    I keep my MBP in my room which has the windows always up. For the past week however its been raining every day. I did not think about it too much until I looked at the forecast and it said it was 92% humidity that day. Apple states it should only be used at percentages from 0-90% humidity. Will my MBP get water damage because of this?

    It could. That is why Apple has all those moisture sensors throughout the unit. If they are tripped and the unit quits functioning they can declare it moisture damage and refuse a warranty repair.

    Normal humidity is (at least for north Europe) somewhere between 60 and 80 percent. The 92 percent you seen in forecast,is outdoor humidity,indoors it's probably more like 80 percent. Any humidity lower than 30 percent,combined with temperatures above 25 degrees centigrade,is dangerous for humans,due to dehydration.
    No,your computer is ok,it will turn off itself before damage can be done.

    Yeah, but I keep the windows open and my door is closed so the air should be the same as outside.

    I survived years of 110+ F weather in the SW US with 5-10% relative humidity. It was kind of nice to go running in the 110 degrees and not drench your clothes. Just a salt crust from the sweat.

    How can you know if the moisture sensors tripped?

    I wouldn't take a chance on it! These things are delicate and cost megabucks! Delicate and expensive is never a good combination.

    It's hard for an end user to know. If you look on Youtube there are videos showing some of the sensors. Ifixit sometime mentions them in their teardowns.

    And Apple keeps moving them around and adding more. Some look like little stickers that change color. Some are drop of glue like material. Also, from what I have read, some only show their changed color in UV light.

    As are starting point, this OLD page shows some of them from the 2010 MacBook Air. https://www.cultofmac.com/67303/new-macbook-air-has-record-amount-of-moisture-sensors/

    So the only way for me to know is if I tear open my MBP? In that case I will just continue to use it until I notice some problems. Possibly related, it was getting really hot for some reason so I worried something short circuited, but at the same time I was downloading Xcode so that could also be it.

    Yes, you have to open up the unit. The indicators are stickers, drops, etc that change color, usually to red or pink.

    I think you are correct that any heating was your workload. Installs can put a bit of a strain on systems. I would just keep on working away!

    Never had a problem and live in the sub topics, frequently working in the tropics; recently back from Thailand, Malaysia & Papua New Guinea. Inversely all so lived worked and lived in Xinjiang western China with humidity dropping of to 0% lot of static, still never had a problem.

    I don't see how relative humidity in the "normal" range is going to damage the MBPro.

    By "normal range" I mean the everyday humidity from "low" to "high" that we humans live in.

    If you take it out unprotected in the rain, well yes, that's certainly "enough humidity" to damage it.

    But inside, even on a humid day?
    Probably not.

    If you're concerned about the humidity in your room, why not buy a small dehumidifier?
    Cheap and easy solution (although you have to remember to empty out the pan!)

    Condensation is what they are concerned with. That is why the specs will read something like "Relative humidity: 5% to 95% noncondensing". This post explains the concern well. https://www.quora.com/Why-does-high-humidity-often-damage-electronics

    Bottom line, water and electronics do not mix.
