If you’re an Apple Watch Series 3 owner, you might want to keep it out of certain hospital environments.

A number of users have commented that their Apple Watch Series 3 have undergone unexpected reboots in the intensive care units of some hospitals. This suggests there may be specific ICU-related equipment used in hospitals that could be interfering with Apple Watch Series 3 with or without cellular functionality.

In the case of one user, an Apple Watch Series 3 unit he’d bought for his wife regularly experienced reboots every 60-90 minutes when wearing Apple Watch in the ICU setting. Even though the Apple Watch was replaced with a new unit, the issue persisted.

A number of anonymous sources within Apple have confirmed that routines exist within macOS High Sierra 10.13.2 that could grant applications access to protected kernel memory data. These measures, alongside existing programming requirements regarding kernel memory that Apple has implemented over the past decade, seem to have mitigated much of the issue.

The fix was further confirmed by developer Alex Ionescu, who called the code regarding the issue the “Double Map.”
