Mac information: all the technical characteristics

Mac information all the technical characteristics

No need to open a Mac to know its technical characteristics! macOS can tell you its exact model, components, storage capacity, system version, and even installed apps.

A Mac is simple. So much so that we sometimes forget that it’s basically a computer like any other, with hardware and software. And if you can use it daily without ever asking the slightest technical question, as you do with some cars, it is sometimes useful, even necessary, to have some precise information on its configuration. For example to ensure that it can be updated to a new version of macOS as Apple offers each fall, to take stock of its storage capacities, or to intervene in the event of a problem or incompatibility. .

No need to open the box or use expert software to get all these technical details! With macOS, you can know everything about a Mac without putting your hands under the hood, simply by going through the Apple menu…

Two clicks are enough to get the essential information on a Mac, whatever its model.

  • Click on the apple menui.e. the Apple logo, always accessible at the top left of the screen in the menu bar of your Mac.
  • Then click on the first option, About This Mac.
  • The window that then appears in the center of the screen displays essential information about the Mac.
  • The name and version number of macOS installed on the Mac.
  • The type of Mac and its model year. This information is important because it allows you to make sure that your Mac is able or not to receive a new system version, by checking if the model is present in the official list that Apple publishes each year (see for example the list of Macs compatible with macOS 11 Big Sur).
  • The processor model and the amount of memory (Ram) installed, which indicates whether your Mac is powerful enough to run certain applications.
  • The name of the startup disk used for the system (macOS)
  • The Mac’s serial number. This number, which is obviously unique, is particularly useful if you call on Apple’s after-sales service.
  • To learn more about a category of Mac, consult the pages of the Apple support site which lists all the models by vintage with their official references.
