Just received a note from Apple that my "Legacy Extensions". will not work with future Mac OS. What are Legacy Extensions? I have never heard of them. and are unaware of what program they might be trying to run.
Yes, you have them as do we all. They are additions to the operating system that provide functions not present in the operating system as installed. Software developers use them in order to add certain features to their software that they could not otherwise provide without their additions.
When you install third-party software these extensions, if required, are installed along with the software. Starting with the yet to be released new version of macOS, Big Sur, Apple will prevent such extensions from working. Software that you now use that depends on an extensions will have to be upgraded by the developer or it will no longer work. Apple believes this will help increase system security and reliability while reducing crashes.
I hope this answers your questions, satisfactorily. If not, feel free to ask.

They consist of code that "extends" or adds to or modifies the routines stored in the kernel. The kernel contains the lowest level routines needed to control and manage system functions and resources. It acts as an interface between the hardware and software.
There really isn't much you need to know for the future. The third-party software you use will have to be upgraded or it simply will not work. It will be up to the software developers to take care of the problem, if they wish to keep you as a user.
You will be better served by continuing your process of learning about the computer instead of fretting over "legacy extensions."
About legacy system extensions - Apple Support. You need not worry about these at the present. I suspect a tool will become available when it comes to tracking them down and deleting or replacing them. Software upgrades will likely do the trick when the time comes.
You should always wait a few iterations of a new OS to get the bugs worked out, that's likely a year from now!
No need to worry, but to see them, just don't upgrade to 10.16 if the developers don't have updates...
About this Mac>System Report>Software>Extensions, click on Obtained from Header, all that aren't Apple are Legacy.
Well, I understand what extensions are and what they do, Thank You, but what I am curious of is what they are extensions of? What program or software? It would be nice to know that for future updates.
Again, I apologize for being computer (MacOS) stupid in all of this. I'm still trying to figure out where everything is and how to access it after my files were all transferred (?) from a Windows 7 laptop to my new Apple Mac Catalina desktop.
I'm new to MAC and not a computer guru. I still don't know what they are, who they're from, and do I have them or not!
Thank You!
You're absolutely correct. Thank you for your feedback!
What are Legacy Extensions? I don't recognize that.
