Mac OS X 10.6 Snow Leopard Server

[liupingguo]

fresh installed the Mac OS X 10.6 Snow Leopard Server, but I could not manage to make it run 32bit mode, therefore many programs can not run.

You can use either of these methods:

 

Method 1: Startup key combination (for current startup only)

 

If your server uses the 32-bit kernel by default, but supports the 64-bit kernel, you can start up using the 64-bit kernel by holding the 6 and 4 keys during startup.

If your server uses the 64-bit kernel by default, you can start up with the 32-bit kernel by holding the 3 and 2 keys during startup.

Your server will revert to the default kernel the next time you reboot it.

 

 

Method 2: On-disk setting (persistent)

 

To select the 64-bit kernel for the current startup disk, use the following command in Terminal:

 

sudo systemsetup -setkernelbootarchitecture x86_64

 

To select the 32-bit kernel for the current startup disk, use the following command in Terminal:

 

sudo systemsetup -setkernelbootarchitecture i386

 

Note: This setting is stored in the /Library/Preferences/SystemConfiguration/com.apple.Boot.plist file and will take effect every time you start up from this disk. If you start up from a different disk, the setting on that disk, or the hardware default, will take effect.

 

Additional Information

Keys held during startup (such as 3-2 or 6-4, method 1 above) will override the setting in com.apple.Boot.plist (method 2 above).

 

 

 

 

 

I tried the 2nd method but no success, anyone has idea?

[splonk]

Enter this in your com.apple.Boot.plist

 

<key>arch</key>

<string>i386</string>

 

 

For this to work, you need to ensure that your kexts are both 64bit and 32bit capable. There are some hacked kexts floating about that are solely 64bit.
