Apple has begun a trend of releasing a slew of operating systems at once. Given how much data is now shared between devices, that is probably a good thing, but it makes our testing a lot more difficult because instead of taking our time with one device and operating system, we have to ascertain the worthiness of four different operating systems. That’s right, once again we’ve suffered so you don’t have to. On to the results! 

macOS Sierra 10.12.6: Installed and tested successfully now on multiple Macs. Recommended for any users of Sierra. Will be automatically pushed out to Sentinel+ members. As a reminder, Macs running macOS Mavericks 10.9 are no longer secure and should be updated immediately.

iOS 10.3.3: An important security update for iPhone, iPad, and iPod Touch. We’ve had a few wifi/cell connectivity problems in the days following the update, but it’s unclear whether the problem is related to 10.3.3. Given the importance of this particular security update, we’re going to recommend 10.3.3 regardless. Note: iOS devices running iOS 9.3.5 or earlier should be upgraded to 10.3.3 immediately for security reasons. If the device in question cannot run 10.3.3 because it is too old, it’s time for a new iPhone, iPad, or iPod Touch.

WatchOS 3.2.3: Works great. No issues.

tvOS 10.2.2: Occasional freezes using Netflix, but otherwise OK (in our limited testing). This may be a Netflix issue. Given the nature of AppleTV it’s difficult to tell. Still recommend updating.
