I updated to OC 0.6.9, but it seems that my audio output isn't working anymore. Any idea what's wrong? See attached my efi without serial info. Also following Dortania doesn't really make it clear for me whats wrong with it.

Thanks


Edit: Nevermind, I needed to plug the cable in the DisplayPort output nearest to the VGA port.

I want to try to get WiFi and Bluetooth working on my Optiplex 9020 USFF, using the OpenIntelWireless kext.

I've just ordered the following WiFi/Bluetooth card:

This Ebay seller mentioned that you should choose the one (with the A10-13 connector) that is compatible for Dell PC's. Hence the previously ordered card.

Compatibility as per:

Once it's in I will see if it works! I'll keep you updated. :)

Here's the CaseySJ mini guide for configuring OpenIntelWireless drivers.
Here is the Amazon.com link to the card for those in the USA and Canada.

Readers should note that Handoff / Continuity features of macOS are not yet enabled by Intel Wifi/BT cards so if you must have those two features, opt for a supported Broadcom card instead of Intel.

Look forward to seeing your results with this new approach to affordable hackintosh Wifi. :thumbup:

If anyone wants to attempt Intel Wifi BT via a PCIe adapter in their MT or SFF here is one option.
The Archer T5E adapter from TP-Link.

https://www.amazon.com/dp/B084JPFKQ5/?tag=tonymacx86com-20
https://www.newegg.com/tp-link-archer-t5e-usb-2-0/p/0E6-002W-005N2

This adapter is using the Intel 7265NGW card which is supposedly supported by the new Intel drivers.
I have not tested one of these yet. It looks promising as it offers high speeds and BT 4.2 vs. BT 4.0 on Broadcom cards. You can set your router to broadcast 5GHz only to avoid BT interference at 2.4 GHz frequencies.
  • Intel(R) Dual Band Wireless AC 7265
  • Intel(R) Dual Band Wireless N 7265
  • Intel(R) Wireless N 7265
Remember that the BT cable must be connected either to a USB 2.0 header or USB 2.0 port for BT to function. If you do buy one and test on your 7020/9020 SFF/MT please post your results here. The Intel drivers will only get better as time goes on so this is a viable alternative to more expensive Broadcom based cards that may also have support dropped by Apple in the future versions (12,13,14) of macOS.

Some benefits of going with TP-Link and Amazon or Newegg.
  1. Faster shipping than ordering from China
  2. Easier returns if you do need one
  3. TP-Link's product warranty that is much longer
  4. No need to assemble from individual parts

Warranty coverage falls into the 2-3 year Home category.

Maybe this has already been addressed, but I'm a bit confused about updating the config.plist I generated using OC-Gen-X. In the video the example config.plist is quite a bit different, in that I have extra entries in mine that don't exist in the example. In the video, there's an entry in the example under NVRAM for csr-active-config that has a different value than what I generated as well as the one in the video. However, in the video he doesn't change it. That is just one example of several similar instances. Just confused on exactly what is supposed to be changed, because it appears we're not supposed to use everything if it is different?

In short, just confirming that we're only actually making the changes that were made in the video?

Thanks again for your guides.

When you use the latest OC Gen-X app you'll get the latest OC version. It should be 0.6.9 right now. The video was done long ago with OC 0.6.3. There will be some differences after OC gets updated and things change. Pavo makes adjustments to the .plist as things in OC change. You can read the OC documentation on the dortania github site.

Yeah, I get a notification actually that it expects OC .7.0, but that I'm running OC .6.4-.6.9. Not sure what that is about. I looked everywhere for OC .7.0. Maybe it's expected to drop soon.

Thank you for the info.

One last question. I haven't updated to Big Sur yet. If I boot successfully to Catalina using the new USB drive, can I just mount the EFI once I'm logged in and replace the Clover EFI that's already there?

Just looking to at least try upgrading before I do a clean install.
