A tech canary is a small, round, green dot that pops up when you press the “Tools” icon on your Mac.
It’s an icon that tells you the latest software version.
The icon also tells you that the current version of the software you’re using is up to date.
If it says “Up to date” or “Upgraded”, that means that your Mac is running a newer version of software than the one you were using before.
It also means that the Mac is not up to version 10.5.6, which is what you’re likely running.
It does not indicate whether the current software version is 10.4 or 10.3.
It is, however, the best way to determine whether the software version you’re currently using is 10 or 10 (or even 10.2), and that it is also compatible with earlier versions of macOS.
If you have multiple versions of software on your computer, you can use the canary icon to check whether all of them are up to your current version.
When you run the “Info” utility, you will see a list of all the current versions of your current software, along with the versions they’re compatible with.
The “Info/Version” utility will display the list of supported versions, along the list with the latest version number.
For example, if the version is 8.2.3, you should see the version number 8.1.4, followed by the version 8.3 and the version 10 of the version you are currently using.
If a newer software version was released, the version of that software you are using should be listed next to the version on the icon.
When it’s the latest versions, you may be able to see the difference between the version with an asterisk (*) and the newer version with a dot (*).
If the version does not match, you are not currently running a compatible version of macOS, and you should be aware that the version it’s running is no longer supported.
If there is no version number in the icon, you’re not running a supported version.
If the icon says “Support”, then you should install the software, but if the icon does not say “Supported”, then your current OS version does NOT support this version of your Mac, and the software should not be installed.
If an icon says a specific version of Mac OS X is supported, it means that Mac OS is being supported by that specific version.
In addition to the canaries, you also may see a “Not running” message if you’re seeing an icon with an exclamation mark next to a software version number, such as “10.3.”
If you click the icon and see the icon with a red X next to it, that means the software is not currently being used, and it’s not installed.
The version numbers displayed in the Info and Info/Version utility icons are the only indication of the current compatibility status of a Mac.
When running the Info utility, it is possible to see an icon showing a list in the upper-left corner of the Info window.
If this icon appears when you run Info, then your Mac has been updated to the latest Mac version.
Mac OS 10.7 (Lion) or Mac OS 11.5 (Snow Leopard) or 10 and later (Wily Werewolf) or OS 10 and higher (Mountain Lion)The icon on the left of the icon on a Mac indicates the current Mac version number: 10.6.5, 10.8.1, or 10, or an earlier version of 10.9.5 and newer, or newer 10.10.1 or 10 or older 10.12.1 The icon on top of the Mac icon indicates the version installed: 10, 10, 11, or 12.
The name of the application is shown in the lower-right corner.
The Mac version of an application that you have installed is listed in parentheses next to that version number and the application’s name.
The list of versions listed in the right-hand column of the information icon includes all of the supported versions of that application.
The current version, if any, of that Mac version is displayed in bold.
If any of the versions listed have an asterisks (*), the version listed has not been updated since the Mac OS version was last updated.
If your Mac OS software version does have an update number, the Mac version in bold is the latest update, and if the Mac has an older version of this software version, the older version is listed.
If no updates are listed, then the software has not recently been updated.
OS X Yosemite or later (High Sierra) The icon shows a list next to your installed Mac OS versions in the top-left of the window.
The number of available applications is shown next to each installed version of OS X in the list next.
This icon indicates that OS X version 10 or later is currently installed.
