LLMs. I’d be surprised if there’s a tech support problem they can’t solve. If so, it’s probably so interesting you can write a blog post about it and/or post it to HN.
I have yet to encounter the tech problem they can solve. LLMs really suck at troubleshooting, they love to go on esoteric tangents that are unlikely to succeed and then get hung up there.
LLMs are great at hallucinating menu options that dont exist and entire features that dont exist just to get to the end. Have fun with that.
For questions about Apple products, I've often had multiple models answer by websearching discussions.apple.com.
