This type of issue can happen on Windows systems due to virus infection.. I'm not familiar with Mac Systems but if you think this advice could help give it a try. The specific device driver gets infected and USB external input devices use a generic driver so that could explain why external input devices work. May 12, by Juan. I just runned into the same problem Jul 18, by Mauro.
Thanks, Myoungah - this fixed my current issue with the keyboard and also a months' long non-working trackpad. Apple Genius bar said I'd have to get a new module to fix that, but your solution fixed them both! Sep 9, by jztex. Show 11 more comments. Reece reecee. Replace the trackpad cable. This commonly goes bad on 13" models, and causes intermittent problems with both the keyboard and trackpad trackpad needs to be recognised in order for the keyboard to work on this model.
Thanks a lot I will try this but chow can I prevent this from happening one more time or what is the cause of the problem in the cable. Mar 5, by Ammar Falah. They do this since the cable is otherwise too long to fit along the top of the battery nicely. Not entirely sure though, this issue is very common but not spoken about often, since it causes issues with both the trackpad and keyboard, so people assume it is caused by liquid damage, when it isn't.
Mar 5, by Reece. Aug 1, by Wine Chit. You will have to find someone who can fix this in your area. It is a very easy repair, you just remove the bottom 10 screws, disconnect the battery, unscrew the 2 T5 screws for the trackpad cable shield, then remove the trackpad cable.
Aug 2, by Reece. The way the cable is bent at the trackpad end, is just dumb. It seems the cable is simply mm to long. I don't get it.. But I have experienced many week components in different macbook models. It always seems to be the same part that fails.

I don't have any Linux distros installed otherwise would have tried this. Nov 12, by Parth Gudhka. Hi Ruben, I am having exactly the same issue as you. When I boot with Ubuntu trackpad and keyboard works perfectly. When I reboot with High Sierra both the keyboard and trackpad not responding. I start to believe that the problem is with the ribbon like Axel is suggesting, however the fact that the keyboard and trackpad is working with Ubuntu is confusing me a little.
Jan 11, by andre bart. Trackpad and Keyboard have "legacy" usb interface which works in Linux. Apr 26, by inwerp. I've been researching this problem for a good year. I can use keyboard and touchpad in the Ubuntu dual boot and within the EFI boot menu boot holding Option key down. But in Mac OS, nada!! Sep 11, by Robert Vecino. Different OS's access the hardware differently! While we would assume it's software its not that simple!
Jan 11, by Dan. Axel Krottler naks. Posted: Nov 28, I had the same problem. It started when I forgot my charger at home and borrowed a MacBook Air charger. A day later the keyboard and trackpad had stopped working. I used an external keyboard and mouse until I have drained the battery.
I opened the computer and tried clicking the trackpad cable in place. A day later I got back my charger and the the keyboard and trackpad worked like a charm again. So I do not know it the problem was me charging the computer with the wrong cable or if the cable had been misplaced or a combination of the both. But now I have found the solution to my problem. I am pretty sure it is the trackpad connector that there is something wrong with. Disconnecting and reconnection the connector see step 17 in this guide: MacBook Pro 13" Retina Display Early Trackpad Replacement have fixed the problem.
I have also bought a new cable and will install that in my computer when it arrives. That's very interesting, because the same thing happened to me when I used a Macbook Air charger as well. Why would it cause this problem? Aug 26, by double dee. Basically the charger needs to tell the system what it is. If it fails to do that properly then the battery can be incorrectly charged which then can cause the battery to swell up pressing on the cable!
This is often a sigh the battery is do to be replaced. I would strongly recommend you install this gem of an app! CoconutBattery take a snapshot of the apps main window and post it here for us to see Adding images to an existing question in a fresh question so we can help you with your problem.
Posted: Apr 28, I had a similar problem and was trying to hard SMC reset by opening the Macbook pro and unplugging the battery. This did not help, but after trying this I unplugged the trackpad cable and keyboard cables then plugged them back and it worked! I suspect a loose connection with one of them. After reading these comments I switched my macbook off, turned it ovet and massaged the bottom with my palm couple of squeeky sounds.
Switched back and and voila! Full keyboard and trackpad functionality again! Aug 6, by steph. Lennard Schwarz. Posted: May 19, I would like to know if the trackpad still had its click response force touch or whatever you call it even though it didn't work? I ordered a replacement flex cable off of Amazon and after installing it my keyboard and trackpad are still unresponsive.
BUT when I click the trackpad, I don't even get a vibrating response telling me it registered my click. When I put the old cable in though, the trackpad and keyboard don't recognise any movement, but the trackpad recognise my clicks and gives a response by vibrating.
Yes the click response is a dome switch so you will feel it as it alters its state. Think how a you can click some bottle caps which make a sound this is the same effect here just smaller. Posted: Jul 8, Hey I am having a similar issue. My keyboard stopped working but my trackpad is still working fine. I took it to a repair place and they said that putting in a new keyboard did not fix the issue.
They now want to replace the logic part on the mother board and reprogram it. I told them that it could be the cable for the track pad and they said that when they swapped the mother board the keyboard worked fine so it has to be the mother board. When i plugged in an external keyboard, it also didn't work. Not sure what to do. More often than not, trackpad issues that aren't due to settings are caused by various hardware problems. They can originate either from the Mac itself or from user error.
If your pointer is jumping around the screen, there could be a range of non-serious causes—many of them down to simple human error. First, check your battery level. If it's low, plug in your machine and try again—it really could be that simple! Next, make sure that jewelry such as wedding rings and bracelets are not catching the pad as you work; they could cause the pad to read multiple signals at once and get confused.
Finally, make sure your fingertips aren't damp or sweaty. Trackpads and water don't mix well and can cause erratic behavior. Sometimes your trackpad works correctly, sometimes it acts up. Sometimes it lets you move the pointer, sometimes it doesn't. If this is the case for you, more often than not the problem is your MacBook's battery. Swelling and exploding MacBook batteries have been an issue in some older models.
Apple claims that it's expected behavior—which is highly dubious—but either way, its occurrence can impact your trackpad. Your first move should be contacting Apple support if your device is still under warranty or covered by AppleCare. If not, and you think you have the swollen battery issue, try taking the battery out and running your machine from mains power you can also pay someone to do this for you. You will almost certainly see a significant improvement.
Deleting them will force your Mac to recreate new ones. Note: Before proceeding, make sure you back up your Mac using Time Machine. Reboot your Mac, and see if this cured the problem. As a last resort, you can erase and restore your Mac to factory settings. If none of the above suggestions worked, you probably need to take your machine in for repair. There are lots of repair options available, but the exact route you should take depends on whether or not you have AppleCare.
Even if you do need a repair, there are still some workarounds that you can take in the meantime. The most obvious temporary solution is to disable your trackpad altogether and use a standard mouse. The process is simply the reverse of the previously mentioned troubleshooting tip. The Apple Magic Trackpad 2 performs exactly the same way as your MacBook's trackpad, except it's an external accessory that sits on your desk.
It's perfect if you're used to using the trackpad or if you're not a fan of Apple's Magic Mouse, and it's completely wireless too. Unfortunately, the external trackpad is not cheap, but it's your only option for a Mac-friendly external touchpad and it's better than the Magic Mouse.
We've covered Apple's support options in great detail before. Your only other option: try to fix your Mac yourself. There are lots of tutorials on YouTube, but some of the best repair guides are available on iFixit. Doing so will void your warranty. If your machine is still under warranty, you should let Apple do the work. Tampering with the lithium-ion battery in a Mac can also be very dangerous.
