Robert, I’m battling through this myself. It appears the issue here is that the ‘quarantine’ that is being mentioned is OS X literally moving our application to a temporary DMG and run from there. This DMG is a read only drive, so the structure is locked, and so is the data file if it is part of the application package. This has not been happening to us on all Sierra upgrades, but I have one now that no matter what I do or where I put the application, it is moved from where I am running it. From all the reading I’ve done in the last week, it appears my only option is signing the app itself, or as mentioned here, possibly the DMG that we use to send our app. It’s definitely new behavior with Sierra. Apple has finally removed the “Allow from anywhere” option in the Preferences > Security & Privacy page, although there is a Terminal command we can use to bring it back. Unfortunately, that still doesn’t stop this quarantining from happening. I just wish it would happen on all Sierra systems so there was at least some consistency.
