Today I finally updated iTunes on my Macbook and found iTunes radio was missing or removed. I searched around and it looked like iTunes radio had been removed by Apple. In fact, Apple have just hidden the settings to turn internet streaming radio on.
Open the new iTunes. In the top menu near the Apple logo tap the iTunes word and select Preferences. Then tick the box for internet radio and hit ok. Now when you go to music in iTunes you’ll see an option for internet. This is internet streaming radio on your Mac again.
