The ‘Operating system’ dimension shows the operating system and version that the visitor used. If you have features on your web-property that are OS-specific, this dimension helps you understand which operating systems are most common.
This dimension references a lookup table internal to Adobe. The lookup value is based on the User-Agent
HTTP header in image requests. If you use an AppMeasurement library (such as through tags in Adobe Experience Platform), this dimension works out of the box.
Dimension items include operating systems that visitors use. Examples include "Windows 10"
, "OS X 10.15"
, and "Android 9"
.
Below is a list of specific issues with how operating system has been represented in the User Agent and in Adobe Analytics reporting.
Starting with Version 11 we will use MacOS instead of OS X to refer to the Apple operating system.
Examples:
The User Agent on Apple computers shows the OS version as 10.15.7 even if it is a newer versions. This was done because including version 11 in the UA apparently caused problems with some websites. This is true for all browsers and is not related Google’s ‘freezing’ of the User Agent on Chromium browsers.
Note that client hints include the correct version in the platform version hint (“Sec-CH-UA-Platform-Version”). This is a high-entropy hint so is not automatically collected by Adobe. See the Adobe Analytics Hints FAQ for details on how to collect high-entropy hints.
As of January 2023, The User Agent in all browsers shows represents Windows 11 as Windows 10.
Note that client hints include the correct version in the platform version hint (“Sec-CH-UA-Platform-Version”). This is a high-entropy hint so is not automatically collected by Adobe. See the Adobe Analytics Hints FAQ for details on how to collect high-entropy hints.
