Mac os x boot caches updating

This practice should significantly minimize the potential for data loss to new data or changes to existing data since the last backup was performed.

Note: It is VERY important that you do not use versions of software utilities mentioned on this site that the developer has not approved for use with your version of OS X (that is, OS X 10.8, 10.9, etc.) I've created this site because so many Macintosh users have expressed frustration that they don't know how to perform routine maintenance on their Macintosh computer.

Hard drive failures, bad sectors, and directory corruption are serious problems as these can result in data loss.

If you value your data, you have implemented a comprehensive Backup and Recovery solution and use it regularly, preferably backing up everything on a daily basis.

What we observe is the App Store app showing a spinning beachball “forever”, even between force quitting and restoring the App Store app. Here’s how: By whatever means, force quit App Store.

When you click on the “Update” buttons, nothing happens. The screenshot above shows using Activity Monitor to do it, but you can also do it via Terminal, or by pressing and holding the icon in the Dock while pressing the Opt key, then using the popup menu’s “Force Quit” command.

In OS X 10.9 or higher, this command requires an administrator password, hence the use of sudo.

Go ahead and type your password in—Terminal won't show your password for security reasons.

While directory corruption does not necessarily result in file corruption, certain types of directory corruption, such as overlapped files or extents, can result in file corruption and hence data loss.
