Safe to Quit sits in your menu bar and watches for the one app causing it. It tells you in plain English, then asks a single question: close it, or keep it?
Pay once. No subscription.
macOS 13 or later.
Sound familiar?
Every card below is a real screenshot of Safe to Quit. This is exactly what shows up in your menu bar.
Something is working your Mac flat out, and you can't see what. Safe to Quit names the app, says how long it has been going, and asks if you want to close it so your Mac can cool down.
If nothing unusual is running, it says so too, and points you to the usual suspects: a warm room or blocked vents.
Some apps take a little more memory every minute and never give it back. You don't notice until the whole Mac drags. Safe to Quit spots the one that keeps growing, long before you'd work it out.
Closing works like choosing Quit yourself, so the app asks you to save anything that's open.
A download, a Terminal command or a video call left open can keep a Mac awake for hours, running warm and using power. Each morning Safe to Quit tells you if your Mac slept, and what kept it up. It can warn you at bedtime next time.
This one is from our own Mac. A Terminal command kept it awake for 10 hours.
Dozens of tabs add up. When one app holds a big share of your Mac's memory, Safe to Quit tells you how much, in plain words, before everything else starts to slow down.
Tap "Keep" and it won't ask about that app again today.
Safe to Quit lists what's using your Mac right now, biggest first. Apps you can close get a Quit button and one "Quit it?" check. Parts of macOS are labelled "Part of macOS" and left alone, so you can't break anything.
It knows 369 parts of macOS by name and explains each in one plain sentence, like "Spotlight is sorting your files so search is fast. It stops on its own."
How it works
From your menu bar, every few seconds, using under 1% of your Mac's power. It learns what's normal for each of your apps, so a video app that's always busy won't nag you.
When something is unusual, it opens with the answer: which app, what it's doing, and why that makes your Mac warm, loud or slow. No charts, no jargon.
One yes or no question with two buttons. "Close" asks the app to quit normally. "Keep" means it won't bring that up again today. You're always the one who decides.
Open it any time for a calm answer: is your Mac hot, and is memory getting full? When everything is fine, it simply says so.
Want a tap on the shoulder? Turn on notifications and it asks the same yes or no question in a normal Mac notification. At most three a day, only for things that matter, and never between 10 PM and 8 AM.
What it will never do
Closing works exactly like choosing Quit yourself. Apps get to ask you to save your work.
Parts of macOS are explained, never closed. It can't delete, clean or change anything.
Nothing about your Mac is sent anywhere. The only thing it ever asks the internet is whether a newer version exists.
Pay once and it's yours. No sign-up, no login, no monthly bill.
What you get
Light or dark, it matches your Mac. Settings fits on one small screen, on purpose.
Pricing
The price goes up as more people buy. The first 100 get it for $5.
Why does the price go up? Early buyers take a chance on a new app, so they pay the least. The counter above comes from real sales and moves by itself.
No. That's the whole point. You never see words like "process" or "CPU". It says things like "Video Export is working your Mac hard" and gives you two buttons.
No. It only ever asks apps to quit the normal way, the same as choosing Quit from the app's menu, and only after you say yes. It never force quits, never touches parts of macOS, and never deletes or cleans anything.
It uses under 1% of your Mac's power while it watches. It's a small native Mac app, about 2 MB to download.
Macs with macOS 13 Ventura or later, with Apple silicon or Intel. On most Apple silicon Macs it also shows the temperature. Where a Mac doesn't share that, it still warns you when your Mac is hot, using macOS's own heat signal.
No. Everything it notices stays on your Mac. Once a day it checks safetoquit.com for a newer version number, and that request carries nothing about you or your Mac. You can turn that off in Settings.
You'll see a download button straight away, and the same link arrives by email. Open the file, drag Safe to Quit into Applications, and open it. It appears in your menu bar at the top right. Lost the email? Get your link again.
Reply to your receipt email within 14 days and you'll get a full refund.
Next time it's hot, loud or slow, the answer is one click away in your menu bar.
