hey guys,

i need to use 32 bit mode for my mixer when DJing however normally i want to be on 64 bit, so i just wondered as you hold down 3 and 2 on boot to get 32 bit, if you dont do it will it always be 64 bit ? or does it stay 32 until changed back in some way?

Just wanted to make sure im on always using 32 rather than only when i hold down 3 and 2 on boot.

Thanks for any help
 
You don't need to run the kernel in 64 bit to run 64 bit applications.
Even using the 32 bit kernel will allow you to run 64 bit applications, at least that is the way for Mac OS X 10.6 Snow Leopard on my C2D Macs and 64 bit applications.

its a fault with serato scratch live and the 2011 macbook pros, have to run it in 32 bit otherwise it dosent pick up the mixer. Its a known issue

guys im not asking if 64 bit apps run on 32 bit im asking about which the system defaults to when booted up

It is not a Serato issue, it is a driver issue. Rane's driver for is not 64-bit.

See here on how to boot into 32-bit kernel by default.

It defaults to 32 unless you force it to default to 64. You would know if you did that.

o ok, hopefully they update it. I dont want to default to 32 i want to default to 64 unless i specifically choose the 32 mode as i am using my laptop normally more than im using it on my mixer

it dosent as i had to tell it to boot 32 on start up to get the driver to work, hence indicating that it was in 64 before as was why it wasnt working

If there is an application that your mixer uses, go to the applications folder, right click on the app and select "Get Info".

Under the General tab, there should be a tick box to "open in 32 bit mode"

Check that box and you are away. No worrying about booting in 32 bit kernels.

Inferno,

I'm in the same boat as you. Using a TTM57SL with SSL and Ableton Live. Will not work when I'm booted in 64-bit, only 32bit. There is really no performance degradation.

Also, I will try the "run in 32-bit" mode later, but I think it's a driver issue not a software issue.

Waste of time; it is a driver issue, not an application issue. Bad advice.
