Apple has released another bug-fix update to Mac OS X 10.5, a.k.a. “Leopard”. Version 10.5.3 has been in development for several months and fixes literally hundreds of “issues” in such areas as Airport, iCal, Mail, Time machine and others.
The update is available via Software Update in the Apple menu at the left end of the menu bar, or you can download the Combo Updaters that also include all previous Leopard updates and which have, in the past, proven to be somewhat more reliable in terms of avoiding potential problems. It’s probably also not a bad idea to launch Disk Utility (in the Utilities folder in Applications) and run both Verify Disk and Repair Permissions on your boot disk before applying the update.
I haven’t applied this update to any of machines yet, having just now discovered it was available, but I will do so soon and update this post with my results. Feel free to post your experiences in the comments section.
UPDATE 1: I’ve successfully installed the combo updater on a Dual G5 Tower and MacBook Pro. It is normal to see an extra Restart when the install has finished on PowerPC based Macs so don’t panic if that occurs.
