Here is a nice tutorial for creating bootable USB on Mac: Also, this app works on latest Big Sur and M1 Mac as just tested it on a M1 MacBook Air with macOS Big Sur 11.5. It automatically splits the large ISO file into small parts so the Windows installation files can be sit on a FAT32 partition, which is the only working file system supported by Mac for Windows install.
If you are using a newer Windows 10 ISO (after version 201809), then UUByte ISO Editor is the best app for creating a bootable USB on Mac. I managed to create several bootable Windows 10 USBs on Mac (Mojave, Catalina and Big Sur) in recent years. I had to create a Windows partition on my hard drive and boot into that to make a functioning boot drive. The ExFAT formatted drive with Windows ISO did not work as a bootable drive.
Will report back if I run into any issues.
All this said, I have yet to actually use this drive to INSTALL Windows as I'm building the computer tomorrow. I just did this with a Sandisk 32GB drive and it worked perfectly. Select "ExFAT" in the format dropdown and confirmĪfter this process you are able to move larger files into your USB drive. Select drive you want to be the boot drive Here are the steps! For reference I'm running Mac OS Monterey (v12.0.1)
The easiest thing to do is just to reformat your drive to 'ExFat' using Disk Utility. Sorry if this is a breach of etiquette (commenting on an old thread!)
You don't need to download any new software to do this, everything is already included in current Mac OS. If this tool helps you, give him a thumbs up somehow - he deserves it, and hasn't been noticed for all these years.In case anyone stumbles onto this thread I'm going to give what I believe to be the easiest solution to this problem.
There's even a downloadable PDF within the tool, with instructions on how to finish the job (install macOS using the recovery). Give it a try and see for yourselves - its amazing - it grabs the images from official apple cdn servers. it downloads the recovery and flashes it onto the second partitionĪll of this done in 15mins max (unlike TransMac which one time took over 15 hours) then gives you a list of the latest macOS recovery images to choose from - you choose the one you want (approx 500mb) partitions your usb into 2 partitions, one of which it flashes the bootloader onto (approx 200mb) - and the other left empty converts and partitions your USB to the correct mac required format downloads the latest, Clover bootloader revision, Make bootable USB Flash Disk for macOS with Latest Clover bootloader revisionĭownload(with resuming) Latest!

It turns out a dev going by the name of ' cvad' from Russia, created the tool we've all been looking for (before Windows XP time!). List of threads that have non-working solutions:
Multiple failed attempts later, and multiple attempts with different images, and a different USB - i came to the conclusion that TransMac is rubbish Tried TransMac multiple times (and it takes over 10 hours to burn the image). Many hours later, ive downloaded multiple macOS images from multiple sources. (this is was my research led me to believe). Everyone who failed, failed because they didn't do the 'DiskPart' first. The next part was to use "TransMac" - the "only tool for Windows" that could burn the mac image. The trick involves using Windows Disk Part - 'select disk' - 'convert gpt' - etc etc So off i went to my special Rufus tool, which turns out does not work for mac images.Īfter many hours, i found the special trick posted on multiple sites. Soon enough i realized i could no longer boot into recovery.
I messed up an old iMac trying to update it to Catalina (formatted the recovery drive, lol - first time playing with a MAC).
