E7450 | Successfull update to macOS Catalina 10.15

Recommended Posts


What wifi device does it have, I believe the default is Intel. If that's the case, it's not supported in MacOS.

You'll need to replace it with a supported card, I recommend DW1560 as what the OP is using as well.

Update: 23 Dec 2019


I updated my EFI folder after having my bluetooth back to work again. As usual, I share it via Dropbox. In my case, as you might see, I have no kexts installed in /L/E

Install the latest clover release, then replace files and folder using my shared ones.

It's slightly different from Jake Lo's EFI published on official guide but for my experience this arrangement is working.


macOS release: 10.15.2


Feedbacks in case of use are highly appreciated.


Best wishes to all of you
