This doesn't mean someone can't sue you anyway, notwithstanding that disclaimer. Anyone can sue anyone in civil court. That's the way the system works.
Someone could track you down and sue you for the (bad) advice you gave that cooked their Macbook, even though they got that advice on SE and SE states that SE is not responsible for any damages resulting from the use of the information.
The TOS of all SE site(s) shows that anyone who uses SE sites is bound by this click-through agreement, even if they didn't read it.
And that should suffice in a court if it gets that far. It should suffice for any attorney thinking of taking the case of someone who wants to sue you. Again, someone could sue you; but chances are really great that it will never go very far due to the legal nature of SE and your contributions.
This SE site - Law SE - has more of a specialized TOS, as practicing law without a license is illegal, and giving legal information as a layperson (or even as an attorney, of which there are some who particpiate here) needs special terms; see the sidebar for this disclaimer and link:
Law Stack Exchange is for educational purposes only and is not a
substitute for individualized advice from a qualified legal
practitioner. Communications on Law Stack Exchange are not privileged
communications and do not create an attorney-client relationship. General Disclaimer - Law Stack Exchange
So, if you do get sued by someone who cooked their Macbook by following your bad advice, you can ask about the lawsuit here on Law SE. But, unless your question is about general legal procedures, terms, case law, etc. (as outlined at What topics can I ask about here? - Law SE), your question will be closed because this site is not for giving specific legal advice in specific legal situations, especially active lawsuits. You will be advised to talk to an attorney.
