A new information popped up on my Mac this morning: "Your computer contains legacy system which will not be supported in the future updates." (or something to that meaning). Sadly, that note is note accompanied by any information as to which app/software (among the many on my Mac) it is. How do I find the problematic piece of software to a) get rid of it or b) replace it with a newer version?
MacBook
For now, you can safely ignore the notification. It won't be an issue until Big Sur is released and even then, the extension will not run without an update from the vendor.
Thank you, then at least till Big Sur I will just ignore this :-)
You're welcome. Good plan. :)
