MacOS User Startup Issue
Open up the "Finder" app and search for MASQ.
Menu-click on the MASQ app icon and select "Show Package Contents"
Navigate through the Contents Folder, then MacOS folder and you will see the MASQ app executable
Run the MASQ exec file - it may prompt you with a terminal window opening showing trace event logs.
The MASQ app should open normally, with a small terminal window open (you can minimize this without any issue of app closing.)
