![]() There is no need to hold down the Shift key past the time that the spinning bar cursor appears. I recommend that you occasionally restart your Mac, and hold down the Shift key right after the startup chime is played, and keep it held down until the spinning black bar cursor appears. OS X doesn't do any drive defragmentation at all. "ACL found but not expected" or “Warning: SUID file” error messages In addition, often the curative effects of repairing permissions are repeatable and predictable. ![]() The reality is that Repairing Permissions doesn't require that you purchase anything to do it, it can be accomplished fairly quickly, it doesn't hurt anything, and after repairing permissions sometimes the problem(s) that the user is experiencing are gone. ![]() While repairing permissions isn't a panacea, they are wrong, it is definitely worth your while to repair permissions occasionally. Additionally, no authentication dialog will appear when you click “Run” (or hit the “Return” key).Maintenance Myth #2: There are some folks who are very adamant that you never need to repair permissions under OS X. ![]() If you are logged in as a non-admin level account, you’ll only be allowed to perform the standard user options. Enter the password for the current administrator account and click “Okay” (or hit the “Return” key). Once selecting which options you want to run and hitting the return key, if you’re logged in as an administrator, you’ll be prompted with an authentication dialog. Instead, each task is right there to be selected in one window, ready to be run when you say go. Tasks aren’t spread out across several tabs for a user to switch back and forth between. I intentionally developed Yasu to only contain the tasks that are most crucial to maintaining system health - and all in one window. Tweaking some obscure Finder setting really doesn’t matter when it comes to keeping your Mac healthy. But that’s just it, sometimes that “then some” is way too much for the average user. There are several similar utilities to choose from that do the same things as Yasu, and then some. One of the questions I get asked most is “Why should I use Yasu instead of one of those other utility applications?” It’s a very legitimate question. While Yasu works quite well on its own for certain things, it should be used in conjunction with other utilities, such as DiskWarrior or TechTool Pro, in order to keep your system in optimal health. Yasu is not a solution for total system maintenance, and is not a replacement for the Unix ‘cron’ or ‘launchd’ daemons. Yasu was designed to be a simple, first line of attack for a workstation that has started “acting up.” More often than not, a thorough purge of the cache files of a Mac will bring its behavior back into line. Yasu is a “Universal Binary” Macintosh utility built using AppleScript Studio that allows system administrators, as well as standard users, to conveniently run various system level Unix shell scripts in order to perform maintenance routines and clear the many cache files used by OS X. Created with System Administrators who service large groups of workstations in mind, Yasu (Yet Another System Utility) is a Mac OS X maintenance utility that has been developed to do a specific group of tasks quickly within a few clicks, rather than needing to endlessly type shell script commands in the Terminal application.
