Photo's does not import my RAW files
I'm working with High Sierra, the latest version of Photo's and my PanasonicFZ90 camera. Photos does not recognise the files, I cannot import the pictures made in RAW. Same goes for PSE 14 and Preview. Preferences in Photo's are for download to iCloud and originals on iMac. Files are called .....RW2. Can anyone explain and or help?
