Project Notes

MacOS Cheatsheet

A place to record some of my favourite MacOS tools, tips and tricks.

Digital Color Meter

Digital Color Meter is a utility provided in MacOS that can be used to easily ready the pixel color from anywhere on the screen. Great for quickly color matching.


How to retrieve windows that have moved ‘off-screen’

Occasionally I seem to be able to move a window entirely off-screen, especially when connecting an external monitor.

Hold the Option key down and choose “Arrange in Front” from the Window menu. It will then arrange all the windows of that application in a cascade from the top left of the screen.


Setting the Screencapture Location

In macOS Mojave and later, the screenshot location can be selected from the Screenshot app options menu.

In early versions, the location can be read and set using the defaults command:

$ defaults write location /Users/myname/Downloads/Screenshots
$ defaults read
	location = "/Users/myname/Downloads/Screenshots"

This page is a web-friendly rendering of my project notes shared in the LittleCodingKata GitHub repository.

LittleCodingKata is my collection of programming exercises, research and code toys broadly spanning things that relate to programming and software development (languages, frameworks and tools).

These range from the trivial to the complex and serious. Many are inspired by existing work and I'll note credits and references where applicable. The focus is quite scattered, as I variously work on things new and important in the moment, or go back to revisit things from the past.

This is primarily a personal collection for my own edification and learning, but anyone who stumbles by is welcome to borrow, steal or reference the work here. And if you spot errors or issues I'd really appreciate some feedback - create an issue, send me an email or even send a pull-request.
