    Hi Hulk2k,

    Thanks for using the Apple Support Communities. We're sorry to hear that you are having these issues with your MacBook Air after a recent upgrade. If you are seeing flickering of your home screen/desktop, you may want to try booting in safe mode and see if the issue persists. If it does, try to note exactly when it starts happening (immediately when the screen comes on, at the login screen, as the desktop is loading, etc). You may find the information and steps outlined in the following article helpful.

    Hi Hulk2k,

    Thanks for trying that. Just to clarify, when you say that it happens just after loading the startup screen for the desktop, which exact screen are you talking about, and/or what exactly are you seeing? Did you see the Login screen, and was there flickering there? You may find the following article helpful:

    Also, when you say that it shows flicker for 2 seconds, do you mean that it flickers for two seconds and then goes away and doesn't come back, or do you mean that it flickers every two seconds consistently? 

    Another thing you can do to try and isolate this issue would be to test in a new user. You may find the information and steps outlined in this article helpful:

    Hi,

     

    Thanks tons for your efforts, I wish I can upload Video content to help you understand better but the option is not available, somehow I have managed to take a pictures, during making video of the situation happens to me every time i logged in

    1. I have tried log in Safe Mode still it shows the same flicking, even more screen flickers when I tried to open a web site

    2. I have tried making new user account, and the same thing happens to it

    3. First picture you see account is loading,second is flickering, this is just at the moment I captured anyways it last for 2 to 3 seconds, same on the New User and take more time in Safe Mode. I hope you understand now
