Specifically, I'm writing a plugin that I want to be capable of updating itself. I figure the steps I should follow are: (Assuming a new version is available) 1 - Download the updated version. 2 - Move the current version bundle to the trash. 3 - Move the updated version bundle to where the current version bundle was. 4 - Launch/load the updated version. 5 - Terminate/unload the current version. What seems like it could be a snag in my plan is here: https://developer.apple.com/library...nceptual/LoadingCode/Tasks/NameConflicts.html So... is it not possible for me to update the plugin without restarting the entire app? I'd rather not annoy the user with the update process or place a burden on them having to manually do it... Does anyone have experience with writing self-updating applications or plug-ins?
