New

More in the menu bar. Beside the battery percentage, the menu bar can now show the time remaining, the power and the battery temperature. Choose them in General, under "In the menu bar, show", where a preview shows what the menu bar will look like.

• Time remaining: on battery, macOS's own estimate, the same as Activity Monitor shows, for example "3:42". Just after you unplug, macOS takes a minute or two to estimate; until then it shows "–:––".
• While charging, the time to your charge limit, for example "↑0:48". macOS counts to 100%, which a Mac held at a lower limit never reaches; Liwu counts to the limit you set. Nothing is shown while the Mac is held at the limit, and Liwu leaves the estimate out when it cannot be sure where charging will stop.
• Power: on battery, what the battery supplies; on power, what the adapter delivers.
• Battery temperature, in the unit you chose in System Settings.
• The numbers keep their width as they change, so the icon does not shift.

It is free.

New

Keep Awake turns on by itself. Keep Awake can now start while one of the apps you choose is running, while your Mac is connected to power, or while an external display is connected, and stop when that ends. It is part of Liwu Pro. Set it up on the Keep Awake page, under "Turn on automatically".

• With two or more conditions on, choose whether any one of them is enough or all of them are needed.
• While Keep Awake is on by itself, the menu bar popover shows why, for example "Notes running · On power". The info button beside it lists each app with its icon.
• An automatic session has no timer. To give it one, choose a duration in the popover; choose "Automatic" there to go back.
• If you turn Keep Awake off yourself while a condition holds, it stays off until the current conditions have ended. Turning it on again brings it back the way it was: automatic, or with the duration you chose.
• Your scope, display and low-battery settings apply to automatic sessions too.

Fixed

• When Keep Awake ended with the lid closed (its timer ran out or the battery reached your limit), the Mac stayed awake until the lid was opened. Liwu now puts the Mac to sleep in that case, unless an external display is connected or another app is keeping the Mac awake.

Changed

• The lock that marks a Pro feature now sits on the switch or button it belongs to, and the purchase prompt opens beside that control.

New

Bluetooth off during sleep. Liwu can turn Bluetooth off while your Mac sleeps with the lid closed, so a Mac in a bag does not connect to the headphones you are using with your phone. It is part of Liwu Pro. Switch it on in the menu bar popover, or on the Battery Health page below the sleep report.

• Liwu turns Bluetooth off only when the lid is closed and no display is connected. A Mac asleep with its lid open, or closed with an external display, is left alone, so a Bluetooth keyboard and mouse can still wake it.
• When you wake the Mac, Liwu turns Bluetooth back on. If Bluetooth was already off before the Mac went to sleep, it stays off. Your keyboard, mouse and headphones reconnect as macOS reconnects them, which can take a few seconds.
• The first time you switch it on, macOS asks you to allow Liwu to use Bluetooth. Without that permission Liwu does nothing and says so, with a link to the setting.
• It works while Liwu is running.

Improved

• Heat Protection while the Mac sleeps. A pause in force when the Mac goes to sleep now ends once the battery has cooled, the next time macOS briefly wakes the Mac in the background, instead of lasting until you wake it. Charging then goes on while the Mac sleeps. If macOS does not wake the Mac in the meantime, the pause lasts until you do, as before.
• While the Mac is asleep, no new pause begins.

New

Heat Protection. Liwu pauses charging while the battery is hot, until it has cooled. It is part of Liwu Pro, on the Charge Control page below Sailing.

• You choose the temperature, from 35°C to 45°C; it starts at 40°C. While the battery is charging at or above it, Liwu pauses charging where it is until the battery is 3°C cooler.
• After a pause your limit and Sailing range apply as before. Inside a Sailing range, charging starts again only once the level falls below it.
• While charging is paused, the menu bar popover and the Charge Control page say so, with the battery's temperature, and Liwu sends one notification.
• A Top Up that is running is paused with everything else and continues afterwards. Top Up cannot be started while charging is paused. Calibration is not paused.
• Liwu checks while the Mac is awake. A pause in force when the Mac goes to sleep lasts until you wake it.
• It needs the firmware charge limit, like Sailing and calibration, and is not offered on a Mac where macOS does not give apps that access.

