Osx Upgrade To Catalina

Is your Mac up to date with the latest version of the Mac operating system? Is it using the version required by some product that you want to use with your Mac? Which versions are earlier (older) or later (newer, more recent)? To find out, learn which version is installed now.

从 macOS Catalina 10.15 或 Mojave 10.14 升级？ 前往'系统偏好设置'的'软件更新'，找到 macOS Big Sur。点击'现在更新'并按照屏幕指示开始升级。 从较早版本的 macOS 升级？ 如果你的设备运行的是 macOS 10.13 至 10.9 之间的任意版本，可从 App Store 升级至 macOS Big Sur。. This is specific to iTunes. ITunes does not run in Big Sur or Catalina, instead the Finder manages the iPhone on the newest releases. To copy ringtones to iPhone from MacOS Catalina and macOS Big Sur, you can drag and drop the.m4r ringtone file directly into the main ‘Sync' window of the connected iPhone. That should work fine. 从 macOS Catalina 10.15 或 Mojave 10.14 升级？ 前往'系统偏好设置'的'软件更新'，找到 macOS Big Sur。点击'现在更新'并按照屏幕指示开始升级。 从较早版本的 macOS 升级？ 如果你的设备运行的是 macOS 10.13 至 10.9 之间的任意版本，可从 App Store 升级至 macOS Big Sur。.

Note: This same script works for Big Sur, Catalina, Mojave, and High Sierra. You are all set! 🙌 (OPTIONAL) Use this macOS VM disk with libvirt (virt-manager / virsh stuff). Edit macOS-libvirt-Catalina.xml file and change the various file paths (search for CHANGEME strings in that file). The following command should do the trick usually.

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 should see the macOS name, such as macOS Big Sur, followed by its version number. If you need to know the build number as well, click the version number to see it.

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 Big Sur. 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 that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.
