Apple has released an update to the macOS Monterey operating system, the fourth major update since its release in October 2021.

macOS Monterey‌ 12.4 comes out two months after the launch of macOS Monterey 12.3. One of the important innovations was the Universal Control function.

The initial announcement of Universal Control took place almost a year ago – in June 2021. In March, with the release of macOS Monterey 12.3, it began to work in beta mode, and now there has been an official release, which Apple considers hassle-free. Universal Control lets you use one keyboard and mouse to work on your Mac and iPad.

For Studio Display, ‌macOS Monterey‌ 12.4 adds support for firmware 15.5, which is designed to improve the quality of the webcam. There’s also an update to the Podcasts app that lets you limit the number of episodes you keep on your Mac and automatically delete old podcast episodes.

Apple has also added more than fifty fixes for security vulnerabilities in macOS 12.4. The ‌‌‌‌‌‌macOS Monterey‌‌‌ 12.4 update can be downloaded from the Software Update section of System Preferences.

McDonalds has introduced a smart smoke detector in the Netherlands that looks like an upside-down Big Mac. The device is called McDelivery Detector, and this name well reflects its essence.

The sensor is supposed to be installed on the ceiling in the kitchen. When smoke is detected, McDelivery Detector will prompt the user not to bother with further cooking, but simply to order something from the McDonalds assortment instead of what burned out on the stove or microwave. If the user agrees, the order is automatically routed to the nearest McDonalds restaurant.

McDelivery Detector is only available as part of an advertising campaign in the Netherlands. In order to enter the giveaway and get one of the sensors, participants in the game must submit examples of “their worst culinary mistakes.”

In the US, an interesting lot appeared at the Goldin auction – an Apple I computer from the first batch autographed by Steve Jobs. The description of the lot says that this is “the holy grail for collectors of vintage computers.”

The serial number 01-0050 is marked on the computer, and it is applied by hand and by the hand of Steve Jobs. It is emphasized that the device is operational – this was confirmed by Daniel Kottke, one of the first employees of Apple. The kit also includes a power supply, Sanyo VM-4509 monitor, Datanetics keyboard, and cables. Along with the computer, the winner of the auction will receive a reproduction of the original manual, autographed by Apple co-founders Steve Wozniak and Ronald Wayne. The current bid is 250 thousand dollars, but most likely the final cost of the lot will be higher.
