    how to run mac headless ?

    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://tvt...sh/dummy_e.htm

    but I did not try it yet

    Any other software solution ?


    thanks

    one possible solution :

    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.
