Switching between Light and Dark modes is also fairly straightforward on your Mac. To do so, follow the steps below:
Head to the Display panel on macOS Big Sur or newer, or System Preferences > General > Appearance on all older versions.
From here, you can switch to Light Mode.
To switch back, simply click on Dark once again.
You can also add a toggle for the Display panel to your menu bar and use that for quick switching between the two modes.
