Hi Peter

What about in Photos or Preview?

Sounds like it might be a bad card? Are the raw and jpeg files on separate cards?

What are you using to view the raw files. Which camera?
Are you using an Adobe product? Do you have the latest raw convertor?

What app? They could be reading the embedded JPG and there is some anomaly that is causing it to display incorrectly. Are they all up to date?

It's initially showing you the embedded jpeg thumbnail...

Sounds like a faulty card to me as well. I don't know Nikon kit but as others have asked are you using a camera with dual cards ?

What have you used to transfer the images to your iMac? I've heard similar before relating to card reader problems. Could you try downloading them directly with a cable from your camera and see if that helps.

Problem solved thank you all so simple thanks again.
Happy Now

What fixed it Peter, the direct download? Oh, and welcome to TP by the way!

No worries. No such thing as stupid questions either when you're starting out.
