How do I check which version of an operating system is installed?
macOS Command Line Interface
There’s a simple built-in tool to discover the current version of macOS from the command line:
The result will look something like this:
ProductName: Mac OS X
If you would like to see the OS version, there’s a flag for that:
$ sw_vers -productVersion
- Select the Apple Logo (Menu) in the far left corner of the top panel on the desktop.
- Select About this Mac.
From a Debian Linux-based OS, like Ubuntu, two commands will tell you about your system:
uname -a and
Here’s what the latter command might output:
$ cat /etc/lsb-release
MacStadium Customer Dashboard
Another way to verify which operating system is currently running on your dedicated server is to log into your customer dashboard. Once you’ve selected a server you can view the installed operating system on the bottom left alongside it’S hardware configuration as well as it’s IP address.
