I did report this, back in 2013 too (and possibly beyond this too). I also reported it to various camera app companies. They were all already aware of the issue, but there is no Apple tethered input device working with filters any more, nor has there been since late 2013 as far as I can tell. My prompt here was frustration as I lost (again) some really nice photos, due to a forced limitation of the Apple software and photo import function. I used to use Apple products to aid a creative process, now I just find I'm often fighting with the software and wholly ruining the creative endeavour. The loss of Aperture, and (a fully working) iPhoto is a great loss to photographers using Macs. I was just hoping that after over two years, there'd be a solution.
At the end of all this, there's still no way to import filtered photos via a tethered (i.e., the safest method) to a Mac. This seems positively bonkers to me. Actually, when I'm feeling frustrated due to the loss of nice work for no real reason, it feels like a positively fascist shift in policy from my 'favourite' hardware/software provider. 1984…
I am pleased, Lawrence that your method works for you, but it is only perhaps practical for 'amateur' photos. It does not function at all as a viable method for pro, or semi-pro photographers. The use of a cloud in another countries jurisdiction IS a legal minefield. The jurisdiction is liable to change, or be hacked. Both have happened in recent years and the pressure for further erosion of privacy on cloud servers is massive at present. Anyway, I just want to plug in my Apple device to my Apple device and copy of my photos as I shot them. It isn't much to ask, is it? It used to work!