Liwu does not cool the battery. It stops adding charge while the battery is hot.

Improved

• With power readings shown, the battery icon in the popover's bar now shows whether the battery is charging, discharging or holding, like the icon in the menu bar.
• With a limit below 80% or Sailing, the second level beside the battery level is rounded up, the way the firmware acts on it. A battery held at the lower end of a range no longer reads as one point below it.

New

Low Power Mode. A row at the bottom of the Energy Use page sets macOS's Low Power Mode.

• Never, Always, Only on Battery and Only on Power Adapter are the same four choices as in System Settings → Battery. Free.
• On Battery at a Level: Liwu switches Low Power Mode on when the battery falls to the level you choose, from 10% to 50%, and off again once it has charged above that level. This one is part of Liwu Pro. It works while Liwu is running; when Liwu quits, Low Power Mode stays as it is.

Changed

Energy Use now lists the apps macOS itself counts as using significant energy. It reads the same account as the battery menu in Control Center, where an app counts with everything it started. The first version read each process's processor energy and missed processes that live only for a moment, so heavy work such as a software build could read as almost nothing.

• The list no longer shows watts: macOS's measure has no unit. Each app shows one to three bars for the level it reaches.
• A menu beside the list's name sets the level from which an app is listed: Low, Medium (the level macOS uses for its own list) or High.
• "Include background processes" also lists system processes and background items. It is off unless you switch it on.
• Last Hour and Last 12 Hours, part of Liwu Pro, now show each app's share of all energy use in the period, in percent. macOS keeps this record itself, so it is there right after Liwu starts.
• In the menu bar popover, "Using Significant Energy" appears only while an app is listed.

Liwu only reads this from macOS; it does not change how apps run.

Improved

• Limits below 80% on a Mac where macOS does not give apps access to the firmware charge limit. Liwu now sets such a limit as macOS's own charge limit and shows it as waiting until macOS has applied it. If macOS has not applied it after ten minutes on power, Liwu changes your limit to 80%, tells you, and offers 80–100% from then on. Sailing and calibration need the firmware limit and stay unavailable on such a Mac. If you set a limit below 80% this way and later go back to an older version of Liwu, set a limit of 80% or more first.
• The check for firmware support no longer turns a Mac down because of values its firmware stores while the firmware limit is switched off.

New

Energy Use. A new page in the main window shows which apps are using energy, highest first.

• Now: each app's average power over the last minute, in watts. Free.
• Last Hour and Last 12 Hours: the energy each app used, in watt-hours. These two are part of Liwu Pro. Liwu keeps this record in memory while it runs, and starts it again when Liwu restarts.
• The five apps using the most right now also appear in the menu bar popover. A switch in General, under Appearance, turns that list off.
• An app's helper processes are counted with the app.

What is counted is the processor energy of your own apps and background items, as macOS itself accounts for it. The display, graphics and macOS system processes are not counted, so the list adds up to less than the Mac's total power. Liwu only reads these numbers; it does not change how apps run.

Improved

• A reserve way to set the charge limit. If macOS's direct way of setting it cannot be used on a Mac, Liwu now sets the limit through macOS's saved settings instead. macOS applies such a change itself, usually within about a minute, and Liwu shows the target as waiting until it has. On Macs where the direct way works, nothing changes.
• When charge control is not available on a Mac at all, Liwu now says so in the popover as well as in the main window, and sends one notification when control is lost. Top Up, plans, Sailing and calibration no longer show a lock or the purchase prompt there, and the notice has a "Report this Mac" link.

New

Three ways to show and hide the Hidden group of menu bar icons without clicking the arrows. They are in Menu Bar settings, under "Show and Hide", and are part of Liwu Pro.

