I already had the Lacie driver installed. Tried replacing the PXHCD file and repairing permissions, still unable to mount drive on USB 3.0 port. Same story if I use Kext Helper and inject.
Copy modbin's PXHCD_patched to desktop. Right click - get info - change name to PXHCD. Close info screen.
Install LaCie pkg. Open finder and navigate to System / Library / Extensions / PXHCD.kext
Right click on PXHCD.kext, select "Show Package Contents"
A new finder window will open with a contents folder - open MAC OS folder in the contents folder - here is LaCie's PXHCD file. Drag modbin's file from the desktop to this folder and drop it - enter password to let it happen. Close finder, repair permissions and rebuild caches. Reboot.
What's the problem?
Looks to me that it just works fine
max for usb 2 is 30mb/s as shown in the first xbench score
But on the usb 3 port you see it's going to 60mb/s
it is still a normal HD right, not a ssd?
Yes, but the speed shows up as "Up to 480 Mb/sec" for both the High-Speed USB 2.0 bus AND the Super-speed bus USB 3.0 ports - it should show much hugher for the 3.0 port. Also, the total xbench score for the USB 3.0 WD drive in the 3.0 port was .2 lower than in the 2.0 port - go figure. It should do a lot better than that!
