Hi James, "E6" is not a valid CFBundleVersion. CFBundleVersions are very specifically tuples consisting solely of three numeric elements as proscribed in https://developer.apple.com/library/content/documentation/General/Reference/... <https://developer.apple.com/library/content/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html#//apple_ref/doc/uid/20001431-102364> The daemon which backs SMJobBless() is strict in this regard. Because the version was invalid, it assumed a version of "0.0.0", and chose not to perform the update. -damien

I've updated my code to show the CFBundleVersion of the tool both before and after a "successful" invocation of SMJobBless(). Is there anything I can do to get this to work?

I am attempting to replace a helper tool. Most of the time if I increment the version (of my application and of the helper tool) then the new tool will be installed. Sometimes it won't be installed and I have to delete the old one manually. The problem seems to occur about every dozen versions or so, and once it happens the replacement will not occur even if I change the version numbers again.
https://developer.apple.com/reference/servicemanagement/1431078-smjobbless?l... <https://developer.apple.com/reference/servicemanagement/1431078-smjobbless?language=objc> states "If the job is already installed, success is returned.”
How does SMJobBless() determine that the job is already installed? What do I need to do, beyond creating an entirely new job name, to make it look different enough to replace?
Following is my code and console output (from macOS 10.12.2).
