Suspend Workaround¶
S3 suspend has been broken since macOS Sonoma, it has never been fixed,
but this workaround will make deep suspend work. Currently this
workaround works only on Arch based distros.
Create and edit this file: /etc/systemd/system/suspend-
fix-t2.service
Check your modprobe and rmmod location by running:
which modprobe
which rmmod
Taking the example as /usr/bin for location of modprobe and rmmod, copy
the following to /etc/systemd/system/suspend-fix-t2.service. If the
location is different, do the changes accordingly.
[Unit]
Description=Disable and Re-Enable Apple BCE Module (and Wi-Fi)
Before=sleep.target
StopWhenUnneeded=yes
[Service]
User=root
Type=oneshot
RemainAfterExit=yes
#ExecStart=/usr/bin/modprobe -r brcmfmac_wcc
#ExecStart=/usr/bin/modprobe -r brcmfmac
ExecStart=/usr/bin/rmmod -f apple-bce
ExecStop=/usr/bin/modprobe apple-bce
#ExecStop=/usr/bin/modprobe brcmfmac
#ExecStop=/usr/bin/modprobe brcmfmac_wcc
[Install]
WantedBy=sleep.target
Enable the service by running: sudo systemctl enable suspend-
fix-t2.service
If you are facing issues with Wi-Fi on resume, uncomment the lines
having brcmfmac and brcmfmac_wcc in the above file.
Note
Make sure you have CONFIG_MODULE_FORCE_UNLOAD=y in the kernel config. To
check, run: zcat /proc/config.gz | grep "CONFIG_MODULE_FORCE_UNLOAD" on
Arch based distros.