• Hide again. After you show the Hidden group, Liwu hides it again after 5 seconds to 1 minute. The time starts once the pointer has left the menu bar, and waits while a menu you opened is still open.
• Shortcut. Record a key combination that shows or hides the Hidden group from any app.
• Show on hover. Rest the pointer on the empty part of the menu bar, between the app menus and the arrows, and the Hidden group appears. It then hides again by itself.

The three groups, the arrows in the menu bar and moving icons between groups stay free and work as before.

Improved

• On a Mac where limits below 80%, Sailing or calibration are not available, Liwu now says so in plain words, and says that buying Pro does not change it.
• Liwu no longer offers the Pro purchase for calibration on such a Mac, and the purchase prompt says what Pro adds on your Mac and what is not available on it.
• A "Report this Mac" link next to these notices opens a prefilled report with your Mac model, macOS version and Liwu version. Nothing is sent until you submit it.
• The note about settings from Liwu 1 now says what was not carried over, and can be dismissed.

Fixed

• With the main window and the menu bar popover both open, the purchase prompt appeared twice. It now appears once, beside what you clicked.

New

• Sleep report. Battery Health now lists each time your Mac slept: how long, the battery level before and after, and how often it woke briefly and why. It is read from the Mac's own power log, which goes back about a week.
• If a sleep on battery uses much more than usual, Liwu tells you once after you open the lid. This is part of the Low battery notifications.

Brief wakes are normal, and macOS schedules most of them itself. The report shows what happened; it does not change how your Mac sleeps. It is free.

New

• Adapter details. Open Power details from the information button on the battery bar to see what macOS reports about the connected power adapter: its name, rated power, the voltage and current in use, the port, and every voltage it offers, with the one in use marked.

Liwu shows only what the system reports, so some adapters show fewer lines. It is free.

New

• Low-battery alerts at a level you choose. Liwu warns you once when your Mac reaches that level while running on battery. Set it in General, under Notifications.
• Accessory battery levels. Accessories that report their battery level to macOS are listed in the menu bar popover, and Liwu warns you when one runs low. You can hide the list in General, under Appearance.

Both are free. The alerts arrive once you have turned notifications on.

New

• Liwu is now available in German, French, Spanish, Brazilian Portuguese, Korean and Japanese. It follows your Mac's language; to choose one yourself, open General and use Language.
• The Buy and Restore links in the app open the website in the same language.

Improved

• When a plan started a Top Up, the note on the Top Up button now labels the plan and the time it was scheduled for.
• Chinese: Top Up and Sailing are now shown by their Chinese names everywhere in the app.

These translations have not been reviewed by native speakers yet. If something reads wrong, write to support@liwu.app.

Improved

• The Limit menu now ends with "Add preset…". It opens the preset editor with your current limit already filled in.
• You can type the target in the preset editor, as well as use the stepper.
• If you have never saved a preset, Liwu now starts you with one: Desk, at 80%. It is an ordinary preset, so you can rename or delete it.

New

• Plans can now start Top Up. Choose Top Up as a plan's action and it turns on at the scheduled time when power is connected, for example an hour before you usually leave. It ends like any Top Up: when you unplug, turn it off, or quit Liwu, and your regular target stays the same.
• If power is not connected at that time, or calibration is running, that run is skipped and the Schedule page says why. With notifications on, you are told as well.
• A Top Up that a plan started is marked "Top Up · Plan" in the popover, and the charging details name the plan and the time.

Fixed

• Corrected the captions under a plan's catch-up switch. Without catch-up, a plan runs only at its scheduled time; the old text suggested a longer window.

Good to know

• Plans run while Liwu is running and your Mac is awake. A Top Up plan set for a time when the Mac is asleep does not wake it.

Improved

• Liwu Pro pricing changed. The unlock button and the upgrade prompt no longer show a price; the current price is shown on the website and at checkout.

