I've searched and noticed other people having the same issue but no fixes.
Recently my trackpad stopped working which resulted in me changing it.
Worked fine for months. All of a sudden my trackpad left-click stops working and even if I plug in a mouse, it doesn't work, but the right click on the plug-in mouse works fine.
The left click works fine in Diagnostics mode, works every time. But works nowhere else.
I thought I would reinstall the OS to see if that would fix it.... but now I cannot install the OS as I get stuck on the page where you have to click the Hard drive and press next, can't seem to do that with the keyboard only.
Any suggestions? Need to work from home and can't get it working. Model A1502 Macbook pro Thank you.
