Save your work before the battery dies.

Lifeboat sits in your menu bar and keeps an eye on the battery. At 10% it saves your documents and remembers which apps, windows and tabs you had open. If the Mac shuts down, it opens everything again when you turn it back on.

What happens as the battery runs down

When a Mac runs out of battery, files you already saved are fine. What you lose is anything you hadn't saved yet, plus all the windows and tabs you had open. Lifeboat steps in at three points.

20%1:51 PM

At 20%

Lifeboat starts checking what you have open every 2 minutes instead of every 10, and shows one notification to say it's ready.

You won't get permission prompts at this point. Lifeboat asks for everything it needs when you first set it up.

Lifeboat saves your documents, makes a note of everything you have open, and then tells you what it did.

What it saves

  • Documents with unsaved changes, using the app's own Save. It doesn't quit apps or click through Save dialogs.
  • Untitled documents, into a Lifeboat Rescued folder in Documents.

What it remembers

  • Your open apps, and where each window was on screen
  • Browser tabs in Safari, Chrome and other Chrome-based browsers
  • Finder windows, and the folder each Terminal tab was in
  • The clipboard
  • Saved by Lifeboat: TextEdit for now. Pages, Numbers and Keynote are next.
  • Already safe: apps that save as you type, like Notes.
  • Save it yourself: any other app. Lifeboat reminds you while there's still time.

If you want, it also turns on Low Power Mode and dims the screen. When you plug in, it switches them back.

At 3%, or with about 4 minutes left, Lifeboat saves once more. The edges of the screen turn red and a small card at the top shows how many minutes are left and what's been saved.

You can keep working. The card doesn't take over your keyboard.

The Mac turns off. Lifeboat can't prevent that, but by now your documents are saved and it knows what you had open.

If you'd rather the Mac hibernate than switch off, see Safe Landing below.

Next start3:04 PM

When you turn it back on

Plug in and start the Mac. Lifeboat opens a Welcome back window that lists what it can reopen: documents, apps, browser tabs, Finder windows, Terminal folders and the clipboard.

Untick anything you don't want back and click Restore Everything. Apps open, documents open as they were last saved, and windows go back to where they were. Anything that's already open is left as it is.

For now, windows come back on the desktop you're using, even if they were on another Space.

The Welcome back window: Your Mac ran out of battery at 2:31 PM, with documents, apps and tabs ticked and a Restore Everything button.

Fire Drill

A Fire Drill runs the 10% steps whenever you like. You'll see what Lifeboat saved and what it would reopen. Anything it couldn't handle is listed first.

Restart the Mac afterwards and you'll see the Welcome back window for real.

Fire Drill results: Lifeboat saved 2 documents and remembered 5 apps; Pages and Preview need you. The Run a Fire Drill dialog, listing the two TextEdit documents it will save.

Safe Landing (optional)

With Safe Landing on, Lifeboat hibernates the Mac at 3% instead of letting it switch off. When you start it again, everything is exactly where you left it, including unsaved work.

It's off to start with. To turn it on, run Test Safe Landing once, and it stays on only if the test works on your Mac. Saving and Welcome back work either way.

Settings, Safe Landing: passed on this Mac, Use Safe Landing switched on.

The rest of the time, Lifeboat is a battery menu. It shows the percentage and time left, and when you click it:

  • Temperature and powerHow warm the battery is and how many watts the Mac is drawing.
  • AdapterWhat's plugged in and how many watts it gives.
  • Low Power ModeA switch to turn it on or off.

You can change the 20%, 10% and 3% points in Settings.

Questions

Does Lifeboat stop my Mac from shutting down?

No. When the battery is empty, the Mac turns off. Lifeboat saves your documents and notes what's open before that happens, then offers to reopen everything when you start up again. If you turn on Safe Landing and it passes its test, Lifeboat hibernates the Mac instead.

Which apps can it save?

TextEdit, for now. Untitled TextEdit documents go into the Lifeboat Rescued folder in Documents. Pages, Numbers and Keynote are next. Apps that save as you type, like Notes, don't need it. For anything else, Lifeboat reminds you to save.

Whatever the app, Lifeboat still remembers its windows and reopens them.

What if I keep working after 10%?

Lifeboat saves again at 3% (or with 4 minutes left), and checks what you have open every minute until you plug in.

Does it restore windows on other desktops?

Not yet. Windows come back on the desktop you're using.

What permissions does it need?

Accessibility, to see your windows and where they are. Automation, for each app it saves documents in or reads tabs and folders from. Notifications, for the 20% and 10% alerts. It asks for all of these during setup, so you won't get a prompt at 10%.

Low Power Mode and Safe Landing also need a small helper, which macOS asks you to approve once.

Is it any use on a desktop Mac?

A little. Lifeboat checks what you have open every 10 minutes on any Mac, so after a power cut it can offer to reopen it. The 10% save is only for laptops.

What happens when the trial ends?

Lifeboat stops saving until you enter a license key. The battery menu keeps working, and anything it remembered during the trial can still be reopened. A license is $9 and covers 3 Macs.

Which Macs does it run on?

macOS 14 Sonoma or later, on Apple silicon or Intel.
