brendankoch Posted December 7, 2005 Share Posted December 7, 2005 Can someone please tell me how to edit my com.apple.boot.plist file so that I can change the resolution to 1280x1024? I get permission errors even when using sudo. Link to comment Share on other sites More sharing options...
macgirl Posted December 7, 2005 Share Posted December 7, 2005 If you boot in Single User mode you are root so you can type nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist edit whatever you want the type Control-X to save and exit. If you booted in GUI run Terminal and type sudo su type your password type the command same command line as in single user mode. Link to comment Share on other sites More sharing options...

If you booted in GUI run Terminal and type sudo su type your password type the command same command line as in single user mode. Much more simpler way to do this is to browse with Finder to /Library/Preferences/SystemConfiguration/com.apple.Boot.plist and just drag damn' file to your desktop. After that edit your file (the desktop one) and save it. To finish the job you drag the desktop version in the same folder where the old one was ... /Library/Preferences/SystemConfiguration/ and it should appear some dialog window....press the Authenticate button and type your password when it's asked for. Good job ... all done! By the way ... did you changed your root password? To do so you open Terminal and type sudo passwd root. Then you type your password and after that type your chosen root password (twice) Now it should repeat first part and it should work. Link to comment Share on other sites More sharing options...
wesley Posted December 17, 2005 Share Posted December 17, 2005 Why would you want to drag it to the desktop to edit? Just edit the original one. Use a text editor like Smultron (yes, there's an Intel compiled version). When you try to save it, you'll get authentication popup and you just enter the password to save it correctly. Even simpler.

If this also don't work then maybe it's not possible with your Nvidia card in VESA mode. Link to comment Share on other sites More sharing options...

macgirl Posted January 10, 2006 Share Posted January 10, 2006 Open Treminal from the Utilities Folder, then run this: sudo pico /Library/Preferences/SystemConfiguration/com.apple.Boot.plist the system ask for your password, then add it after the Kernel Flags "Graphics Mode"="1280×1024×32" I don't know why it is not working with Graphics Mode 1280×1024×32 Just a hint, diconnect the TV connector before boot if it is connected of course.

TB205GTI Posted February 12, 2006 Share Posted February 12, 2006 I have some sort of the same problem.. I use -s to get single user mode, and I use emacs to edit the Boot file, but I get "read only". Ok I'll just chmod it to a+w, but then it get the following message: Read-Only file system.. what to do? Link to comment Share on other sites More sharing options...
Poni Kamu Posted February 23, 2006 Share Posted February 23, 2006 How can I make an other partition default. And can I make this bootloader run automatically (without F8) and wait a few minutes to choose if i want to run an other OS??? Link to comment Share on other sites More sharing options...
oZen Posted February 23, 2006 Share Posted February 23, 2006 You can try this: <key>Kernel Flags</key> <string>rd=diskXsY</string> to boot on another partition, but it didn't work for me (probably because of NTFS, perhaps with FAT32 it'll work who knows...) And with this you'll have the timer: <key>Timeout</key> <string>8</string> 8 seconds here... (As you can see in the file, <key>Timeout</key> and <key>Kernel Flags</key> could already be wrote, don't make twice...) Link to comment Share on other sites More sharing options...

lwilliams1950 Posted March 21, 2006 Share Posted March 21, 2006 I was editing my com.apple.boot.plist file and saved it back and now when I boot it immediately says "missing boot.plist file".

sensimeon Posted August 22, 2007 Share Posted August 22, 2007 got it working with macgirls method thanks a lot! *didn't get it to work on jas 10.4.8 but yes on uphuck 10.4.9 v1.3* Is it possible to use 1680x1050? Link to comment Share on other sites More sharing options...
hei_zen Posted September 9, 2007 Share Posted September 9, 2007 Works nearly fine. "Graphics Mode"="1680x1050x32" in my com.apple.Boot.plist results in 1400x1050 (unchangable). A real progress in contrast to the formerly unchangable 1024x768. But does anyone know why it works only with 1400px and not with 1680? Edit: ?video at Startup shows that there are only 4:3 ratio resolutions like 1024x768, 1280x1024 etc. available. Is there any trick to get 16:10 ratio resolutions like 1280x800 enabled?
