MacOS – My MacBook Pro freezes if nothing is moving on the screen

hangmacbook promacos

My MacBook Pro (Retina, 13-inch, Late 2013) started freezing every time I boot it.

I've tried resetting the NVRAM and SMC, and have even reformatted it.

After doing that, I noticed that if I kept moving the mouse (trackpad or external mouse), my computer would no longer freeze. However, if I stopped moving the mouse, then the computer would freeze again.

The computer doesn't have this behavior if I start it in Safe Mode.

How might I troubleshoot this further?

Edit: When I was trying to copy the log from Console, I had to move the cursor or the computer would freeze. But after I open Safari, I could stop with no issue. I shift tabbed on Console and then the Mac froze again!

Edit 2: After some test, I figured out new strange behaviors. If something is moving on my screen, no freeze.

I was on Youtube, and I played a video > no freeze during the entire video. I stopped the video > freeze after 2s.

I tried something else: I launched another video then I minimized the window > freeze after 2s, but I could still hear the sound.

It's like the computer's freezing only if nothing is moving on the screen.

From your Console log, the last event before reboot was the
