It’s easy upgrade all your iOS apps directly on your iPhone – you just go into the ‘App Store’ app on your iPhone and press the ‘update All’ icon. But it can be a bit tricky trying to find out how to upgrade all the apps from iTunes on your mac. Here’s how to do it.
1. Firstly you need to go to those 3 dots on the left of your iTunes window and find the ‘Apps’ dropdown menu’
2. Now you can click on the ‘Update All’ button on the bottom right of the screen.
The trick is, you don’t do it through the ‘iPhone’ menu in iTunes. You can see all the apps there but you cannot update them. You need to do it through the ‘Apps’ menu in iTunes.
