Why is Aperture is getting stuck updating vault
Hi I am having trouble with the vault backing up. It seems to freeze, as does the program- I am unable to close Aperture or do anything once it gets stuck. I am trying a new vault because I purchased a new External HD. Does anyone have any ideas? I have a large library so I let it run over night thinking that was an issue, but the status bar did not change. Thank you
