Matt and others:
Below are some preliminary testing steps I have done with Catalina on my AirBook. I removed all of the “programming” type software to get back to a more “pure” machine( removed: Arduino, Saleae Logic, LabRecon (which definitely crashes and burns under Catalina), Microchip MPLab, Simple IDE and BlocklyPropClient (Parallax)). There is almost nothing on this machine except Apple software (exception is Audio Hijack which allows me to increase the speaker output volume when watching Netflix video many of which have insufficient volume for my old ears to hear).
In all testing cases I removed the Joulescope app and any Joulescope folder (either in the Documents folder or one level up), and then restarted the machine. I was not able to locate any other files associated with Joulescope.
The following results were consistent several times and did not depend on the actual Joulescope being attached or not via USB. In all cases I never saw the “verifying software” message during install and never saw any Joulescope folder created.
AirBook is running Catalina 10.15.1 with all possible updates.
- Open and unlock Security & Privacy System pref.
- Open and drag Joulescope app to apps folder; then eject install disk.
- Open Joulescope app: always get the “cannot check it for malicious…”
- After clicking OK from that window, the Security window changes to this:
- After clicking Open Anyway, I get this window:
I then click Open. At this point no apps are open other than Finder.
Click on Joulescope app. It does open. I can the open and close it multiple times and get a Joulescope window.
I did not try recording any actual input signals. The Joulescope app does always recognize that the “device” is attached or not.
