Welp, guess I get to download a Linux ISO for my trusty 2012 macbook. Dang it!! Whole lotta my life is on that thing.
I would wait and see if it actually affects you or not. But it might not be a bad idea to download what you will need to do that and have it ready in case.
I highly suggest this, tried, used, and proven... :)

Back it up first. Then you can restore it to the Linux install. You shouldn’t lose anything,
