Burning a bootable mac os disc on a PC. Making an OS X Lion installation USB disk from the command line

Home / Doesn't work

Which, according to Cupertino, thanks to new technologies makes Mac computers more reliable, functional and faster. A little later, the first beta version of macOS High Sierra was released, and today we will tell you how to create a bootable USB drive yourself to install this operating system on your Mac.

To do a so-called “clean” installation, you first need to create a boot disk, which can be used as a USB drive. This will allow you to install macOS High Sierra on multiple computers. In addition, you must have access to an image of the new desktop operating system. If you don't have a paid developer account, you can wait until the public beta version of macOS High Sierra becomes available or download its image from third-party resources.

Read the instructions to the very end before you begin the process of creating a USB drive with macOS High Sierra and its subsequent installation.

Requirements:

1. Computer * running OS X 10.7 Lion or higher.
2. macOS High Sierra installer downloaded to your computer.
3. USB disk with a capacity of at least 8 GB.

* Your computer must be compatible with macOS High Sierra - Mac compatibility list.

How to Create a Bootable USB Drive with macOS High Sierra

1. Download the macOS High Sierra installer. By default, the distribution is named Install macOS 10.13 Beta. You can rename it, but to avoid confusion, we recommend leaving this name. Make sure that the Install macOS 10.13 Beta file is located in the Applications folder (this is where all programs from your Mac are downloaded App Store). If it is located elsewhere on your computer, move it to this folder.

2. Connect the USB drive to your Mac. If it's not already formatted, run Disk Utility ( “Programs” → “Utilities” → “Disk Utility”) and format it by selecting "GUID Partition Scheme" and "Mac OS Extended (Journaled)". This process will erase all data from the USB drive.

3. You can choose any convenient name as the name of the USB disk, for example, “USB”. First make sure that there are no other drives with the same name connected to your computer.

4. Launch "Terminal" ( “Programs” → “Utilities” → “Terminal”) and enter the following command * :

sudo /Applications/Install\ macOS\ 10.13\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install\ macOS\ 10.13\ Beta.app --nointeraction

Once done, press the Enter key to move Install macOS 10.13 Beta to the USB drive and make it bootable.

* If you renamed the macOS High Sierra installer distribution or USB drive, edit the command to include your names. If the macOS High Sierra installer was not in your Applications folder, edit the command to its current location.

5. Enter your password (it does not appear on the screen) and press Enter.

This will begin the process of creating a bootable USB drive with macOS High Sierra. During the entire process, the USB drive will not be visible on the desktop. The process of creating a bootable USB disk will be accompanied in the Terminal window with the following text:

Erasing Disk: 0%... 10%... 20%... 30%...100%...
Copying installer files to disk…
Copy complete.
Making disk bootable...
Copying boot files...
Copy complete.
Done.

Once the files have been copied, your USB drive will appear on your desktop again and Terminal will tell you that the process is complete.

6. That's all! The bootable USB drive with macOS High Sierra has been created, you can close Terminal.

How to Install macOS High Sierra on Mac from a Bootable USB Drive

1. Connect your macOS High Sierra USB drive to your Mac.

2. Press and hold the Alt (Option, ⌥) key on your keyboard and restart your Mac. If your Mac was turned off, simply turn it on.

3. In the window that appears, select the bootable USB drive with macOS High Sierra as the boot drive. After this, a window will appear on the screen macOS installations High Sierra.

Despite the fact that Apple has provided the possibility of installing the system from hidden section on your hard drive, do not neglect the opportunity to burn the installation image to a DVD or flash drive and feel protected from any unforeseen situations. Plus, you won't have to spend at least$69 on , which only goes on sale in August.

To implement this plan, we will need Lion downloaded from the Mac App Store, a blank DVD or flash drive with a capacity exceeding 4 GB, and 30 minutes of free time. Also, be sure to make sure that you have copied all of the data from your chosen flash drive. important information(if there is one). So let's get started.

We go to the directory with installed programs, we find the application there Mac installation OS X Lion.app (if it is not there, you will have to download it again from) and select in context menu"Show package contents" item.

In the window that opens, you should travel through the internal directory structure and go to the SharedSupport folder.

We are interested in the first file, which is 3.74 GB in size. If you want to create bootable dvd, just take any application that can write DMG images and use it to write InstallESD.dmg to disk (just copy it at least to the Desktop first).

IN otherwise double-click on this file with the left mouse button and wait until the mounted image called Mac OS X Install ESD appears on the screen:

It's time to insert the USB flash drive into the computer and run Disk Utility, which is located in the Programs > Utilities folder. Now in the sidebar select our flash drive, and on the right - the tab Erase.

In the field Format type should be selected file system"Mac OS Extended (Journaled)", in the field Name enter something meaningful and press the button Erase. The formatting operation will take some time (depending on the size of the flash drive).

There is very little left to do - restore our connected InstallESD.dmg image to the USB flash drive. To do this, you need to select the flash drive again in the side menu and click on the tab Restore.

In the field Source drag the image icon called Mac OS X Install ESD, and in the field Purpose- our newly formatted flash drive.

That's it! Now, when the need arises, all you need to do is insert the flash drive into the USB port of your computer and, after turning it on, press and hold Option key(Alt) to select the boot partition.

You may be wondering which is better: burning a DVD or creating an installation flash drive? I think that the latter option is more acceptable, and for owners and new Macs mini doesn’t have to be chosen at all :)
