If you're on Sequoia, I think it's due to be supported until around September 2027.

As far as I know, MacOS upgrades retain your user data by default, but Apple are known for breaking past standards in new versions of MacOS meaning that some software may no longer work.
 
If you think that's annoying, imagine Google Chrome which keeps asking me to update from macOS 10.13.6 to be able to install a new version of Chrome every single time I open their browser.

Both my 2010 Mac mini and my 2011 Macbook Air can't be upgraded past 10.13.6
Laptop here on Sierra running Chrome for a specific application (one website). Zero update notifications. :cool:
I always gut GoogleSoftwareUpdate on every computer I have to install something coming from that wretched place. There are instructions out there for how to do that on a Mac.
 
That would be an acceptable answer if there was a way to make that 1 in the red circle go away. As far as I can tell, there isn't. That's annoying. There's nothing reasonable about annoying behavior.
You can. Replace that icon in the doc with a link to the Prefs app. That’s what I’ve been doing for years.
 
From this day forward let it be know that ayephoner is a lover of slop.

Many posts from different members here about how buggy and sloppy version 26 is.
You will end up in a lunatic asylum if you go by the member complains here on everything. Just use your computers and enjoy life, it isn’t end of the world. Some of us endured Tiger and Lion OS X. Tahoe isn’t anything like those early mac osx releases.
 
I had Lion for years and years, I think it had that issue early on where USB drives would randomly disconnect. That was patched out and then it simply ... worked?! ;) The much-lauded Snow Leopard shipped with that very same problem...
