We present to your attention another portion of tips on how, using simple commands in the Terminal, you can make changes to the system, open settings and enable functions that are not available in other ways. Some operations will seem fun, some will seem quite complicated, but all of them serve only one thing - to make working with Mac OS X and some other applications even more comfortable.

We remind you that when working in the Terminal you should be careful with commands that start with sudo . These are system-level commands that, if used incorrectly, can cause serious problems in Mac OS X, even crashing the system. Therefore, these commands must be entered as carefully as possible and exactly as indicated in the instructions. Typically, when working with such commands, you are required to enter the administrator password, which is entered blindly.

CLEANING MAC OS X

For some this will be a secret, for others not, but Mac OS X has a self-cleaning feature. Absolutely without user intervention, the system cleans itself, removing various temporary files and other garbage. There are three levels of cleaning - daily, weekly and monthly. Each type of cleaning is carried out strictly according to schedule, at the same time set time, usually at night. So, for example, daily cleaning occurs every day at 3:15 am, weekly cleaning occurs every Saturday of the week at 3:15 am, and monthly cleaning occurs every first day of the month at 5:30 am. But there is one feature - automatic cleaning is performed only if the Mac was turned on at a specific time. If the computer was turned off, the cleaning session will be delayed.

• Unscheduled launch of the self-cleaning system in Mac OS X

There is no need to wait for the next scheduled auto-cleanup or leave the computer on all night. Using a few Terminal commands, you can independently perform an unscheduled auto-cleanup of the system. To do this, open the Terminal and enter:

sudo periodic daily
sudo periodic weekly
sudo periodic monthly

It is not necessary to enter all three commands and perform all three types of self-cleaning at once; you can, for example, limit yourself to one or two cleanings.

After self-cleaning is completed, you will need to restart the computer, and this can be done directly in the Terminal, without having to reach for the “apple” with the mouse.

sudo reboot

• Cleaning extensions and system cache in Mac oS X 10.6.x.

It may be necessary if strange glitches related to system drivers occur. We enter the indicated commands one by one, not forgetting to press after each RETURN:

sudo rm -rf /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext
sudo rm -rf /System/Library/Caches/

Then we correct the access rights (of course, this can be done in Disk Utility, but why do we need to open several applications at once):

sudo diskutil repairpermissions /

When uninstalling applications through additional software, you can get rid of unnecessary directories that the system itself can skip.

Memory cleaning programs are downloaded through the AppStore. Programs such as CleanMyMac, AppTrap or OmniDiscSweeper can help clean up disk space. Some programs are provided completely free of charge, but there is also paid software.

DaisyDisk can become good addition to any of the utilities listed above.

It so happened that even in 2018 the MacBook hard disks very small volume. Regardless of model Mac use- the free space is melting before our eyes. We offer 8 ways to help free up precious disk space. Let's say the storage is already full, or even worse, a notification has arrived that there is no free space.

1. Remove unnecessary items from the cart

The first thing you need to do is “take out the trash,” no matter how funny it may sound, empty the trash. The Recycle Bin on a Mac works similarly to the Recycle Bin on Windows; instead of deleting it from your hard drive, files are first moved to the Recycle Bin so they can be recovered. Regularly empty the Recycle Bin of unnecessary files; do not forget that some applications, such as Mail or iMovie, have their own Recycle Bin, which also needs to be emptied periodically.

2. Remove unnecessary applications

Some applications take up a lot of space, review the list of installed applications and remove those that you do not plan to use. To see the list installed application and the amount of storage they take up - open Finder, go to Applications, then select "Display items as icons, list, columns, or Cover Flow."

3. Delete iPhone or iPad backups from iTunes

If you often synchronize your iPhone or iPad with iTunes, a bunch of backup copies are collected on your hard drive, which take up a lot of free space. To find backups, use this path:

~/Library/Application Support/MobileSync/Backup

There, all backups will be signed with random names. Delete them all, then create a new one if necessary. backup copy iPhone or iPad.

4. Delete temporary files

A lot of temporary files accumulate on the macOS hard drive, which are not particularly valuable, as a rule. operating system periodically deletes these files itself, but does not do this as often as we would like.

Periodically delete temporary browser files; these files speed up the loading of web pages, but sometimes browsers store unnecessary files, and deleting them can free up storage.

Temporary macOS files can be found by opening Finder, click Go, then Go to Folder, use the path

A folder with temporary files will open, which can be deleted without harm to the operation of macOS.

5. Remove language packs

operating room macOS system comes with pre-installed language packs so that you can switch the system language to the desired one at the right time. Often 1-2 languages ​​are used, which means unnecessary ones can be deleted, freeing up space on your hard drive. You can remove unwanted language packs using the CleanMyMac or Monolingual apps.

6. Remove large email attachments

Users of the pre-installed Mail app may end up with a lot of emails with heavy attachments. Check the already downloaded emails and delete unnecessary ones. To save space in the future, automatically download attachments in the Mail application settings.

7. Remove junk from the “Downloads” folder

This is advice from Captain Obvious, but it is often forgotten. The “Downloads” folder is a garbage dump of downloaded files, open it and delete what you don’t need.

8. Removing junk using a special utility

The easy way was left for dessert. The above steps can be performed more easily using a special utility, such as CleanMyMac. MacPaw's utility can automatic mode perform the necessary actions to clean your Mac, and also provides the ability to remove language packs in a few clicks, correctly uninstall applications, clear browser caches and email attachments.
