macOS catalina security update 2026-001 10.15.8 has just popped up on my screen. Is this some sort of phish or genuine ? I thought Apple stopped supporting my mac years ago ( late 2013 )

You can get this update from system Preferences/Software Updates where apart from the update to a higher System you should see a 'more updates' link.
This updates apparently only includes the security certificates neccesary to prevent apps such as Facetime stopping working in 2027.
Be warned: I did this and it took 30 minuts with three (automatic) restarts. It scrambled most of my 3rd-party email accounts; with assistance on the phone from Support I had to delete and then reinstall all the accounts (for which you need not only your password but the server details). This still threw up an error warning in each cazed: you have to click 'Trust' then set the first opotion to Always Trust': you need to do this twice (imcoming and outgoing) for it to settle down. This may not happen with your email accounts (no problem with iCloud) but it took me over an hour. (I was also signed out of YouTube though there was no problem signing back in.)
So don't start this unless you allow plenty of time.

Thanks for the warning, I started the update & went to make a coffee, when I returned to my desk about 10 minutes later it was done. Everything appears to be working correctly, no issues with my email 😃
I have an iMac (27-inch, Late 2023) running Catalina 10.15.7. It appears to have downloaded the security update. When I hit the Update Now button in the Software Update section of System Preferences, the computer restarts. But when I log in again, it still shows that the update has not been installed. I tried this many times with the same result. Anyone know how to resolve this?
Thanks for the link stedman1, better safe than sorry. I'm always wary of pop ups.
Is macOS Catalina security update 2026-001 genuine for a late 2013 Mac?
