I have Fritzing installed on my Mac 10.12.5 running Version 0.9.3 (b5c895d327c44a3114e5fcc9d8260daf0cbb52806 2016-04-19) Cocoa [Qt 5.6.0]
I use Fritzing infrequently and started on a new project.
I do not seem to be able to show the Parts Bin.
When I checked for Updates I got a warning and tried to regenerate the parts database.
This failed with error "Unable to open temporary file"
Regenerating the parts database will take some minutes and you will have to restart Fritzing
Would you like to regenerate the parts database?
Unable to open temporary file
I reloaded Fritzing, which offered to update Parts, but failed in the same way.
Yet another reload which produced errors:-
Unable to find the following 13 parts:
I can run Fritzing, view my saved projects, and edit them, but cannot seem to get to Parts.
What can I do? I can live with losing all the existing parts.
