I have an older Mac and the download file/bottle is empty when I try to download the Installation Media. I don't know if this affects anything but the options for windows only stop at Windows 10.
What apps is that even?
MS is giving you a download from their page
Go to the 'Download Windows 11 Disk Image (ISO) for x64 devices' section and click on download.
If you need a special version for macs or something then it's not a windows related issue and you should ask somewhere with plenty of mac users that would be able to help you. https://www.microsoft.com/software-download/windows11
