Using iPython Notebook on OSX Yosemite to test pyatom - <atomac.AXClasses.NativeUIElement <No role!> ''>

[ericvalente]

I am getting this error when I try to run atomac.getAppRefByBundleId('net.app.app'):
<atomac.AXClasses.NativeUIElement <No role!> ''>

I believe it is because of Yosemite's OSX Accessibility settings/permissions. I tried adding Chrome and terminal to the "Allow the apps to control your computer" section of Security & Privacy but no luck.

Anyone know which application I need to approve in order to get iPython Notebook to work?

I'm also seeing the same issue when i run the script from the remote terminal using plink, but not when i ran it locally.

Also getting this in El Capitan......... it was working fine in Yosemite

Ok got it fixed by adding Terminal (or iTerm, the one I use) to the Accesibility app list. I forgot about that

Even I have added my app to the Accessibility app list, I still met this issue:
atomac.launchAppByBundleId('com.apple.Automator')
automator2 = atomac.getAppRefByBundleId('com.apple.Automator')
print automator2

<atomac.AXClasses.NativeUIElement <No role!> ''>
I'm using Mac OS 10.11.6, is it not supported? Thanks

If you were using an embedded terminal of an application other than "Terminal.app" you have to add that to accessibility as well. I was using Coda2 and not everything works.

Thanks a lot!

No problem :D

The cleanest way to handle this is to check for accessibility permissions in your script, and prompt the user to grant permissions if they're not found:

def request_accessibility_permission():
    b = objc.loadBundle('CoreServices', globals(), '/System/Library/Frameworks/ApplicationServices.framework')
    objc.loadBundleFunctions(b, globals(), [('AXIsProcessTrustedWithOptions', b'Z@')])
    objc.loadBundleVariables(b, globals(), [('kAXTrustedCheckOptionPrompt', b'@')])
    return AXIsProcessTrustedWithOptions({kAXTrustedCheckOptionPrompt: True})

if not request_accessibility_permission():
    print("Run me again after you've granted permissions")

This will pop up an OS dialog box to open settings and grant permissions to the appropriate app. Objc code is via the pyobjc mailing list.
