Hi everyone new to cachyos,I’ve installed it on my gaming laptop and is working fine.But I would love to run it on my 2017 imac 27" 4k,I have manage to download it with a wired connection and is working (also managed to install wireless too ).The problem I’m getting is after reboot,trying to connect the WiFi,entering my password just won’t work,I’m getting a box pop up with password incorrect,please enter correct one.I have search online and found a couple of articles on wifi driver issues,I have tried these but no joy.
Hopefully someone knows the problem and assit me,enjoying cachyos on the laptop.
Many Thanks.
Is this a T2 Mac?
If yes, see: T2 MacBook Installation | CachyOS
Thank you for your reply,No it is a iMac 2017 model 4k retina,I found your suggestion and tried it but it didn’t do anything thanks.
Sorry then. Try a LTS kernel maybe.
We only give support for the T2 Macbooks, currently.
That’s a shame guess I will have to use another disto for my iMac,thanks for your help.
Happened here recently (MacBook 9.2), on both disks and all partitions, after an upgrade. And not for the first time either.
That’s why I know about the stupidest firmware, Intel bugs and Mac sloppiness.
An update helped me to continue to be able to access the network of my choice. I hope you’re still here 
Sorry, testing is pretty limited. I dont have own hardware, nor I dont know what exactly is required to keep it up.
We are in contact with the T2 Maintainer, which takes a lot of work away.
Hi Everyone i wanted to give you a update on the wifi not working after install on my imac.After a lot of searching i guessed it to be my wifi card to be causing an issue.What i came up with was to buy a usb dongle,so today i plugged that in,connected it and reinstall cachy again,everything downloaded and it connected after install,i now have cachyos running on my Imac with a faster wifi connection now,fingers crossed it continues.

Hi, I am new to the forums and to CachyOS. Created an account to help troubleshoot this. I am running on a T2 Macbook Air, and have the same issue. Followed your T2 guide, ran all the commands, and Wifi appears to work after a reboot, but it is the password authentication that infinitely fails even with the correct password on multiple wireless access points I have tested. Let me know if there are any next steps to help troubleshoot. Thanks

I need to take more time to monitor the logs from dmesg, NetworkManager, lspci, etc. I just set up this device, and have other stuff I need to take care of for now. USB wifi dongle does work as a temporary fix, but I bumped this thread because it’s a pattern people are experiencing, so other people likely will run into it.
Did you got it fixed?
You maybe need to setup “kwallet” in case youre using KDE.
I have not gotten it working yet, and I do not believe kwallet is the culprit since it is working fine for everything else (even the wifi dongle). I mention authentication only as a means to target and isolate where the problem appears to be existing, but it might not actually be authentication. The OP mentioned none of their passwords worked, and that’s why it didn’t work overall. It’s the same for me even though I am using a T2 Mac.
I have a feeling this is going to be some deep dive work, and I just haven’t had the time to do it yet. I am equipped to help figure this out, but I just need some downtime. I will keep you posted, and will check in to see if you have posted any other troubleshooting steps.
Btw, I love the distro. This is actually farther than my T2 Mac has ever made it with Linux usability, so using a wifi dongle isn’t an issue. I do want to try to help you fix what the root cause of the problem is though. Thanks for getting back Peter.
The fix is to replace wpa_supplicant with iwd. I ended up using the t2 linux script on their website to see if it would work versus your series of commands, but I had the same issue. wpa_supplicant has issues with particular wifi router configurations…particularly ‘n’. @ptr1337
Here are the steps to follow:
- Use the CachyOS Wiki for T2 Macs to install the wifi and bluetooth firmware
- Edit the NetworkManager file located here: /etc/NetworkManager/NetworkManager.conf
My file looks exactly like below:
# Configuration file for NetworkManager.
# See “man 5 NetworkManager.conf” for details.
[device]
wifi.backend=iwd
- sudo systemctl stop wpa_supplicant.service
- sudo systemctl disable wpa_supplicant.service
- sudo systemctl enable --now iwd.service
- sudo systemctl restart NetworkManager.service
@ptr1337 , maybe you could automatically identify if the device is a Mac upon installing CachyOS, and having it use iwd instead of wpa_supplicant by default. iwd was already installed as a package as a part of CachyOS, so it’s already there.
