*******Fix for Apple Security Update bricking displays*******

[operator]

Hi Eddie, thanks for getting back to me.
I`m using Mac OS 10.14.6 (18G103)
I had previously uninstalled the app and prefs, but I did it again anyway. The problem continues.
FWIW, booting from a different partition on the same computer, EuCon works fine. This is using Mac OS 10.13.4 (17E199) and EuControl 2020.11.1.10, EuCon 4.7.4.10.
I tried uninstalling and installing EuControl 2020.11.1.10 on the Mac OS 10.14.6 system, but the problem continues.
I also tried removing the Euphonix folder from Library/Application support as I thought it might be the soft key files that were causing the hang, but the problem continues.
Is there any other location, that stores information that is not removed with the uninstall options, that EuCon might try to access when adding the Artist Control?
The hang report shows: Boot args: -no_compat_check. I don`t know if this information is useful?
