Same here, using a Mac ever since and also using it for Android development. Due to the underlying Unix core of OS X you just have to follow the steps as described for Linux. If it's just adb commands it's the same on every platform anyway.
well just use the various adb commands in Terminal :) Just type in "adb", press enter and you'll get a list of all possible commands. Assuming you've added the path to your sdk tools folder to your bash profile. Otherwise just drag & drop the adb binary from the tools folder onto your Terminal window, et voila.
The most used commands are probably push and pull where you can, well, push stuff to your phone or pull it to your computer.
So if you want to modify the boot.mp3 you would pull the original from the phone to your computer, modify it and push it back, overwriting the original file. In Terminal speak: ;)
Please note depending on the ROM you're using the paths may be different. To browse the device via Terminal type in "adb shell" and make a simple "ls" to list the directories, "cd" to change directories etc.
