Please let us know if this solved your issue or if need further assistance.

Hi Pk,

Just the normal action of opening a photo... you click on it and it opens. Now it opens in a firefox browser window. This has never happened before.

See:

• https://www.google.com/search?q=mac+default+application

So what did you do about the above instructions and what where was the result ?

Am not a Mac person so you need to go through it's settings also to find the what to do when .......

Some info to know if ... : re: iso/tiff https://en.wikipedia.org/wiki/Preview_(macOS)

4th one down the list : https://apple.stackexchange.com/questions/182536/why-cant-i-see-thumbnails-in-the-finder

So this is a Mac issue please follow it up further if that did not solve your issue in the Mac forums.

Hello Pk,

For now I chose the default application to open photos as preview. It was already chosen but perhaps it needed a refresh. Seems to be working for now. Thanks for helping.

Cheers, J
