How to make a Mac OS X bootable USB installation media. Before you can use TransMac, you may first need to partition your USB flash drive with a GPT partition, as a normal MBR partition may not work. To do this, you’ll need to use the Diskpart command-line utility on Windows. Open Command Prompt with administrative permissions. I was never able to write a Mac installer image to my Flash Drive and have it bootable, unless I did it on a Mac. Using Michael D. Dryden's Link, I was able to use the Diskpart command to clean and prep a GPT partition on a flash drive for an OSX Mavericks install image.
In addition to macOS, Apple has released macOS high sierra. MacOS High Sierra is the successor of macOS sierra. With it’s every release apple updates macOS with new features, new design, better security, more stability and better performance. As you know any of the macOS cannot be officially installed on any non-apple hardware, because of this reason installing macOS on PC was never an easy job. In this article, I will show how to create a bootable USB of macOS high sierra on windows 10.
Downloading the required files. Download the macOS high sierra DMG file from this. Download Transmac from their official or you can download it directly from.
In this tutorial, I am going to use the Transmac software to create the bootable USB drive from windows. Transmac is a paid software, however, it offers 15 days of trial which is enough for you to create the bootable USB. Installing Transmac. After downloading the setup.exe double-click it to open and follow the procedure displayed in the setup to install. See also: Step 3. Making the bootable USB drive. In order to make bootable USB of macOS high Sierra, you will need an 8gb or higher USB 2.0 or USB 3.0 drive.
Note: By using USB 3.0 you might face some issues while booting into the installer, in that case, please try using USB 2.0 drive. Insert the USB drive into your computer and then right click on the transmac app and select “run as administrator”. Running as administrator is required as we will format the USB drive through the transmac app. Now right click on the USB drive you inserted and click “Format for mac”. Note: This action will format the drive and the data inside the drive will be lost, so before formatting the USB drive, please make sure that the drive you selected is your removable USB drive, not any other drive and also make sure that you backup all the data to a separate drive. After the formatting is done again right click the USB drive and click “Restore with Disk Image”. Click “yes” on the warning about erasing data, then click on the select file button and select the macOS high sierra dmg file that you have downloaded earlier and click OK.
Now it’s time to sit back and relax as the process will take time to complete. After the progress bar is finished, your bootable USB of macOS high sierra is ready. Note: After the USB drive is formatted as mac or the dmg is restored successfully windows will give you an alert to format the drive due to incompatible file-system, but don’t click format otherwise you have to start over again. See also: Step 4. Installing macOS high sierra.
Before we try to boot the macOS installer we need to make some changes to our BIOS settings. Just to spoof the macOS installer so it thinks that we are booting the installer from a real mac, else we will face a disabled boot screen or a message saying “macOS cannot be installed on this device”. Reboot your PC and just after you see the manufacturer logo quickly press the “F2” button or press it several times until you see the BIOS menu. To boot into the BIOS settings menu. Change the following settings:-. SATA mode: AHCI. CMS support: Enabled.
Secure Boot: Disabled. Virtualization: Disabled (optional, I haven’t faced any issues keeping it enabled till now but might cause one in some hardware). DVMT Pre-allocated: 64 MB or Highest. DVMT Pre-allocated option is to set the internal GPU memory. Most laptops come with 32mb fixed allocated memory, it causes an error while booting into macOS sierra or Higher versions on Intel skylake or higher architecture CPUs.
It is not a common option and might not be available in your BIOS settings. Setting it to 64mb or higher eliminates the need of applying miniStolen patch.
Now after changing the BIOS options, plug in the bootable USB drive and power on the machine. Now again boot into BIOS by tapping “F2”, and open the “boot menu” and select your bootable USB drive from the “Boot drive” menu. If you selected the correct drive in the above step, you should see the clover boot menu. In the clover boot menu select the “Install macOS high sierra” drive and tap “Spacebar” and check “verbose” option and click “Boot with selected option”. Booting verbose will allow you to see if any error occurs while booting. After successfully booting into the installer, select your preferred language and click next and then from the macOS utilities screen select “Disk Utility” and click continue. Here, select the partition in which you want to install macOS.
As the partition will be formatted, make sure it is empty. And also make sure the size of the partition is at least 15GB, I prefer to make the partition of size 40Gb or higher so I don’t have to resize it later. Now click on erase and then name the partition as you like, then from the “Format” drop-down menu select “APFS” and click erase. After formatting the partition, close the disk utility app and select “Install macOS” and click continue.
Here you will be asked in which partition you want to install macOS High Sierra, select the partition you formatted in the above step and finally click on install. Happy Hackintoshing ? if you get any trouble please feel free to post in comments.

How to create a bootable Windows 10 USB on Mac 09 June 2017 on, The last release of Mac OS doesn't have the option to create a bootable USB from Bootcamp like previous versions, and it is a problem because that require uses other tools. I am updating this post today Dec 12, 2018. The reason is that I was only using to create the bootable USB, I will leave guide as a second method since it still working, and I will explain to you how you can create the bootable Windows USB without extra software. The first step for both methods requires to format your USB device to ExFAT. Format USB to ExFAT In order to boot from the USB, you need to format the USB to ExFAT, you can do it using Disk Utility (it comes with MacOS).
This step is the same for both methods. You need to show all the devices in Disk Utility' before to start the process. Select your USB device in the list (not the partition), right click and then click on the Erase option: In the next screen make sure you select these two options:.
Format: ExFAT. Scheme: Master Boot Record Click the Erase button.
If for some reason it fails, probably is because MacOS still using the USB, just repeat the steps, but if you see a screen similar to above screen is because the operation is successful. Format USB with the terminal You also can format the USB from the terminal, but you have to take care to use the correct device because, if you use the wrong name you will lose everything. With this command you can list the device on MacOS: diskutil list This is an example, my USB is the disk2: This command is to format the USB, the last parameter is the the USB: diskutil eraseDisk ExFAT 'WINDOWS10' MBRFormat disk2 Copy Windows files to USB - Method 1 This process is very easy doesn't require to install other software, and they are just a few steps: Open Windows ISO Just double click on the ISO image, MacOS mount the image automatically. Copy files Now you only need to copy the files and paste them to the USB. Command + A Select all files. Command + C Copy files.
Go to your USB Command + V paste the files. This process could fail if you are using a USB with FAT32 because the file install.win is over 4GB, if this is the case try to open the terminal and copy paste the files from there (no always works. Try to follow the instructions to format the USB in ExFAT, NTFS works for some BIOS). This is the command to copy the files from the ISO to the USB: cp -rp /Volumes/CCCOMAX64FREEN-USDV9/.
/Volumes/WINDOWS10/ And that is all, now you can try boot from the USB. UNetbootin - Method 2 I will show you how you can use to create a bootable USB, it can be used no only for Mac but for Windows and Linux distributions too. Is free software and it is also available for Windows and Linux.
Check the path name of your USB Disk. Always in Disk Utility, select the new partition that we created in the previous step, and click on the information button, it will give you the information about the new partition. You also can use the terminal and the command diskutil to see the list of drives: diskutil list Download UNetbootin:. Download the dmg directly from the.
And copy the app to the /Application folder. I prefer to use homebrew to install applications, you can check this article for more information:: brew cask install -appdir='/Applications' unetbootin Makes the USB booteable Open UNetbootin and you only need select 3 options:. Diskimage and ISO. Now we need open the ISO Windows image that is on our computer. Select your USB device on UNetbootin.
Click on the OK, button and wait to the process end it will take a time. NOTES:. I tested other tools like dd and Etcher but they are not working because Windows requires extra steps, for the moment this is the only easy tool that I know that works if you are on Windows try. Some users reported that UNetbootin is not working, if after to format the USB drive and change the block size is not working for you try another Drive with enough space. Share this post.
