Go to System Preferences - Sound - Sound Effects. Toggle through the effects and make note of the sound that your mystery application is playing. When you find it go to the terminal and type: sudo fsusage grep 'aiff' Enter in the system password if asked. Wait for the sound to get played again and then look at the terminal output. This works in just about any version of OS X or macOS, as nearly as I can tell. Creating your own custom surround sound system in macOS is quick and easy (Image Credit: TPHeinz ) The Final Product.

macOS is very flexible when it comes to alerts. System Preferences allows us to choose on an app-by-app basis whether we want alerts that stay on the screen until dismissed, banners that display for a few seconds and then auto-dismiss, or no alerts at all.

We can choose whether or not apps play sounds. We can decide whether or not we want their alerts to show up in the Notification Center. And we can tell the Mac whether or not to add a badge to the app icon, for example to show how many unread emails we have.

So you might think that with all these different options at our disposal, there isn’t anything more that we could want. But there is just one more thing I want – and I want it rather a lot …

I cannot even begin to count the number of times I’ve been away from my Mac, heard an audible alert and then returned to the Mac to be unable to figure out where it came from.

Some alert sounds are sufficiently distinctive that we learn to recognize them. For example, if I hear a particular kerpling sound, then I know that probably means I have Facebook open in one of my tabs and I’ve just received a private message.

But other times, I hear a sound, return to my Mac and scan the screen without luck. There are no visible app badges in the dock. Nothing in Notification Center. Nothing I can identify as the source of the alert.

Indeed, there are even times when that happens while I’m actually using the Mac. Something pings or dings or rings or sings or plings or does some other kind of ing, and I can’t for the life of me work out what it was. Sometimes I spot it later, when I bring an app window to the foreground, other times it remains a mystery destined to remain unsolved until the end of time.

I do tend to have quite a lot of apps open at the same time. I could doubtlessly reduce the instances of these mystery alerts by closing those not actively in use, but with 16GB of RAM I find that everything I need sits happily running away, so it would be a bit of a nuisance to have to close and re-open those apps I use routinely.

So I’d like some way to simply ask my Mac what the most recent alert was. That could be as simple as adding a bell badge to the icon of any app that sounds an alert – though that wouldn’t help if it was a browser and you have a million tabs open. Perhaps ensure that anything that bleeps at you also has to add that alert to the Notification Center? Or maybe a menu bar bell with a drop-down?

Native Mac apps built with Mac Catalyst can share code with your iPad apps, and you can add more features just for Mac. In macOS Big Sur, you can create even more powerful versions of your apps and take advantage of every pixel on the screen by running them at native Mac resolution. Apps built with Mac Catalyst can now be fully controlled using just the keyboard, access more iOS frameworks, and take advantage of the all-new look of macOS Big Sur. There’s never been a better time to turn your iPad app into a powerful Mac app.

Designed for macOS Big Sur.

When an app built with Mac Catalyst runs on macOS Big Sur, it automatically adopts the new design. The new Maps and Messages apps were built with the latest version of Mac Catalyst.

Get a head start on your native Mac app.

Your iPad app can be made into an excellent Mac app. Now’s the perfect time to bring your app to life on Mac. The latest version of Xcode 12 is all you need. Begin by selecting the “Mac” checkbox in the project settings of your existing iPad app to create a native Mac app that you can enhance further. Your Mac and iPad apps share the same project and source code, making it easy to make changes in one place.

Optimize your interface for Mac.

Your newly created Mac app runs natively, utilizing the same frameworks, resources, and runtime environment as apps built just for Mac. Fundamental Mac desktop and windowing features are added, and touch controls are adapted to the keyboard and mouse. By default, your app will scale to match the iPad’s resolution. On macOS Big Sur, you can choose “Optimize interface for Mac” to use the Mac idiom, running your app using the native resolution on Mac. This gives you full control of every pixel on the screen and allows your app to adopt more controls specific to Mac, such as pull-down menus and checkboxes.

Even more powerful.

The new APIs and behaviors in macOS Big Sur let you create even more powerful Mac apps. Apps can now be fully controlled using just the keyboard. You can create out-of-window and detachable popovers, control window tabbing using new window APIs, and make it easier for users to select photos in your app by using the updated Photos picker. iOS Photos editing extensions can now be built to run on Mac. And your app is even easier to manage when it’s running in the background with improved app lifecycle APIs.

New and updated frameworks.

Mac Catalyst adds support for new and updated frameworks to extend what your apps can do on Mac. HomeKit support means home automation apps can run alongside the Home app on Mac. The addition of the ClassKit framework lets Mac apps track assignments and share progress with teachers and students. Plus, there are updates to many existing frameworks, including Accounts, Contacts, Core Audio, GameKit, MediaPlayer, PassKit, and StoreKit.
