Hi all. just want to know if there is anywhere where i can get them to replace the glass of my macbook pro, as the glass is cracked. i went to the apple service centre and asked if they could, but they still insisted on collecting 74.90 to run diagnostics. is that the normal practice? because i do not wish to pay 74.90 when all i want is for them to replace the glass. Thks in advance for your response
