Updating Your Mac to Avoid Embarrassing Screen Sharing Mishaps
A few days ago, Apple launched a fresh update for Mac, but expect no new features or major changes like when upgrading to macOS 14 Sonoma. Instead, an update might save your virtual meeting's next disaster. According to Apple's Security Release Notes, macOS Sonoma 14.2.1 fixes a WindowServer bug that might accidentally share incorrect content during screen sharing. Oops!
This WindowServer bug is a core process in macOS responsible for drawing windows and other elements on the screen. It affects all macOS versions, making it not specific to any application. While the exact workings of this bug are unclear, it seems that macOS inappropriately displays the wrong window during video calls. The specific window it displays isn't clear, but it doesn't seem like the one you'd want to share with clients, coworkers, or your company.
If you often share your screen on FaceTime, you have several options: you can select a particular window, all windows within a specific application, multiple windows, or your entire screen. Choosing the last option means sharing potentially sensitive information on macOS versions prior to 14.2.1, so it's better to err on the side of caution. Since this bug affects WindowServer and not FaceTime specifically, it likely impacts all video conferencing applications and services, such as Zoom and Google Meet.
If you engage in screen sharing for work or pleasure, we recommend updating your Mac as soon as possible. Moreover, consider updating your other Apple devices as well: Apple has also released updates for the iPhone (iOS 17.2.1 and iOS 16.7.4) and the iPad (iPadOS 17.2.1 and iPadOS 16.7.4), even though they weren't specifically announced.
Upgrading to the latest macOS version
To eliminate the screen-sharing bug, follow these steps: 1. Navigate to System Preferences > General > Software Update. 2. Allow macOS to search for the latest updates, then click "Update Now" if macOS Sonoma 14.2.1 appears.
