Hi Martin, sorry for the late reply. I am happy to say that this process worked perfectly, the only update that needed to be done after install was to give Eset full disk access. Is this method listed as the preffered way of installing on a Mac? The only way I could find before was the one listed in my previous note (which didn't work at all). It might be worth including this in the FAQ in the main site so that other people can take advantage of this install method. But many thanks for your assistance, I'm happy to close this now.
