I did a fresh install of OS Monterey on the Imac and since then the Imac can connect to the MBA but the MBA can't connect to the Imac. I tweaked numerous settings on both computers, reinstalled OS Monterey on the MBA. As you can see from the screenshot, the MBA can see the Imac - it just won't connect. I've looked at the file-sharing settings, finder settings, etc... I'm confused. Any suggestions???
