    Very much reproducible. Duplicate of existing issue listed on 2021.2.0 that is supposedly going to be fixed in 2021.2.2, but is still very active and do you have any Mac developers on your team at all?

    This is very much reproducible, it's not necessarily about moving a transform of an object but, more about general text input and interaction with the editor's inspector, assets, and hierarchy views.

    Overall interaction with the editor's fields are delayed by up to 2 seconds or don't update at all until there is another user interaction.

    Unity Version: 2021.2.1f1 (Apple Silicone)
    macOS: 12.01
    Computer: MacBook Pro (2021) m1 max, 32GB RAM

    Very disappointed to see this marked as not reproducible. I am easily able to reproduce the problem in the versions of Unity listed on the ticket.

    What should I do to fix the problem on my side? Is there a new version of Unity that no longer has this problem? Is there a forum post that addresses this?

    As of now, looking at Unity 2021.2.1f1 the issue still exists and makes the editor unusable on macOS.

    Whenever I attempt to type a number info a field in the inspector the editor appears to not update until another key is pressed, or something is clicked. This causes the last digit to not display until another interaction happens.

    Because of this, Editor is no longer usable on Mac. Should be of critical priority.

    I hope this is getting prioritised as it is crippling.

    I'm also experiencing this consistently, making the editor fairly unusable.
    Seen in both 2021.2 and 2022.1

    Can confirm, this is so annoying.. has something to do with the throttling setting. Tho deactivating that (No throttling) doesn't seem to work
