Levo help · How Levo works

How Levo stays light in the background

A tool that watches your Mac shouldn’t be what slows it down. On a Mac mini, averaged over 30 minutes, Levo uses about 0.2% of the CPU and 0.1% of the memory.

Quiet by default

• A light check, not a loop. Levo reads free space, memory pressure, CPU and GPU at the interval you set, and when your Mac wakes. That’s a handful of cheap system calls.
• Per-process numbers on demand. It measures individual processes only while a limit is crossed, or while the popover is open.
• No rescan. The disk index is built once, at background priority, and can be paused. After that Levo follows file changes as macOS reports them and re-measures only the folders that changed. If Levo is closed for a while, it asks macOS for what changed in between and catches up from there.
• Nothing runs while you don’t need it. The agent is started only when a limit is near or crossed, never on a timer.

The agent is the one expensive part

Your agent’s runs use your plan or API key, and a little CPU. Levo keeps them small:

• Items it has already judged aren’t sent again unless they changed. A second run only covers what’s new.
• One run at a time, and each run has a limit on time and steps.
• A limit on automatic runs per day. Once it’s reached, Levo waits until tomorrow.
• An option to pause on battery below a charge level of your choosing.

You’ll find these in Settings › Agent.

Make it lighter still

• Raise Check every in Settings › General. Longer uses a little less energy, and catches problems a little later.
• Lower Runs per day.
• Turn off the metrics you don’t care about in their panes.

Checking it yourself

Open Activity Monitor and find Levo. It sits near the bottom of both the CPU and memory lists. While it indexes after you first open it, expect a short busier stretch.
