Yosmite shows this message at startup
Recently I upgraded my Apple Mavericks to Apple Yosemite, then all is doing well. It’s just that there’s a time that this pop-up message occurs …
I google around and found this solution. The problem is that Apple is giving the wrong link which was the error thrown my Oracle. So by rite it should directs you to Oracles Java for OS X download page. The correct link to download is this.
Also please check this link from Apple Support Communities.
Have nice day! 😉
