Caution on Upgrading to macOS High Sierra: Sony Firmware Updates

See my Nikon wish list and get Nikon D850 at B&H Photo.

According to Sony, you might not be able to update firmware for Sony cameras when running macOS HighSierra—see highlighted text in the image below .

Sony ought to be more clear, is it “may not” [sic] or “will not”, or something else.

Given Sony’s rootkit installer approach, it’s probably a security issue stopping it. Cameras should update firmware in camera, like Nikon and Canon do. Approaches that in essence require operating system kernel access are incredibly badly designed given the security risks.

At least Sony *does* properly secure its Sony camera firmware updates page with https, albeit with a certificate that is not the highest grade. That is necessary but not sufficient.
