We have a new MAC MINI 2019\2020 and old model (2018 ) running with ESXi 6.7U3 and noticed on new mac-mini VMs ( MAC\Windows\Linux) having issues connecting the network and downloading the files. The only difference is the network card which is a different model.

We have tried enabling the jumbo frame on the VMs and it started working and able to download the files but couldn’t find out the exact cause for the issue because from the hypervisor or having the MAC-OS we don’t have any issue.

Still investigating the issue and workaround is to enable the jumbo frame on the VMs.
