[BUG]: Suspicious UI performance on macOS 15.5+ #1160

Description

@tdewey-rpi

What happened?

macOS 15.5+ users are reporting that with both 1.9.6 and 1.8.5, when Imager starts to ask the OS about the storage devices, the UI begins to jank - in some cases freezing for indeterminate periods of time.

1.9.6 included an always-in-the-background drive polling scheme, but 1.8.5 only polled the drives during selection.

Both appear to freeze at the start of the write.
