Here’s how, and how to fix problems. ## Install and set up 1. ### Download and open Open Chargeberry.dmg (4.9 MB) from your purchase email or the download link, drag Chargeberry to Applications, and open it from there. 2. ### Approve the helper The welcome installs Chargeberry’s helper. macOS asks you to allow it once in System Settings › General › Login Items & Extensions; the welcome shows exactly where. 3. ### Activate your license Paste the license key from your Gumroad receipt when Chargeberry asks, or later in Settings › General › License. 4. ### Choose a limit Daily (80%) is a good start. Chargeberry checks for anything that would get in the way, like Optimized Battery Charging, and tells you. **Needs:** macOS 14 Sonoma or later on a MacBook with Apple silicon (M1 or newer). Intel Macs aren’t supported. ## Your license Your key is in the email from Gumroad. It works on up to 3 of your Macs. Lost it? Email [adgan.business@gmail.com](mailto:adgan.business@gmail.com) from the address you bought with and we’ll send it again. Chargeberry checks the license about once a day when it can; being offline never locks you out. ## On macOS 27 macOS 27 locked the charging controls Chargeberry uses on earlier versions, so there it sets macOS’s own charge limit instead. Your limit (80% to 100%), Charge to 100%, Full by and its schedules, shortcuts, alerts, health and Battery Wrapped keep working; limits below 80%, drain down, calibration and heat pausing are off there. [More about macOS 27](https://chargeberry.app/guides/macos-27-battery-charge-limit/) ## If it isn’t holding the limit - **Check the menu.** Chargeberry’s menu says what it’s doing and why, and shows a note if something needs your attention. - **Approve the helper.** If the menu says the helper isn’t allowed, turn Chargeberry on in System Settings › General › Login Items & Extensions. - **Turn off other things that control charging:** Optimized Battery Charging, macOS’s own Charge Limit (on macOS 26.4 and later, unless you’re on macOS 27), and other battery apps such as AlDente, BatFi, batt or Battery Toolkit, including their helpers. - **Expect the odd 100%.** macOS charges fully now and then to check the battery, and a Mac that’s shut down while plugged in charges to 100%. [All the reasons](https://chargeberry.app/guides/why-does-my-mac-charge-to-100/) > According to Chargeberry’s own tests, when the process holding a charging switch was killed, normal charging came back within 1 second. If the app or its helper ever stops, the Mac goes back to charging normally rather than not charging at all. — Measured by Chargeberry: Chargeberry’s crash-safety test, part of its hardware self-test, run on a MacBook Air (M1, 2020) on October 28, 2026: a client holding the charge switch, then the charger switch, was killed with kill -9 while the switches were read back from the battery controller.

It restores normal charging, removes the helper and everything Chargeberry saved, frees this Mac’s place on your license where it can, and moves the app to the Trash. If you had set macOS’s Charge Limit yourself on macOS 27, it’s put back as it was. ## Contact Email [adgan.business@gmail.com](mailto:adgan.business@gmail.com). You’ll hear back from the person who makes Chargeberry. For news and quick questions, there’s also [X](https://x.com/ayeshagagan). ## Common questions **Why does Chargeberry need a helper and my approval?** Changing how a Mac charges needs system privileges, so a small helper does it, and macOS asks you to allow it once in System Settings › General › Login Items & Extensions. The helper only changes charging, only accepts requests from Chargeberry itself, and puts charging back to normal if anything goes wrong. **What happens if I quit or uninstall Chargeberry?** Quitting the app leaves your limit in place: the helper keeps it. Settings › Advanced › Uninstall Chargeberry puts charging back to normal and removes the helper and its data. If you just drag the app to the Trash, the helper notices, restores normal charging and leaves on its own. **Can I use Chargeberry on more than one Mac?** Yes. One license works on up to 3 of your Macs. Replacing a Mac? Email adgan.business@gmail.com and we’ll free up its place. **Will Chargeberry slow down my Mac or drain the battery?** No. About 0.1% CPU (0.13% on average, 0.4% at its busiest moment) and 13 MB of memory while it sits in the menu bar, and its helper about 0.03% CPU and 7 MB. The helper reads the battery’s sensors every few seconds and sleeps in between. **What is Battery Wrapped?** A monthly card about your battery: its health, the hours it was kept off 100%, its hottest moment and the cycles it used, with a berry mood. It’s made from what Chargeberry measured on your Mac, and nothing leaves your Mac unless you share it. **What if something isn’t working?** Email adgan.business@gmail.com and you’ll hear back from the person who built it. Saying which Mac and macOS version you have helps; Settings › Advanced shows Chargeberry’s version and what its helper is doing.
