Yardmaster will not open
Yardmaster does not open, or misbehaves as soon as it does.
The fix
When Yardmaster will not open at all
From the guide Yardmaster keeps doing things on its own: use Safe Mode
Start it in Safe Mode from outside the app. Quit Yardmaster completely first. If a copy is frozen, close it by force: on a Mac, open the Apple menu > Force Quit, pick Yardmaster and click Force Quit. On Windows, open Task Manager (Ctrl+Shift+Esc), pick Yardmaster and click End task.
Open Terminal and run:
open -a Yardmaster --args --safe-modeOpen the folder Yardmaster is installed in: right-click the Yardmaster shortcut on your desktop and choose Open file location. (From the Start menu, Open file location opens a folder of shortcuts instead; right-click Yardmaster there and choose Open file location again.) Look for the Yardmaster: Safe Mode shortcut. If it is not there, open Command Prompt in that folder and run:
Yardmaster.exe --safe-modeIf Yardmaster was already running normally, it does not open a second copy. On Windows, the running copy tells you it did not open in Safe Mode and offers Restart in Safe Mode. On a Mac, the running copy may simply come to the front; use Restart in Safe Mode in Settings > Diagnostics instead.
If the window opens but stays blank, see Yardmaster shows a blank window. To send the team the details, see Report a problem or ask for help.
