When I download a DMG via Safari, the usual steps once the download completes is "verifying disk image...mounting disk image...cleaning up" and then it should be complete in the downloads window. however, i've been having this issue where the download gets stuck at "cleaning up". to get it to get out of the download window, i have to quit out of safari after it asks me if i'm sure i want to quit since there is an active download in progress (even though it is technically done downloading). the files are labeled with the .download extension so i have to mess with the file name and open the DMG manually. does anyone know about this issue and how i can fix it? it is a nuisance to me and i don't recall when it first started. thanks for any help!
