AlDente 1.39

[davidwernhart]

AlDente 1.39 Coralli

All

• Completely rebuilt charge control with macOS 27 support and improved reliability on earlier macOS versions and Intel MacBooks, including after downgrading from the macOS 27 beta.
• Charge limits below 80% now require enabling a toggle in Charge Settings for the best experience with Apple’s new charge control systems.
• Reduced AlDente’s impact on WindowServer CPU usage.
• General stability improvements and bug fixes.

Pro

• Calibration Mode now automatically detects and integrates Apple’s battery calibration. After the initial charging phase, you can cancel or let AlDente complete the calibration for an even better result.
• Redesigned the Apps Using Significant Energy widget with Quit buttons, optional background processes, and improved app detection.
• Hardware battery percentage is now available in the stats widget and menu bar items catalog. Removed the previous toggle; charge control now always uses the macOS percentage.
• Fixed scheduled task start times resetting when changing the repeat interval.

Is there a reason why charge control in 1.39 always uses the macOS percentage and not the hardware battery percentage?

[MatthiasKerbl]

Hi @fabrica64,

Yes, unfortunately, Apple made some major changes under the hood in macOS 27, which essentially required us to rebuild the entire charging control backend from scratch.
Because of these changes and the way Apple’s new implementation works, it became technically unfeasible to use Hardware Battery Percentage as the triggering threshold for the charging control backend. We therefore moved this information to Stats and the menubar instead.

I hope you understand.

Best,
Matthias

Thanks for sharing!

There's no toggle in the charge section to re-enable charge under 80%, I normally use 55% for good reason (I have the paid Pro version). I still use Sequoia and have good reason to not move to the newer releases.

[MatthiasKerbl]

Thanks for sharing. Which macOS version exactly are you using? AlDente 1.39 works flawlessly on our test device running macOS 15.6.

[dikrek]

15.7.9, latest. Everything works apart from that toggle. It doesn’t even show as you can see from my screenshot.

[MatthiasKerbl]

Thanks for sharing. We are looking into it now.

[MatthiasKerbl]

Hi @dikrek,

We have just released AlDente 1.39.1, which includes a fix for this issue.
To update to AlDente 1.39.1, open the Dashboard, click on the gear icon in the bottom-left corner, and click on Check for Updates.
Please report back if it works for you.

Best,
Matthias

[dikrek]

works, thanks!!

[marcolaux]

I have a 3rd party battery. Can I cancel Apple's internal calibration? It never finishes for me.

[MatthiasKerbl]

Hi @marcolaux,

Unfortunately, we were not yet able to cancel Apple's battery calibration.

Best,
Matthias

[vinzlee97]

After upgrading, the app insists to perform a calibration even though I don't set any automatic calibration schedules. Hence, it disregards the charge limit and thus I downgraded to 1.38.1. Is this some sort of mandatory thing to do ? Can I opt-out of it ? Wouldn't want to return to the laptop and realize that the app suddenly full charges because of unknown calibration routine 🫤

[MatthiasKerbl]

Hi @vinzlee97,

AlDente will never automatically start a calibration if you don't have anything scheduled through Apple Shortcuts or the Schedule feature in AlDente. However, since macOS 27, Apple has implemented its own "micro" calibration by charging to 100% regularly. Unfortunately, so far we have not been able to stop Apple's own calibration. Therefore, we notify you when Apple's calibration has started and offer to continue running a full AlDente calibration.

Best,
Matthias

[vinzlee97]

Thank you for the reply, @MatthiasKerbl

Is there any ongoing plan to work around it ?

[MatthiasKerbl]

We are continuing to look into it, but so far we have not found a workaround for the Apple calibration.

[Alexen-Hin]

I wonder why it keeps calibrating my battery over and over again? I just charged to 100% few hours ago. With efforts, I made it down to 60%. While I replug it to the charger, it starts calibrating the battery and charging to 100%, which annoyed me so much. I just want to keep it arond 50-60% charged and do not calibrate so frently. It is on Aldente 1.39.2 paid pro on macbook air M3 15 inch.

We are still trying to reverse engineer Apple's own algorithms and will give updates once we know more about when and how Apple's calibration gets triggered.

[marcolaux]

This would be great. Esp. with a 3rd party battery Apple's own calibration never finishes. It is in this state forever. Aldente was a workaround for me before macOS 27 because I was not able to set the charging limit to 80% with macOS and the battery I have. Aldente worked on the other hand but does not anymore and I am unfortunately unable to do anything about it.

