Question 1

Why does macOS reset my default apps?

Accepted Answer

macOS occasionally has problems permanently saving third-party apps as default. This is especially common after full restarts – when the Mac was shut down and boots up again – causing the system to revert to Safari and Apple Mail. Waking from standby or sleep mode usually does not trigger this. Intentional or not – annoying either way. DefaultBrowserGuard monitors this setting and warns you immediately.

Question 2

What does DefaultBrowserGuard cost?

Accepted Answer

DefaultBrowserGuard is currently 100% free to use. There are no hidden subscriptions or in-app purchases.If you like the app, feel free to voluntarily give me a small tip via Buy Me a Coffee.

Question 3

Does the app slow down my Mac?

Accepted Answer

No. The app is extremely lightweight and consumes virtually no CPU or RAM resources. It runs unobtrusively in the background in your menu bar.

Question 4

Which macOS versions are supported?

Accepted Answer

DefaultBrowserGuard requires macOS 14.6 or newer and runs natively on Apple Silicon (M1-M5) as well as Intel Macs.

Question 5

What happens to my data?

Accepted Answer

Your privacy is important to us. DefaultBrowserGuard only collects completely anonymous, non-traceable analytics data via aptabase.com to improve the app. No personal data, IP addresses or content is collected.

Question 6

Does it work with my browser / email client?

Accepted Answer

Very likely. We support Safari, Chrome, Firefox, Edge, Brave, Arc, Opera, Vivaldi, DuckDuckGo, Orion as well as Apple Mail, Outlook, Thunderbird, Betterbird, Spark, Airmail, Canary Mail, Mimestream and many more. See compatibility.

Question 7

Why isn't the app on the App Store?

Accepted Answer

Sometimes the best things need their own path. A direct download gives us more freedom for updates, features, and fair pricing – and gives you full control over your software.

Question 8

How do I change the default browser on Mac?

Accepted Answer

Open System Settings and go to "Desktop & Dock" → "Default web browser". There you select your preferred browser. Problem: macOS often resets this setting back to Safari after restarts or updates.

Question 9

How do I change the default email client on Mac?

Accepted Answer

To change the default email client, you must open the Apple Mail app, then go to Settings → General and select your desired client (e.g. Thunderbird or Betterbird) under "Default email reader". Yes, even if you don't want to use Apple Mail, you have to open the app for this. Or simply use DefaultBrowserGuard and change the default email client centrally with one click.

Question 10

Why does Safari keep becoming my default browser?

Accepted Answer

macOS frequently resets the default browser back to Safari after full restarts or system updates. This is a long-known problem that especially annoys Chrome, Firefox, and Brave users. DefaultBrowserGuard monitors your setting and automatically restores it.

Question 11

How do I set Thunderbird or Betterbird as my default email client?

Accepted Answer

Open the Apple Mail app → Settings → General → "Default email reader" and select Thunderbird or Betterbird. Unfortunately, macOS regularly resets this setting back to Apple Mail after restarts. DefaultBrowserGuard keeps your choice permanently and warns you of any changes.

Question 12

Are default apps reset after a macOS update?

Accepted Answer

Yes, unfortunately this is a common problem. Many users report that after every macOS update, Safari is set as the default browser and Apple Mail as the default email client again – without warning and without asking.

Question 13

What to do when Chrome is no longer the default browser?

Accepted Answer

Go to System Settings → "Desktop & Dock" → "Default web browser" and select Chrome again. So you don't have to repeat this after every restart, DefaultBrowserGuard monitors your setting and automatically restores Chrome.

Question 14

Do I need DefaultBrowserGuard for Arc, Brave, or Opera?

Accepted Answer

Yes, all browsers are affected – whether Chrome, Firefox, Edge, Brave, Arc, Opera, or Vivaldi. As soon as it's not an Apple-owned browser, macOS can reset the setting after restarts or updates.

Question 15

Why does macOS show a warning when opening the app?

Accepted Answer

macOS Gatekeeper blocks apps without a paid Apple signature. This is a standard security feature, not a malware warning. A single click on "Open" in the dialog or a quick Terminal command is enough.

Question 16

Is the app really safe if it's not signed?

Accepted Answer

Yes. "Not signed" simply means there is no paid Apple Developer certificate – it does not mean the app is harmful. DefaultBrowserGuard runs exclusively locally on your Mac.

Question 17

What does "unidentified developer" mean?

Accepted Answer

This is the standard macOS label for all apps that were not signed through the paid Apple Developer Program. Think of it as a missing stamp, not a danger.

Question 18

Do I have to repeat the Terminal command after every update?

Accepted Answer

Yes. Every time a new version is downloaded, macOS re-marks the file with the quarantine flag. The command must therefore be run once per download.

Question 19

Can I open the app without the Terminal?

Accepted Answer

Yes – on older macOS versions, a right-click (or Ctrl+click) on the app → "Open" is enough. The dialog will then show an "Open" button despite the warning. Starting with macOS Sequoia, this sometimes no longer works, leaving only the Terminal command.

Question 20

Why is the app not on the Mac App Store?

Accepted Answer

Two reasons: First, the App Store requires the paid Apple Developer Membership (~99 USD/year). Second, the App Store requires sandboxing – a system utility like DefaultBrowserGuard, which needs to change default apps, would not work there.
