A boot loop issue in macOS is when your Mac keeps restarting without reaching the login screen. This can be frustrating and prevent you from accessing your files and apps. Fortunately, there are some ways to fix this problem and restore your Mac to normal. Here are some steps you can try to resolve a boot loop issue in macOS.
The first thing you should do is make sure your Mac has enough power to boot up properly. If you are using a laptop, plug it into a wall outlet and let it charge for a few minutes. If you are using a desktop, check the power cord and the outlet for any damage or loose connections. Sometimes, a low battery or a faulty power supply can cause a boot loop issue in macOS.
To troubleshoot a boot loop issue on macOS, boot into Safe Mode, reset NVRAM/PRAM, run First Aid in Disk Utility, reinstall macOS without affecting data, boot from a different disk, check for software updates, disconnect external devices, reset SMC, and contact Apple Support if none work. Back up data and consider using recovery tools if necessary.
The next step is to boot your Mac into safe mode, which is a diagnostic mode that loads only the essential system files and disables some features. This can help you identify and fix any software issues that might be causing a boot loop issue in macOS. To boot into safe mode, hold down the Shift key while you turn on your Mac and release it when you see the Apple logo. If your Mac boots into safe mode successfully, you can try to repair the disk, update the system, or remove any incompatible or corrupted apps or files.
If safe mode does not work, you can try to reset the NVRAM and SMC, which are two components that store some settings and data related to the boot process, power management, and hardware functionality. Sometimes, these settings can get corrupted or out of sync and cause a boot loop issue in macOS. To reset the NVRAM, hold down the Option, Command, P, and R keys while you turn on your Mac and release them after you hear the startup sound or see the Apple logo twice. To reset the SMC, follow the instructions for your Mac model on Apple's support website.
The last resort is to reinstall macOS, which will erase your Mac's hard drive and install a fresh copy of the operating system. This can fix any system files or settings that might be damaged or missing and cause a boot loop issue in macOS. However, this will also delete all your personal data and apps, so you should back up your files before you proceed. To reinstall macOS, hold down the Command and R keys while you turn on your Mac and release them when you see the Apple logo. This will launch the recovery mode, where you can choose to reinstall macOS from the menu.
A boot loop issue in macOS can be annoying and disruptive, but it does not mean your Mac is broken. By following these steps, you can troubleshoot and fix the problem and get your Mac back to normal.
