Has anyone found a nifty way of getting the Nightly Builds to update on a Mac without a manual download and install? I had vaguely hoped that after installing the Nightly Build I could go to Help/CheckforUpdates and (because it was a nightly build) it would go get the latest nightly build but sadly that was not to be!
Hi @farmer_giles. By default, Arduino IDE only offers updates when there is a newer stable release available. However, there is an advanced setting that can be changed to make it instead offer updates for newer nightly builds:
Press the Ctrl+Shift+P keyboard shortcut (Command+Shift+P for macOS users) to open the "Command Palette".
A menu will appear on the editor toolbar:
Select the "Preferences: Open Settings (UI)" command from the menu. ⓘ You can scroll down through the list of commands to find it or type the name in the field.
A "Preferences" tab will open in the Arduino IDE main panel.
Type arduino.ide.updateChannel in the "Search Settings" field of the "Preferences" tab.
Select "nightly" from the menu under the "Arduino › Ide: Update Channel" setting.
