Updating the mac system
You will need to perform one of the Refresh Library methods below.By enabling the setting 'Update library on startup' the library will be scanned for new content each time Kodi is started.The only routine maintenance steps we recommend are the following: Check for updates to third-party software you have installed.Some third-party applications offer a preference to automatically check for updates.The following methods are available to scan folders and locate new titles to add to the Library.They can be performed on the entire library, a particular Source, or an individual title.Much dubious advice is available concerning "routine maintenance" of Mac® OS X.This FAQ, based on the "Maintaining Mac OS X" chapter of our book, Troubleshooting Mac OS X, is intended to provide guidance on recommended maintenance and to dispel some common maintenance myths.
This is primarily due to the fact that some poorly-written third-party installers have been known to change permissions on system-related folders, then failed to set them back, causing problems after the installation.
If you use NFO Files, new titles will be added to the library.
If you have changed the information inside a NFO File for an existing title in the library, this section will not update the library with those changes.
In some cases, such as System cache cleaning, they can have unintended consequences.
For this reason, we advise against enabling any automated maintenance features of third-party utilities other than a feature for running the standard UNIX maintenance scripts automatically. System and User cache cleaning are troubleshooting steps, not part of regular maintenance.
The Event Log will record any files missed when an Update Library is performed.
