Apple introduces a new slow charger indicator in macOS Tahoe 26.4 to alert MacBook users when their charging setup isn't delivering full power. The feature appears as an orange Slow Charger label in the battery status menu and above the Battery Level graph in Battery settings, accompanied by an info button for details. Apple recommends using a power adapter and cable meeting the [minimum wattage requirements](https://support.apple.com/en-us/109509) for optimal charging.

This update mirrors a similar feature in iOS 18, where slow charging is shown as an orange bar in the Battery section.
