So I'm on a trip in India with my 1dxmkii and my old macbook running lightroom 4 on Yosemite 10.10.5.
When I try to import my CR2 files I get a message saying that the format is not supported and I cannot update my OS to allow a newer version of lightroom (Or at least not lightroom 6 which I know suports the format) so I'm not quite sure how I can bring them into lightroom at all.
Now I normally edit on my imac back home but I'm kind of stuck with this laptop for the duration of my travels (3 months) and would hate to have to wait till I was back home to start on them.
