This is a stupid question but I have a 820-00165 that boots to the OS but strangely loses the trackpad at the login
screen.
I was trying to install OS X Catalina on a repaired machine off a USB drive installer that I have used many times.
The trackpad works at this point. Its when I get to the language INSTALL screen (i.e where you pick the language to proceed with the install)
that the cursor freezes in the upper left hand corner of the screen.
I inspected the trackpad cable and it not good so I replaced it.
Same issue.
I am now US cleaning the board as the connector may have some debris in it.
My question:
Why does the trackpad work when the machine first starts (power button + option key pressed) and USB drive in place, but stop working when it gets to the language select screen on the Catalina install. I was hesitant to even post this as I though it was surely a software issue that I was dealing with such as an install issue but
I think it is a hardware issue and the trackpad connector is to blame.
