Mac OS X 10.5.7 is Out on Software Update
Can't help but like this - a new version of Mac OS X is available on Software Update 10.5.7. From what I've heard, this looks to be one of the last updates to 10.5 before the release of Snow Leopard (10.6) later this year. There is a complete list of updates available, and a separate list of security fixes. Not bad.
Gotta take the time to update.
UPDATE: on the update, my machine hung and I had to power-cycle it. When I did that, everything resumed updating normally, and things worked themselves out. Also, after the update, I did another Software Update and got the latest Safari 4 Beta. Nice.
