Safari update
trying to update Safari and can't figure out how.
iMac 21.5″, OS X 10.10
Check for OS, Safari, and security updates in the App Store. If you can't get a new-enough version that way, switch browsers or upgrade the OS.
To upgrade, back up your data, check your applications for compatibility, and depending on which iMac model you have, click on El Capitan, High Sierra, Mojave, Catalina, or Big Sur.