New

• Added notifications. Liwu can tell you when battery calibration finishes or ends early, when a charging plan does not run, when Keep Awake turns itself off, and when charging control needs attention. They are off until you turn them on in General, or with the switch on the Schedule, Charge Control, or Keep Awake page.
• Added a Battery Health page. It records maximum capacity and cycle count once a day while Liwu is running and charts them over time. Readings stay on your Mac, and you can export them as CSV.

Improved

• Maximum capacity and cycle count moved from the Charge Control status list to the new Battery Health page.

New

• Added arrows to the menu bar: click them to show or hide your Hidden group without opening Liwu. Right-click the arrows to open Menu Bar settings.
• Added an Always Hidden group for menu bar icons you want out of the way. The arrows never reveal it; move an icon to Hidden or Visible when you need it again.

Improved

• Moving an icon between groups now waits for macOS to finish updating the menu bar before placing it, which makes moves more reliable.

Known limits

• On a crowded menu bar with a display notch, macOS may not accept a move whose drop point falls behind the notch. Liwu reports that the move was not confirmed and leaves your groups unchanged.

Fixed

• Fixed hidden menu bar icons staying visible after restarting your Mac, with a "Could not restore the saved group" warning that refreshing did not clear. Your Hidden and Visible groups are now kept across restarts.
• Fixed hidden menu bar icons sometimes reappearing for about a second at launch before being hidden again.

Improved

• When using a charging target below 80% or Sailing, the battery bar now shows a raw capacity estimate alongside the macOS battery percentage when they differ. An explanation button helps clarify why the battery may stop at a different displayed percentage.

Fixed

• Fixed an issue that could prevent the background component from being registered again after its system records were cleared, leaving charging controls unavailable even after clicking Retry.

Fixed

• The background helper now exits after quitting Liwu once charging cleanup is confirmed and Keep Awake has been released. It stays available while cleanup is unresolved or a new Liwu session is using it.
• Homebrew uninstall now asks Liwu to release charging control and remove its background registration before deleting the app. Removal stops if cleanup fails.

Note

• Homebrew upgrades and reinstalls also perform this cleanup. If you use Launch at login, enable it again in Liwu afterward.

Improved

• Unavailable controls now explain why they cannot be used. Persistent warnings share a clearer layout, and repeated low-target warnings are combined.
• Charging Retry stays visible with a loading indicator until the result is confirmed, then clears on success or becomes available again after failure.
• Keep Awake explains low-battery protection before activation and why a session stopped. Historical stop notices can be dismissed.
• Calibration shows specific start requirements and explains the brief reconnection window when power is unplugged.

Fixed

• Fixed incorrect preset explanations when Sailing is enabled but charging control is not ready.
• Fixed a main-window layout issue caused by long warning messages.
• Opening the menu-bar popover no longer automatically focuses the charging-limit field.

Fixed

• Fixed an issue that could stop calibration during discharge when macOS battery-capacity readings updated more slowly than live battery readings. Valid samples are no longer rejected solely because the two sources update at different times. Missing-data and low-battery safety checks remain in place.

New

• Added Sailing for Pro: keep your charging limit as the upper endpoint and choose a drop of 5–20 percentage points before recharging. The lower endpoint stays at 20% or above. Sailing requires supported firmware controls, even with a limit of 80% or higher.
• The battery bar now shows the Sailing recharge threshold alongside your limit, with both markers moving together as you adjust the target.

Improved

• Low charging targets, calibration, and Sailing check firmware support before becoming available. Messages explain which feature is unavailable, and unsupported calibration actions are disabled in the schedule editor.
• Schedule targets can now be entered directly as numbers. Plans are checked against the active Sailing range before saving and again before running.
• Charging controls show clearer pending, failed, and unknown results, and restore the current value when an edit cannot be accepted.

Fixed

• Saved menu bar groups now retry restoration during startup without requiring you to open the Menu Bar tab. Quitting cancels pending restoration and reveals the icons. Group restoration still depends on the original menu items remaining available; restarting other apps or macOS can require regrouping.

Fixed

• Fixed a timing issue when replacing the background component after an update. Liwu now waits for the previous component to finish stopping before registering its replacement, preventing charging controls from remaining unavailable until the app is restarted.

