Routine maintenance for Mac OS X

Each system requires regular maintenance. This is not only to improve the system running speed, but also to maximize the system performance and save available disk space.

Now I will introduce several methods for maintaining the system.

Fix disk permissions:

In the [ApplicationProgram] There is a [utility] directory under the directory to find the disk tool, select the disk you want to repair permissions have two options, one is to verify the current permissions, the other is to repair permissions. The repair permission allows the system to restore all files on the disk to the correct permission configuration, so that operations cannot be performed due to permission issues during use, it is also designed to prevent malicious programs from modifying the system.

Disk repair:

If you are using a hard disk that has been damaged by a file system, you should pay attention to it, but don't worry too much. You can solve this problem by using disk repair tools. Find your Mac OS X system CD, use it to start the computer directly, and then run the disk tool. Select the disk you want to repair to fix it, many problems, such as crashes, can be completely solved by fixing disks. To ensure data security, you must always back up important data. Check the status of the current hard disk by the disk's S. M. A. R. T. Status.

Active maintenance:

By default, Mac OS X performs regular system maintenance after every day, mainly to clear useless logs and caches, and also to back up important system files. However, if the system is shut down or sleep during this period, regular maintenance tasks cannot be performed. This will not cause system problems, but maintenance can make the hard disk more available space.

In fact, you can select an active maintenance method to manually perform the maintenance. To do the maintenance, run the following command to proceed.

Sudo periodic daily

Sudo periodic weekly

Sudo periodic monthly

Update reinforcement:

If the system is very slow after the update operation or other operations, run the following command in terminal:

Sudo update_prebinding-root/-Force

After you press enter, enter the administrator password and press Enter. immediately restart the system when the $ sign is displayed after the operation is completed.

The above maintenance methods are recommended to be performed once a month. Of course, do not rush to reinstall the system in case of problems. The above operations may be quickly solved.
