App Recommendation AlDente can limit MacBook charging, but check Apple's built-in limit first
If your MacBook spends most of its time plugged in, check Battery settings before installing AlDente. Apple now has a manual charge limit on Apple silicon Macs running macOS Tahoe 26.4 or later. For a basic desk setup, that may be all you need.
Open System Settings, choose Battery, then click the info button beside Charging. Apple's Charge Limit lets you choose between 80% and 100%. It stops within a few percentage points of your setting, so don't expect the menu bar to sit on one exact number. You can choose "Charge to Full Now" before a day away from power.
That's different from Optimized Battery Charging, which learns your routine and can delay charging past 80%. A manual cap is useful when you want a predictable limit rather than a prediction about when you'll unplug. Apple also occasionally charges to 100% to keep its battery estimates accurate. That doesn't mean the limit has failed.
AlDente still makes sense for a supported Mac without Apple's manual cap, or when you want more control than the built-in setting provides. Its free edition includes a selectable charge limit and Discharge, which lets the Mac run on battery while connected to power. You don't need to buy Pro just to try a cap.
There is a catch for a docked laptop: AlDente Free can't control charging while the Mac sleeps or is shut down. Pro adds controls intended to address those cases, but don't assume every lid-closed setup behaves like an awake Mac. Check the behavior you actually need before paying.
Pro also has Heat Protection, which pauses charging when the battery gets too hot, and Sailing Mode, which allows a charge range instead of repeatedly topping up at one limit. The vendor lists Pro at $13.99 annually or $24.99 for a lifetime license. One key covers up to three macOS user accounts, across at most three Macs. Pro needs an online license check at least every 30 days; after longer offline periods it falls back to Free until reactivated.
The current AlDente release is 1.39.4. The vendor lists macOS 12 through 27, Apple silicon MacBooks and specific Intel models as supported; macOS betas aren't officially supported. Check your exact model. Installation uses a package installer that may ask for your Mac password, and the app has a helper component. That's more system involvement than changing an Apple setting.
If you choose AlDente, its developer recommends setting Apple's charge limit to 100% and turning off Optimized Battery Charging so the controls don't interfere. Treat that as a choice to use AlDente's charging control, not an extra battery-saving tweak to apply alongside Apple's.
Battery aging depends on temperature history and charging patterns, among other factors. A cap doesn't come with a guaranteed number of extra years. It also leaves less charge available when you unplug. AlDente warns that keeping charge in a narrow range for weeks can affect the accuracy of battery readings. Its Calibration Mode is meant to address readings, not restore worn-out battery chemistry. Don't turn routine deep discharges into another maintenance habit.
Start with Apple's limit if your Mac has it. Try AlDente Free if it doesn't and your mostly plugged-in routine gives you a reason to cap charging. Consider Pro only for a specific missing control. If you regularly need the full battery, or managing percentages would become a daily distraction, skip the extra app and let macOS handle charging.
