Updates for February
There has been a slew of updates from Apple in the last week or so, most notably the 10.7.3 release of Lion. The reports coming in so far are favorable: lots of bugs fixed and problems repaired. I will be installing this myself this weekend (after making a clone backup so I can revert if need be) and I will write a further update if I have any trouble myself.
You can use Software Update, but some people are reporting problems with the Delta update (which is what Software Update uses). I strongly recommend going to Apple and visiting the Downloads section and getting the full-sized Combo Update. This update also boosts Safari to 5.1.3, and I hope this will fix the forced reloads and spinning-rainbow problems that have plagued 5.1 since its release.
I also want to see if I can successfully downgrade Safari to 5.0.5. Of all the browsers, Safari has been the most difficult to do this to, with Firefox being the easiest. Safari scatters pieces of itself all over your library and they ALL have to come out before a 5.0.5 install can succeed. If I do, I will report on the full details of how you can do it too.
There is a Security Update for Snow Leopard out as well. Due to the increasing frequency of malware apps attacking Macs these days, I recommend getting all of the updates they issue, after waiting the usual week before installing them that I recommend.
iTunes is now up to 10.5.3, which is needed for the latest iPod and iPhone 4S. I have been running it for a week now and have not noticed any changes at all. I'd say go ahead, but it isn't necessary unless you have the latest iDevice.
