macOS Golden Gate 27.3 beta 1 adds a Pro Light screensaver that animates the wallpaper of the MacBook Pro with PROLED XDR Display. In the screensaver, light travels slowly along the PRO lettering and lights up different sections while the rest fades into darkness.
The artwork comes from the PRO wallpaper for the laptop Apple announced on October 28. Only registered developers can install the beta, so most Mac owners will not see the screensaver until the update is public.
The Pro Light screensaver sends light along the PRO lettering
The wallpaper is oversized PRO lettering drawn with fine silver-blue lines on a black background. Basic Apple Guy recreated it as still files, 3456 x 2234 pixels for the 16-inch MacBook Pro and 5120 x 2880 for Studio Display, so the artwork is available without installing a beta. There is no 14-inch file, so owners of the smaller laptop would use the 16-inch version.
Those files are still images and do not animate. Apple took a similar approach in macOS Golden Gate beta 3, which added animated Golden Gate wallpapers that can also be set as a screensaver.

macOS Golden Gate 27.3 beta 1 also adds Rosetta notices and multiseat subscriptions
In the same beta, macOS now tells you when you use an audio plug-in or print dialog extension that needs Rosetta, and it shows those plug-ins in the Intel-based apps section of General settings. When you print with a driver that still needs Rosetta and has no Apple silicon update, macOS warns you about the printer driver and offers to install Rosetta if it is missing. AirPrint, built into most printer models, avoids the warning because it needs no driver.
Developers get multiseat subscriptions in StoreKit, which let a customer buy several seats on an auto-renewable subscription and invite other people to join it. Apps check support through the supportsMultiSeatPurchase property, which follows the setting in App Store Connect. A known issue in the beta keeps Siri on the Mac from finding app entities donated to Spotlight by third-party apps unless those entities conform to a schema.
Tandem OLED gives the PROLED XDR display deep blacks
The MacBook Pro with PROLED XDR Display uses a tandem OLED panel with two self-illuminating pixel layers, which Apple says keeps blacks deep without blooming or halos. It reaches up to 2000 nits of peak HDR brightness and a 10,000,000:1 contrast ratio. The display engine also tracks each pixel’s usage over time and adapts to preserve image quality, a form of burn-in mitigation.
The laptop opened for pre-order on October 28 in 30 countries and regions, including the United States, and units start arriving to customers on Friday, November 6. Models with M5 Pro start at $2,899 for the 14-inch and $3,399 for the 16-inch.
