Hello, I have been trying to install 1.12.2 forge for a while now, but every time I click install client, it starts up but then stops a little before half way through. I was waiting and waiting so i did something else. I cam back an hour later and it was still at the same spot and I have been trying to do it forever. Do you think this can be fixed??? Also I have been trying to do this on a mac. Not sure if that affects anything.
