Excessive use if candles or smoking is likely to cover the inside of electronics with wax/tar. towers computer) will probably suck in more dust & dirt than ones placed on a table (iMac, laptop, …).

In regards to how frequently this might need to be done, this will depend on the environment where the computer is kept. I would then wait ~30 min for any moisture to disapate, after which I would reassemble and turn on the mac.įor laptops I would assume that it's enough to shut it down before opening it up and cleaning it. With my old 2008 Mac Pro tower (replaced in 2018) I used to occasionally unplug it and blow out the dust with canned air. I don’t know how worried I should actually be about the slowing down and lagging so any help is appreciated :)ĮDIT: The general consensus seems to be that I should either leave it at High Sierra since nothing is wrong performance wise it’s just the heating up - or to get Mojave/Catalina - I’m wondering about everything yallve said about taking the bottom panel off to clean the fans, is there a “best”/“safest” way to do this, and does anyone know if there’s a way to just back my phone up without updating ? That’s my biggest problem and I’d rather not cause a bigger problem by updating if i don’t have to :) Thank y’all, youve been really helpful !! I would just leave it at High Sierra honestly but I want to back my phone up to it and the people at Apple as well as most third party advice says the only way to get around the alert that says my computer can’t read my phone without snd update is to update. My sister tried to combat this same problem on her laptop by upgrading and now it’s really slow and laggy, which doesn’t work for me since I need a lot of responsiveness with my drawing tablet. However it’s getting now to a point where it’s not slow but it gets hot when I open any app.

I’m a digital artist and animator so I require a lot from it but it’s held up the last 6 years.

Should i update to sierra
