The Mac OS Mavericks runs great on this laptop, but to get the wlan work, the original wifi card must be replaced.
The UEFI firmware prevent to start with other card than the original, which thing already made a lot of headaches to hp users.
I patched the firmware, and with an also patched flasher, I been able to overwrite the ROM with the modified version.
