![]() OS X is designed to make basic maintenance tasks invisible to you. When: You don’t have to lift a finger-the scripts run daily, weekly, and monthly, as long as your machine is awake at their scheduled run times. They delete and archive unnecessary data created through normal use of your machine. Why: OS X comes with a set of Unix scripts that run automatically. The preceding command works on 10.3 systems, but it shouldn’t be necessary.įor another way to speed up application launch times, see “To Defrag or Not to Defrag?” Automate Your Maintenance For programs that are either drag-installed or installed on other volumes, the system automatically runs a tool called fix_prebinding when it detects an application with outdated prebinding information. In OS X 10.3 and later, the system automatically updates prebinding information whenever you use Apple’s installer program to install a program on the boot volume (the “optimizing” step you see during the install process). You may want to do this at the end of a workday-the process can take as long as an hour, depending on how many applications are installed. ![]() Sudo update_prebinding -root /, and enter your admin password when prompted. Your Mac automatically re-creates it the next time the system or the program needs to write something to the log. After you confirm your action, that log file vanishes. In Console, delete any log listed in your user folder’s Library: Logs folder by highlighting it from the left-hand Logs column and pressing Command-delete. To root out log files at the user level, you need either the Console application (in Applications: Utilities) or an application such as NoName Scriptware’s CacheOutX. You can run OS X’s built-in daily, weekly, and monthly maintenance scripts to take care of the system-level log files. Like cache files, log files are stored in several places, from the system level (in the /var/log and /Library/Logs folders) to your user folder (~/Library/Logs). Large log files don’t cause system instability, but when diminishing disk space becomes a concern, there are a couple of ways to clean up. Who: Users concerned with freeing every bit of available drive space, and users who make extensive use of FTP, Web, and other bundled Unix applications.Īs you work, your OS and applications automatically create log files that record everything from the mundane to the important. Lets you view log files and browse Unix main pages. Lets you run Terminal commands Finder tweaks. Lets you manage login items and tune Internet connection. Lets you schedule cache removals via iCal events. Lets you enable Dock shadow alternative genie mode Finder tweaks. Lets you set how often to monitor and set notification method. Intelligent scheduler runs scripts during idle time.ĭisplays scripts’ output in its window as they’re run Rebuilds directories and saves data from damaged disks ![]() Repair Disk Permissions uses internal data, as well as data in the top-level Library: Receipts folder, which keeps track of software you’ve installed. ![]() “Even Perfect Disks Have Imperfect Permissions.” ) When it’s done, any permissions issues that affect system-level files and folders on your machine will have been resolved. This process can take as long as 15 minutes while Repair Disk Permissions is working, you’ll see messages about items it has corrected. ![]() (Don’t bother running Verify Disk Permissions-it takes just as long as Repair Disk Permissions, and if it tells you that it found permissions errors, you’ll then want to run Repair Disk Permissions anyway.) To repair broken permissions, launch Disk Utility (Applications: Utilities), click on your startup disk, and then click on Repair Disk Permissions. This happens most often after you install software that includes system-level components, or when you update the OS. Although OS X’s permissions system works well most of the time, default permissions can become corrupt. Different files and folders at different locations on your hard drive have different permissions. ![]()
