exists for MacBook systems created before mid-2014Does this mean that my old iMac, which my daughter commandeered but isn't using, would NOT be vulnerable (even if it were powered up and in use?).
Are we still waiting for Apple to patch something before we reactivate Java? I'm using Firefox to avoid Safari with/out java, and I'm not preferring it . . .
Apple discontinued doing the updates for JAVA and instead lets Oracle handle the updates. You can turn JAVA back on if you have any need for it, but make sure you update it to the latest OS X version from Oracle. Most people don't really need Java and it merely opens them to several Trojans that they REALLY don't want.
JAVA Script is entirely different. . . but I find I really don't need that either.
The vulnerability is in the EFI firmware—which is exclusive to AMD64 computers—Intel-based Macs.
If the iMac is PowerPC-based, then you are safe (but a bit dated).
