10.9.2 update with dual GeForce GTX670 GPU and Thunderbolt issues

[quig451]

I got the kext from another source, version 5.1.66 from OSX 10.9.0.

I now have the Promise R6 working with 10.9.4, just going to let it bake with some stress tests and then will post the howto (pretty simple).

Promise R6 Working with 10.9.4 using PromiseSTEX.kext from 10.9.0 GM

WARNING, backup your stuff, you never know... not my issue if your life goes into a tailspin because your data disappears and you can't boot your hack!

--- Assuming you are running 10.9.4, steps (your mileage may vary of course) ---

1 - Obtain PromiseSTEX.kext from /Library/Extensions of 10.9.0 GM (v5.1.66)
2 - Move 10.9.4 version of PromiseSTEX.kext (v5.2.7) from /Library/Extensions to a folder elsewhere
3 - Move 10.9.0 version of PromiseSTEX.kext (v5.1.66) to /Library/Extensions
4 - Edit /System/Library/Extensions/AppleKextExcludeList.kext/Contents/Info.plist:

sudo nano -c /System/Library/Extensions/AppleKextExcludeList.kext/Contents/Info.plist

In nano with the plist open, find the key "com.promise.driver.stex" (hint: use ^W in nano to search)

Change the string node to "5.1.66" from "5.2.7"

Save and exit nano (hint: ^O ^X)

5 - Set mode on kext (sudo chmod -R 755 PromiseSTEX.kext)
6 - Set ownership on kext (sudo chown -R root:wheel PromiseSTEX.kext)
7 - Rebuild kernel kext cache (sudo kextcache -system-prelinked-kernel)
8 - Rebuild system kext cache (sudo kextcache -system-caches)

NOTE: Apple advises to simple touch the Extensions folder vs. using kextcache, so: touch /System/Library/Extensions and touch /Library/Extensions instead if you are so inclined.

9 - Shutdown, plug in R6, restart.
10 - Enjoy (hopefully, you see your R6 or R4 mounted)

I haven't tried hot-plugging, as my /Applications folder is on my R6 (and I don't need hotplug, so why bother!)

This looks very promising. Thanks.

Also works with version 6.1.64

But do

sudo chmod -R 755 PromiseSTEX.kext
sudo chown -R root:wheel PromiseSTEX.kext

and then


5 - Rebuild kernel kext cache (sudo kextcache -system-prelinked-kernel)
6 - Rebuild system kext cache (sudo kextcache -system-caches)

Sorry- very new to this and thank you in advance...

When I try step 1: where I am to Obtain PromiseSTEX.kext (v5.1.66) from /Library, I am only able to copy it. Is that normal? It's on my desktop copied-
Then, after I update to os 10.9.4, and try moving 10.9.0 version of PromiseSTEX.kext (v5.1.66) from my desktop to the extensions folder, will I be able to?
Will the older kext just overwrite the 10.9.4 version of PromiseSTEX.kext (v5.2.7) for step 3?

Another noob question when I get to this-

how do I- Find the key "com.promise.driver.stex" (hint: use ^w in nano to search)
What's nano?
I am trying to complete this tonight, so any help would be GREATLY appreciated.
Thanks for all the hard work!

Ok, after the last hour I have learned a lot about kext replacement and successfully installed nano to manipulate playlists..
Could someone elaborate on cordlesssnake's post when he mentions

But do
sudo chmod -R 755 PromiseSTEX.kext
sudo chown -R root:wheel PromiseSTEX.kext

this is one step I don't understand even though I have 5.1.66 kext, the playlist refers to 5.1.64

Just want to have my basses covered and if I have this answer I feel like I can move forward upgrading to os 10.9.4
Thanks!!

Doh, I did this of course but didn't write that step, will edit main post. Thanks for calling this out cordlesssnake.

You mention 6.1.64, do you mean 5.1.64?

The two commands above are to be done from the terminal window, and change the mode/ownership attributes of the PromiseSTEX.kext file. Its good practice to match the existing attributes of other kexts. You could also do a global permissions repair and it should take care of it (via Disk Utility).

The plist should reflect the version of the kext you have placed in /Library/Extensions.

Works great! Thank you~
Still no hot swap, and sometimes fails to mount after being shutdown, but I'm happy!
Thanks again, quig451.
