Best way to burn iso to usb on Mac? I need a Windows 11 bootable USB

I understand your situation, and I can guide you through creating a bootable Windows 11 USB installer using your MacBook Air M4. Since Boot Camp Assistant is discontinued, you can use alternative methods to burn ISO to USB on Mac.

Here's a step-by-step guide to Burn ISO to USB on Mac:
1. Download the Windows 11 ISO. Select the edition and language, then download the ISO file: Insert your USB drive into your Mac.
2. Format the USB drive:
    Open Disk Utility (Applications > Utilities > Disk Utility).
    Select your USB drive from the list.
    Click Erase.
    Choose MS-DOS (FAT) or ExFAT as the format.
    Set the scheme to GUID Partition Map.
    Click Erase.
3. Use Terminal to create a bootable Windows installer:
    Open Terminal (Applications > Utilities > Terminal).
    First, identify your USB drive: diskutil list
    Find your USB drive (e.g., /dev/disk2).
4. Unmount the drive:
    diskutil unmountDisk /dev/diskX
    Replace diskX with your drive's identifier.
5. Write the ISO to the USB:
    sudo dd if=/path/to/Windows11.iso of=/dev/rdiskX bs=4m status=progress

The dd command can overwrite any drive without warning, so double-check the drive identifier!
