Would it work if I run Siri on OS X El Capitan by copying
Siri.app from macOS Sierra to the OS X El Capitan?
Just want to find out what exactly would happen even though OS X El Capitan doesn't support Siri.
The app will show a prohibitory sign over the app icon.
When opening the App, it will show an error message.
Even if you managed to hack/crack/disable the check that prevents the Siri interface app from running, the parts of the system behind the scenes that actually run Siri on macOS, communicate to the network and process the speech recognition are missing on El Capitan.
So if the door on the second floor is locked shut because the deck hasn't been built yet - you can cut the lock and eagerly exit the door, but you'll promptly fall to the ground since the deck isn't built into El Capitan yet.
I think the only way is upgrade to Sierra Beta.
Yes, you might, providing the following:
At least that was what happened, by chance, to me, when I checked differences between the two operating systems. It could be that Apple deliberately excludes Siri from El Capitan. Perhaps not on technical grounds, though.
Sorry about being late here, but yes, you likely can. Find Siri.app, open it's
info.plist file, and change the
10.11. I'm going to look into what Siri.app requires to run, because this interests me, but if it won't open, please try running
/Applications/Siri.app/Contents/MacOS/Siri in terminal, and tell me what the error message is.
