Currently running older version

Additional context
Granted I know nothing about macOS development, I don't if there's technical reason why higher version macOS is required, but I have many applications which still actively updated without requiring newer macOS version namely, browsers firefox, edge, chrome, affinity suites, whatsapp deskttop, alfred, dash, obsidian, mpv, iina, amethyst, sublime, zed, reeder and many more which still running fine on Catalina/Big Sur.

So, I don't see why Vimr which a text editor needs newer macOS version.
