Is there a version of HiP2P for my iMac?
As far as I know, there's no HiP2P version designed to work on Mac operating systems. Furthermore, it appears that the application has been discontinued, so there probably won't be any Mac version coming any time soon. However, if you have the installer saved, you could try setting up a Windows emulator such as Boot Camp or Winebottler on your Mac, then installing the application through that emulator.
HiP2P is alive and well as of today 07-27-2022. Here's the link for the MAC version: https://cctvdesk.com/download-file/HIP2P_For_Mac-0.0.18-BETA.zip
