AppleTVs automatically update. They do so using a process similar to how iOS updates, but instead of looking at the feed I posted in https://krypted.com//mac-security/how-the-os-x-caching-server-caches-updates/, they look at http://mesu.apple.com/assets/tv/com_apple_MobileAsset_SoftwareUpdate/com_apple_MobileAsset_SoftwareUpdate.xml. The AppleTV feed is similar to that available for iOS updates, with each dictionary having roughly the same data: <key>ActualMinimumSystemPartition</key> <integer>1482</integer> <key>Build</key> <string>13Y6234</string> <key>InstallationSize</key> <string>0</string> <key>MinimumSystemPartition</key> <integer>1534</integer> <key>OSVersion</key> <string>9.2</string> <key>ReleaseType</key> <string>Beta</string> <key>SUDocumentationID</key> <string>PreRelease</string> <key>SUInstallTonightEnabled</key> <true/> <key>SUMultiPassEnabled</key> <true/> <key>SUProductSystemName</key> <string>iOS</string> <key>SUPublisher</key> <string>Apple Inc.</string> <key>SupportedDeviceModels</key> <array> <string>J42dAP</string> </array> <key>SupportedDevices</key> <array> <string>AppleTV5,3</string> </array> <key>SystemPartitionPadding</key> <dict> <key>1024</key> <integer>1280</integer> <key>128</key> <integer>1280</integer> <key>16</key> <integer>160</integer> <key>256</key> <integer>1280</integer> <key>32</key> <integer>320</integer> <key>512</key> <integer>1280</integer> <key>64</key> <integer>640</integer> <key>768</key> <integer>1280</integer> <key>8</key> <integer>80</integer> </dict> <key>_CompressionAlgorithm</key> <string>zip</string> <key>_DownloadSize</key> <integer>856434408</integer> <key>_EventRecordingServiceURL</key> <string>https://xp.apple.com/report</string> <key>_IsZipStreamable</key> <true/> <key>_Measurement</key> <data>cm8k41In38EOJEj20IwJp5Suskw=</data>…
