Almost all Apple services to become unavailable for devices with older OS: Which devices are we talking about?

Almost all Apple services, with the exception of iCloud cloud storage, will become unavailable for devices running outdated operating systems, insider StellaFudge reported on Twitter.

"As of early May, access to Apple services, with the exception of iCloud, will stop working on devices running: iOS 11-11.2.6, macOS 10.13-10.13.3, watchOS 4-4.2.3, tvOS 11-11.2.6. You'll likely receive notification prompting you to update," the source wrote.

Thus, Apple services will cease to be available for devices running iPhone iOS 11 and lower operating systems, and macOS 10.13 High Sierra and lower operating systems for computers.

Apple's support website previously reported that the older versions of the software will no longer support Apple services such as the App Store, Siri, and Maps. There are also reports on the internet that iMessage and FaceTime will continue to work even on such devices.
