MakeMKV now gives a "Fatal Error" upon launch. Reinstalled and rebooted and tried no extensions - all without success.
 
Scanning Error: All of my scans with Fujitsu X1600 come up blank. Uninstalled and reinstalled ScanSnap software without change. Any one else seeing this / any ideas? M4 Mac-mini Pro.

Apple has acknowledged the Virtual Machines issue in the release notes for 15.4 beta 1.

Virtual Machines

Known Issues

  • Upon update to macOS 15.4 beta 1, M4 Macs will be unable to launch virtual machines and attempts will result in a system restart. (145309647) (FB16542958)
    Workaround: Do not launch virtual machines. If virtual machine applications launch upon login, boot to Safe Mode and disable in system settings.

Installed this update on my M4 Pro 16” MBP - got a problem in that it boots to the desktop and about 20 seconds later it freezes and proceeds to restart

Any idea how to resolve?
Don't think you will be able to...I gave feedback to apple as desktop should never appear before the login window.
 
Local.app https://localwp.com/ (WordPress locally hosted) is not able to trigger the sudo prompt to modify /etc/hosts with this build.
I would strongly recommend including your hardware specifications. I'm not recognising any of these issues on my M1 MAX 64GB 2TB MBP. As indicated earlier there are issues with certain machines, and there are updates on the developer website to patch/fix it.
 
I face some known glitches after updating it. However, it's safe to update it. Although I liked the UI changes and the fact that Apple Intelligence is now available in many other languages.
