Hello , I need to run Pm headless , but mac will switch to 640 x 480 at boot if monitor it's not connected .
Pm do not work at 640x480 , I need the mac to start at 1024 x 768 .
Do you have any idea ?
the only thing I found till now it's this :
http://tvtool.info/go.htm?http://tvtool.info/english/dummy_e.htm
but I did not try it yet
Any other software solution ?
thanks

edit :
/Library/Preferences/SystemConfiguration/com.apple.Boot.plist
with :
<?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>
<key>Boot Graphics</key>
<string>Yes</string>
<key>Graphics Mode</key>
<string>1024x768x16</string>
</dict>
</plist>
where the reds it's addicion .
save the file on DESKTOP do not save the file in /Library/Preferences/SystemConfiguration/
( do that only if you know how to manage permissions )
If you don't save it on desktop . Same name . TXT editor will ask if you want to use txt exstention or plist . USE plist .
Once you save it . Drag the new file from Desktop to /Library/Preferences/SystemConfiguration/
Finder will tell you that the folder it's protect and will give you the option to autenticate your self as admin . use your admintration user and password .
BOOM ! that's it , you mac will boot start always with 1024x768 resolution .
any damage it's on your own risk

Update :
bad news , modify the file work but if there is not monitor the graphic card will not start and Pm will crash even if I see that the res goes to 1024 headless .
I don't know if Richard can fix this . But I don't think it's that important to spend time on it .
I'll try with the dummy monitor Plug and I'll report .

thanks emil.
i think in the past i have been able to change the resolution of headless imacs using remote desktop.
i cant remember what happens between restarts though.
