It has been at this spot for probably 45 Minutes. I started the install over an hour ago and it is stuck at the apple log and with a progress bar about 30% and a message below stating “installation is in progress: Calculating TIme Reaming. Locate the macOS combo update (you can find the downloads here) and Click Download. They are big files so it will take times to download and install. These update files are available on Apple websites. Depending on the macOS version you are trying to install, try using the macOS combo update. But at the same time, some new troubles might trouble you as well, such as like macOS Big Sur running slow, some apps get damaged or non-Apple Apps cannot be opened, Safari crashed, Mac gets overheated, or the Big Sur keeps logging you out etc.
After you have fixed the macOS Big Sur update stuck problem, you can enjoy the salient new features of Big Sur. You can do that in the Terminal with: sudo spctl -master-disable.
I suggest you deactivate Gatekeeper completely for the Installation of HotSpot Shield. I don't know if that specific note applies to Hotspot Shield, but i have seen similar Problems with other VPN-related Software.
