It’s time for the black roll-neck sweater-wearing, grande nonfat cappuccino-supping, snowboard-carrying, Apple Mac lovers amongst you to update your computers again.

Apple has released Mac OS X 10.5.5, which amongst other things fixes a variety of security holes that the Cupertino vendor says can result in “arbitrary code execution”. Ouch! So, by anybody’s standards it makes sense to roll this update out to your Apple computers as soon as possible.

Mac OS X 10.5.5

By the way, despite not owning black roll-neck sweater, not drinking coffee, and never having snowboarded (well, I did try to on the Nintendo Wii at my cat’s 10th birthday party on Saturday night, but I was rubbish), I do love Apple products. They do a lot of things very well.

One area where they could improve, however, is in their openness about security issues. I don’t seem to be the only person who feels that it would be a positive development if Apple were to “think differently” about how they currently approach talking about security. If you missed it, take the time to read a few interesting words that Mozilla’s security chief Window Snyder has had to say about Apple’s approach to security this week.

Oh no, I just realised, somewhere in this post I may have given an identity thief vital clues as to the full date of birth of my pet cat. Fortunately he doesn’t have too much cash in his err.. kitty. Groan.
