Summary

What is the state-of-the-art way to setup a new Mac for software development? How do I keep my Mac software up-to-date? How do I get the most out of this non-trivial investment? If I need to setup a new Mac; how do I guarantee that I'll be as efficient on the new Mac as I was on the previous Mac?

About

The missing Mac Software Developer's Manual (MacBook Developer Setup Guide) Something that took me a really long time to get right as a software engineer is my personal development machine setup. There are several things that need to be in place in order to get this right:

1. backing-up installed applications (command-line applications & Native Mac Applications)
2. re-storing installed applications (command-line applications & Native Mac Applications)
3. backing-up system and application configuration
4. re-storing system and application configuration
5. Operating system ergonomics (keyboard setup, finder configuration, ...)

Remap "Caps Lock" to "Control"

Open Safari and navigate to "google.com"; then press Option + Command + c to open the developer console. You'll likely see some janky logs. To clear those out, you can press the Control + l key combination; however, the "control" key is in such an inconvenient place on the keyboard, especially for someone who uses the control key so often. It turns out, in MacOS it is easy to remap keys so they function as other keys. I rarely yell on the internet, so, I like to remap the "caps lock" key such that it acts as if it were the "control" key. This can be done on the command-line with the hidutil program. Now, going forward, when I'm in the developer console and I want to clear the logs, I can press the caps lock + l and it will function as if I had pressed control + l.

hidutil property --set '{"UserKeyMapping":[{"HIDKeyboardModifierMappingSrc":0x700000039,"HIDKeyboardModifierMappingDst":0x7000000E0}]}'

before pressing control + l

after pressing control + l

Reset "Caps Lock" back to "Caps Lock"

hidutil property --set '{ "UserKeyMapping": [] }'
