Safari browser (MacOS) goes blank during module updates - old problem...still on new freePBX 16 distro

It has been a problem for many years now. During module updates (involving several modules, large updates) the Safari browser (MacOS) looks like this after a while

Then I usually wait for some time…luckily I can check the LEDs (network, hdd activity) of the VM window on the original Linux machine

So I know, when I can reload the page. I am not sure, if this problem occurs with other browsers too. When I use Firefox in Linux Mint, on the machine where the VM is running, the problem does not occur.

EDIT: The system updates never go blank on Safari though…just the module updates…


Is there a way to see, if the module update has been completed? Terminal?
