• Legend
  • ✔ OK
  • Somewhat OK: requires additional tweaking or works worse than expected
  • Present but status unknown or untested
  • ✘ Does not work
  • nothing Not sure if present

• By default, sound is tiny (it does sound muffled). To correct this the pins need to be ajusted. Workaround: https://forums.FreeBSD.org/threads/how-to-solve-tiny-sound-on-a-macbook-pro-9-2-mid-2012.80741/

• The autosense of the headphone jack port while being correctly detected does not work when in the same association as the speakers and use the correct seq=15. Use a graphical mixer or sysctl hw.snd.default_unit=1 to switch to the headphones as a workaround.

1. The atp(4) driver is old making the trackpad fuzzy. Use the more recent kernel driver wsp(4).

1. Put the following on /etc/sysctl.conf:

hw.usb.wsp.enable_single_tap_clicks: 0
hw.usb.wsp.scr_hor_threshold: 20
hw.usb.wsp.pressure_tap_threshold: 120
hw.usb.wsp.pressure_untouch_threshold: 10
hw.usb.wsp.pressure_touch_threshold: 50
hw.usb.wsp.z_factor: 5
hw.usb.wsp.scale_factor: 12
hw.usb.wsp.debug: 1

1. To make the trackpad working in Xorg, add this to /etc/sysctl.conf:

kern.evdev.rcpt_mask=3
