As a workaround, can I edit the Isadora preferences file manually while the Isadora application is closed?

 I don't know how to edit the preferences file since it's binary and not plain text, but one workaround is:

Use the steps in this article to install both the newer version of Isadora, and an older version of Isadora that doesn't have this problem.Delete your Isadora Preferences (use the steps under "macOS" and "Windows Option 2" from this article to delete all of them.)Open an older version of Isadora that doesn't have the issue.Change the OSC port in that versionClose the older version of IsadoraOpen the newer version of IsadoraIt will create a new preferences file by copying the older preferences file, in theory taking on the OSC port you set in the old one.

NOTE: If you want to change the port again, you need to perform steps 2-7 above again.

Thanks for this insight. The 2 license approach is where I am leaning. Having a year on a second license allows work to take place for a longer period, after which I could reevaluate whether I still need the additional license for another year. 

I'm glad to hear that it's worth it to do the upgrade. It sure seems like there are significant things that make it all more flexible, versatile and easier to do a lot of things... especially audio. I look forward to working with it.

I appreciate your feedback.

Best,

I solved it for now

Hello Frank, I have 2 suggestions:
1, open Live Capture Settings menu and check that only channel 1 video input is active. If channel 2, 3 or 4 has a tick next to it, and Elgato is the default device for one of these channels, then it won't show up in the list for channel 1. (I lost my facetime camera for 6 months when I didn't realise this)
2, try adding the Elgato through a USB hub. I had trouble connecting to mine the other day when it was plugged directly into the mac.

I'm not seeing the exact same behavior as you, but something similar. I am able to close Isadora Settings, but I do see that on newer versions of macOS, this causes an eternal popup that can't be closed for me, so I'll log that.

Best wishes,

Woland
