This has me baffled. Canon's 5D MkIV is one of the most widely used pro-sumer DSLRs around yet Apple have not provided any RAW support for it. I contacted Canon & they said it's not their issue, the problem is on Apple's side as Apple has ready access to everything they need. I contacted Apple & they said the problem is Canon hasn't given them what they need. In the meantime I've had to buy Lightroom to access my RAWs (please don't mention Canons appalling software bundle...) They have RAW support for masses of other new cameras & Canon cameras yet they've decided not to support one of Canon's most popular models. I mean seriously? What gives?
