My company has a Mac Mini that we use for iOS builds. Occasionally, one of us needs to log in to it via remote access (from a Windows PC) to update the build tools.
However, ever since updating the OS to the latest MacOS Mojave, most of the time we cannot log in remotely. On any VNC client (I use VNC Viewer but have tested this with UltraVNC as well), as soon as you establish a connection to the Mac, it just shows the login screen with the username and account picture, no password prompt or buttons of any kind, and a loading spinner that just spins forever:
I've found that I can "fix" this by physically accessing the machine and logging out of the account, but of course this is painful and impractical.
Is this just a mojave bug? Are there any ways to break out of this loop? I should mention that this did seem to work OK before the mojave update.
