I just installed Ubuntu 19.04 on a new 2019 iMac. I do not have the option of using Ethernet, so I need to have WiFi working. During installation I selected that I wanted to have the proprietary drivers installed, and I also made sure I had an internet connection by tethering my phone's internet connection through USB, however after installation when I go to the Additional Drivers section of Software and Updates, it says "No additional drivers available".
I have tried some of the solutions found on these forums, but none have succeeded so far.
In case it is helpful, I ran the Wireless Info script from My wireless/WiFi connection does not work. What information is needed to diagnose the issue?
The output is here: https://pastebin.com/bnp0M1F6
Any help is appreciated.
Thanks.
