If you downloaded an ISO image of a third-party system, such as Windows 10 or Ubuntu to your MAC and want to copy it to a USB flash drive, then at a certain point will come across the problem.
One way to help copy the image to an external medium is the use of the terminal. We will describe this material about all the features of this method.
The main snag that may occur is related to the Sudo command. First, it requires a mustache administrator password. Secondly, due to the specifics of the work of the command, the incorrect user actions can damage and loss of copied data.
Before copying, make sure that all the names of the flash drive and image correspond to those that are recorded in the team. The correspondence must be complete, otherwise Mac will erase other data. Also, all information on the USB drive will be automatically removed and the ISO image of the system will be recorded on top. Neither requests nor confirmations will be.
1. Connect the USB flash drive to the computer.
2. Run the terminal.
3. Enter the following command:
4. The command will display all the devices connected to the Mac approximately in this form:
$ diskutil list
/ dev / disk0
#: Type Name Size Identifier
0: guid_partition_scheme * 251.0 GB Disk0
1: EFI EFI 209.7 MB Disk0s1
2: Apple_Corestorage 250.1 GB Disk0s2
3: Apple_Boot Recovery HD 650.1 MB Disk0s3
/ dev / disk1
#: Type Name Size Identifier
0: Apple_HFS Macintosh HD * 249.8 GB Disk1
Logical Volume ON Disk0s2
Unlocked Encrypted.
/ dev / disk3
#: Type Name Size Identifier
0: Partition_scheme * 5.3 MB Disk3
1: Partition_Map 32.3 KB Disk3S1
2: Fat_32 The_Destination 8.2 GB Disk3S2
/ dev / disk4
#: Type Name
5. In this list, find your USB drive by name, which in our case is called the_destination.
6. Pay attention to the device identifier, in our case it is disk3s2. Write it down in order not to lose.
7. Run the following command:
sudo Umount / Dev / Identifier
Insert the desired parameter to the identifier, in our version the command will look:
sudo DD if \u003d / image.iso of \u003d / dev / Ridency BS \u003d 1M
The command needs to substitute its parameters. Not only the identifier, but also the path to the image, as well as its name. Example:
sudo dd if \u003d ~ / desktop / windows10_x64_en-us.iso of \u003d / dev / rdisk3s2 bs \u003d 1m
Pay attention to the R parameter before the identifier and BS \u003d 1M after it. They are not required for the copying and recording process, but significantly accelerate this process.
10. If you entered all commands correctly, you can press ENTER.
11. The system will require an administrator password entry, after which the copy process will be launched.
Note that the lines of progress will not be. The speed of copying and recording is also not constant and will depend on many parameters, including Mac performance, flash drive speed and so on. Upon completion of the process, you can turn off the drive and proceed to its use as a boot.

It's time to write another useful instruction for Mac users. Today I will show you how to create a boot USB flash drive with Mac OS X Installer.
Why do you need it? Well, situations where you can apply such a flash drive there are more than a few. Suppose your old hard drive "flew" (God forbid), and now you want to install the system to a new hard disk, or you just want to install the system at once to several computers, or you need to perform a "clean" installation of OS X. Well, same your option ...
Let's be proceeding to the process itself.
Create a boot flash drive with an OS X installer is not at all difficult. And the paths for this there are also several.
For a variety, I will give two options for your choice. Choose any ... at your discretion, well, or the level of advancement.
Minimum requirements:
- The first thing we need is a flash drive itself. Minimum amount of 8GB (be prepared that you will lose all data from this drive during formatting). The drive can be any ... Even external railway
- Downloaded from Mac App Store Installer OS X in Format.App
Download Installer OS X
First of all, we need to download the installer OS X. We are now specially not tied to a certain version of OS X, because Each year Apple releases an update.
The old version of the operating system almost immediately becomes inaccessible to download from the App Store. At the moment, the current version is OS X 10.11.3 EL Capitan. Therefore, download the file with the installer on the link below.
