AlDente 1.39.4 Mac

The app runs on Apple Silicon and Intel MacBooks that have macOS 12 Monterey or later installed. Setting it up starts with one core decision.

How to cap a MacBook battery charge with AlDente

1. Launch AlDente. The menu bar icon shows your current charge percentage and battery temperature.
2. Click the icon and drag the charge limit slider to a value between 20% and 100%. Many users land on 80% for a desk-bound machine.
3. Plug in the power adapter. AlDente stops charging once the battery hits the limit you set, even while the adapter stays connected.
4. Enable Heat Protection in the app’s settings if you work in a warm room. It pauses charging automatically when the battery temperature climbs too high.
5. Check the status panel occasionally. It tracks battery health, cycle count, and current temperature so you can spot changes early.

The idea is straightforward: holding a lithium-ion battery at 100% for weeks adds stress. A fixed lower ceiling reduces that wear. Heat Protection adds a second safety net, pausing the charge if the internal sensor reports a spike. The app handles the rest in the background. The current release, version 1.39.4, tidies up a visual glitch that appeared in the popover on early macOS 27.2 betas.

Forgetting the battery still needs to breathe

First-time users often set a charge limit and then forget the battery still needs to breathe. A MacBook left at a fixed 75% for months without ever discharging below 20% can develop calibration drift. The percentage readout stays accurate, but the battery’s internal model of its own capacity slowly wanders off. The fix is simple: schedule a monthly full discharge down to 15% and let it charge back to your chosen ceiling.

Another common slip is disabling macOS Optimized Battery Charging and assuming AlDente does everything that feature did. The system setting still matters for how the Mac schedules top-offs before your morning alarm. AlDente controls the ceiling, but it doesn’t mimic the learning routine Apple built. Keeping both on tends to work better than pitting them against each other.

Some people drag the charge limit slider to 50% on day one, thinking lower equals safer. That forces the battery to cycle more often when they unplug for a meeting, which wears it faster than a moderate 70-80% limit would. The sweet spot is the highest percentage you can live with while still staying under 100% most of the time.

Heat Protection trips automatically at 35°C by default, and new users sometimes interpret that as a fault. A paused charge in a warm café isn’t a bug — it’s the app doing its job. Lowering the threshold in preferences suits hot climates, but 35°C is a reasonable starting point for most rooms.

Real-world scenario: the remote front-end developer

Consider a front-end developer working from a co-working space three days a week and from a desk at home the other two. They use a 14-inch MacBook Pro with Apple Silicon, spending mornings on npm builds, afternoons in Figma, and the occasional video call. At the shared desk, power outlets sit behind a monitor arm, so the machine stays plugged in for six-hour stretches.

Before AlDente, this developer’s battery sat at 100% during every co-working day. After nine months, coconutBattery showed capacity down to 92% of design. With a charge limit of 78%, the MacBook now hovers just below the stress zone during those long plugged-in sessions. On home days, the developer unplugs for lunch and lets the battery drift down to around 40% before reconnecting. Sailing Mode kicks in once the limit is reached, so the power adapter runs the machine directly and the battery slowly self-discharges over hours — no micro-cycling, no trickle charge.

The app’s menu bar readout became a quick glance habit: temperature at 31°C, cycle count ticking up slowly, health holding steady. After six months with this routine, the battery capacity reading is still 92%. The decline flattened.

Two settings to check in the first 48 hours

The first 48 hours set the tone. Right after dragging the app into the Applications folder and launching it, take five minutes to walk through the preferences pane. The defaults are sensible, but two settings deserve attention early.

Turn on launch at login. AlDente needs to be running the moment the power adapter connects. If the app starts after the system has already pushed the battery to 100%, the limit applies only on the next charge cycle. The menu bar helper can be set to open hidden, so it stays out of the way.

Calibrate within the first week. Apple’s battery controller relies on occasional full cycles to read capacity accurately. AlDente’s Calibration Mode automates this: it discharges the battery to 0%, then charges it uninterrupted to 100%, then drops back to your set limit. Run it once when the app is new, then again every two to three months. The first calibration establishes a trustworthy baseline for the health percentage you see in the status panel.

After calibration, pick a charge limit you can live with during a normal workday. If you rarely unplug, 75-80% is a solid starting range. If you unplug often but return to a desk within a couple of hours, 85% might suit you better. Watch the cycle count over the first week and adjust upward if you find yourself draining the battery too low too often.

During those early days, glance at the temperature readout a few times while running heavier software — a compiler, a virtual machine, a game. If the battery routinely nudges past 36°C under normal use, lower the Heat Protection threshold to 33°C in preferences. The brief pause is barely noticeable and pays off over months.

Workflow: monthly calibration from start to finish

Calibration Mode is the closest thing to a maintenance routine the app asks for. Here’s a step-by-step workflow for a monthly run on a machine that typically sits at a 75% charge limit.

1. Pick a quiet afternoon. Calibration takes a few hours, so start it when you won’t need to unplug. A Sunday with light browsing and email works well.
2. Open AlDente’s menu and select Calibration Mode. The app warns that it will discharge fully and then charge to 100%. Confirm the prompt.
3. Let the discharge run. The screen stays on during this phase. Keep working normally — the battery drains at its usual pace. The menu bar icon shows a calibration indicator so you know it’s active.
4. Watch for the shutdown warning. When the battery approaches 0%, macOS displays its standard low-battery alert. Save open documents. The Mac sleeps once the battery depletes.
5. Plug in the power adapter. AlDente takes over after the Mac wakes. It charges straight to 100% without pausing, then automatically drops back to your 75% limit. The calibration flag clears itself.
6. Check the health readout. After the cycle finishes, the status panel shows an updated battery health percentage. Note it somewhere — a small change month to month is normal; a sudden drop of more than 3% warrants a second calibration to confirm.

The whole process requires almost no babysitting. The app handles the discharge-charge sequence and returns to normal operation on its own. For users who downloaded AlDente specifically to preserve a battery already showing wear, this monthly routine provides a concrete number to track, replacing vague anxiety with a trend line.

Version 1.39.4 addresses a visual issue. The popover displayed incorrectly on the first macOS 27.2 betas, and that rendering glitch is now resolved.
