The behavior you describe has been the way the App Store has worked since
the first major macOS update after its release; I wouldn’t expect that to
change. Your users are likely *already* using Big Sur, at least some of
them, on beta versions.

Hi Eric,
This sounds achievable. You can embed interface objects inside of a
WKInterfaceGroup, and that group can have a background image. So you’d put
the group in with your background image, and then inside of it would be the
semicircle image. Does that sound like it would work?

The recommended approach here (I think) is to show the notification on

That sounds like the perfect use case for using the MultipeerConnectivity

It's always felt like a hack to me, but this will run the run loop for a short
time and return:
[[NSRunLoop currentRunLoop] runUntilDate:[NSDate date]];
Though in your case, if the first thing it does is process your input stream,
that doesn't help.

If you’re creating the web view in -viewDidLoad, you should probably release

While that’s true for some classes (NSManagedObjectContext springs to mind)
I think a more general way to say it would be “In most cases, although you
can allocate instances of these classes on any thread, refrain from
messaging an instance from more than one thread simultaneously.”
Jeff Kelley
Agreed. You wouldn’t go to the hardware store and try to build something
using every product they carried.
As for the English, Wikipedia has an article for “Witch’s Broom” in English,
so I would go with the first (“Cocoa Witch’s Broom”). Not that I would build

Blocks do retain objects that are passed in, so that's probably what's
happening. Also, keep in mind that autoreleased objects aren't freed
immediately; it happens when the run loop completes. You should always act as
if it does happen immediately, but it isn't always true.
If you need to make the computer sleep immediately, you can use the command
"/usr/bin/pmset sleepnow".
