[Developers] Re: [Users] Mac users only: Mac/Intel

[Graham Bowyer]

Bert,

I am not a programmer, but my limited knowledge is that:

Code produced for PPC only, also runs on Intel Mac through an  
emulator/translator called Rosetta. This is entirely transparent to  
the average user, though experts report some loss of performance due  
to the extra layer.

Code built as 'Universal', runs natively on both PPC and Intel.  
Presumably, the application bundle contains code compiled for both  
PPC and Intel.

I have been doing some testing of OpendTect on an Intel mac. I can't  
see any difference between running the code on Intel or PPC.

Best regards,
Graham

Hi all,


Akio Sakai said that the Mac version we make for PowerPC also works on
Intel/Mac. Anyone with similar experiences?

If so, I guess we can stay on PowerPC for the build. I can also imagine
we move up to Mac/Intel, but for that it would be interesting to know
whether it also works reversely: will programs built on Mac/Intel work
on Mac/PowerPC?

If not, would we want to go to Mac/Intel anyway - in due time. We're not
going to support two separate builds (sorry), so the question is: what
would be 'in due time'?

Therefore: Mac users please react.
