O guia está perfeito. Consegui, só seguindo as instruções, trocar a bateria do meu MacBook. Minha única dificuldade foi descolar a bateria antiga, pois eu não tinha o líquido removedor de adesivos nem o iOpener. Utilizei duas pequenas espátulas de plástico e, com muito trabalho, fui soltando a cola. Parabéns pelo ótimo guia!

The guide is perfect. I was able to replace the battery in my MacBook by following the instructions. My only difficulty was removing the old battery, as I didn't have the adhesive remover or the iOpener. I used two small plastic spatulas and, with a lot of effort, I managed to loosen the glue. Congratulations on the great guide!

I have model N4050, so slightly different positions for screw and HDD but, success! New SSD, clone of system, in place and working fine! Thank you very much for the nice work!
