Last night Mac OS Catalina was released, we have noticed users can't successfully install the latest Omniscope on their machines.
We are working on a fix which will be available as soon as possible in the latest app daily build (https://visokio.com/evo/)
Please bear with us while we implement a fix, and be in touch if this is affecting your installation / systems.
N.B. once fixed this message a reply will be posted.
