Zwift running very slowly

I started Zwift up today and it automatically downloaded a new version. However it runs very very very slowly and hogs a lot of CPU so it is unusable. Eventually I uninstalled the application and reinstalled. This had no effect.

I am am running this on a Mac Mini 2 CPU 8 GB Memory, and the OS version is Mac OS High Sierra version 10.13.3.

Please can you help me, I have been running Zwift perfectly successfully for over 18months.
