Humans are creatures of habit. And if you use computers, there are some habits that you MUST develop. Obviously, backing up all of your data is first and foremost. Then you have maintainance. Removing duplicate files, for example, to make for more hard drive space.
But other under the hood jobs include clearing out and cleaning up cache files, running cron jobs, repairing permissions and such. But your average user (family members come immediately to mind) can cause themselves lots of trouble due to lack of knowledge as how to perform such tasks. If only there was an app that was quick and easy to use.
“Yasu is a Macintosh application which allows users to easily run many of the system level Unix shell scripts that perform maintenance routines as well as clearing many of the cache files used by OS X.
Yasu was developed as a user friendly, simple, first line of attack for a Mac that has started misbehaving. Often, a thorough purge of the system cache files on a Mac will solve odd behavior.”
And after a brief development hiatus, Yasu has been upgraded to to work with Mavericks.
THE JUICE
Yasu is an acronym for “Yet Another System Utility.” It was developed by IT professional Jim Mitchell to save himself time when cleaning up machines that he maintained at work. Yasu allows you to accomplish with the click of a single button what would take some time using terminal commands.
THE PULP
Download. Install. Select from over two dozen or so actions that you want performed. No terminal, just a single click! And I can honestly say that it has never failed me over these many, many years!

It’s now one of my daily habits. Every time I choose to shutdown my MacBook Air, I run Disk Utility and finally, Yasu. Now, everything is nice and clean when I boot in the morning.
THE RIND
I couldn’t remove the “nag screen.” I’ve been a long time user who donated a long time ago and was hoping to bypass this little inconvenience. But I got a hold of Jim and he straightened me out immedately. (Obviously, because I had been upgrading for years, to remove the “nag screen” from the new Maverick’s version I needed to trash the old .plist. DUH!)
SUMMARY
As much as Mac is the computer “for the rest of us,” there has always been some necessary maintenance that needed to be performed. As it has grown UNIX under pinnings, there is even more to take care of. Even if you’re not a power user. Yasu can help you lighten that load.
RATING: 5 outta 5
