apple : mac pro : full hardware supported?

[Mayuresh Kathe]

is the newer generation of apple hardware, especially the mac pro, well 
supported by freebsd?
my thinkpad had some twisted support for it's hardware, specifically 
lacked Wifi support and occasionally shutdown or rebooted on it's own 
and hence had to be sold back to the hardware vendor. since I am in the 
no-machine state right now, wondered if a monolithic ally well-built 
hardware like the mac pro be worth it.
thanks.
