1password 8.11.14 will not start on MacOS 15.7.1

It Flickers for a second but never starts.

PS: I have grepped ps for 1password, onepass and tinker. Nothing. I have already tried reinstalling, rebooting, completely uninstalling (getting rid of every remnant) then reinstalling.&nbsp;

Hello StokeMasterJack​! 👋
I'm sorry that 1Password isn't launching on your Mac. Are you running the app inside of a virtual machine by any chance?&nbsp;
Can you try the following to launch 1Password without hardware acceleration:&nbsp;

Right-click the 1Password icon in the menu bar and choose&nbsp;Quit. (If you see the icon.)
Open Terminal, which is in the Utilities folder of your Applications folder.
Type in: /Applications/1Password.app/Contents/MacOS/1Password --disable-gpu

Press Enter.&nbsp;

If this allows 1Password to open, then turn off hardware acceleration:&nbsp;

Click&nbsp;1Password&nbsp;in the menu bar and choose&nbsp;Settings.
Click&nbsp;Advanced, then turn off&nbsp;Use Hardware Acceleration.

If the Terminal command doesn't work then can you see if 1Password will open in Safe Mode: Start up your Mac in safe mode
-Dave
