Mac Boot loop issue, showing a Flashing folder or questions mark? Here is how to fix in June 2023

If your Mac is stuck in a boot loop and not starting up properly, it could be due to various reasons. To troubleshoot the issue, you can try the following steps:


  1. 1. Safe Boot: Start your Mac in Safe Mode by pressing and holding the Shift key immediately after turning it on. Safe Boot performs a check of your startup disk and loads only essential system files. If your Mac starts up successfully in Safe Mode, it may indicate that there is a software conflict or an issue with a login item or startup item.

  2. Reset NVRAM/PRAM: Resetting the NVRAM (non-volatile random-access memory) or PRAM (parameter random-access memory) can sometimes resolve boot-related problems. To reset the NVRAM/PRAM, restart your Mac and immediately press and hold the Option, Command, P, and R keys together. Hold them until your Mac restarts again and you hear the startup sound for the second time.

  3. Disk Utility: Boot your Mac into Recovery Mode by restarting and holding down Command + R until the Apple logo appears. Once in Recovery Mode, select "Disk Utility" from the macOS Utilities window. Use Disk Utility to repair the disk permissions or run First Aid to check and repair any disk errors.

  4. Reinstall macOS: If none of the above steps resolve the issue, you may need to reinstall macOS. In Recovery Mode, select "Reinstall macOS" or "Reinstall OS X" and follow the on-screen instructions to reinstall the operating system. This process usually keeps your files and applications intact, but it's always a good idea to have a backup before proceeding.

  5. Hardware issues: If the boot loop issue persists even after reinstalling macOS, it could be a hardware problem. In such cases, it's best to contact MacBook Repair Vancouver or visit the nearest Computer Repair Centre for further assistance.

  6. Certainly! Another potential reason for a Mac not booting up properly or getting stuck in a boot loop could be insufficient disk space during the operating system installation. When installing a new version of macOS, the installation process requires a certain amount of free disk space to complete successfully.


If your Mac doesn't have enough available disk space during the installation, it can lead to errors or incomplete installation, causing boot issues. To address this problem, you can try the following steps:

  1. Free up disk space: Delete unnecessary files and applications to create more space on your startup disk. You can use the built-in macOS storage management tools or third-party applications to identify and remove large or unnecessary files.

  2. External storage: If you can't free up enough space on your Mac's internal drive, consider using an external storage device. Connect an external hard drive or USB flash drive with sufficient space to your Mac and select it as the destination for the macOS installation. This allows the installation process to proceed without disk space limitations.

  3. Clean install: Instead of upgrading the operating system, perform a clean installation of macOS. This involves erasing the entire startup disk and installing a fresh copy of the operating system. Before proceeding with a clean install, ensure you have a backup of your important files, as this process will erase all data on the startup disk.

If lack of disk space during installation is the cause of the boot loop, addressing the storage issue should resolve the problem. However, if the boot loop persists or you encounter other errors, it's advisable to seek assistance from MacBook Repair Vancouver at 604-653-6591 or BC Computers Repair Centre at 604-200-2995 for further troubleshooting and guidance.
