![]() Warning: Mac power users only. Final Words Since it’s challenging to navigate to System Preferences without a mouse, he wrote an AppleScript that can help cure the macOS jumpy cursor and can toggle on and off the trackpad. Update Note: really appreciate one of our readers “Avery Ryder” for sending over this tip. But for those of you who don’t have a mouse or are used to relying on the trackpad for navigation, it can be troublesome.įrankly, I don’t know the cause (or reason) of this trackpad issue, I guess it has something to do with the hardware.įor example, it might be a sign that my trackpad could be failing soon and it’s best to have a holistic diagnosis. That means I can ONLY rely on the Apple Magic Mouse to navigate, which I’m okay with. I tried to uncheck that option above, and guess what…the trackpad problem appears AGAIN on my MacBook Pro. Now the erratic cursor jumping issue should disappear and you should be able to use your external mouse to navigate smoothly on your Mac. Step 1: On your Mac desktop, click the Apple logo, and select System Preferences. The Solution? It’s Actually Simple!Ĭheck an option called “Ignore built-in trackpad when mouse or wireless trackpad is present” via the System Preferences setting. The last thing I tried but didn’t work was performing software updates via Mac App Store.Īll these took me a few precious hours…until I finally fixed it with a simple trick. I also disconnected my Magic Mouse, and USB flash drive, and unplugged the charger. ![]() ![]() I also reset SMC and NVRAM on my MacBook Pro, thinking that would fix the issue as the symptoms I was facing were quite similar to what the Apple support articles describe.Īnd guess what? Nope, the Mac cursor still kept jumping and clicking and moving on its own after that. It turned out the main drive is working fine without any problems. I then suspected my Mac’s internal hard drive was malfunctioning, so I went ahead and pulled out Disk Utility and several other apps to check Mac hard drive health. Around 20 minutes later, no threats were found (to my surprise). So I immediately opened BitDefender Antivirus for Mac and ran a full scan. Although the erratic trackpad/cursor issue persisted at that time, I still could perform some basic operations though not that smoothly.Īt first, I thought my Mac was infected because the situation reminded me of viruses and malware issues back in the PC days.
