Hi Damien,

Thanks very much. That seems to have done it!

 Some time ago I copied one of the many scripts out there that provides for auto-incrementing the build, and it defaulted to hex. I’ve switched to decimal and that works.

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/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.

According to Damien Sorresso, BSD Engineering, Apple Inc. (see https://lists.macosforge.org/pipermail/launchd-dev/2010-October/000834.html), "ServiceManagement will check the CFBundleVersion of the tool and, if it's the same ..., will not overwrite it."

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?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).
