Thank you for your reply, what I was trying to do was update the firmware in my X-T2 and as I am new to this camera, and updates, I can only imagine that I was acting on an instruction I had read somewhere(or misread). Having used the method you recommend I find that my Mac Mini can’t open the file and I have both VLC and 5k Apps on board. I never had this problem with my Leica M3 or my Canon F1. Sorry about that but I took up photography in my early 20s and was given a digital compact camera for my 65th. I have had two more compact cameras since but of course they didn’t need updating. I purchased the very able Fujifilm X-T2 because my photography had become ‘Point and Shoot’. I am very happy with the camera - and I am working through the instructional manual - perhaps I should have updated my Mac Mini too? Thank you again. TF
