Are there any other solutions?

Would that work on a Macbook Pro? I'm not extremely tech savvy and I don't wanna take risks when I'm not sure about what I'm doing.

I tried. I'm still stuck.

At the moment I'm logged in and I can see perfectly. I just can't do anything.

I tried to add an item called The Golden Bumper Car by using its id number. When I didn't see it I relogged. I still didn't have it so I tried to use the Red Racer instead. I used the id number and nothing. Then I tried to use the Better Clothes option in the help menu and now I'm stuck. I can't move talk use emotes or anything. What do I do?
