Hi.
I have the latest version of PM: 5.0, build 18980 (60d39ba) installed on a MacBook Pro running the newest version Mac OSX High Sierra 10.13 (17A405).
This issue started after "upgrading" to High Sierra.
After ingest, the window pops up "Ingest Complete" as well as Mac's notification "Photo Mechanic:An ingest task has completed."
When I click on the Mac alert, PM crashes. When I reopen PM, it opens with an old contact sheet although I have the preference set to "open last contact sheet."
It's a minor bug, just wanted to alert the developers.
