Before you install iOS 11 on your iPhone or iPad, please check to see if you rely on older apps which are not compatible with iOS 11. iOS 11 is Apple’s latest major release of software for iPhones and iPads, released at the end of September, 2017. For many years, I’ve recommended holding off on installing major upgrades since Apple often introduces major redesigns to the user interface and major upgrades often have anmnoying bugs. With the upgrade to iOS 11 there is another reason to hold off on upgrading. iOS 11 no longer supports 32-bit apps. This means that older applications that haven’t been updated in several years will no longer work. Here’s how you can check to see if you have any incompatible apps on your device.
Here’s how you can determine if any apps that you rely on are not compatible with iOS 11.
1. If your device is running iOS 10.3.1 or later then tap on Settings
2. Tap on General
3. Tap on About
4. Tap on Applications. You’ll then see a list of apps that are currently installed on your device that will not run under iOS 11. If you have some important ones on that list, see if there’s an update available, likely as a new app. If not, hold off on iOS 11 until you figure out a solution.
