The permissions repair feature has long been standard in OS X. Despite its ambiguity, Apple lets you run Disk Utility if necessary and check and repair permissions caused by software glitches. A new version operating system OS X El Capitan brings changes to this well-established process.
“I was shocked when I found out how much I had changed Disk Utility. I can't believe there is no way to check and repair the permissions or the drive. This is no longer a utility,” SelectGroup says indignantly.
IN in this case we're talking about about disk utility number 15, included with OS X El Capitan. Previously, it performed many important functions. For example, scanning system disk for damaged objects. Another important function was the management hard drives: formatting, partitioning, error correction. This functionality is no longer available. Mac owners"from the box".
But most OS X users probably won't notice the changes. According to statistical data, only a small part of Mac users used the function of restoring access rights.
If you are one of those who preferred to correct errors manually, we hasten to rejoice. OS X El Capitan has a built-in automatic file system scanning feature. It regularly checks the drive and eliminates any software glitches. By at least in theory.
This is what Disk Utility looked like in OS X Yosemite:
And this is what she looks like now:
A much more visual and therefore convenient demonstration of the distribution of data on the disk. In reality, Disk Utility represented of dubious value for working with files. According to Apple, it was almost a panacea for all problems. But in reality, it turned out that most of the damaged data remained unfound. Any specialized software from App Store offers much wider possibilities.
OS X El Capitan September 30. All Mac computers released in 2009 or later and some models released in 2007 and 2008 are compatible with the operating system.
The beauty of architecture Mac OS X the fact that the operating system itself is frozen in an ideal, uncorrupted state, is not subject to conflicts of system extensions, is not afraid of stupid users and other sources of disasters.
At least that's the theory. But what if troubles start directly with the hard drive?
Luckily, Mac OS X comes with a disk repair program
In the familiar Mac environment of icons and menus, it took the form of the Disk Utility program in the Applications-Utilities folder. In a desert world command line There is a utility that works almost the same, but is called differently - fsck (short for file system check – file system check).
Anyway Disk Utility(Disk Utility), or its alter ego fsck, is a powerful and useful tool, capable of curing all sorts of strange diseases, including the following:

operating system OS X Mountain Lion very self-sufficient, and to solve the majority necessary tasks You can use system utilities.
After purchasing a new computer, hard drive or installing and reinstalling the operating system, most users may think about the need to split the drive into several partitions.
Why is this needed and how can this be done using standard means OS X Mountain Lion, read this guide.
Using Disk Utility in OS X Mountain Lion, you can perform the following tasks:
-copy disks;
- burn disk images;
- create images of new disks;
- format partitions and drives themselves;
- treat sections and in sections with file system HFS+;
- resize existing sections V hard drives without formatting them, and much more.
When you first launch Disk Utility, you will see a standard main window with an extremely intuitive interface.
In the left column you need to select the hard drive or image that you want to work with this moment, after which you can begin to complete the task.
Deciding on the file system of the drive
Mac OS Extended is a standard file system for the OS X operating system. It is worth using such a file system on an external drive if you are going to use it exclusively in the OS X system, since on Windows recording it will be impossible. For use with Mac OS Extended Windows users will have to install special applications or driver. However, their use may eventually destroy the file system, after which formatting (deleting all files) from the drive will be required.
The main advantage of Mac OS Extended is its support key functions OS X, including Versions, as well as many others.
MS-DOS (FAT) - this file system is ideal for small flash drives, since it does not allow recording files larger than 4 GB. Remember this when formatting in MS-DOS (FAT).
Thanks to MS-DOS (FAT), you can use the drive in Windows, OS X, and even with such game consoles, like PlayStation 3, Xbox 360, and also Wii.
ExFAT - this file system is an updated FAT and allows you to work with files larger than 4 GB. The only downside to using it is the lack of support system functions OS X
Once you have decided on the choice of file system, you can safely proceed to formatting or partitioning the drives. I would like to give advice - on external hard disks, use Mac OS Extended, as it is the most stable and ideal for working with OS X.
Creating partitions on a hard drive or external drive
First, let's figure out why you might need this. So, hard marking disk is extremely necessary when using external hard large capacity disk. Let's say, when buying hard disk with a capacity of 2 TB, it is possible to create two logical partitions, one of which can be used to create backup copies V Time Machine , while the second one can store a media library for iTunes.
Remember that the partition size for Reserve copy at help Time Machine must be no less than that of systemic hard drive on which OS X Mountain Lion is installed. On average, if you do not back up your media library and other unnecessary multimedia files in Time Machine, for backup it is enough to use a logical drive partition with a capacity of 200-300 GB.
In order to divide the drive into several partitions, you need to select its main partition, as shown in the screenshot, and then go to the tab "Disk partition" .
At this point I have two partitions, since I previously divided the hard drive. You need to select the main section, you will only have one, and then click on the button «+» , which is marked in the screenshot.
After clicking, the drive will be automatically divided into two equal-sized partitions.
Attention! Do not exit the application and do not click “apply”!
After automatic layout, you need to set the correct size for each section.
To do this, click on the required section and type into the window "Size" the right volume for it. You can also adjust the section using the special slider marked in the screenshot.
After you have completed all these steps, you can safely click "Apply" and Disk Utility will begin partitioning the selected drive. In a similar way, you can create partitions in drives that contain some information.
When creating new partitions, do not forget to specify their correct size, and never disconnect the drive or turn off the Mac - this can lead to irretrievable loss data.
Checking and repairing the disk and access rights
Once every few months, especially if you are actively using your computer with OS X Mountain Lion and installing many applications, you should check your permissions as well as the hard drive itself.
To do this, you need to close all applications, open Disk Utility and select the system disk or partition, then open the tab "First aid" .
In this tab, click "Check access rights" and wait for the process to complete. If the window says that it is recommended to restore access rights, then click the button "Restore access rights" .
After this, check the disk by clicking on the appropriate button. If necessary and only if necessary, press the button "Fix Disk" .
What is it for? Some of the applications may change access rights to various system files, which leads to incorrect access to them. Restoring access rights allows you to avoid various operating system freezes, as well as some other problems.
Life-Hack - create a backup of the system disk using Disk Utility
Many people consider Time Machine to be the main backup method, but this is not at all surprising.
Time Machine lets you save copies of multiple versions identical files, has amazing functionality, great design and incredible user-friendly interface. Unfortunately, backup using Time Machine has one undeniable disadvantage - over time, the storage space begins to run out catastrophically.
That is why it makes sense to create a full backup using OS X Disk Utility.
To do this, you need to select the system partition or the entire hard drive if you have only one partition on it, then go to the tab "Restore" .
Now just drag the icon system partition in the column "Source" , and in the graph "Destination" please indicate external storage in a similar way. Remember that the backup copy will be completely identical in size to the system partition.
Now, if your hard drive fails, you can always easily restore OS X on any other computer.
To avoid rapid wear and tear on your hard drive or SSD, try to adhere to the conditions under which it is used and stored. Don't forget that standard hard disks incredible sensitive to falls and shocks.
“Rifat, I bought a new disk and I need to make it work on both Mac and Windows.” “Hi, I have a disk, but I can’t write anything to it on my Mac, what should I do?” “Listen, how to format Mac drive, so he ?".
My friends and clients ask me approximately these questions once a week, if not more often! So now, I will show you how to format a disk in disk utility, for different cases!
First, a short introduction to basic file systems (FS). If you don't want to bother with theoretical aspects, you can scroll below, directly to the formatting procedure.
To format a disk, you need to go to Disk Utility, which is located in the Programs - Utilities (Utilities) folder or find it through Spotlight. In the window that appears, on the left side, you need to select the disk to format - the disk itself, and not the volume name. In my case it is 160.04 GB Seagate TOSH..., not Extended HD. Next, we need to click on the Disk Partition button, at the top in the middle, and here we can see all the options for formatting the disk for different needs! So, now I will describe all the sections and what they give us:
1) Partition scheme - by clicking on “Current”, we can select the number of partitions on the disk. Someone may need to create a disk with 2 or more partitions for storage different files or for use on different computers.
2) Partition information - here you need to select the disk name and FS. For use on Mac and Win, select FAT or ExFAT. To use the disk for Time Machine, select Mac OS Extended (Journaled).
3) Options - by clicking on this button we select the type of bootloader - this is very important parameter, because It depends on it whether the disk will be detected on the computer or not!
— GUID Partition Scheme- no matter which FS you select, the disk will only be detected on a Mac with Intel processor(all modern poppies). Together with the HFS+ file system (Mac OS Extended), the disk will be available for creating backup copies via Time Machine! No other combination of the “Partition Scheme” and FS parameters will allow you to use the disk for copies!
— Apple partition scheme- designed for use in old Mac computers with PPC processor. We won't need it.
— Main boot record — when you select this item, the disk will be visible on computers with Win. But besides this, the format must be FAT or ExFAT.
ATTENTION! FORMATING A DISK ERASES ALL DATA FROM IT!!! BEFORE FORMATING A DISK, MAKE SURE THAT THERE ARE NO IMPORTANT FILES ON IT OR SAVE THEM TO ANOTHER DATA STORAGE!!!
After selecting all the parameters, you can click on the “Apply” button in the lower right corner and this will appear:
The system will warn you that all data will be deleted from the disk, and if you agree, then click on the “Disk Partition” button. Formatting is quite fast - from 3 to 20 seconds, depending on the disk size.
If you have chosen the path for creation of Time Machine, then immediately after formatting a window may appear asking you to select this disk for backups.
Let me clarify once again which items you need to select for:
— Time Machine and disk operation only with Mac- file Mac system OS Extended and GUID Partition Scheme;
— Disc for Mac and Win- file ExFAT system and Master Boot Record.
So we figured out how to format a disk in a Mac, and what options you need to choose for different cases! This method suitable for disks, flash drives, regardless of the connection interface - USB, FireWare or Thunderbolt. If you have any questions or difficulties in the process of formatting a Mac disk, write about it in the comments :)
