit applications. Period.

Thanks for replying; I wasn't praying for anything, it's an iMac, not a €5000 Mac Pro, it's just that I wanted to ascertain its approximate value and got hopeful it would be worth a few more hundred € through Colin's 64-bit-upgrade talk; it seems now that was a misunderstanding on his part.
Hi Errikos
Sorry if I got your hopes up for nothing. I had just been referring to the early Mac Pros which I had read in a few forums would need an upgrade to run any 64bit apps. Thankfully Martin and Christian put things straight, well fortunately for me anyway.
Would your iMac be of no use to you as a Logic Node machine?
Colin
No problem Colin, I had given up on that machine anyway, but since you ask and others may also be interested, I had asked Christian (cm) that very question long time ago when I was in the market for a Mac Pro, and his reply was that I would be better off working on the one big machine exclusively rather than using the iMac as well, as a Logic node. Do you think differently? I also own a 2.16GHz Intel Core2Duo iMac if that would make a difference... Ideally I would like to put one or both into some musical use if that would mean better performance overall.
Christian knows his stuff Errikos and I've only ever had one Mac at a time, so I can't say what benefit you might get. There would certainly be no harm in trying.
I notice in the AU Manager that both Altiverb and Vienna Suite are available though I have no idea yet whether VS would still be available if used in VE Pro ( still to download it and purchase Snow L ). The minimum requirement for a node machine I believe is a single 1Ghz processor so your 2.16 could theoretically take a fair bit of load of your main macs cpu.
Hopefully CM or one of the team can give you the "Truth"!
