Got it to work on Mac OS 10.15.4 (haven't tried the new 10.15.5 update yet) with the following approach:
Run the Sony A7R III firmware update. Hit the system update tool and go through the process. After it tells you to connect the camera on usb and it launches the actual sony camera firmware update tool. The Sony updater said I already had the latest firmware but I did not hit finish. I then switched to the sigma update tool and ran that and it updated without issue.
I think Sony's firmware update tool has some sort of hack that overrides Mac OS X's security features that allows the update.
it is working even with latest 10.15.5, after enable the security settings for Sony Corporation. thx !!!!
i hadn't installed any memory cards in the body. maybe important cause Sony Updater is sometimes tricky.

Note I am not responsible if this bricks your camera or lens but it worked for me on OS X10.15.4. I did not try any other approaches so YMMV.
for 10.15.3 it doesnt work this way
