Using balenaEttcher to create a macOS Tahoe bootable USB on Windows is possible, but with some important caveats:

Key Points:

• balenaEttcher can flash ISO or DMG images onto USB drives.
• It does not inherently make a bootable macOS installer; it simply writes the image to the USB.
• You need a properly prepared macOS Tahoe .iso or .dmg image that is bootable.
• Creating a bootable macOS installer from scratch on Windows is complicated because macOS images are not typically designed for Windows tools.

Step-by-Step Guide for Creating macOS Tahoe bootable USB on Windows:

1. Obtain a macOS Tahoe .iso or .dmg image
You need a bootable image of macOS Tahoe.
These images are typically created on a Mac, but you might find .iso images online (be cautious about their source and legality).

2. Prepare the USB drive
Insert a USB drive with at least 16GB capacity.
Backup any important data from the USB drive, as it will be erased.

3. Convert
If you have a dmg file, you may need to convert it to iso, as balenaEttcher prefers ISO files.

4. Flash the image with balenaEttcher
Launch balenaEttcher.
Select the macOS Tahoe ISO image file.
Select the USB drive.
Click Flash and wait for the process to complete.

5. Boot from the USB on your Mac
Insert the USB into your MacBook Pro M3.
Power it on and hold Option (Alt) key to select the boot device.
If the image is properly prepared and bootable, your Mac should recognize it and allow you to boot into the installer.

Creating a macOS Tahoe bootable USB on Windows involves some potential challenges and risks, but generally, it’s safe if you follow proper procedures. macOS is proprietary software licensed to Apple hardware. Creating macOS installers on non-Apple hardware may violate Apple's licensing terms. For personal use and experimentation, many consider it acceptable, but be aware of potential legal implications.

Downloading macOS images from unofficial sources can expose you to malware or tampered files. Always obtain macOS ISOs or installers from legitimate sources, such as the official Mac App Store or trusted repositories. Creating a bootable macOS on Windows generally requires third-party tools that might not be perfectly stable or compatible.

Even if you successfully create macOS Tahoe bootable USB on Windows, running macOS on non-Apple hardware (Hackintosh) can lead to driver or hardware compatibility issues. Some hardware components may not work properly without proper drivers or patches. Making bootable drives involves formatting and partitioning, which can lead to data loss if you're not careful.

Creating a bootable macOS USB can be a lifesaver when you need to perform a clean installation, reinstall the system, or troubleshoot a Mac that won’t start properly. In fact, the process involves more than just copying files to a USB drive as it requires correct formatting, a verified installer, and the right creation method to ensure it will boot successfully on your target Mac.

One important consideration is USB drive preparation. The drive should have enough capacity (at least 16 GB, but 32 GB is safer for newer macOS versions) and be formatted using GUID Partition Map with a macOS-compatible filesystem, such as Mac OS Extended (Journaled). Any existing data will be erased during the process, so it's essential to back up the USB beforehand. Also, using a high-quality and reasonably fast USB stick or SSD can drastically reduce the creation and installation time.

Another key point is to ensure you're using a genuine, unmodified macOS installer downloaded from the Mac App Store or Apple's official support site. Third-party or altered images may fail to boot, cause installation errors, or even contain malicious code.

These are very important tips you should take into consideration when you are planning to make a macos tahoe bootable usb from Windows PC. Let me know if you need more help on this.

Creating macOS Tahoe bootable USB on a Windows PC can be challenging because Apple officially provides macOS installers only through macOS. However, with some tools and workarounds, it is possible to create macOS Tahoe bootable usb on Windows.

Important Note:
macOS installers are typically distributed as .dmg or .app files, which are designed to run on macOS.
To create a bootable installer, you usually need a macOS environment or a way to run macOS (e.g., a Hackintosh, virtual machine, or access to a Mac).

Here's an overview of your options:
Option 1: Use a Mac or Virtual Machine

• The most straightforward and reliable method is to use a Mac or a macOS virtual machine to download and create the installer.    
• If you have access to a Mac, download macOS Tahoe from the App Store or Apple’s servers, then create the bootable USB.

Option 2: Download the macOS Tahoe installer on Windows

• You may find pre-built installer images (.dmg, .iso) from reputable sources or community forums. Be cautious with sources to avoid malware.
• Once you have the installer image, you can convert it to a bootable USB using tools available on Windows.

UltraDMG, the best app for creating macOS bootable USB installer on a PC.

Requirements

• A Windows PC.
• A USB flash drive 16 GB or larger (all data will be erased).
• The macOS 26 Tahoe installer image in .dmg format.
• The UltraDMG software.

How to make macOS Tahoe bootable USB from Windows PC

1. Plug in your USB drive.

2. In the main interface, click the Burn macOS and locate your USB under the Drive List.

3. Right-click the USB drive and select Format Disk for Mac.

4. Confirm formatting (this erases all data).

5. Right-click the USB drive again → choose Restore with Disk Image.

6. Browse and select your macOS Tahoe .dmg.

7. Click OK and confirm overwriting the USB.

8. Wait for the process to complete (can take 15–45 minutes depending on USB speed.)

UltraDMG is one of the easiest ways to create a macOS bootable USB on Windows 11 or Windows 10 PC. It works well if you already have the macOS .dmg file and need a Mac installer without access to another Mac.

Go and borrow a mac that is fully compatible with macOS 26 Tahoe. After that, use the built-in createinstallmedia command to create macOS Tahoe bootable USB.

Step 1: Open the App Store and search for macOS Tahoe. Click Get to download. The installer will appear in Applications as:

/Applications/Install macOS 26 Tahoe.app

Step 2: Apple provides a built-in tool inside the installer app to make the USB bootable. Open Terminal (Applications > Utilities > Terminal). Type the following command (adjust MyUSB to match your USB name):

sudo /Applications/Install\ macOS\ 26\ Tahoe.app/Contents/Resources/createinstallmedia --volume /Volumes/MyUSB

Step 3: Press Enter. Enter your Mac's administrator password (no characters will appear as you type) and press Enter.

Step 4: When prompted, type Y and press Enter to confirm erasing the drive. Wait for the process to finish. This can take 10–30 minutes depending on USB speed.

On a Mac, creating a macOS Tahoe bootable USB is best done using Apple's createinstallmedia command. It’s reliable, doesn't require third-party tools, and ensures full installer integrity.
