Apple’s fourth beta for macOS Monterey 12.4 also includes a second beta firmware for the Studio Display, Apple’s premium display.
Issued on Tuesday, macOS Monterey 12.4’s fourth beta had an extra element, providing an update to the Studio Display. The version 15.5 beta update is the second for the display, following the first Studio Display Firmware Update 15.5 from the third Monterey 12.4 beta.
It is unclear exactly what the firmware changes for the Studio Display, but it is likely to include another attempt at a fix for the 12-megapixel ultra-wide webcam. The display had initial quality issues for the webcam, but Apple tried to improve the image in the release by taking advantage of software updates.
In AppleInsider’s testing of the first beta firmware, skin tones were improved, with less noise seen on the screen. Center Stage was also tweaked to be less aggressive when cropping the picture.
The beta update is available to developer testers through System Preferences on Macs running the latest macOS beta, with it listed as an Apple Studio Display Firmware Update.
AppleInsider, and Apple itself, strongly recommend users don’t install the betas on to “mission-critical” or primary devices, as there is the possibility of data loss or other issues. Instead, testers should install betas onto secondary or non-essential devices, and to make sure there are sufficient backups of important data before updating.
