Wow! I just got a used Macbook Pro 15 inch. MINT CONDITION and nearly maxed out specs. I love this thing. I found out the left speaker is either blown or malfunctioned. I read where SO many people were having the same problems. I contacted apple and have an appointment tonight but I know what they are going to tell me : "The warranty is expired and we can help you for $500" So, anything that I could tell them that would raise my chances at getting it fixed? I remember my 2016 macbook pro had issues with the keyboard and they fixed it for free, and it was past the 1 year warranty and maybe even more than 2 years.
