MacOS 26.4 Adds ‘Slow Charger’ Indicator for MacBooks

Tim Hardwick at MacRumors:

macOS Tahoe 26.4 includes a new slow charger indicator that tells MacBook users when their charging setup isn’t delivering full power. As described in an updated Apple support document, a “Slow Charger” label now appears in orange text in the battery status menu and above the Battery Level graph in Battery settings. The indicator is accompanied by an info button for more details.

Apple says that to charge more quickly, users should use a power adapter and cable that deliver at least the minimum wattage recommended for their MacBook model.

This might be especially useful in Europe, where MacBooks no longer come with power adapters. Regular people often have no idea how power adapters work, and presume one charger is as good as another, if it works at all. After I posted this item back in October about the new MacBook Pros not shipping with chargers anywhere in Europe (not just the EU, even though it’s an EU law that requires products to be available without included chargers), a bunch of readers regaled me with tales of a family member complaining about their MacBook losing battery life even while plugged in, only to discover that they were using wimpy 5- or 10-watt USB-C adapters.
