Hi, I'm having issues with permissions in the above OS. So far I have only noticed it occurring with image files mainly because that is the file type that I generally use. Randomly I will select all of the images in a folder and hit "Command O" to open them in preview and I get a message that says that I cannot open them because I do not have permission. When I check the file in the "Get Info" tab, I do have all of the relevant permissions that should allow me to do what I want. When I restart the Mac I try and do exactly the same and it opens all of the image files, no problem. Then a few folders later I will get the same message. So restart and again I can open them... I have already tried one permission fixing solution the other day using the terminal and it seemed to work, but just now I am getting the same issue. What is going on? I notice that Apple have messed around with the way permissions work in the OS lately and I'm wondering if this meddling has screwed it up some how. Never had an issue like this before... Any ideas?
