Tahoe 26.5.1 iMac. Been having an issue with images lately both from downloads and today some of my own that I airdropped from an older iMac to this one. If I try and open the image I get a prompt saying I do not have permission. Even if I try and unlock it the thing goes back to locked again. The way I have been getting around this is to do a restart and all is well for awhile till it pops up again. I probably went about 6 months or better before it first popped up about a week ago.
Any ideas?
