Apple's updated the raw file support for iOS, iPadOS, and macOS this month. Unfortunately, they still haven't caught up with High efficiency raw (Zf, Z8, Z9), but they also haven't caught up to the Z50II or Z6III at all. Even an intern shouldn't have taken eight months to support Lossless compressed on a Z6III. Heck, I bet they could even do it in three months (Z50II).
