I get what you're saying also, but some things to keep in mind. When you said 55,000 people clicked the Me Too button you have to take much of that with a grain of salt. Many people are not genuine or honest. Here's a good example of what happened to me today. I went on Reddit and someone said they were looking for a low budget computer that's only going to be used for basic MS Office and emails. I suggested to get an iPad. You can get them used for cheap. I got downvoted with rude replies from people that absolutely hate Apple. They hurled hateful comments at me for even suggesting Apple. That kind of behavior really makes social media look very bad. Obviously these are Windows fanatics who simply hate Apple. I was genuinely trying to address the OP's question.
I'm mentioning this because the 55,000 people that clicked Me Too are not necessarily people that have this issue with their MacBooks. It takes only one complaint thread to generate 100 replies siding with the OP against Apple. And those extra 100 replies are generally not Apple users. They look for any threads negative towards Apple. Please know this is a very real thing.
" I would also like to mention that most people who have this issue will not post on a forum about it,"
Yes, and there are also thousands more that don't post because they are not having issues. It goes both ways.
I'm not sure why Apple would take 1-3 weeks to repair your computer. I've been a Mac user exclusively for the past 20 years and even with today's outrageously busy Apple stores the genius has always quoted me 5-7 business days and they've come through. In fact I've never known Apple to take up to 3 weeks for a repair. That's unusual.
I absolutely respect your post and your concerns. Here's the issue I tend to have with forums. (which is the reason I left Macrumrors. The Apple troll central) People try their hardest to lay it on thick. If it was truly only the people like you who really have an issue then I would fully support it. There are lot of Apple haters who start up new accounts just to regurgitate someone else's issue about their Mac. One new member came here last week stating, "I recommended my friend a MacBook Air, but with Apple screwing up these horrible keyboards I will suggest them to return it so I won't get blamed". That was very frustrating to me because this member was trying to create a negative spin. How can anyone take that type of post seriously? There was nothing wrong with that member's friend's MacBook Air (if that story was even true). He just wanted to make Apple look bad for no reason.
There's also one more thing I would ask you to keep in mind. Apple is not a stupid company. Neither is Dell, HP, Lenovo or Microsoft. No company will purposely continue to sell their products that they know for a fact are constantly defective. It would cost the company a ridiculous amount of money repairing computers within the warranty.
While I definitely sympathize your situation of needing your computer, please understand you're not alone. I use my Macs to run my business. You're a student. Think how it feels when business owners like me can't run their business when their computers are in service. That's the life of tech. That's something we have to deal with.
I definitely hope you get your issue sorted out but social media has become a place for people to display hateful comments while hiding behind a computer. You never know how genuine people are. Thanks for listening.