Downloaded by installer Install OS X El Capitan.App"It has a size of 6.2 GB and the default is placed in the folder Programs (Applications).
Create a bootable USB flash drive with an OS X Installer
And here for your choice, as I promised, two ways to solve our problem are presented:
- The first method, as for me, the simplest and fully automated (involved third-party software).
- The second implies some actions on your part (not required to install third-party software).
Method number 1: Use the DiskMaker x 5 application
To create a boot USB flash drive with an OS X installer, good people have created a special application - Diskmaker X.. It is completely free and fully automates the process of formatting and transfer the installer to USB media. A brief instruction is shown below.
Step 2 - Run the DiskMaker X application and in the window that opens, select the version of the operating system we want to upload to USB media. In our case, it is El Capitan.
Step 3 - Next will follow a couple of steps, where you need to confirm the location of the installer itself (folder /Programs) And which carriers require it to write. Follow the tips on the screen and agree where it is necessary.
The process of creating a bootable flash drive with OS X takes about five minutes, so be patient. After the process is completed, the appropriate message will appear.
To use the boot flash drive, you must restart the computer with the Option (Alt) button, and select USB media from the download manager.
Method number 2: We use only state funds OS X
This method is a bit more complicated and longer, because We will do everything manually. Follow the instructions below.
Part 1: USB Preparation Media
Step 1 - Insert the USB flash drive and run the disk utility. Then click on the left side of the window named this flash drive. Once again I remind you that the flash drive must be a volume of at least 8 GB.
Step 2 - Select the " Erase"And in a string Format Specify Mac Os Extended (Journaled). Click the erase button ... and confirm your intentions again.
Step 3 - Click the " Disc section" Expand Menu Section scheme and select Section 1.
Step 4 - in the field Name Enter untitled. (This is important, because In the next part, we will access the USB media by this name).
Step 5 - Click the Settings button ... and select item GUID section scheme (It is necessary to copy system files to USB media). Confirm clicking OK.
Step 6 - After that click on the Apply button. When the USB preparation process is completed, close the disk utility.
Our flash drive is ready! Now it remains to transfer the OS X installer, downloaded earlier. This is more detailed in the second part below.
Part 2: Transfer OS X installer to USB media
Step 1 - At the very beginning of the article, you had to download the installer OS X EL Capitan. If you still have not done so, come back and download. As a result, the downloaded installer "Install OS X El Capitan.App" (size 6.2 GB) must be in the folder Programs.
Step 2 - Run Terminal And run the following command (so as not to make a typo, simply copy and paste the text below):
sudo / Applications / Install \\ os \\ x \\ el \\ capitan.app/contents/resources/createInstallMedia -Volume / Volumes / Untitled -ApplicationPath / Applications / Install \\ OS \\ X \\ EL \\ Capitan.App
If you can't run this command in the terminal, and instead issues a message " command Not Found"So you immediately indicated something wrong.
In my case, I incorrectly indicated the name of the installer, which ultimately should be like this: Install \\ OS \\ X \\ EL \\ Capitan.App ( before each space in the file name in the terminal, you must install a reverse slash).
Step 3 - Enter the administrator password when you are asked ( in the terminal window, your password will not be highlighted, and it will seem that you don't dial anything at all - it should be). After you click Enter, you will be asked to clean the media USB cleaning - enter the letter Y. And once again press ENTER.
Step 4 - In the window Terminal The process of creating a boot USB flash drive will begin with OS X EL Capitan. The USB flash drive will rewn the boot files and the OS X installer itself.
Step 5 - After successfully completing the process, close the window Terminal. To use the flash drive, restart the computer with the Option (ALT) button and in the download manager, select Replaceable media.
Something like that! The first method of creating a boot USB flash drive with OS X was much easier, but the second method does not particularly strain, although it has to work a little handles. As always, the choice is yours.
Well, as usual, I start to miss you feedback…
