It's unbelievable that Sony camera users can't update their camera firmware using a Mac running macOS 12 (Monterey). It's also unbelievable just how bad the firmware update process is.

I just spent an hour and a half trying to update the firmware in an A6400 using my MacBook Pro M1 Pro running macOS 12, which was released five months ago. In order even to get the updater to run, I had to follow and Byzantine procedure of different update files and folders and then change pre-boot security settings on my Mac. Only to discover at the end that Sony's firmware updaters don't even support macOS 12.

The update process for Mac, even if you're not running macOS 12, is just appalling. It's like something from the 1980s. I'd hazzard a guess that a majority of professional and likely also enthusiast photographers use Macs. It's so easy to design a firmware update system that a 10 year old could use - take a look at Nikon, Canon, Fujifilm or pretty much any other manufacturer for examples of how to do it.

PLEASE, please, please Sony, sort this out.
