Mac OS X

My iMac's hard disk failed. It was under AppleCare warranty, so the service personnel replaced it. Previously, Mac OS 10.5 was on the old HDD. The new HDD came with 10.6 installed. Upgrade! Though, it's a bother because the system back up worked on 10.5, but does not fully work on 10.6. So, I'm having to replace some apps, and reinstall stuff, and reconfigure stuff.

In case you were wondering: Mac OS 10.6 is significantly faster than 10.5! I guess there was a bright side to my HDD failure.

I installed Collabora's gTimeLog application on Mac OS X (10.4 and 10.5). This tells you how.

This article is the first in a series which describes the creation of an elegant domain-specific language (DSL) for manipulating Mach-O files. Mach-O is the native format for executable binaries on Mac OS X. The DSL is embedded in Haskell.

This is Part 1 of the article. It introduces the Mach-O format, and explains the thought process involved in designing the DSL.

Using Google to search for information about Mac OS X is hit-and-miss. This is because there are so many ways to refer to Apple's operating system. Here's the code that I use to search with Google for information related to Mac OS X:

Mac OS X ships with a command line tool, 'leaks', which helps find memory leaked by a running application. This posting describes how to use 'leaks'.
