Dusted off my old 2005 G5 iMac...
... and would like to know how unsafe OS X 10.5.8 is with respect to internet safety. I've applied the most "current" update to Safari (5.0.6). I added the G5 to my home WiFi which has three Macs running 10.13.6 High Sierra and all applicable app updates.
I don't want to leave a gaping hole in my security by attaching the G5 to my Apple account and to my home network. I practice safe internet browsing and don't open "YOU'VE WON!! emails.
I'm just fooling around with the G5 and intend to retire it again in a couple days. It's actually a snappy performer for a 2GHz, 2GB iMac!
Thank you for any insight you can give me.
