“Hey! I have tried all your methods and nothing seems to work. When I shutdown my laptop there graphics go to normal for a split second. Unfortunately it's still glitched. Do you have anything else in mind?”

Take this in for service…

Making a Store Appointment:

Set up a Genius Bar Appointment at your local Apple Store. There, it will be diagnosed, and you'll be provided with your options. IMPORTANT: Be certain to bring along a proof of purchase (i.e. sale receipt or original packaging) and the Mac, itself.

Based on personal experience...

About a Flickering Mac Screen:

During the days of COVID, Apple sold me a 2018 MBP and after installing macOS 13.4 update, my screen flickered, but never when it went close to closing the screen. It was during the days of COVID, and, as a result, had to send it in 11 times to get this fixed. I spoke with them every single day. Being so patient of a customer, they provided me a free upgraded mad, for no more than the price of the coverage. I’ve had it ever since, and only had thel issue once, when opening it as a new device. The culprit ended being the connection going from the screen into the LogicBoard. It just became loose, presumed a factory failure.

Distorted Screen After Zoom Install:

A. Viewing and Deleting Login Items:

Go To: System Preferences > Users & Groups > Click your Username > Login Items> Rid of Items that are Not Needed

B. What to do In Safe Mode:

Se if the screen is any different, and see what happens when you restart this.

C. How to Add a User:

Go Here: Add a user or group on Mac - Apple Support

Then, login, and see if it as any different. If so, then it is a misconfiguration issue in your original user. If not, then it is an issue with the entire macOS.

What else to try...

D. Reset the SMC and your NVRAM:

(Applies to Intel-Based Macs Only): Sometimes when changes are made to the system(i.e. Updates), system configurations (i.e. for Power) become manipulated, technically. So, reset the SMC and NVRAM. Try performing each thrice. It may take sometime. So, be certain you have the time to perform these resets.

Distorted Screen After Zoom Install:

Take Screenshot:

Is this just the login screen? Or is it your entire computer? Take a screenshot of both screens, and then see what happens when you open them. Open them on another device by eMailing them yo yourself and download them. If they look the same, then it is an error in the operating system. If they look normal, then it is a hardware issue. See here: Take a Screenshot On your Mac - Apple Support

"Macbook glitched: I ran an Apple diagnostic for hardware issues and nothing was found. I took screen shots and it showed up normal on my phone."

Getting Instal a macOS After Migration:

A. Reinstall the macOS:

• Nothing would be deleted. It's just that items that have become corrupted or deleted, would be replaced or reinstalled back to where they should be. Go Here: How to reinstall macOS from macOS Recovery - Apple Support.
• Important: Be certain to create a backup of your Mac prior to all of this. That way, you can have something to restore from the Mac from, should anything go wrong with the reinstall.

B. Restore from a Backup:

Be sure you back up your Mac with Time Machine, prior to performing any major change, such as this. That way you will have something to restore your Mac from, should anything go wrong afterwards. So, if you have a backup, then you can restore from it. But, items would be lost if you restore to a backup that does not have the currently-installed items on it.

As a last resort...

C. Reinstalling the macOS Anew:

View my User Tip: How to Reinstall the macOS Anew - No TMB Prior to Upgrade - User Tip. Format the hard drive with Sanoma on step D.

In Depth:

Pretty much, it is a matter of:

1. Erasing: and formatting your hard drive to APFS
2. Installing: [the applicable macOS] via a USB Bootable Installer
3. Restoring: info from a Time Machine Backup, using Migration Assistant
