I have this problem where I press the right click, and the mouse moves a few nanometer over the contextual-menu. When a release the right click, the system acts as if I just did a left click on the contextual-menu and do the action like "copy" or "change page"... This can lead to pretty annoying consequences.

The solution would be to stop the right click being treated as a left click when the mouse moves over the contextual-menu before the right click is released. I don't know if that's possible but honestly I doubt anybody use that feature in the first place. Another solution would be to make the contextual menu appear after the right click is released, instead of after the right click is pressed, if that is possible.

  • What kind of mouse are you using? Apple's Magic Mouse or something different?

  • Finally, I find someone having the same issue than me. I posted a question on superuser, I thought at first it was a Firefox issue, but it isn't because I can reproduce when using other contexts or applications: superuser.com/q/1546708/164524 Note that I can reproduce Note that I can also reproduce with the Magic Mouse but also with a Razer mouse. So it isn't related to the device neither.

This is expected behaviour & depends how long you hold your initial click for.

This is the same for any menu item on regular left click too. It is observed through the entire macOS.

  1. Short click & the menu will wait for another distinct click.
  2. Click & hold & it will trigger as soon as you let go.

If your mouse has a dodgy button, it may let go before you think you did, causing behaviour 2.

With behaviour 1, you can just take your time wandering around sub menus without having to click anything until you're completely ready. The menu will just wait for you.

As some appear to misinterpret this, here are two examples. The circle round the cursor is the click indicator, green is right, black is left…

short click - you can wander around the menu as you wish, even leave its bounds & return, it won't trigger until you click a second time, or click outside it to dismiss.

long click/click & hold - this will trigger as soon as you let go of the mouse button

  • It isn't a solution. The "bug" occurs because we "forget" about this "feature". In fact, we want to disable it, not modifying a behaviour.

  • Not knowing how to use it does not make it "a bug". This has been standard Mac toolbox behaviour since 10.0

  • Hi. Is it documented somewhere? That's what I wanted to know if it was a bug or a feature. So, nothing to modify this?

    Sorry, I have no idea if it's documented, or if it's changeable. It's just been that way for so long it's simply "how it works".

  • OK, I understand. :) That's a pity we can't change things like this.
