(Sorry for the inconvenience)
PC-BSD 9.0 introduced a redesigned Update Manager to make it easy to update the underlying FreeBSD operating system, installed PBIs, and system components and to apply security updates. Unlike previous versions of PC-BSD, the 9.x series of PC-BSD uses the GENERIC FreeBSD kernel in order to facilitate upgrading the operating system itself.
Update Manager provides an easy to use GUI which is described in this section. However, advanced users can use the following command line utilities to achieve the same results:
- pbi_update: used to update installed PBIs
- pc-metapkgmanager: used to update installed system components
- [[ | pc-updatemanager]]: used to update the operating system
An icon located in your system tray lets you tell at a glance if any of your PBIs are out-of-date or if a system update is available. This icon has several possible states:
newer versions of installed PBI(s) are available; click this icon to open AppCafe® so that you can update the PBI(s).
If you right-click the icon, you will see the menu shown in Figure 6.3a. If updates are available for installed PBIs, AppCafe® will also open to the Installed tab so that you can view the new versions which are available.

Selecting "Start the Update Manager" from the right-click menu will open Update Manager so that you can review the available update(s).
Figure 6.3b shows a screenshot of Update Manager:

If any updates are available, they will be listed; if your system is fully up-to-date, there won't be any entries.
If you hover over a listed update, a pop-up menu will provide some details about the update.
To install an update, check the update(s) that you wish to install and click the "Install selected updates" button. You can watch the update's progress as seen in Figure 6.3c:
Figure 6.3c: Installing a System Update
If the update requires a reboot, you will be notified to do so after the update has been installed. If a reboot is needed, clicking the OK button at the informational message won't reboot the system. Update Manager won't automatically reboot, meaning you can continue to use your computer for other tasks while the system is being updated. Finish whatever you are doing and reboot the computer at a time that is convenient for you.
You can see which updates are available, which have been ignored, and which have been installed by looking at the contents of those subdirectories within /var/db/pc-updatemanager. Each update ends in a .upd extension. A .upd file contains information about the update, as seen in the following example:
