FCP7 and Rosetta

[Chris Kenny]

[Marvin Holdman] “As they are saying Lion does not support Rosetta and FCP7 is a 32bit app, does anyone know how it’s going to run on Lion? I know they’ve said it will continue to work, just wondering how that’s going to happen.”

Rosetta is for running PPC apps on Intel Macs. Lion still runs 32-bit (Intel) apps just fine.

Is it safe to assume that all PPC apps will run in Lion?

OK, I just re-read my post. Meant to say 32 bit apps. Sorry.

No 32-bit apps will stop working on Lion because they’re 32-bit apps, but of course Lion, like every OS update, has the potential to break apps for other reasons.

Also, Lion may break some drivers because they’re 32-bit. A 64-bit kernel requires 64-bit drivers.

Although FCP 7 will apparently run under Lion, I’ve seen a couple of people mention that the Final Cut Studio 3 installer is PowerPC based – which means you can only install FCP 7 using Snow Leopard *after which* you upgrade to Lion. If you have a Mac with Lion pre-installed, then you won’t be able to install FCP 7 on it.

Can anyone confirm whether this is actually the case? Is the FCS3 installer PPC only?

Thanks!

Snow Leopard didn’t default to the 64 bit kernel except on certain machines. Will Lion be different? And wouldn’t the only dependency then be for 64 bit kernel extensions (kexts)?

Best,

Lion defaults to a 64-bit kernel, and actually drops support for 32-bit only hardware. (Of which there isn’t much in the Intel Mac world. Just the original Core-series processors. Core 2 and everything later supports 64-bit.)

And yes, the only new dependency this change directly creates is for 64-bit kernel extensions.

Not entirely true.
Lion will run on the Mac Pro 1,1 (2006) using a 32 bit kernel. That model Mac Pro cannot run a 64bit kernel.

But it is 64-bit hardware. Apple just hasn’t provided 64-bit drivers for some older gear.

Correct. The 2006 Mac pro has 64 bit processors and can run 64 bit apps. Just not the 64 bit kernel. this may be an issue with some drivers, if third parties stop support fit 32 bit . For instance, right now you cannot buy an Nvidia card with CUDA on a 2006 Mac Pro. It requires a machine with EFI64 firmware.
I just meant to clarify that lion still will include a 32 bit kernel, but will now by default load the 64 bit kernel on machines that can use it.
