Aperture Library not found on visible shared drive
Hi,
I have been using Aperture since 3.2 and now have Aperture 3.6 on Sierra.
The Aperture Library and the Original files are on an external Drobo 5D drive on a Mac Mini Server running Sierra also. (Before someone chimes in and says "Apple doesn't support this", well thanks but it has been working happily for about 8 years)
Suddenly when I open Aperture it comes up with "Library not found". I click "Locate" and navigate to the Library, click OK and it runs.
Anyone know what is causing this and how to fix this somewhat annoying new step of not seeing the clearly visible shared drive on the desktop.
I note that when I navigate to Desktop in the Finder the Shared drive icon is not shown but when I navigate by the server name it suddenly appears. Seems to be some sort of network protocol issue. OS is 10.12.6
Thanks in anticipation.
