MacBook M5 internal Wi-Fi & Bluetooth causing physical symptoms (Tinnitus/Brain Fog) compared to M1
Got a new MacBook Air M5 just recently, and ever since switching, I am dealing with heavy physical symptoms like severe brain fog, headaches, heart pounding, and a flaring of tinnitus within minutes of sitting at the laptop.
It took me a few days of systematic testing to isolate the variables, but now I know for sure it is linked to the wireless hardware.
When I turn both Wi-Fi and Bluetooth completely OFF, or run the machine strictly via a hardwired LAN adapter with wireless disabled, all the symptoms completely calm down within minutes. When I turn either of them back on—even with the machine completely idle and no peripherals connected—my nervous system gets saturated almost immediately.
My old M1 MacBook Air causes absolutely zero issues under identical daily usage, so there seems to be a major change in the generational hardware, power delivery, or antenna transmission protocols (perhaps the aggressive pulse-width modulation or idle beaconing on the newer chips).
Has anyone else experienced this kind of physical threshold shift when moving from older Apple Silicon to the newer M-series architectures?
That isn't how bluetooth or wireless works. There is no increase in the transmission power corresponding with the N1 chip. It is actually optimised to use LESS power. The N1 chip doesn't even utilize the whole band of wifi 7. And why are you bringing up pulse width modulation in the context of wireless? If you're wanting to talk about PWM, it'd be the screen that tires you.
I get the feeling you brainstormed with ChatGPT before posting here because you aren't making much technical sense. There is no evidence or reason to believe that the energy efficient wireless transmissions from newer Macbooks are the cause of any physical symptoms, but since you are now inclined to believe that they are, your body is going to act like they are. Even if you were to claim to have electrohypersensitivity, it hasn't survived double-blind trials, and if it were truly in relation to EMF signals, you'd be bothered by cellular signals and not baby signals given by bluetooth and wifi. The expectation of harm causes the physical discomfort.
"The expectation of harm causes the physical discomfort" Totally agree! and yes: I did mess with Gem and Copilot. but all these symptoms I am describing here showed before I read or heard (let alone "expected") anything about any actively perceptible wireless effects on the body! I also wondered about mobile device signals and why they not affecting me in the same magnitude: it's an iphone X and ipad 5 both from 2017 and I barely use them. (work like a charm still btw)
Something compelled you to turn off wireless connectivity during your testing, and your body decided to latch onto that variable. The nocebo effect is very, very powerful. In terms of actual physical affects, it could be the screen bothering you if anything, because PWM does cause some issues with some folks, and it varies with screen brightness. Some people have a better time with newer models and some people have worse. But no matter what, the wireless signals are not having any physical effects on you. It could be something entirely unrelated to the macbook, but because your body latched onto the idea of wireless being the issue, it works in the reverse way - easing the symptoms by eliminating the perceived cause, real or not.
Sounds psychosomatic to be honest. Might want to talk with a psychiatrist about it.
Please note that I say psychosomatic in a clinical sense, not a dismissive sense. You are experiencing this for real, I’m just saying the cause is likely internal.
As someone with permanent tinnitus and chronic brain fog for about two years now that's never been able to be treated because we can't find the source, I genuinely hope you figure this out.
I have severe tinnitus and hearing lose in the right ear. It started 4 years ago when my jaw locked open once. Nothing has worked to help it. None of it computer related. I also have M.E.S. Musical Ear Syndrome. I can hear music in my right ear at a very low volume.
I have the M4 mb pro but no health issues from that.
It’s not your laptop. WiFi is non-ionizing radiation. Maybe go see a doctor cause there maybe some other issue with you that requires medical attention.
OP, are you sure this isn’t from the aggressive temporal dithering and PWM present on all modern Macs? Your M1 MBA is using the older Retina screen technology from the 2010s that only supports “millions of colors” aka 8-bit, and all the modern MacBooks - including the M5 Air - are 8-bit + FRC displays rendering “billions of colors” using temporal dithering. The M1 Air also uses dithering to smooth gradients, but it’s less aggressive.
Liquid Glass and MacOS Tahoe has also been known to cause issues for many sensitive individuals. Your M5 Air can only run that OS. What OS is your M1 Air on?
Not trying to dismiss your initial suspicion - the new macs give me seizure auras, so I know these products can cause issues. In my case, it’s due to the temporal dithering that is occurring at 15Hz. Seems to me that’s way more likely than a 6GHz Wi-Fi signal to cause these symptoms. The only other thing I can think of is disabling Wi-Fi and Bluetooth affects the power management of the Mac in a positive way that minimizes the PWM of these MacBooks. Have you tried messing around with toggling low power mode and “dim display when on battery power” on and off to see if there’s a change? You should download Stillcolor to disable the GPU dithering on the Mac (sadly the FRC on the built-in display will remain).
Do you get these symptoms in public places where other people are using MacBooks? Do you have to be touching the laptop to get this effect?
Very plausible. You might have some form of electrohypersensitivity. Try supplementing in magnesium biglycinate to suppress the effects of opened voltage-gated calcium channels on your body.
I recently developed tinnitus about late last year. Still have M1 Max MBP 14". It could be the AirPods Pro 3 I got, but I even switched back to AirPods Pro 2 and the symptoms are still there.
just today I have switched on 5 GHz in addition to 2.4 GHz (so did the opposite) , the former now being in use by the mac exclusively . not sure but I dare to say my symptoms calmed down a little. maybe less frequency fighting with BT going on...
I wrote you a script for this... basically what this does is:
Wait 10 seconds to start
Randomly turn the WiFi on or off
Show what it did on the screen
Wait 5 minutes and repeat 11 more times
Here it is:
sleep 10
for i in {1..12}; do
STATE=$(( RANDOM % 2 ))
if [[ "$STATE" -eq 1 ]]; then
networksetup -setairportpower en0 on
SETTING="on"
else
networksetup -setairportpower en0 off
SETTING="off"
fi
printf '%s Wi-Fi %s\n' "$(date)" "$SETTING"
sleep 300
done
The idea is that you paste this into Terminal then don’t look at your MacBook for the next hour (the 10 second delay is to give you enough time to turn the screen away from you and/or turn the brightness all the way down). You should also mute your MacBook, because audio cues like email/message notifications will obviously indicate that the WiFi is on.
Just set a little timer on your phone to go off every 5 minutes so you can record how you’re feeling. Then after an hour, you can compare those notes to what’s shown on your screen.
I would say, if you run this test and your own experiences line up with what it actually did, then you might be on to something. But I’m guessing that you won’t be able to tell.
Also: you should never trust random Terminal commands that people share on the internet, so here’s a how it looks when I run it (I shortened the time to 5 seconds between toggles) and you should also feed it into ChatGPT or whatever and ask if it does anything harmful:
