fuzy Posted June 30, 2010 Share Posted June 30, 2010 Hi, I have MAC OS X 10.6.3 Snow Leopard, and I'm using it with a 64bit processor. How do I set it to always boot as 32bit so I won't need to input the command "arch=i386" ? Thank you in advance.

MaLd0n Posted June 30, 2010 Share Posted June 30, 2010 copy the com.apple.boot.plist to your desktop Kernell flags you add arch=i386 replace reboot Link to comment https://www.insanelymac.com/forum/topic/223263-boot-in-32bit/#findComment-1501337 Share on other sites More sharing options...
fuzy Posted June 30, 2010 Author Share Posted June 30, 2010 I don't understand what i'm doing wrong here: <?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>arch=i386</string> <key>Boot Graphics</key> <string>Yes</string> <key>Quiet Boot</key> <string>No</string> <key>Timeout</key> <string>5</string> <key>arch</key> <string>i386</string> </dict> </plist> After modifying the file, if I don't input the "arch=i386" boot command it will boot as 64bits. Any suggestions? Link to comment https://www.insanelymac.com/forum/topic/223263-boot-in-32bit/#findComment-1501836 Share on other sites More sharing options...

Regards, Fuzy The com.apple.boot.plist may be in Macintosh HD/Extra/ or Macintosh HD/Library/Preferences/SystemConfiguration/ edit both of them. Copy the file to the desktop, edit in TextEdit and replace the original. Reboot.

fuzy Posted July 1, 2010 Author Share Posted July 1, 2010 Not working... any ideas? is there any place where the file is kept in cache? is the only reason i can think about... I couldn't find the com.apple.boot.plist in /Extra/ Link to comment https://www.insanelymac.com/forum/topic/223263-boot-in-32bit/#findComment-1502622 Share on other sites More sharing options...
MaLd0n Posted July 2, 2010 Share Posted July 2, 2010 chameleon looks first at the Extra if not find anything on Extra, the chameleon can read in the library/preferences/SystemConfiguration/com.apple.boot.plist already given in these two locations?

Gringo Vermelho Posted July 3, 2010 Share Posted July 3, 2010 If you don't know what he meant by that then don't worry about it. If you're curious, open Terminal and type Diskutil List at the prompt. If you see a hidden ~200 MB partition on your OS X drive then that's what he meant. Some of us install the bootloader and all the support files to that partition. If you didn't put anything there yourself then it's probably empty. But if you used an installer when installing the bootloader and blindly changed the install options without knowing what you were doing, then maybe your files are on that partition. Go here for more information (install instructions are for 10.5.x though): http://www.insanelymac.com/forum/index.php?showtopic=209712 Link to comment https://www.insanelymac.com/forum/topic/223263-boot-in-32bit/#findComment-1503723 Share on other sites More sharing options...
fuzy Posted July 3, 2010 Author Share Posted July 3, 2010 oh... I understand now... still... any idea why it is booting as 64bits with the arch=i386 boot flag ? it's not a big deal to input the arch=i386 but i'm just curious how to fix it, maybe i'm not the first person which is confronting with this problem and for sure i'm not the last so... how can we fix this ?

Gringo Vermelho Posted July 3, 2010 Share Posted July 3, 2010 Maybe you have Netkas' PC-EFI bootloader and not Chameleon. It uses -x32 instead of arch=i386 to boot in 32-bit mode.

No, because if I type "arch=i386" before booting, it will boot under the 32bit. But I want to make this automatically, so it will boot under 32bits without me inputing the arch=i386.
