Is Your Machine Good Enough for Snow Leopard K64?

Monday, August 31st, 2009

“K64″ is what Apple refers to as the 64-bit version of the kernel beginning with Snow Leopard. As an end user, you really should not worry about the bitness of the kernel.

A Note on Pathname Processing in HFSDebug

Monday, November 24th, 2008

A couple of weeks ago, I released HFSDebug 4. I’ve updated it to make HFSDebug’s pathname processing a little more sophisticated. Depending on how (and how seriously) you use HFSDebug, knowing the details could be useful.

That said, I have to say that the recent furor regarding the so called OSX.Macarena “virus” amounts to, well, bullshit. If anti-virus companies are pretending to “recognize the threat” and therefore attempting to [...]

For the Record…

Saturday, November 4th, 2006

After I published Understanding Apple’s Binary Protection in Mac OS X, eWeek published a story on Apple’s binary encryption: Apple Places Encrypted Binaries in Mac OS X Although there’s nothing excessively misleading or incorrect in the story, to me, some parts of the story sounded like I had a conversation with eWeek. I did not. [...]
