Check the trash behavior with an unwanted item
P
Unlike many other issues involving the inability to trash, or to keep an item from re-appearing, my iMac had just developed a quirk that is concerning. As with my Macbook pro, I have always been able to drag an item(s) to the trash, and until I empty the trash - to see those items and even drag them out. Now i still can do that with the Macbook, but not the iMac. As soon as I drop an item in, i get a msg asking me if i want to delete this item, as it will be unrecoverable. Sure enough, drop drag and drop it into the trash and it disappears - permanently, no sign of it at all in the trash. No, the box is not ticked in the Finder preferences, to Empty Trash Securely.
Any clues that will help restore back to the former situation will be welcomed. I do back-up, but only at the end of the day, and dropped a music file into the trash accidentally, thinking it was an unwanted copy - and it was very much wanted. That's when i discovered this new quirk ![]()
Why is this so?
iMac - 3.06GHz Intel Core 2 duo; 4GB SDRAM; running 10.6.4
I am running 10.6./4 on the Macbook pro as well.
