Apple’s "point" releases — those seemingly-harmless updates you get automatically in Software Update — do sometimes break stuff. I tend to ignore the updates until I’ve had a chance to confirm they’re okay. Case in point: it looks like 10.5.2 can result in glitchy audio on laptops.

Native Instruments has an official statement out on the problem, but according to them, this issue can affect software from other vendors, as well:

User feedback and internal testing indicates that recent changes introduced by Apple in Mac OS X 10.5.2 can cause audio dropouts and similar problems on Macbook/Macbook Pro computers. This issue is not limited to NI software in particular, but applies to performance-criticial music software in general.
Therefore, Native Instruments currently cannot guarantee the proper operation of its products under Mac OS X 10.5.2. If possible, users should refrain from upgrading beyond Mac OS X 10.5.1 until further information about this issue becomes available.

Now, I will say this: I am frustrated with Apple’s OS upgrade approach — and I think on any OS, media support is the most vulnerable area.

Apple has unveiled its revised MacBook Pros today, with some subtle but significant improvements. I spoke to Apple a few minutes ago to get some of the details on what’s new.

The new MacBook Pro includes new, faster CPUs and the Santa Rosa Intel architecture refresh to the Core 2 Duo, delivering 2.2GHz and 2.4GHz brains and 4MB L2 cache. That should translate to a marginal but very measurable performance improvement, without having to spend a penny today over what you did yesterday. Santa Rosa also allows memory expansion to 4GB, huge news for anyone working extensively with sample libraries. There are also improved displays with LED backlighting and the addition of the NVIDIA GeForce 8600M GT GPU, basically a generation ahead the ATI X1600 in the original MBP (itself a very respectable card). We’ve got more on the visual side of the equation on Create Digital Motion, basically because I’m rapidly developing GPU lust.

What does this mean for music? Not the earth-shaking shift from G4 to Core Duo, but still some very good news. Think faster performance in audio apps, more memory for samples, and better displays and graphics. I know plenty of people on the fence on the MacBook Pro. Apple has the latest and greatest from Intel at roughly the same time as their PC-only competitors, so this should mean you can make an educated purchase decision today. And yeah, this might be my first choice even when I have to run Windows. (Come on, sometimes you need to make some beats in FL Studio or do your accounting.)
