Running Mojave on my iMac, I use several SMB3 shares on my Synology NAS that need to stay mounted for periodic access, one is for Time Machine, one has my iTunes database, and one is used for backups (running Mojave on my iMac). Before installing Automounter, at least one of the mounts (but generally not all 3) would randomly become unresponsive after some period of sleep; it would still appear in Finder, but the folder would appear to be empty, and if an application tried to access it (Time Machine, iTunes, or Carbon Copy Cloner, depending on the share), the application would go into an unrecoverable hang (Mac would hang during attempted force quit and restart, requiring a hard reset). Disconnecting from the share (in Finder) would similarly hang. Appears to be a macOS problem with SMB shares. With Automounter, my shares stay mounted (or very quickly remount upon waking the Mac) regardless of how long the Mac and/or the drives on the NAS have been asleep. I've had no issues with my NAS shares since installing and configuring Automounter, thank you for this simple but useful App!
