Are security updates still available for download on my older iMac running High Sierra?
iMac 27″, macOS 10.13
Security features such as the read-only system volume, and the updates to the built-in anti-malware tools such as the addition of XProtect Remediator, will also require newer versions, among other enhancements made to macOS.
No. High Sierra is no longer supported.
Mostly you just need a more modern Browser than Safari on High Sierra, like Firefox or Brave.
