Description

I keep seeing a couple of minor warnings when building, in the macOS broker code for Desktop. Since we have no warnings anywhere else I thought I'd fix those. In doing so I also found a Clippy warning for an if inside an if let that was just as trivially fixed.

How Has This Been Tested?
