As soon as Mac OS X 10.2.1 was available via Software Update, I grabbed it. As much as I like Jaguar, the initial release had caused a few problems that I was anxious to fix.

Start with CDR burning. I burned a disc with my Sony CRX10U drive and tested it in Windows XP. Hooray! The Windows compatibility issue that had plagued Disc Burner in Jaguar seems to be fixed. The disc behaved well on both Macs and PCs.

Speaking of Windows, Virtual PC does run better with 10.2.1. I especially noticed improved scrolling in the Web browser — almost a natural experience on the TiBook 667 running VPC 5.0.2. Other behaviors were smoother also. It’s still not an environment I can spend too much time in, but for light Windows testing on the TiBook, VPC is now much more pleasant.

Other speed improvements on the TiBook include snappier Finder performance, better Entourage behavior, and much zippier Web page loading in IE.

For a real browsing treat in OS X, download Chimera 0.5. It’s a clean, responsive browser that you might enjoy bopping around the Net with. The tabbed interface is a joy on laptops.

I was experiencing some Rendezvous connection problems in Jaguar that I haven’t been able to duplicate in 10.2.1, and I ran through all the iApps without a hitch. Scrolling through large iPhoto libraries seemed better too.

So far, after a couple hours of use, 10.2.1 seems like a pleasant enhancement to Jaguar without any noticeable problems.

Let me know what your first impressions of Mac OS X 10.2.1 are.
