I understood that you meant to download the driver for the internal wifi via an ethernet dongle.
The big problem ist the T2-Chip, which blocks access to the internal drive if it is not MacOS (or Bootcamp Windows). This is the problem which I was aiming on with my initial question.
The frustrating part of your help was, that you simply did not know anything to help with the T2 Chip, but thought simply pointing to the apple page which is fairly simply found via google.
To be fair, it seems you don’t have experience with the T2.
The answer “Install the driver from the internet” is helping like dell asking “Have you plugged in your monitor”. Which is also not helpful.
As you stated, this is a Linux and nobody is holding your hand, but a forum is exactly the place where you ask people when a simple search on google/github/gitlab/askubuntu/etc. does not help. Especially with driver, since as you surly know, you can not download driver from the manufacturer.
On Github and other resources you find plenty of information on how to install and where to get driver for MacBooks 2016 and older.
Many resources for Keyboard/Mouse/Webcam etc. But for 2018 it is sparse, and has no use if you can not use the internal storage.
And it is fun to solve puzzle, but only if there is a solution. With the current state, as long as I don’t become an embedded developer and create the driver myself, there seems no solution for the T2 problem.
Thats why I asked if Budgie has a fix for it, since they claim that you only need a modern mac book.
The suggestion of an older MacBook is a fair solution.
rEFInd is a pain in the ass, but you can “abuse” the Mac Bootloader to dual boot (at least with my old solution, but I’m sure that it should work with internally installed linux)
The SD-Card “shortage” looks cool! But on the MBP 2018 they removed the SD-Card slot. But luckily there are small usb-c drives. But after installing docker, IntelliJ, etc, usually an small usb-stick is full. (reminder T2 blocks access to internal drive to use as storage)
And no, I didn’t see the gnome touch gestures, and the look super awesome!
