Do I need to look into the code or something related to app bundle may = be some settings in info.plist or any other pointer?=C2=A0

Have a look at the code arou= nd line 85 an onwards of pgAdmin4.cpp. It creates the shared memory interlo= ck (and log/address files) based on the current username and a hash of the = executable name/path. My suspicion is that the path hash (which is calculat= ed from argv[0] on line 72) is for some reason getting a different value ea= ch time when launched via the Finder or "open", thus the interloc= k is failing.

So I took a look at this, and it seems the code is just fine. What is hap= pening is that macOS only allows a single instance of an app to run at once= . Whilst that is what we want of course, macOS is causing the new instance = to exit before it has a change to open a new pgAdmin window. Using "op= en -n ..." or calling the embedded executable directly resolves that i= ssue.

So, there's another challenge to figure = out... :-(=C2=A0

=C2=A0 =C2=A0 OK. Will try to figure that out.=C2=A0

=C2=A0 =C2=A0 =C2=A0 =C2=A0 Afte= r googled I have tried following solution:=C2=A0
  1. Create a= shell script "launch.sh" and kept it in=C2=A0 "/Applications/pgAdmin\ 4.app/Contents/MacOS" folder. Th= at shell script will contain the command "open -n=C2=A0/Applications/pgAdmin\ 4.app/Contents/= MacOS/pgAdmin4".
