Quick-fire questions
How do I reorder items in the menu bar?
> Although Big Sur’s new Dock & Menu Bar pane gives most controls over the menu bar, it can’t control the order of items displayed there. You can rearrange most of them by holding the ç key and dragging them into order, but note that the Control Centre and clock are fixed.
Why don’t I have permission to open an app?
> This error message most often occurs when an app fails a signature check required by macOS. Occasionally this is because permissions aren’t set correctly or there’s a fault in its security or other settings. If it won’t open normally, contact the app’s developer and ask their advice.
