Can't enable Flythrough mode on Mac

Hello... I'm unable to navigate the scene view via flythrough mode on a mac. Here's what I've tried so far:

• Holding [option] + left mouse click and drag does nothing.
• Holding [option] alone does toggle the Hand tool icon from the hand to the eye, but the mouse doesn't do anything.
• If I right-click and hold on the mouse, I can use WASDEQ but no other feedback from the mouse.

According to the Flythrough section on Unity's documentation page, https://docs.unity3d.com/2019.4/Documentation/Manual/SceneViewNavigation.html, I'm pressing all the correct keys.

Any ideas to what I'm doing wrong?

I made sure that I'm on the scene view tab and I'm in Perspective mode.

Unity Version: 2019.4.10f1
Mac Version: Catalina 10.15.7

 

Just realized I can't do anything with my mouse. Left-click and drag doesn't work either.

 

I have the exact same problem, but with version 2020.2.0f1.

Edit: macOS Catalina 10.15.7

 

I ended up fixing the problem by restarting my mac.
