MacOS 26.4 Beta 4 Now Available, Here’s What’s Coming

Why It Matters

The updates enhance productivity and battery longevity while nudging developers toward Apple‑silicon‑only apps, positioning macOS 26.4 as a more polished and future‑ready platform.

Key Takeaways

• Safari compact tabs return in macOS 26.4.
• Window‑resize pointer bug finally fixed.
• Native Charge Limit setting added for battery health.
• Rosetta‑2 usage triggers user warnings.
• Beta 4 build number 25E5233c released.

Pulse Analysis

Apple’s macOS 26.4 developer beta 4, build 25E5233c, arrives ahead of the public launch, bringing a handful of user‑focused refinements. The most visible change is the return of Safari’s compact tab bar, a UI element that was removed in the previous major release and has been a frequent request from power users. Alongside the visual tweak, Apple finally resolves the long‑standing window‑resize pointer glitch that misaligned the cursor with the window’s corner, improving precision for designers and developers alike. These adjustments underscore Apple’s commitment to polishing the macOS experience before the final rollout.

Another headline feature is the native Charge Limit setting, which lets users cap battery charging between 80 % and 100 %. By giving macOS a built‑in tool to manage charge cycles, Apple addresses a common concern among laptop owners about long‑term battery degradation. The option aligns with the company’s broader sustainability agenda, promising extended device lifespan and reduced electronic waste. Early adopters can already test the setting in the beta, and analysts expect it to become a standard configuration in the final macOS 26.4 release.

Finally, macOS 26.4 introduces proactive warnings for apps that still rely on Rosetta 2, signaling Apple’s accelerated plan to retire the translation layer in macOS 27. The alerts give developers a clear deadline to migrate native Apple‑silicon binaries, reducing performance overhead and tightening security across the ecosystem. For enterprises with legacy Intel‑only software, the notification system provides a transition window, but also pressures IT teams to prioritize recompilation or alternative solutions. As the beta cycle continues, the community will be watching how Apple balances backward compatibility with its silicon‑first roadmap.
