White thumbnails new macbook air

[snerkler]

I've just bought my wife a new Macbook Air which is running OS Sequioa and some photos in finder are showing as completely white, but if you open it in preview you can see the photo.

A quick google show that this has been a common issue, however these threads are from months and even over a year ago. Has there been a fix for this yet please and if so how do I fix it please?

What is the file format of the photos? What device did the photo files originate from?

They're jpeg from her iPhone. Another odd thing is that so files that show their thumbnails properly can then show as white when transfered to another folder, but it's very random.

A fix I've used for now is to open them in preview and then export as a new jpeg, they then display the thumbnails properly.

Probably just a corrupt QuickLook cache, if a restart doesn't fix it.

Try

qlmanage -r cache

and I believe they should start popping back up.

I would recommend against that, as it causes generational quality loss from recompressing the images.

Thanks, is that a terminal code?

It is. It just resets the QuickLook thumbnail cache.
