Need both. Should work OOTB for your z270n.

Is the wifi build into the board or does it come with a little card? I’m planning to use my board with a hackintosh build and I need to use a special adapter (https://www.amazon.ca/gp/product/B01KHRJVXW/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1) and wifi card (https://www.amazon.ca/gp/product/B01LH9JKYY/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1) to make wifi work. Do you know if I’ll be able to switch out the board’s wifi solution with mine?

Unscrew the two screws from the underside of the motherboard that are used to secure the metal housing. After it's unscrewed, the whole thing should lift straight out (The stock Intel wifi card should pull out of its socket without a lot of force).

There's one more metal screw on the side of the metal housing securing the top flap in place. Unscrew that, then carefully wiggle the top flap off of the housing. This is the result: https://i.imgur.com/qxuEr1E.jpg

Next, you'll need to buy a Macbook Broadcom wifi card and an NGFF(M.2) adapter.

• WiFi Bluetooth Air Port Card MacBook Air 11" A1465 13" A1466 2013 2014 2015
  
  Unscrew the large screw attaching the old Intel wifi card to the housing. Carefully pop off the two wires attaching the antenna to the card. Then remove the Intel card and put the M.2. adapter in its place. You may have to do some gentle wiggling/prying, as the stock card is secured with some adhesive.
  
  When installing the adapter, make sure of three things. 1) Align the adapter so that it's sitting at about the same height as the old card, so that the pins will correctly re-insert into the mother board. 2) Use the included plastic screw (not the original metal screw). I don't know why, but the metal screw may render the whole thing non-functional. My plastic screw was a little bit longer than the original screw, so I also used 2-3 of the original metal washers underneath the plastic screw. 3) Be careful not to overtighten and break the head off the plastic screw.
  
  Here's a picture of the adapter installed: https://i.imgur.com/1oRGP84.jpg
  
  Finally, insert the Macbook wifi card (Broadcom) into the adapter and secure it in place. Reattach the two antenna wires to the Broadcom card. It shouldn't matter which wire you attach to which terminal. I don't have a photo of this because my Broadcom card has not arrived in the mail yet.
  
  The original metal housing flap won't fit back on the housing now, as the adapter and Broadcom card are too tall. Plug the whole thing back into the motherboard, and reattach from the bottom side with the original screws.
  

Sorry for the delay!

For the wifi card, I used a MacBook Air BCM94360CS2. To fit it into the m.2 slot, you'll need an adapter. I purchased the BCM94360CS2/BCM943224PCIEBT2 Card To NGFF(M.2) Key A/E Adapter For Mac OS from Amazon. As for a tutorial on how to swap out the wifi card on the mobo with the apple one, I followed the tutorial shown here. Happy hackintoshing!

Working great in my ITX hackintosh. You may need a little longer WiFi cables because the card will be a little taller than the stock one. Works nativley in MacOS but you need install the bootcamp drivers in Windows. Here is the guide:

https://www.tonymacx86.com/threads/100-working-12-6-pin-apple-wifi-bt-card-to-m-2-ngff-adapter-handoff-unlock-with-watch-uefi.215895/

Edit: the card shipped quickly, but the adapter took about 2 weeks so try to find a local seller.

1. Unless you 've replaced the combo Wifi/BT card in your EliteDesk, that card won't work. Apple has never used Intel-based Wifi/BT cards and they are not supported. This is why your wifi doesn't work. Go buy a supported wifi card found here and get this adapter card. to find the M.2 card in your wifi slot. For full Continuity/Handoff support, you really need a supported Broadcom card. You can find a list of supported cards here.
   
2. Be forewarned, you are likely get some hate due to mentioning Multibeast in public. All tools can certainly have their use cases, but the conventional wisdom is vanilla installs are much better than using the Unibeast/Multibeast methods due to the fact that Unibeast/Multibeast place updated files within the MacOS filesystem, whereas Vanilla install methods keep all of the driver changes contained within the UEFI partition. The implication is Apple updates can easily break your machine if you are changing files inside of MacOS, but it is generally far safer to keep your changes in the UEFI partition because Apple leaves that partition alone.
   
3. Your EliteDesk 800G3 is very similar to my EliteBook 840 G3 laptop, as both are based on the same architecture, same generation and similar motherboard. You can likely get pretty far following Rehabman's guide for the Probook/Elitebook Mojave install. See this thread and this guide.

I have one of [these] (https://www.amazon.com/Hobbypower-BCM94360CS2-BCM943224PCIEBT2-Card-Adapter/dp/B01KHRJVXW) and another of the same model from a different manufacturer.

Hey, following up here. I've replaced the wifi m.2 with this broadcom chip and hobby power adapter and I'm failing to get it working in windows 10.

If I can't get it to work, I want to try your method. Can you confirm that this is the card you are using?

Okay for sure man. I do have a hardware question though.

Is there different shaped adapters for the wifi cards? Sorry that might not make sense.

I saw a thread that a few people are using a BCM94360CS instead of a BCM94360CS2.

The former has 3 antenas and the screw hole isnt center like on the BCM94360CS2.

Does that screw need to be used? Can that card be used with this adapter, even though it looks like the screw hole wont line up, as it is offset.

Sorry if thats confusing.

And sorry again, I didnt see the wireless buyers guide before and did do a search, I think I was all over the place when I posted.
