Please see the attached screenshot...
It looks like you're potentially running Catalina on your Mac, which is not yet supported by VideoScribe.
I'll convert this into a support ticket, so we can investigate further.
I`m having the same problems under Catalina on my mac.
There are some new settings in Catalina and we are still working on updating VideoScribe to make the install process smooth. In the meantime you can use this Apple guide to open VideoScribe - https://support.apple.com/en-gb/guide/mac-help/mh40617/10.15/mac/10.15
If you are still having issues after trying this please raise a support ticket so we can investigate further.
Thanks a lot, that was very helpful, it worked for me.
Thanks Barry. Workaround worked for me too.
