Hi @velvet_forcing_0a ,

There is a bug (defect) in AutoCAD 2024 for Mac.

If you have redefined standard shortcut with CUI command, you need to remove undefined shortcuts on Shortcuts tab of the CUI window:

 Select undefined (greyed out) shortcuts one by one and pick on "-" button to remove them from list. Save settings with OK button.

Now test Esc key.
