iOS isn't upgradable.

I can't check the macOS builds or comment on the workflow, unfortunately.

macOS Ventura 13.4 Client and Server open correctly. Listening works ok. Speaking doesn't work unless I start the app from terminal as it doesn't ask for recording permissions. This might be a bug on my machine only.

@gilgongo could you please test if this also happens to you?

I'm on Ventura 13.4.1 (c) - seems to work OK for me (no permissions problem at least, and I can hear and I think transmit OK but I didn't do complete test of that). Settings and connect windows came up in the background for some reason - I had to manually foreground them.

Almost certainly more Qt6 issues...

Hmm ok. So the SDK update is probably valid. But what should we do about the buggy Qt?

[ann0see]

I think we should be able to upgrade the SDK then.
