Lidlezz keeps your MacBook awake for Claude Code, throttles everything the moment the lid closes, and puts the Mac to sleep before it gets hot or the battery runs low.

Claude Code's own hooks tell Lidlezz when a session starts, works, waits for a usage limit or finishes. The mode switches on by itself, and two minutes after the last session ends the Mac goes back to normal sleep.

Open the lid and it all comes back.
Lidlezz reads the SoC die sensors straight from IOKit, read-only, no root. At 85° it throttles harder. At 95° it saves the session, puts the Mac to sleep and shows the exact resume command when you open the lid.

The CLI ships inside the app. Run the mode in a terminal, check temperature and battery, list sensors, or change the two settings without opening the menu bar.

Keeping a closed Apple Silicon Mac awake needs root for one command. A small signed helper runs it, accepts calls only from Lidlezz's Team ID, and touches nothing else.
pmset disablesleep on and offtmutil onlyFrom a big refactor on the train to an overnight migration on the kitchen table, Lidlezz keeps the session alive and the Mac in one piece.
Start a task at the desk, close the lid, ride home. Claude Code keeps going on efficiency cores while the Mac stays cool in the bag.
Migrations, test suites, dependency upgrades. Let them finish while you sleep, with a battery floor so the Mac never drains to zero.
Claude Code hits a usage limit and waits. Lidlezz knows, keeps the Mac awake through the reset, and resumes the moment work continues.
Close the lid, walk into the room. The task carries on in the background and the fans stay quiet on the table next to you.
Hours of file edits and tool calls. Lidlezz watches the heat every three seconds and throttles harder before anything gets uncomfortable.
Pick the percentage where the mode turns itself off. Lidlezz stops before the battery does, and your session is saved either way.

Everything you need to know before closing the lid, from what needs root to what happens when the Mac gets hot.
A menu bar app for Apple Silicon Macs that keeps the Mac awake while Claude Code runs, throttles everything when the lid is closed, and puts the Mac to sleep before it overheats or runs out of battery.
On Apple Silicon the only way to stay awake with the lid closed is pmset disablesleep, which requires root. A small signed helper daemon runs that command and nothing else. macOS asks you to allow it once in System Settings.
That is the whole point. Lidlezz reads the SoC temperature every three seconds. At 85° it throttles harder, at 95° it saves the session and puts the Mac to sleep. It also enforces a battery floor you choose.
Claude Code keeps its own session state. When you open the lid, Lidlezz shows the exact claude --resume command so you pick up where it stopped.
Yes. With an external display attached macOS already stays awake, so Lidlezz skips the lid-closed throttling and only keeps watching temperature and battery.
You can turn the mode on manually from the menu bar or run lidlezz in a terminal. Automatic start and stop rely on Claude Code's hooks, which Lidlezz installs for you.
Apple Silicon MacBooks on macOS 14 Sonoma or later. Usage-limit awareness needs Claude Code 2.1.234 or later.
After purchase you get a key in the form LZ-…. It is Ed25519 signed and verified on your Mac, offline. Paste it once under Enter license… in the menu bar panel.
Yes. One license per person covers all the Macs you own.
No. There is no account and no telemetry. The only network request is a check for a new version on launch and every six hours, which you can see in the panel.
Yes: brew install --cask witcharon/tap/lidlezz. A DMG is also available on the releases page.
Claude Code and its child processes move to background QoS on the efficiency cores, Low Power Mode turns on, and Time Machine and Photos analysis pause. Opening the lid reverts all of it.
