I think I do not trust Apple anymore. I have MacBook Pro 2016 which I have gotten repaired thrice since I bought it around a year and a half back. In May 2018, when I submitted my MacBook in Orlando for repair, nobody could apparently trace it for a month and I had to contact VP of customer care through LinkedIn to get my mac back. I was assured with a written email that nothing apparently is wrong with my mac and I shouldn't worry. I joined a college in August and saved important data on my mac. It was working fine till September first week when it rebooted frequently suddenly.
When I contacted customer care through call they assured me nothing is wrong and no need to back it up, I was just told to follow steps of the tech advisor. As I followed his steps my mac suddenly crashed and stopped booting up completely. I requested them to get repaired as soon as possible and save my data. But I was told that they can't guarantee data recovery and next available appointment was a week later to the nearest store.
I think its wise to switch to windows, at least I won't get false promises for $2400.
