When the rainbow ball icon pops up and spins on the Mac screen, it is a sign that the computer is hanging. Here are some ways that Apple offers to deal with when the Mac crashes.
Steps
Fixing a Mac that hangs

Force shutdown of suspended programs. If a program crashes but the computer is still responding, you can force close the program and continue using it. There are several ways to force shutdown a suspended program:
- Click on the desktop or any open window to redirect away from the suspended application. Click the Apple menu and choose “Force Quit”. Highlight the program that is hanging and click “Force Quit” to close.
- Press ⌘ Command + ⌥ Option + Esc to open the Force Quit menu. Select the suspended program and click “Force Quit”.
- Hold down ⌥ Option , Ctrl and at the same time click the application icon in the Dock. Select “Force Quit” from the menu.

Restart your Mac when it crashes. If the system becomes unresponsive, or you cannot open any of the Force Quit menus, force the computer to restart. There are ways to force restart your Mac, even if you can’t move the mouse pointer. [1] X Research Source
- Press ⌘ Command + Ctrl + ⏏ Eject to force the computer to restart. The ⏏ Eject key is usually located in the upper right corner of the keyboard. Newer MacBooks usually don’t have the ⏏ Eject key.
- If the key combination doesn’t work (or your Mac doesn’t have the ⏏ Eject key, you can hold down the power key for about 5 seconds to force shut down the computer.The power button is in the upper-right corner of the keyboard, or behind the iMac, and other desktops.
Fix the cause

Determine if the problem lies with the program or the operating system. If this only happens every time you run a particular program, chances are the problem lies with that program. If your Mac just hangs randomly, or when you’re performing everyday tasks on it, it’s probably an operating system problem. If the computer crashes when you are connecting to an external device such as a printer or USB, it is likely that the error is caused by the device. Once you have an overview of the cause, it will be easier for you to fix the problem.

Check free memory. The system becomes unstable when the machine’s boot drive runs out of memory. The boot drive (the drive containing the operating system files) should usually have at least 10 GB of free space. If the current memory is less, it is possible that the computer will start to fail. [2] X Research Source
- The fastest way to check available storage is to click the Apple menu and select “About This Mac”. Click on the “Storage” tab to see used and remaining space. If the drive has less than 10 GB available, you need to delete some unnecessary files or programs.

Update apps and operating systems. The crash you’re experiencing is likely a known bug and fixed in a recent version of the program or the OS X operating system. Updating the software may fix the problem.
- Click the Apple menu and select “Software Update”. Download and install available updates. This tool will find and install updates for the operating system and applications that have been installed through the Mac App Store.
- Update apps outside the App Store separately. If you installed the program from a source other than the App Store, run the Update tool for each program, or install the latest version from the website.

Disconnect all peripherals. Sometimes errors in the device can cause the computer to hang. Disconnect all peripherals such as printers, scanners, external hard drives or USBs.
- Reconnect each device and check if it crashes or not. This process will help you determine which device the problem lies.
- Once you’ve identified the device that’s causing your computer to hang, look online to see if anyone else has had the same problem as you, and if the manufacturer has released any patches.

Perform a safe boot process (Safe Boot). If none of the steps in the article fixed your crash, try the safe boot process. This process will run only the critical files that OS X needs to launch, and automatically run many troubleshooting scripts. [3] X Research Sources
- To start Safe Boot, you need to restart your Mac and hold down the ⇧ Shift key as soon as the boot sound plays. Safe Boot mode will be loaded. If your Mac restarts on its own while it’s in Safe Boot, you don’t need to worry because your computer is trying to fix a problem with the boot drive.
- If your Mac still crashes while in Safe Boot mode, restart the computer as usual to see if the error has been fixed.

Repair the boot drive in recovery mode. If the boot drive has problems, you can fix it by using the Disk Utility utility in Recovery Mode. [4] X Research Sources
- Restart the computer and hold down ⌘ Command + R during the boot process.
- Select “Recovery HD” from the menu that appears.
- Select the “Disk Utility” option.
- Select the drive for which you want to check for errors and click the “Repair” or “First Aid” tab.
- Click “Repair Disk” to start scanning for errors. If it detects a problem, Disk Utility will try to fix it on its own. This process may take a while to complete.
