Your Java version if out of date. (but it isn't- Java 8 Update 111)
*iMac late 2013, macOS Sierra v. 10.12.5
A website that I need to access uses Java. I've accessed this website many times without incident.
Today I signed in- and the Pop up for Java appears, giving me options to update :later, block or update:
I checked System Prefs>Java>Update - Your system has the recommended version of Java.
...
I was able to use the website by clicking "later"- just wondering if perhaps this pop - up wanted me to update or install something that really is not legit.
Thanks
