How To Determine Your macOS Version on Your Mac

Figuring out which version of macOS you’re running isn’t always straightforward, especially if updates get missed or if you’re dealing with apps that only work on certain OS versions. Knowing your current macOS version helps decide if you need to update or troubleshoot compatibility issues. Luckily, checking it isn’t complicated, and there are a couple of ways that are pretty reliable. Expect a quick glance at either System Information or System Settings—both give you the details you need. Sometimes, it’s just about making sure your Mac’s running the latest so everything plays nice and secure. And yes, sometimes it feels like macOS keeps you guessing—because, of course, Apple has to make it a little harder than necessary. But with these steps, you’ll have the info in no time.

How to Check macOS Version You’re Using

You can check your macOS version using System Information or System Settings. Here’s how to do each one, step-by-step.

Using System Information

Quick and reliable, this shows the macOS version along with details about your hardware. This is handy if you want to see everything in one place or are troubleshooting something more technical. When you check the System Information, it’s basically giving you the unvarnished truth about your Mac’s setup.

1. Make sure your Mac is turned on and unlocked.
2. Click the Apple logo in the top-left corner. From the menu, select About This Mac. On some macOS versions, this link will take you directly to a window with the version info, but on others, it’ll open System Information instead (you might see an option labeled System Report the first time).
3. If it opens System Information, look for the line that says Software Version or check the top of the Overview tab for the macOS name (like “Ventura”) and version number (like “13.4”).

This method is kind of weird but effective because it gives you both the OS details and hardware info all in one go. Sometimes, on older Macs, the About This Mac window is more straightforward, but the system report is good for getting the detailed version info if you need it.

Using System Settings

This is the more modern method—less technical, more visual. It’s what most people use now since System Preferences (or Settings) have been revamped in recent macOS versions.

1. Click the Apple logo in the top-left corner.
2. Select System Settings from the menu.
3. Once the window opens, click General on the sidebar, then choose About.
4. Look under the macOS section — you should see the name (like Ventura or Monterey) and version number (like 13.4) right there.

This way is super quick and cleaner, especially if you’re already poking around in Preferences. Honestly, if you’re just checking what’s installed, this method is easier and might be enough in most cases, especially on newer Macs.

How to Update macOS on Your Mac

If it turns out your Mac isn’t running the latest version, updating is the next step. It’s generally straightforward, but sometimes, the update process stalls or refused permissions. Usually, just one or two clicks and some patience will do it. An older OS might mean missing out on security patches or new features, so keeping it up-to-date is a good idea.

1. Click the Apple logo and select System Settings.
2. In the sidebar, click General, then find and click Software Update.
3. Let your Mac check for updates. If a new version pops up, hit Update Now or Upgrade Now.
4. If prompted, enter your login password or Apple ID credentials.

Sometimes, the update process might fail on the first try, or you might see error messages about storage space or network issues—I’m looking at you, Apple. If that happens, a quick restart or freeing up some space sometimes helps. Also, check your Wi-Fi connection—because of course, macOS has to make it harder than necessary sometimes.

For more info on the latest macOS versions, head to Apple’s official list of latest macOS releases. It’s always good to have that page bookmarked in case the update doesn’t show up for some reason.
