Not to get too excited, because we're months away from the eventual release of macOS 11 Big Sur, but comparing current macOS (10.15.5), the forthcoming point fix (10.15.6 [beta 2]), and the next release of macOS, it does look like this this becomes a non-issue. I am unable to replicate the issue under macOS 11 whereas I can reliably replicate the issue 100% of the time under Catalina, GA or beta.

Now, that's not to say that it still doesn't need to be resolved in Mojave and Catalina, but pointer behavior between the two OSes and the client might be a good place to start comparisons to narrow the issue.

Issue persists with 20w09a.

Any interaction with the java window prior to the game menu UI loading in completely triggers the need to double left-click on objects when using a mouse (MacBook Pro + Mac mini) or built-in touchpad (MacBook Pro) to select/interact with them. This is immediately apparent on the main menu, as selecting Singleplayer, Multiplayer, et al requires multiple clicks in this condition.

Not interacting with the window during the Mojang logo/loading screen and waiting for the music to begin playback allows the game to function as expected with single left-clicks from mouse or touchpad.

Only tested under macOS 10.15.3 (19D76) on both of my aforementioned machines; have not confirmed issue remains under macOS 10.5.4 (19E242d).

@unknown-

I can confirm that this is reproducible with both 20w07a and 20w08a as well. Tested on 2 machines: Late 2018 Mac mini with a non-retina display on macOS GA + Dev and 2019 16-inch MacBook Pro.

This behavior also occurs if the game client is set to start in fullscreen, when a particular build works in that manner (I have intermittently seen MC-6665 return under Catalina, but not reproducible enough to open a new bug).

The workaround provided by @unknown earlier does still work as described when launching the game in windowed mode and then activating fullscreen afterward.

Please let me know if I can provide any additional information.
