The latest batch of betas of macOS 26.2 It's already here, focusing on more professional video calls and computing-intensive tasks. In Spain and the rest of Europe, a growing number of test users are evaluating these features before the general launch, paying particular attention to Edge Light The new option to interconnect multiple Macs is now available.
Apple has published Developer Beta 3 and Public Beta 3 macOS Tahoe 26.2 (build 25C5048a) is expected to be released after a somewhat unusual schedule in the preceding weeks. If all goes well, the stable release is slated for... DecemberIn any case, it's advisable to install betas carefully, with a backup made and without risking the main computer.
Edge Light: virtual lighting that takes advantage of Apple Silicon
Edge Light adds virtual lighting to the edges of the screen for a more flattering image during video calls; thanks to the Neural EngineThe system detects the face, its position and size to place the lighting precisely and without annoying artifice.
In addition, the image signal processor can automatically adjust The brightness adjusts to the surrounding environment, while the user has manual control to switch between warm and cool tones. If you move the cursor towards the edges, the light temporarily hides to avoid interfering with desktop tasks.
In terms of compatibility, the function requires Mac with Apple Silicon (M1 or later) It works with both the built-in camera and external cameras, including the Apple Studio Display. On devices manufactured from 2024 onward, Edge Light can activate automatically when ambient light decreases.
The setting appears in the video calling apps themselves, alongside options like Portrait Mode or voice isolationIt's a discreet upgrade that can save on lighting fixtures in both home and professional settings without complicating the setup.
Mac clusters over Thunderbolt 5: up to 80 Gb/s and lower power consumption
macOS 26.2 incorporates a low-latency option for linking multiple Macs using Thunderbolt 5unlocking connections of up to 80 Gb/s. The idea is simple: create clusters with standard TB5 cables and compatible equipment to run large local models without specialized hardware.
This possibility is not limited to the costly MacStudioIt also includes Mac mini with M4 Pro MacBook Pros with M4 Pro or M4 Max are already supported. In demonstrations, groups of four Mac Studio computers successfully loaded and ran the Kimi-K2-Thinking model. 1 billion parametersshowing remarkable efficiency compared to PCs with high-power GPUs.
A key point in Europe is energy consumption: a cluster of four Mac Studios can be below 500 W Working with large models, while desktop GPU configurations easily exceed 575W per card (as is the case with some RTX 5090s). In labs, universities, and SMEs, the operational savings can make all the difference.
In parallel, Apple offers full access to the framework. MLX to the neural accelerators of the M5 familyThis accelerates local inference in AI workloads. However, there is a practical limitation: the currently available 14-inch MacBook Pro with the M5 chip has Thunderbolt 4 ports, so it cannot take full advantage of this feature. clustering via TB5; it does, however, benefit from the improvement in inference with MLX.
For the most demanding users who are missing a Mac Pro refresh, this strategy of software cluster It offers a viable alternative to scale performance with equipment already present in many European environments.
Urgent reminders and performance adjustments
The Reminders app introduces the label "Urgent" In macOS 26.2 and iOS 26.2 for timed reminders: when activated, an alarm will sound on the iPhone or iPad when the time comes, with options to snooze for nine minutes or mark the task as completed.
This coordination between Mac and iOS devices reduces the likelihood of missing important alerts, which is useful during hybrid workdays. The “Urgent” marking appears in the reminder's detailed view and integrates with notifications across the iOS ecosystem. Apple .
In terms of stability, several testers point out that the public beta 2 It has mitigated the slowdowns experienced with iCloud in Desktop and Documents since macOS 26.1, especially when saving files or exporting Pages documents. As always with test software, the experience may vary depending on your workflow.
Beta status and how to install them on your Mac
Apple is currently distributing Developer Beta 3 and Public Beta 3 of macOS Tahoe 26.2 (build 25C5048a), following a somewhat atypical schedule in previous weeks. The pace suggests a version with few alterations "under the hood" beyond Edge Light and minor tweaks.
- Make one Backup from your Mac.
- Open System Settings → General → Software Update.
- Tap the “i” icon next to Beta Updates.
- Choose macOS Tahoe 26.2 (Developer or Public Beta).
- Confirm and restart if the system prompts you.
For Spain and the rest of the EU, registration in the public program is done in beta.apple.comAs a precaution, it is best to test these versions on secondary equipment or with a clear rollback plan, avoiding risks in production environments.
With a package that combines more carefully managed video calls, a way to accelerate loads of AI with TB5 clusters And with small productivity improvements, macOS 26.2 outlines an update that, without fireworks, aims for a real impact on the day-to-day lives of users and technical teams in Spain and Europe.
