Use Apple Intelligence for smarter workflowsWith macOS Sequoia and newer models supporting Apple Intelligence, the MacBook Air can now summarise documents, rewrite emails, organise notes, and surface relevant files automatically. Using system-wide writing tools and on-device intelligence improves productivity without sending data to the cloud. Enable these features in System Settings → General → Apple Intelligence. Use iPhone Mirroring and Continuity upgradesIn 2025, iPhone Mirroring is far more advanced. You can drag files between your iPhone and MacBook Air, continue apps seamlessly, and even receive iPhone-only notifications directly on your Mac. If you frequently multitask across devices, ensure both are on the same Apple ID with Wi-Fi and Bluetooth enabled for smooth continuity. Optimise battery life with Adaptive ChargingMacBook Air models now include enhanced adaptive charging that learns your routine and prevents the battery from staying at 100% for too long. This slows down long-term battery wear. Keep “Optimised Battery Charging” turned on in System Settings → Battery. Pair this with Low Power Mode for longer unplugged use. Use Stage Manager with external displaysThe 2025 macOS update finally brings better multi-display support for Stage Manager, giving MacBook Air users cleaner window layouts when connected to an external monitor. You can drag apps between screens without breaking the layout, improving workflows for editing, coding, and research-heavy tasks. Use Mission Control settings to refine your setup. Use offline Siri and dictationSiri now works offline for tasks like setting reminders, opening apps, managing files, and controlling system settings. This is useful when travelling or in low-network zones. Dictation is also faster and more accurate, letting you draft notes, emails, or documents hands-free. Enable voice features in Keyboard → Dictation. Manage storage with AI-powered cleanup toolsmacOS now suggests apps, duplicate files, old downloads, and unused system caches that can be safely deleted. The AI-driven “Recommendations” panel provides a more accurate storage overview, especially useful for base 256GB MacBook Air models. Find it in System Settings → General → Storage.
