What is UI Scene lifecycle all about? Where is more information about this?

While using a variety of apps in MacOS15 beta 6 & 7 they will freeze. It seems like they happen when you stop typing in Pages or while doing something Preview. Forcing it to quit and restarting sometime allows sometime more progress but it is very slow. Printing is unworkable. This first started in Beta 6 and I hoped Beta 7 would fix it but no, it seems to be worse. I'm using a Mac M2 Mini with 24 Gb of memory. No problems with Mail or Safari. Haven't tried working with Xcode

I'm trying to add a USB mic to my Mini runing the latest Sonoma software but it full of crackles. Why isn't it clean?

Am using App Wrapper to submit my app to the App Store. It reports: Signing info. 3rd Party Developer installer .... Expires 2024-03-21 .... Missing SHA1 hash, may fail on macOS 10.11 or before... I've completely reloaded all my certificates with no change. What do I need to do to load my app successfully?

Rebuilding my app after a year of inactivity now gives me this weird message: 2023-02-21 16:29:59.960014+1300 Cluedo Pal[3999:2024218] [SceneConfiguration] Info.plist contained no UIScene configuration dictionary (looking for configuration named "(no name)”) My app uses Storyboard and I'm using Xcode 14.2 Here's an image of the Info,plist /Users/robinharrington/Desktop/Image 21-02-23 at 5.00 PM.jpeg

I'm a developer of a Mac app and when I try to download it on a test system, I get this message "Unable to download app" with the suggestion to try again later. I did that and still get this message. The test system is a MacBook Pro running MacOS 11.3.1. What else can I try to get some kind of diagnostic of the problem? An earlier version of the App is running on the system.
