There is a bug report ticket called MacOS keyboard shortcut inconsistency, link: https://mcreator.net/tracker/issue/56209
This is a bug I believe, and it had always been like that since the very first Mcreator MacOS version.
The bug was patched and now I am able to use the cmd instead of ctrl (Exclusive to procedure editing. I'm not sure why, maybe it's another bug?)
But an error sound still plays when trying to use cmd+c to copy any procedure blocks or stacks, very strange.
Cmd+v does not play the error sound when used.
Can you fix it pls?
