Ubuntu 20.04 with Wifi on iMac 2019 (MacOS 11 - Big Sur)

The purpose of this document is to summarize some of the things I had to figure out to successfully install Ubuntu on my iMac '19 27" 5K, a.k.a. iMac 19,1.

t2linux

From what I could find, iMac's do not have the t2 security chip. However, it does share hardware (and firmware) with contemporary Macbook Pros. For this reason, the t2linux.org website contains lots of helpful information about how to install Ubuntu on an iMac.

However, the guides on the t2linux website did not work for me when I ran it, so I had to mix and match some old pages from the wiki to make things work. Also, most issues are focused on Macbooks, not iMacs.

First of all, please note that token expiration and revoking are two different things.

1. Expiration only happens for web apps, not for native mobile apps, because native apps never expire.
2. Revoking only happens when (1) uses click the logout button on the website or native Apps;(2) users reset their passwords; (3) users revoke their tokens explicitly in the administration panel.

1. How to hadle JWT expiration

A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.

Quoted from JWT RFC:
