Phd2 Error- Instance 1 is already running

[dmajor]

Cant launch PHD2 - i get "error PHD2 instance 1 is already running. Use the -i INSTANCE_NUM command-line option to start a different instance"

On a Macbook  OS X10.13

Have killed the process via activity monitor, rebooted, and reinstalled PHD2.  Every time i launch i get this message.  No idea what command-line option is, and don't think i want to have multiple instances of PHD2 running!

Thanx for any help!

From the Terminal window, type or copy-and-paste:

ps -A|grep PHD2

If it's running, the process ID will be at the left end.  If nothing pops up, I have no idea what's going on.

To kill the process, type:

kill <process ID number>

To double-check if it's running again, just repeat.  If it is, you have a launch agent starting it repeatedly.  That's going to take a bit of effort to find.
