With Mojava I used the same 16 GB USB stick (Kingston DataTraveler, USB 2.0) and the same Windows 10 ISO (Win10_1803_English_x64.iso) several times before to create a bootable drive to install Windows. Now, all of a sudden, Boot Camp Assistant states: "Your bootable USB drive could not be created - There is not enough space available on the disk". I tried partitioning it as APFS, Mac OS Extended (Journaled), MS-DOS (FAT) and ExFAT before starting Boot Camp Assistant. Apple's "help" articles didn't help me, either: https://support.apple.com/hr-hr/HT206202 https://support.apple.com/en-us/HT201468 The USB flash drive seems to be fully functional and Disk Utility's First Aid found no errors. Why does it suddenly not work anymore?
