peter I contacted Apple support regarding the zoom and spoke to a specialist, I explained I use to be able to zoom using Mac keyboard ctrl + scroll, now I can’t, it zoomed the whole screen and another two options are available which are totally inappropriate, he could not help me but has noted it down and will speak to OS designers to fix this.
Hopefully in next update we might be able to do this again , I have also pointed out the ridiculousness and limitation of their mouse setup , he noted all my suggestions, time will tell if things improve, to me it seems as though they are listening to computer nerds more than normal computer users because their feedback system is designed for the nerds.
