Is your Mac up to date with the latest version of the Mac operating system (macOS or OS X)? Is it using the version required by some product or feature? Which versions are earlier (older) or later (newer, more recent) than the version currently installed? To find out, learn which version is installed now.
Mar 31, 2020 Expert Trick: When you're installing updates on your Mac, research the update version to make sure it's a good one. For instance, if you have 10.12.2 (macOS Sierra) or 10.13.1 (macOS High Sierra), your computer isn't going to run well. However, if you have 10.12.5 or 10.13.6, you'll be fine. Nov 02, 2017 I have found the rather strange behavior of the HD FaceTime camera at MacBook Pro 15' Retina with OS X Sierra and Parallels Desktop 12. Camera works perfectly with Face Time, Photo Booth and Skype if PD 12 does not launched. Patch Name: SkypeForBusinessInstaller-16.28.0.192.pkg: Patch Description: Skype for Business for Mac (16.28.0.192) Bulletin Id: MAC-064: Bulletin Title: Updates of Skype for Business 2015 for Mac.
If your macOS isn't up to date, you may be able to update to a later version.
Which macOS version is installed?
From the Apple menu in the corner of your screen, choose About This Mac. You'll see the macOS name, such as macOS Mojave, followed by its version number. If some product or feature requires you to know the build number as well, click the version number to see it.
This example shows macOS Catalina version 10.15 build 19A583.
Which macOS version is the latest?
These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Catalina. And as updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.
If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.
