The bug with Canon RAW files (no Quick Look, etc.) has not been fixed. See latest post here https://forums.macrumors.com/thread...rk.2454415/page-3?post=33863586#post-33863586

Anyone updated a M1 Mac from 15.4 to 15.4.1 yet? Any problems?

Since 15.4, the bluetooth sound output volume has been ridiculously low. I had to crank the volume through the roof just for my XM streaming to an Anker BT speaker. 15.4.1 resolved this.

Multiple reboots for this update on my MacMini Intel 2018... and looooong wait! All looks fine, finally!

My experience was the opposite. Bluetooth volume was fine but became ridiculously low after updating to 15.4.1.

I did and had no problems.

Wonder if making changes in Sound Effects settings (alert sound, internal/external speakers, etc) to something different... restarting, then changing back to your preferred settings (and restarting again?) will help at all.

Shouldn't be necessary to kludge after a security update, but could be worse 🫤 ?
