I wrote a shell script for Mac that will install CHDK (once you've downloaded the correct version!), no hex editing required. I did this before I noticed Owen had written one in Applescript, so I didn't even give his a shot. But if anyone likes doing things in Terminal, this will make it less tedious.
To get it, just run the following command in Terminal. I'd recommend you first cd into the same directory that the CHDK files you downloaded are in.
wget -qO install_chdk.sh
http://zwisslertech.com/projects/chdk/install_chdk.sh && chmod 755 install_chdk.sh
That will download it, put it in your current directory and fix the permissions. To run it, just type:
./install_chdk.sh
If you're in the same directory as the DISKBOOT.BIN this should be all you need to do, as it will try to automatically find your SD card device. But if you want to manually spec your SD device, or the path to your CHDK binaries, there are flags for that:
bash-3.2$ ./install_chdk.sh -c ~/s95_100e_v11
Finding SD device......found /dev/disk1
Would you like to proceed using device /dev/disk1 (reported size is 16.1 GB)? (y/n): y

To run CHDK, lock your SD card, insert in the camera and fire it up!
bash-3.2$
To get help, run it with -h:
bash-3.2$ ./install_chdk.sh -h
Usage: ./install_chdk.sh [-c path_to_CHDK_files] [-d SD_device_path] [-f] [-y]
-c defaults to the current directory (.)
-d defaults to autofind (with confirm)
-f overrides sanity checks on SD device
-y assumes yes to answer questions (non-interactive)
It is pretty conservative, does a lot of sanity checks and it asks you before writing anything, so it should be pretty safe. Hope this can be of help to some! (Also, I'm attaching a copy of the script to this post, so you can download from here instead of running wget).
