Overclock Your Macbook Pro: Melts Everything It Touches
ZDNet has come up with an application that will allow you to overclock your Macbook Pro or Apple Xserve (provided they’re Intel processors and running at least OS X 10.5). Initial tests suggest the overclocking will allow the lower end Macbook Pro to perform at least as well as the topend model but no guarantee the fans can hold up to the heat generated.
ZDNet uses three Mac Pros as test machines. One comes from the first Intel/Mac Pro generation (Mac Pro 1.1) with 65-nanometer processors and 1333-MHz front side bus. The others come from the third generation with 45-nanometer processors and 1600-MHz front side bus, as sold by Apple since January 2008 (Mac Pro 3.1). The first computer is equipped with two 2.66 GHz X5355 processors, and runs stable at 3.10 GHz, see figure 2. The other two have two 2.80 GHz E5462 processors. These can be overclocked up to 3.24 GHz and remain stable
Stable maybe, but the Macbook Pro already runs hot, even with the fans jacked up to 6000rpm it’s a hot little machine. I watched an Apple tech put a Macbook Pro into some kind of loop that tested the processors, running both cores up to 100%. Took it about 15 second to start glowing. Makes me wonder how this would affect the heat output as well.

Protecting Mac OS X From Malware
Ran across this Slashdot article referencing another article put together by a well known hacker (Dino Dai Zovi) that makes some suggestions for how the upcoming MAC OS X mini-update Snow Leopard could take to prevent future malware attacks. It’s an interesting read if for no other reason than to gain a bit of insight into what the exploits try and do.
MAC OS X Mini-Update: Snow Leopard
There’s a bunch of talk floating around about the upcoming MAC OS mini-update “Snow Leopard” (aka: OS X 10.6). While the screen shots disappear about as fast as they appear (no doubt Apple trying to keep up the suspense) a few of the more interesting details have emerged. It appears the update will include things like Safari 4.0’s “Save As Web Application” feature and Exchange integration with th Address Book. Another big egg drop is the fact the PowerPC world may be at an end. Rumor is, Apple will finally drop backwards compatibility for the PowerPC and only Intel CPUs will get to experience the awesomeness that will be OS X 10.6. Personally, I can’t wait.
