Get a head start on your native Mac app.
Red Screen App For Mac
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.
Tools and resources.
Download Xcode 12 and use these resources to build native Mac apps with Mac Catalyst.

Your Mac stuck on white screen and you desperately grab your phone to google solutions? As it mostly happens abruptly, you need to find the fast way to bring your Mac back to life. So, let’s get down to work right away!
Why my Mac stuck on white screen?
Macs are reliable computers, but on the rare occasions they may encounter trouble and won’t load. When this happens, you see a blank white screen, your Mac becomes pretty much unusable, and you keep asking yourself, “Why won’t my MacBook turn on?”
Usually, this happens after updating your operating system to a new version, when dealing with incompatible drivers, or if some applications fail to upgrade. This results in a blank screen on Mac until some steps are taken to bring your computer back to its normal state.
How to fix the MacBook white screen
Before you do anything to solve the Mac frozen screen, try an easy fix: check your peripherals. Try to disconnect all of them (printers, scanners, USB devices, etc.) with the exception of the keyboard and mouse. Then reboot your Mac. If it boots up now, one of those peripherals is the source of the plain white screen problem. However, if it fails and your MacBook won’t load, check out other possible ways to wake up your Mac.
1. Boot into safe mode
A safe boot feature in macOS and Mac OS X was designed for troubleshooting purposes. It allows to check the disk for all possible file system errors and if needed, a repair would be run. Starting your Mac in safe mode is the first thing you should do when your Mac won’t turn on.
To start up in safe mode:
- Press the power button, then immediately press and hold the Shift key.
- When you see the Apple logo, release the Shift key.
Once you boot using safe mode, the very first thing is deleting cache files. A cache is a place where data is stored temporarily to help things load faster. But eventually, files in a cache become outdated and start to pile up on your Mac, resulting in a white screen problem. Here’s a comprehensive guide “How to clear cache on a Mac.”
After you’ve deleted the cache files, you should also remove recently installed applications. But note that dragging them to the Trash is not the right way to remove apps as it leaves behind tons of associated files on your Mac. But don’t worry, there is a utility that will help you — CleanMyMac X. Its Uninstaller module is designed to uninstall apps completely, with no leftover parts and pieces behind.
Simply download the app (it’s free to try), launch it, choose Uninstaller and select the app you want to delete. Click Uninstall and the application will be removed completely. As simple as that!
As you’ve removed all the clutter, restart as normal without pressing any keys during startup. Export photos album mac. Probably you won’t see that MacBook white screen anymore.
2. Reset PRAM/NVRAM
PRAM/NVRAM is a small amount of memory that your Mac uses to store certain settings and access them quickly. These settings include sound volume, time zone, startup disk selection, and more. If you experience some issues related to these settings, resetting PRAM might fix your MacBook stuck on white screen.
Here’s how to reset PRAM/NVRAM:
- Shut down your Mac.
- Immediately press these four keys together: Command+Option+P+R.
- Hold down the keys until you hear the startup sound.
- Release the keys.

Disk Utility can fix several disk problems, including the white screen on Mac. That’s why use it to your advantage if the above steps didn’t work.

- Restart your Mac holding the Command and R keys.
- Release the keys when you see the Apple logo.
- Click Disk Utility and then click Continue.

4. Reinstall macOS
If all the approaches are failing and you still see that white screen on your Mac, you may need to reinstall your operating system. Don’t worry, it won’t affect your files, apps, user setting, etc. Only a fresh version of the macOS will be installed on your Mac again. Here’s how to do that for macOS Sierra, macOS High Sierra, macOS Mojave and macOS Catalina.

- Hold down the Command+Option+R keys until you see the Apple logo or a spinning globe.
- When startup is complete, you’ll see the Utilities window.
