Hi Trackpad not working - A1502 13’ late 2013 I just want to know if this will also affect the keyboard, because I seem to be having keyboard issues as well. The keyboard freezes for 0.5 seconds time and again. Not sure if this might be related to the faulty trackpad. Planning on replacing the trackpad soon.

This is actually a very common issue on the A1502 Late 2015 models where the trackpad cable goes over the battery and rubs against the back case causing it to go bad. Can you confirm your MacBook Pro Retina is not the Late 2015 model by inputting the serial number of your mac here on this linked webpage? https://everymac.com/ultimate-mac-lookup

This can be caused by a virus. Get a good “Paid For” virus protection program such a Symantec Endpoint Protection. https://www.symantec.com/products/endpoi… I have fixed three MBPs in the last month by removing virus.
