Good news for Mac owners that still use iPhoto 9 and are now upgrading their Mac to Yosimite. Only last week it would still have cost you money to upgrade your iPhoto 9 version up to the newer app store version. Which is the main reason why I never did it. After all, iPhoto 9 was working fine, so there was no need. But now that I upgraded to Yosimity, all of a sudden it did not start anymore. At first I was annoyed that Apple would force me to buy the new iPhoto through not making the OS X update compatible. But when checking, the new app was now free from the app store. Nice.
