用命令升级mac OS 效率更高199@365

如果用app store升级mac失败，请用命令行命令升级。

To get a list of available software updates, type the following command:

softwareupdate -l

You can then install all available software updates with the following command:

sudo softwareupdate -iva

ou can also install only the recommended updates with:

sudo softwareupdate -irv

Or you can just install specific software updates by specifying the shorthand package name from the previous list, like so:

sudo softwareupdate -i iPhoneConfigurationUtility-3.2

If there are any updates you want to ignore, you can do so with the –ignore flag, for example:

sudo softwareupdate --ignore iWeb3.0.2-3.0.2

If you want to see all the available command line shortcuts for Software Update, just type:

softwareupdate -h
