pdfslicer VS mbp-2016-linux

They don't have to be! PDF Arranger or PDF Slicer will do this for you much more easily than PDFsam would:

https://github.com/pdfarranger/pdfarranger

https://github.com/junrrein/pdfslicer

If you just want to add another page I recommend to use another tool like PDFSlicer or PDFArranger.

You could also look at how other people and organizations have implemented GitHub Pages in their projects. For example, PDF Slicer has a master branch which houses the code for their application, and a gh-pages branch which houses the code that produces the documentation website. You can also have a repository/branch that exists solely to create a GitHub Pages website like this Picross page.

Is this website out of date? Saying audio and wifi not working on several models still. Looks like it was updated a few years ago though.

Check this site for the status of Linux support on different Macbook models

I ran arch on a macbook (14,3 i think) for a few years and in addition to the wikis, this guide was useful: https://github.com/Dunedan/mbp-2016-linux especially the link to wifi issues which got mostly solved with some hex editing: https://bugzilla.kernel.org/show_bug.cgi?id=193121

That used to be a good solution in like 2015, but there are generations of Macbooks whose Linux support never includes working WiFi or audio: https://github.com/Dunedan/mbp-2016-linux

So far I'm underwhelmed, mostly because of the (understandable) limited support of Apple hardware, e.g., Touch Bar, Touch ID, etc. (As an aside, I've found this GitHub repo very helpful: https://github.com/Dunedan/mbp-2016-linux )

According to https://github.com/Dunedan/mbp-2016-linux the touch bar is "partially working". That link's got tons more information so check that out.

To boot from a USB stick, simply hold down Option after you turn the computer on and wait for the USB to show up in the boot picker. That said, all MacBooks after 2016 don't really have the best hardware compatibility with Linux due to missing drivers.

According to this, there's no supported firmware for the BCM4364 card. Does this mean I have no hope of using Arch without an ethernet cable? Is there any way to revert back to MacOS and take the firmware from there?
