Shooting in Raw With MacBook Pro

This list of cameras tells you, which cameras are supported in Mojave: Digital camera RAW formats supported by iOS 12 and macOS Mojave - Apple Support

You can work with the RAW formats of these cameras in Photos for Mac.

But you mention iPhoto. The RAW support for iPhoto is stuck on the RAW support released with El Capitan: For iPhoto check this list: Digital camera RAW formats supported by OS X El Capitan - Apple Support

You're welcome, Barbara 😊

I was wondering that, too. AFAICT, all the cameras on the list shoot JPEGS, too.

Are there any cameras that shoot only in Raw? Pretty sure that every camera offers Jpegs too. Also, even if Photos doesn't meet your needs other apps like CaptureOne, Lightroom etc will work with Raws that sometimes Photos doesn't support.
