Immediately, the same problems!!! Cursor jumps a lot. The replaced the whole top part of the laptop - new keyboard trackpad battery. They kept it and sent back to Apple - or whoever they contract with. I was a little ticked I had just spend $3500 for a machine with these problems. But as soon as I got it home, same thing!! Took back to my local store a 2nd time.
1st time, they kept it like 5 days at my local Apple Store - didn’t even send off. My new MacBook Pro, 16-inch, spec’d out has been back to Apple 2x now. Seriously want to know why Apple made the trackpad so large. I’ve just now disabled “force click and haptic feedback”. Turning off “tap to click” did nothing for me. I have to “undo” the “changed text” and keep going. It also happens when I’m in Word typing documents. That was an excellent machine and never exhibited that kind of behavior in the same Outlook application. This new MBP is replacing a MBP from late 2014. Another odd occurence, is out of the blue, the current Outlook message would disappear (actually becomes a tab at the bottom of Outlook) and a new email would randomly open up.
Don’t know if there are some “propietary” shortcut/key combonations in Outlook, but yes, but insertion point would jump back a couple rows of text and/or delete entire sentences. it happened a lot for me in Microsoft Outlook when composing an email. The jumping cursor issue is happening right out of the box. I unfortunately got liquid on the keyboard last December and it died, so this is my only Mac. I had a 2012 mac with a new 2 TB Solid State drive-and had no trouble. I have no idea where the problem is, but we need to make more noise about this. In outlook, word, and websites, using chrome, safari, etc. Finally sent me a new MBP in May 2018, and the jumping around is still happening. Also, couldn't read my WD drives for MAC USB adapter not recognized MAC replaced the trackpad, all connections, everything. They then tried to tell me it was a problem with my apps or files were corrupted and so we reloaded everything from the original sources. First the geniuses said it was jumping around b/c I was touching the huge track pad, then they said it was the jewelry, I took everything off. I stopped using it and went back to my 2012 MBP. I had the same problem with the MAC from Sept. I know there's a dust issue with some keyboard people have had but this is more for typing and not a jumpy trackpad. Tell them to type on it until it happens to sounds like a bad trackpad to me, make sure they address the cables to and from the trackpad/keyboard too and not just the trackpad and keyboard themselves. demand they replace or fix it again, especially if it's under applecare warranty. THESE options are more for older macs as yours is basically brand new. If none of the above, you could open it and check the connection and make sure there's no corrosion or any moisture related anything on the plug in where the trackpad has it's connectors but if it's new and no liquid damage has ever occurred then this is prob not a cause but possible if it's even got wet too. Some can be adjusted VERY little but just enough (search here for this) But yes, it can be one of several y these first.they're the easiest. Could be several things, reset the PRAM.also check the cycles on the battery under system information/power if it's REALLY high like near 1000 it could be a bloated battery which pushes up on the trackpad and keyboard and causes this.also check the adjustment screw for the trackpad.
