My Mac boot very slow during progress bar

Hey there yosiajoe,

Thanks for reaching out to the Apple Support Communities. Just to confirm, is your MacBook only showing a progress bar when trying to start up? If so, check out the steps in the following resource that can help: If your Mac starts up to an Apple logo or progress bar - Apple Support

If your Mac is stuck on this screen or keeps restarting

If startup never progresses beyond an Apple logo or progress bar:

1. Press and hold the power button on your Mac for up to 10 seconds, until your Mac turns off.

Every Mac has a power button. On laptop computers that have Touch ID, press and hold Touch ID.

2. Turn your Mac back on. 

3. If the issue persists, press and hold the power button until your Mac turns off. Then unplug all nonessential accessories from your Mac, including printers, drives, and USB hubs. You could have an issue with one or more of those devices or their cables. 

4. Turn your Mac back on.

5. If the issue persists, once again press and hold the power button until your Mac turns off. 

6. Repair your startup disk as described in How to repair a Mac disk with Disk Utility.

7. If the issue persists, reinstall macOS from macOS Recovery.

If still having issues after the steps above, then we'd recommend reaching out to Apple Support directly from this link here: Get Support - Apple

If experiencing a different issue, provide us with more details on what you're seeing, and we'll continue from there.

Have a great day!
