Manually creating the appropriate partitions to create a macOS bootable USB for Sequoia using Windows' native Disk Management tool may sound simple, but it's actually quite complicated, especially without third-party tools. Here are the specific steps and key points:

Steps:

1. Insert the USB drive: First, insert your USB drive into your Windows 10 computer.
2. Open the Disk Management tool: Press Win + X and select "Disk Management".
3. Select the USB drive: Find your USB drive and make sure there is no important data on it, as it will be formatted next.
4. Delete partitions: Right-click the current partition of the USB drive and select "Delete Volume" to clear all existing partitions.
5. Create a new partition: Right-click the unallocated space, select "New Simple Volume", and then select the partition size you want. Although there is no option to directly format as Mac OS Extended (Journaled) on Windows, you can choose FAT32, which is compatible in some cases.
6. Manually copy macOS files: After formatting is complete, manually copy the downloaded macOS Sequoia installation file (DMG or ISO) to the USB drive.

Windows Subsystem for Linux: This feature allows you to run a Linux-based environment directly on your Windows machine, which can be useful for creating a bootable macOS USB drive.

Note: Use a high-quality USB drive with a high capacity (at least 16GB) to minimize errors.
