Very backwards (haha sorry couldn't resist).

Nope - forwards only

Hi Guy, I need a secondary Fuji X to back-up my X-H2 cheeply.   I sold my X-T2 to get the X-H2 beause I wanted to increase my AF hit rate. That being said, can you comment on the hit rates between X-H1, X-T3, and X-T4 in 2024? With all having the latest firmware, is there a big jump in AF performace between the three? Thanks, Tomek  

oh wow, that is very odd.  Can you not simply put any version you want onto a formated SD card, and install it like every other priece of hardware on the planet?   @botty have you tried a different lens, or updating the firmware on your lens (if thats the only one you have one)?

A while back Apple put a security update in its operating system that requires users to give permission for USB C or Thunderbolt connected devices to transfer data back and forth between the device and the computer. If the user did not give permission, the  device could only use the USB or Thunderbolt port for battery charging. Initially, this update was only for laptops, they may have brought it over to desktop computers later. As far as I know, if the user accidentally does not give access permission, there is no easy way to reset this for a single device, but there is sort of a work-around described in the release notes: https://developer.apple.com/documentation/macos-release-notes/macos-13-release-notes Does this help?
