@bmke @grgarside sorry, in my post a few hours ago chat.stackexchange.com/transcript/message/22997675#22997675 I wrote the wrong path. The earlier post at chat.stackexchange.com/transcript/message/22931679#22931679 was correct.

Specifically, the 13D38 promotion of Feedback Assistant – in pre-release OS X 10.9.3 – was:

– from /System/Library/CoreServices/ (where the assistant was integrated with pre-release Mavericks before 13D38)

– to /System/Library/CoreServices/Applications/(where the assistant became both integrated and easily found with Spotlight).

Then 13D43 (my screenshot above) discreetly allowed seed testers in at least one project to discover the words "OS X Beta Seed Program" before the existence of that programme became public knowledge.

Not long after publicity began, for the programme for OS X 10.9.3 beta, Apple's instructions included a shot of an earlier version of the assistant showing an earlier version of the operating system – OS X 10.9.2 (Build 13C64) –

The fixed size and shape of those windows were, to me, a big hint that eventually Feedback Assistant would appear on iOS. Before the OS X Beta Seed Program publicity:

– and for the latter, I wrote "The window is shapely … food for thought …".

Now, in Apple's words, "… OS X and iOS public betas come with the built-in Feedback Assistant …". As words to that effect may be commonplace, so readers may assume that with other builds of the operating systems (with builds that are not public beta), there is no OS–assistant integration …

… given Apple's words, that assumption is reasonable. Reasonable, but false. Truly, the OS-assistant integration is not limited to public beta builds of OS X.

I can't comment on Feedback Assistant in any build of iOS; I left AppleSeed a year ago (see my profile).

What's above should be just enough to demystify the relationships between Feedback Tools, Feedback Assistant and OS X.

@robertklep unpack.py received with thanks, now (if you like) remove the link to your secret gist.

@stuffe On OS X, there's the Finder integration. On iOS 9, yes, there's a native iCloud Drive app that can be turned on in Settings.

@grgarside Found it - thanks
