I skipped the 2.435 update and went straight to 2.449. MD600 update was a matter of minutes. I had to power cycle my MS200 once.

I installed the Sooloos app update on my iPhone and iPad too. Fixes I noticed immediately: Aspect ratio of artwork looks correct and you can see the track name in Now Playing.

Sooloos Update I see in Control:Mac is still 2.435, which I have not yet applied.
