Vakerorokero Posted September 19, 2009 Share Posted September 19, 2009 I'm having some problems with Snow Leopard booting in 64bit, and I need to boot in 32bit to test a tv capture card I got, any way I can do it? it's a pci card. Link to comment Share on other sites More sharing options...
The_Decryptor Veteran Posted September 19, 2009 Veteran Share Posted September 19, 2009 Undo the changes you did to get it booting in 64bit kernel mode (since it boots with a 32bit kernel by default) Or are you using an xserve or something?

the evn show Posted September 19, 2009 Share Posted September 19, 2009 Just undo whatever steps you took to make it boot in 64-bit mode. If you're holding 6 & 4 then reboot and don't touch anything. If you edited the com.apple.Boot.plist then go back and change the boot arguments line form x86-64 back to i386. if you edited nvram parameters just run the command again boot-args arch=i386 Link to comment Share on other sites More sharing options...
Vakerorokero Posted September 19, 2009 Author Share Posted September 19, 2009 (edited) I really don't know what I did to turn it on. and let it boot by itself and starts in 64 mode i got a MacBookPro4,1 model I already checkd com.apple.Boot.plist and here it is: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string></string> </dict> </plist> Edited September 19, 2009 by Vakerorokero Link to comment Share on other sites More sharing options...
DigitalE Posted September 19, 2009 Share Posted September 19, 2009 It should boot into 32-bit kernel mode if you hold the 3 & 2 keys on bootup. Link to comment Share on other sites More sharing options...
Vakerorokero Posted September 19, 2009 Author Share Posted September 19, 2009 any way I can make it default? how can I check the nvram parameters? Link to comment Share on other sites More sharing options...
the evn show Posted September 19, 2009 Share Posted September 19, 2009 any way I can make it default? how can I check the nvram parameters? "nvram -p" will print them, look for a boot-args line. "nvram -d boot-args" will remove boot arguments (you'll have to use sudo with this). If you can't remember changing anything to make it boot in 64-bit mode, what makes you think it is?

Vakerorokero Posted September 19, 2009 Author Share Posted September 19, 2009 it says it is in system profiler and some people witht eh same card are makng it work but say "it doesn't work in 64bits!"
