It doesn’t matter whether you use wether windows pc or Mac. The problem came due to many reasons that can malfunction your device, and a working device crashes or slows down with time, and you need to rerun its installation from the start. This could happen due to a bug in your device, any update in the system, or anything else which can affect your system. Sometimes we don’t have Mac to create a bootable USB for our Mac, so we can make our bootable USB to boot our Mac from a windows pc
Now you should run the installation of your Mac by creating your bootable usb in any of the mac devices ((MacBook, MacBook Air, MacBook Pro, iMac, Mac Pro, or Mac Mini), but if none of your devices is currently working, then there is only one way to secure your device and data by creating a bootable USB from any of your Windows PC. This way, you can install macOS Ventura, Monterey, Big Sur, or Catalina on your Mac.
Below is the complete guide to creating a Bootable USB for Mac using your windows pc.
What we need
To make a USB bootable for Mac, we need the following things;
- Mac computer running macOS.
- TransMac software.
- One high-quality USB flash drive with 16GB of storage.
- Copy of macOS (DMG file).
Create MacOS bootable USB
Here we will guide you step by step to demonstrate how to create a MacOS bootable USB using your windows pc.
Download and install TransMAC.
It is a paid software, but we will use it for free in this tutorial as it provides 15 days of the free trial, which is enough for us to make our USB bootable.
Connect the USB flash drive, and don’t forget to save the data stored in your USB as this process will all data from your USB, so it is better to make a backup or keep it.
Now run the TransMAC as administrator.
Click on the run button and wait 15 seconds, as we use the free trial version in this demo.
Right-click on the USB we have already inserted and click the option “Format Disk for Mac” in the left panel.
Click yes to grant permission to format your device.
Create the name of the drive that you want. For instance, “macOS bootable USB.”
And click the ok button to continue.
Then click yes and continue.
Now right-click again on the USB and select “Restore with Disk Image.”
Now confirm erasing your disk by clicking the yes option.
Browse and select the DMG file you have already downloaded for macOS installation.
Click open and Ok; at the end, press yes to start the process.
Once you have completed the steps and the process ends without error, your USB will be bootable, and you can insert it into your Mac. You can install or upgrade to the latest version of Mac (Ventura, Monterey, Big Sur, Catalina, or Sierra).
Change the partition type of your USB
If the above process doesn’t work, then you don’t need to worry about it; change the partition type of your USB from MBR(Master Boot Record) to GPT(GUID Partition Table) and again rerun the above process.
Below is the complete guide to creating a GPT partition in your USB.
- Click the Windows logo.
- Search for Command Prompt, right-click the top result, and select the Run as an administrator option.
- Type the following command and press Enter: “diskpart”
- Type the next order to view all drives connected to your computer and press Enter: “list disk“
- Type the following command with the number assigned for the USB flash drive and press Enter: select disk 4In the command, change “4” to the number corresponding to the USB flash drive.
- Type the following command to clean the drive and press Enter: “Type the following command to convert the drive to the GPT style and press Enter: convert gpt
- Type the following command to create a primary partition and press Enter: create partition primary.
Once you have formatted the USB flash drive with a GPT partition, you can use the instructions mentioned above to use TransMac to create a bootable media, but this time skip steps 5 through 10 and continue on step 11.
After the process is complete, which it’s something that could take up to an hour, connect the USB flash drive and power on your Mac by holding down the Option key, and select the USB drive to begin installing macOS.
