In the not-too-distant future we'll have a better version of the Mac OSX BOINC client and GUI, that will do this for you. For the time being, you can try just starting the client in the background. On the command line (assuming you are using the bash shell):

nohup ./boinc_4.19_powerpc-apple-darwin > boinc.out 2> boinc.err &

This will start the job in the background. You can now exit the terminal window and log out, and the job will continue to run. It will run until you reboot the machine (or BOINC crashes).

If you use csh I think the right syntax is:

nohup ./boinc_4.19_powerpc-apple-darwin >& boinc.out &
