It seems the only solution to make it work again is to hold the power button to reboot. If you were watching a video, horizontal lines cut through the screen. One second your MacBook is working perfectly fine, the other second everything just hangs up - the cursor won’t move. Scenario 3: MacBook Pro keeps freezing randomlyĭetails: Your Mac just freezes without any signs and it happens every few hours or days.

A working solution is: first upgrade your MacBook to an ealier version, then update to the latest version. Note: if this happens while you’re updating to latest macOS, the progress bar keeps hanging at 99% (or only one minute remaining), you’ll have to quit the update. Clean up your MacBook hard drive and fix potential disk errors - you can do this quickly using CleanMyMac.Press the power button for 3-5 seconds to force a shut-down of the computer. Reasons: It happens on rare occasions, but the issue could result from over-used system resources, MacBook Pro uptime too long, hard disk errors, etc. Sometimes you also hear the loud noise coming from the fan (if you are using an old MacBook with an HDD inside). You are unable to use the keyboard to type, the mouse cursor is unable to move as you want, the same screen seems just hang there for good. Scenario 2: macOS totally freezes (you can’t move cursor)ĭetails: the whole system becomes completely unresponsive. Warning: a force quit on a running Mac application may cause you to lose any content that hasn’t been saved. You can also press “Command + Option + Esc”, it does the same thing.

Then highlight the unresponsive app, and click “Force Quit” to exit. To do so, go to the Apple logo on the top left corner, click on it and select the “Force Quit” option. It may become responsive again (hopefully). If you haven’t saved your work, wait for a few minutes.Reasons: the app may be waiting for other hardware resources to become available, or the software may have a bug that drops itself into a calculation loop. The application won’t respond to any commands. When you click around, the app just hangs with the cursor spinning like a pinwheel. For example, Adobe Photoshop, iMovie, or sometimes the web browser you use Safari. Scenario 1: An app is frozen (you can move cursor)ĭetails: this kind of apps usually demand a lot of system resources to process. Scenario 4: Mac cursor freezes while opening a specific app.Scenario 3: MacBook Pro keeps freezing randomly.Scenario 2: macOS totally freezes (you can’t move cursor).
