minor inconsistencies on macOS

[ixfd64]

On all my Windows machines, the manual communication feature shows three options: don't automatically contact the PrimeNet server, immediately contact the server, and send updated completion dates. But on both my macOS systems, I only see the option to not automatically contact the server. Is there a reason for this inconsistency?

I've also noticed another issue on macOS. One day after I set up Prime95 on a Mac Pro, the expected completion dates were sent twice during the same session.

I've only seen this happen once. This is a very minor issue and probably isn't even worth investigating, but I thought I'd put it here for the record.

Update: the second behavior doesn't seem to be specific to macOS because it just happened on a Windows laptop.
