Hi John,

there is a timeout setting in /etc/yaboot.conf where you can specify the time after which the default system boots. If you wish to make Mac OS X the default setting, you have to include »defaultos=macosx« in this file. You have to invoke »sudo ybin« to enable your changes after changing the file.

Hi John,

you have to edit the file /etc/yaboot.conf in an editor of your choice. As a beginner I would recommend nano.
Just type »sudo nano /etc/yaboot.conf« in the command line. Then you are in the editor. Search for the line timeout=... and correct to the timeframe you want to have. Default is 100. Then you can insert the line »defaultos=macosx« after the timeout line if you want to set OS X as the default system. Press ctrl+o to save and ctrl+x to quit the editor. Back on the command line, enter »sudo ybin« to activate your new configuration.