[Dreamer1008]

I'm experiencing the same issue after updating to OS 27. It's frustrating, but hopefully, since they've identified the problem, I hope they will release a proper fix soon, because the version 1.39.4 has not solved anything for this particular issue.

Oct 10th update: I think this new setting (see the attached screenshot) in Golden Gate is likely competing for control with AlDente.

[marcolaux]

@Dreamer1008 you also need to disable optimized charging in macos, this was also the case in macOS 26. otherwise aldente doesn't work as intended.

[Dreamer1008]

Optimized charging is always disabled for me. I only enabled it in the screenshot because I was trying different methods to get it to work, but nothing has been successful so far. My Mac's battery still overrides the charge limit and calibrates daily, which I'm concerned will significantly reduce its overall health. Interestingly, the charge limit slider on my Mac doesn't stay at my preferred setting. It automatically increases to 100% on its own, which only makes the issue worse.

[Alexen-Hin]

The same for me

Hi everyone,

A quick correction to my reply to @vinzlee97 from September 10: Since AlDente 1.39, AlDente Pro automatically continues with its own Calibration Mode when macOS starts its battery calibration, even if you don't have anything scheduled. Sorry for the confusion.

Here is what we know so far: The calibration itself is started by macOS, and it also happens on MacBooks without AlDente. Based on the macOS logs shared in #1850, macOS seems to request a full charge whenever the battery has stayed at the same charge level for about three days. @Dreamer1008 and @Alexen-Hin, this is probably why it happens so often for you, even with Optimized Battery Charging disabled. @marcolaux, on MacBooks with a replaced battery, macOS often doesn't finish the calibration at all.

With the next update, you will be able to choose in the Charge Control settings under "After macOS Calibration" whether AlDente continues with its full Calibration Mode or only discharges the battery back to your charge limit, which will be the default. Until then, you can stop the Calibration Mode as soon as macOS has charged your battery to 100% by unchecking Calibration Mode in the Dashboard.

We collect all details and updates on this topic in #1846.

Best,
Matthias

[Dreamer1008]

Hi Matthias, thanks for clarifying. In my case, macOS is forcing a charge to 100% almost every day, rather than after roughly three days at the same charge level. Optimized Battery Charging is always disabled.

I understand the upcoming update changes what AlDente does after Apple’s calibration, but my main concern is the frequency of those forced full charges. They make AlDente’s charge limit unreliable for daily use.

Are you investigating why calibration happens so frequently, and is there any workaround to prevent or reduce it? Would a debug file help identify what keeps triggering it on my Mac?

[MatthiasKerbl]

Hi @Dreamer1008,

Yes, we are looking into why macOS starts its calibration so often on some MacBooks. In the reports we have so far, this happens when the battery gauge stops updating certain measurements, with or without AlDente installed.

You can check this on your MacBook with the commands that @socquique shared in #1846: #1846 (comment)
If the DOD0 values haven't changed for weeks, that is very likely the reason for the daily calibrations. A debug file doesn't contain these values at the moment, so the output of these commands is more helpful right now. It would be great if you could share it in #1846.

Several users in #1846 reported that resetting the battery gauging preferences stopped the repeated calibrations for them. We can't say yet if this lasts, so please only try it if you are comfortable with it.

Best,
Matthias

[Dreamer1008]

Hi Matthias, thanks for the explanation.

Since switching to BattOpt, I haven’t experienced the repeated forced charges to 100% that were happening almost daily while I was using AlDente. I haven’t reset any battery gauging preferences, so I thought this observation might help your investigation.

I haven’t checked the DOD0 values yet. Would the command output still be useful while BattOpt is managing charging, or should I quit it before collecting the readings? I’d prefer to check those first before resetting any preferences.

[Alexen-Hin]

Looking forward to the update. Thx!

[DVS9000]

Hi,
Is this why today my macbook started an automatic calibration proces? I didn't start it myself and can't find any settings which triggered it. I prefer to choose when I want to calibrate. How do I prevent aldente (or my macbook?) from starting a calibration?
Thanks!

[MatthiasKerbl]

Hi @DVS9000,

Yes, this is most likely the macOS calibration: macOS sometimes charges the battery to 100% to calibrate it. It also happens on MacBooks without AlDente, and AlDente can't prevent or interrupt it. In AlDente 1.39, AlDente then continued with its own Calibration Mode.

With AlDente 1.40, you can choose what happens afterward with the new setting "After macOS Calibration" (Settings → Battery Care → Charge Control): "Discharge to Charge Limit" brings your battery back to your charge limit instead of running a full AlDente calibration. More details in #1846.

Best,
Matthias

[Alexen-Hin]

no idea to stop the trigger
