Problems with firewire in HP Z400

Recommended Posts

Hi, I've installed OSX 10.11.6 El capitan in my HP Z400, and I have two problems: Audio and Firewire.

 

The most important problem for me it's the firewire connection, because in my work I used a firewire sound card.

My computer can't detect firewire device, by it gives energy to the device.

 

This is my system specifications:

 

HP Z400 hexacore x5650

12 GB RAM

BIOS version 3,57

OS X El Capitan 10.11.6 (15G31)

Nvidia Quadro NVS 300

Firewire built-in connection and PCI card.

SSD Samsung 850 Evo 500gb

 

And this is my clover files:

 

 

Could you help me please?

I really appreciate any help you can provide!

Aloha GuitarFa12,

 

Are you still trying to solve this. I believe that your FW problems are created by the HPET device.

 

I have your exact configuration and my Z400 works perfectly under 10.11.6.

 

Lmk if u still need help and I'll happily send u my DSDT and clover config.

 

That should do the trick for u :)

 

later ...

Unless you have the HP Z400, my DSDT is of no use to you.

 

Looks to me like you are running a couple of Gigabyte boards, a series 4 w/Core2Duo and 1st Gen i7.

 

I also have a series 4 Gigabyte board running 10.11.6. I have a reboot on wake problem with this one.

Mine is a G45 chipset while yours seems to be a P35. Did you ever experience reboots when waking from sleep ?
