Thanks very much for running the tests and collecting the videos.
Since VMware Tools appears cleared at this point, I will forward the internal problem report to the Fusion team for further investigation.
In the meantime, would you please provide answers to the following?
1. What version of Mac OS are you running on the Mac Book 2018?
2. Presumably the VDI disk was created/running on Virtual Box
- Do you recall what version of Virtual Box that was?
- Is there anti-malware application(s) on the Win 7 VM and if so what?
Thanks again for taking the time to provide details.
