The “File” menu is blinking meaning that the shortcut is taken into account
When I open the File menu and then press cmd+w “Close Tab” blinks.
Same issue across all vaults, including sandbox.
I have no plugin, I reinstalled Obsidian, I deleted the .obsidian directory, no change.

Using macOS 13.2.1 and Obsidian 1.1.16, cmd+w works as expected and closes tabs over here.
My first thought was checking in Settings > Hotkeys that “Close current tab” is set to cmd+w, but you said it’s the same in the sandbox and with a new .obsidian directory.
I know it will take a few minutes, but if you have admin privileges on the mac, could you create a new test user in macOS and try Obsidian (test vault or sandbox is fine) in that account?
