Mac Heads - Snow Leopard

[LabRat]

yo i need someone to help me identify in Snow Leopard where i can see if im running 32 or 64 bit. im having very awkward moments with system crashes in logic. i think i may be running at 64bit and would love to change that

[SolDios]

Correct me if im wrong, but I think theres only 2 versions of SL

Consumer

and

Server

give this a go?

go to the apple logo - about this mac - more info.

Click software in the left hand pane.

If '64-bit Kernel and Extensions' has no next to it, your in 32, if it says yes, your probably in 64 bit

And to tell if logic is running in 32-bit mode:

You can switch between 32-bit and 64-bit mode following these steps:

1. Quit Logic Pro or MainStage if it is running.

2. Navigate to the Logic Pro or MainStage application in the Applications folder.

3. Choose Get Info from the Finder File menu.

3. Disable the option to "Open in 32-bit mode" to open in 64-bit mode. Enable it to open in 32-bit mode

cheers bud. id rather work in 32bit mode to be honest lol

where abouts do i find the "64-bit Kernel and Extentions" part? opened up the "About This Mac" part and hit More Info but cant seem to find it :/

[LabRat]

actually, ive just realised my processor is an i7 with is only 64 bit but the sounds of that link... might have to change over logic to work in 64 bit then :/

[LabRat]

ok, done it all. +rep for you sir

i was having some major issues with Reaktor so hopefully this fixes it

[Mitch]

when you hit more info, click software on the left hand side, and the "64-bit Kernel and Extentions" will show up along with a bunch of other things, e.g.

Your most likely NOT in 64-bit mode though. That is how snow leopard was designed. If it isn't in 6 bit mode, don't try change it to be in 64-bit mode, because there is incompatibilities.

I don't have logic, so can't comment if it will run better in one mode over the other. But i guess you could try both, and see what works better for you.

[LabRat]

yeah it says im in 64-bit mode and i found out that my processor has a lot to do with that setting. i've changed everything to suit 64-bit but if there's a way of changing it i'd probably prefer that. only saying this because i ran the same software on my mbp which is 10.5 (Leopard)

[Mitch]

If its booting to 64 bit by default, you can boot into 32-bit mode on a once off basis by holding in keys "3" and "2" when the computer is turning on. If you want to change it on a permanent basis, check out this article:
