Hi guys!
I recently changed my machine from a PC running windows7 to a MacBook Pro running snow leopard.
I've been using an emu 0202 to record stuff at home, capturing ideas...
It worked fine with windows, but on snow leopard, I just get crackles and distortion, sounds like really bad synch.
I messed with the few settings there are without success.
I googled the problem and there seems to be a fix, but I'm really new to the mac world and I don`t get what this guy meant:

E-mu USB sound cards are works in Snow Leopard!
But existing kext was compiled only for 32 bit system. If you want set up you E-MU USB sound card, you may write next kernel key when system is begin starting:
arch=x86
After use this key, system will be runed in 32 bit mode and all will be working!

I tried to search the internet on the topic, but I didn't get anywhere.
Has anybody an idea what the guy means by arch=x86.
I understand it has something to do with running the os in 32bit mode...

Thank you!
Best,
Stefan
 
You will need to force Snow Leopard to boot into 32-bit mode.

Two options.

Option (A) every time you boot, hold down the "3" and "2" keys.

Option (B) edit the file /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
Find this:
Code:
<key>Kernel Flags</key>
<string></string>

Change it to this:
Code:
<key>Kernel Flags</key>
<string>arch=x86</string>
 
That's really weird.
I always thought if that file was missing, your system wouldn't boot.

You could try manually creating the plist file in a text editor, adding the following:
Code:
<key>Kernel Flags</key>
<string>arch=x86</string>
Save it & throw it in the Library/Preferences/SystemConfiguration/ directory.

I think Snow Leopard comes with a plist editor...look in Applications/Utilities/ for something like a plist editor.
Not in front of the mac right now, so I'm not sure.


I really don't understand why or even how that file could be missing?

By default, Snow Leopard boots into 32-bit mode unless you hold down the '6' and '4' keys when booting or you modify the magic plist.

The Property List Editor is included with the Developer Tools.
