Things I have configured on my Mac that make it easier to do things:
Set the display to maximum resolution
Switch to bash.
Install brew
Set trackpad gestures to 4 fingers, and enable 3 finger drag (System Preferences > Accessiblity > Pointer Control > Trackpad Options)
Disable automatic graphics switching so that text doesn't look awful from using integrated graphics card. (not needed on M1)
Disable all the useless services (like convert to Chinese, open man page)
Mission Control > Group windows by app
Set the following so that gp alias works
git config --global push.default current
Renable the proxy icon, (the icon in the titlebars of windows): System Preferences > Accessiblity > Display > Show window title icons
Show services directly in context menu instead of Services submenu:
defaults write -g NSServicesMinimumItemCountForContextSubmenu -int 999
Disable the floating screenshot thumbnail (Cmd+Shift+5 > Options), put ~/Pictures/Screenshots as a stack+fan in the dock, sorted by Date Added.
Put screenshots in a directory, not the Desktop (or in Cmd+Shift+5 > Options)
defaults write com.apple.screencapture location ~/Pictures/Screenshots
Create ~/Stack folder and put it as a stack+fan in the dock sorted by Date Added (used for moving files between apps, eg for uploading, or just keeping track of files that relevant roughly now)
Add the following folders to the Finder sidebar: ~, DerivedData, Screenshots, Stack.
Show xcode build times (NOTE THIS CAN CAUSE ISSUES WITH SPM airbnb/lottie-ios#1379)
defaults write com.apple.dt.Xcode ShowBuildOperationDuration -bool YES
Set TextEdit to create plain text files
50% Alpha - makes an image 50% translucent, useful for pasting images on top of each other to compare them
Open commit on github - select a commit hash, click this then it will open that commit on github (only works on one repo I use all the time)
Switch branch - select a branch name, it checks it out in the last active terminal window
