Crontab Under Mac OS X 10.5 (Leopard)

November 8th, 2007 at 8:05 am (Mac OS X, sysadmin)

Beware – if you use crontab and are upgrading to Mac OS X 10.5 (Leopard), your existing crontab files will be DELETED by the upgrade!**(actually only moved & disabled – see comments) Back ‘em up first (yeah, I know you should always do a backup before upgrading, but this is really the only issue I found).

Also note that Leopard’s firewall seems to let everything through by default, even if that’s not what you previously had your firewall set to do.

Ejecting a Stuck CD or DVD from Mac Mini

November 1st, 2007 at 8:46 pm (Mac OS X)

If the disc is stuck in the drive but not mounted (i.e. doesn’t show up in the finder), and everything else has failed (eject button, F12, Cmd-E etc), and you want to eject the disk without having to reboot – for all you “uptime” junkies :-) – then try this in a terminal window:

drutil tray eject

and hit return. If that doesn’t work, try:

drutil list

This lists all removable drives you have connected.
Then type:

drutil tray eject n

where “n” is the number of the drive to be ejected.

Thanks to MacFixIt.com for this
