Thanks for the advice

But the specific issue here is the stability issue for accessing an I-series NVR on a Mac and I can confirm to you from our testing that all the things you mention above do not work for the I-series NVRs, especially the Developer/user agent setting which is something we tried long before Hikvision started introducing a 'Plug-in free' solution and we tried to use Safari with the user agent set to IE and it made no difference (as
@macman says) because Hikvision then and still now do not have the software/plug-in to install on the MacOS that fully supports their camera/NVR software and so although now with the latest NVR & Camera firmware you can get a live view image and control camera/NVR settings, there are still lots of menus, settings, and buttons that are missing when viewed on a Mac through any browser.
