About an hour ago, I got randomly booted off Chrome in the middle of doing something -- and then the Chrome icon down below completely disappeared, leaving an empty space that displayed the Chrome name when moused over but, when clicked, popped up the following message (which I didn't have the wherewithal to screencap): "You cannot open the app "Google Chrome" because PowerPC apps are no longer supported."
After a reset, I managed to get Chrome operational again and haven't encountered any problems yet, but the icon -- despite having full interaction restored -- is still gone despite all my efforts, and it's bugging the everloving fuck out of me.
I'm on OS X El Capitan, so I'm slightly behind, but I haven't found many clear sources about a problem specifically like this. Apparently the alert is official, but it might also be linked to a bug that I might just have been fortunate enough to avoid until now, but also maybe not because I only found that on one obscure site? Hoping y'all can help.
