It’s frustrated to see the cursor frozen, even though it looks like a rainbow ball. In such cases, we can’t point keys on the screen or indicate the position. So if your cursor often gets froze or jumps randomly, it’s time to learn solutions and fix it on your Mac.
Was it frozen after you open some app? If so, you may rectify the problem by closing the app. The question would be: how to close it when you are not even able to move the cursor at all?
Well, just do it through the short cut keys by simply pressing Command + Option + Esc keys at once, then you shall see the pop-up pane. Now highlight the app that you think caused your cursor to freeze, and click on Force Quit.
In case you have opened too many apps or tabs on the web browser, which can make your Mac run out of memory and freeze your cursor, try to “hit the target” more accurately:
Press Command + Space keys on at once to access Spotlight, and type in activity monitor and click on the result to open it. Then you can double-click the unresponsive process that is shown to eat up too much memory, and click Quit.
This should be the simplest way. Many users don’t bother to restart their computers and haven’t done it for long. Before doing this, disconnect all accessories from your Mac. If the cursor gets frozen and you are unable to power off your Mac, just press and hold the power button for a few seconds.
If it is a MacBook you are using and you only use the trackpad to navigate it, you should clean it from dust termly, and better ensure your fingers are clean and dry when using it. To do this, you need to first unplug your MacBook from the adapter and power if off. Rather than directly spraying the cleaning to the trackpad, you need a microfiber or lint-free cloth.