Liwu 2 brings everyday Mac tools together, with charging targets and Keep Awake at its core. This version requires macOS 26.7 or later on an Apple Silicon MacBook.

• Set the macOS charging target from 80% to 100%, and save named presets for quick access. macOS manages charging, discharge, and its own battery calibration.
• Use Top Up to temporarily request 100%. Your regular target remains editable and returns when you end Top Up, unplug, or quit Liwu.
• Schedule charging targets with independent values, repeat rules, optional catch-up, and skip-next controls.
• See pending changes, confirmed targets, and retry options directly in the Limit control. The battery bar continues to show the actual battery level.
• Keep Awake remains available, including timers, low-battery cutoff, and Pro support for keeping the lid closed.
• Enabling charging management explains and turns off Optimized Battery Charging once. If you turn it back on in macOS, Liwu respects that choice and offers a button to turn it off again.
• Existing Liwu 1 Pro purchases also unlock Liwu 2 Pro.

Liwu 2 does not include limits below 80%, custom heat-based charging pauses, charge-related sleep rules, sailing or range mode, active discharge, or automatic calibration. Liwu 1 remains available for macOS versions before 26.7 and will receive no further feature updates.

Quitting Liwu ends Top Up and requests your latest regular target. It does not restore the charging settings from before you opened the app. Scheduled changes require Liwu to be running; missed tasks follow your catch-up setting.

Fixed

• Charging limits work again on macOS 26.6 after Apple changed the battery control interface
• Liwu now detects when macOS Charge Limit stops charging below Liwu's target and explains how to avoid conflicting charge controllers

Improved

• Charge Control now shows setup guidance to set macOS Charge Limit to 100% and turn off Optimized Battery Charging

Fixed

• Sleep is no longer left disabled if Liwu is force-quit while Keep Awake is on — a closed-lid Mac could otherwise stay awake and drain the battery
• Heat protection no longer resumes charging after a single bad temperature reading
• Calibration now stops and shows the reason when the adapter is unplugged or a step cannot finish, instead of staying stuck
• Settings no longer revert when you change several of them in quick succession
• Charge controls stay disabled until the background component reports its current state, so an early click can no longer reset settings to their defaults
• Scheduled tasks sync reliably when the background component takes a while to start, and no longer run twice after a failed write
• Skipping the next scheduled run now reports a failure instead of appearing to succeed when its timing has already changed
• Narrowing the range no longer starts an unnecessary charge cycle
• A charge limit typed in the menu bar popover is no longer lost when the popover closes
• Battery health no longer reports an invalid 0% maximum capacity
• The macOS Optimized Battery Charging conflict warning now appears for limits just above 80%
• Monthly schedules use the same day of the month on every calendar setting
• The main window now opens reliably after activating from the website
• Fixed a rare case where an activated license could be lost while upgrading from an early version

New

• Let the display sleep while Keep Awake continues local agents, builds, tests, renders, and downloads
• See clear warnings when system, display, or lid-closed sleep control cannot be applied

Improved

• Keep scope, display, and duration controls compact in the menu bar popover
• Report the lid scope that actually took effect when closed-lid control fails

New

• Guide new users through enabling Liwu's background helper on first launch

Improved

• Keep the Liwu icon visible when background access needs attention, making the alert easier to identify

New

• Start Liwu automatically when you sign in, controlled from General settings
• Show or hide the battery percentage in the menu bar

Improved

• New installs now use the Liwu icon in the menu bar by default
• Background helper problems are now explained consistently across the app

New

• Update notes now appear right here in this dialog, so you can see what changed before installing
• The full history is at liwu.app/changelog

Note

• This release contains no changes to the app itself

New

• Buy Pro on liwu.app — your Mac is activated automatically once checkout completes
• Restore Pro on a new Mac, or after reinstalling, using the email you purchased with

Improved

• After activation the main window opens to General, so you can confirm your Pro status at a glance
