My wifi dongle is not working on Big Sur. Whenever I tried to install the software that came with the wifi dongle, I get a message that the drive is incompatible. I was using a Wifi dongle from this company called Cuddy and when I contacted them, they said they are not sure when are they going to have a compatible driver for the same.

I found a similar post related to this over here when someone faced similar issue when Big sur was in beta phase.

And I was looking at Gummibando's answer where he mentioned the following:

While macOS 11 is in development, you can enable the loading of deprecated KEXTs by disabling SIP. See https://developer.apple.com/documentation/macos-release-notes/macos-big-sur-11-beta-release-notes (Deprecations).

However, the link is not working anymore. Any other solution to solve this issue?

While Apple hasn't realeased an official date for when third party kexts, they have been phasing them out for over a year now and over time the list of depreciated kexts is growing.

For now I believe that you can boot into recovery mode using Command and R, and then running csrutil disable in the terminal to disable SIP.

This is more like a temporary hotfix than a solution and I would advise getting a new dongle if your manufacturer does not keep up.

  • What does csrutil disable command do? I couldn't find any manufacture supporting MacOS 11 version and later releases.
