MacBook get crashed after installing Muse

After installing Muse on my MacBook, my system got crashed. It might sound weird but that’s true. It’s just six months I bought it. I was panicking meanwhile one of my friends called a technician from MacBook Repair Dubai. He was so efficient at his work that within a span of a few hours he just fix the issue. He didn’t even charge much high. I got very quick service. Really thankful to him.
