Creating videos without infringing on trademark or copyright laws

[KaratheComputerTutor]

Hi, I'd like to create a channel with original videos about how to use Apple products. I see tons of such videos already on YouTube. I'm wondering if I can post such videos legally. I just tried to contact Apple's legal department but don't know if they'll get back to me. In fact, Apple's website explicitly states the legal department may not reply. Any advice is appreciated. Thanks.

Like a tech reviews/guides channel that should be fine I don't think any brand would really care maybe unless you were slandering or saying defamatory words about them.
