OK, I have a MacBook Pro, 9,1, mid-2012. Current OS is Mojave, 10.14.6 + security updates. I have a recent .winclone image of my Windows 10 (Home) installation. So I can recover. But I was hoping to try a clean install of Windows 1909 using Boot Camp Assistant. I have tried both the .iso that Apple recommends and an Enterprise iso I got using the MS Media Creation tool using Windows.
Boot Camp assistant accepts the Apple recommended download, but shouts that there is “not enough space” on a 32 GB ExFAT USB2 drive. If I use the TwoCanoes tool for subdividing the .wim file, it says it needs a “64-bit version of Windows 10”, and fails. It gives an identical error for the Enterprise iso.
I have tried resetting SMC and nvRAM. I have verified the md5 of the Apple approved iso against what it’s supposed to be. I’ve tried creating the USB manually - dragging files and folders, and that allows installing Windows 10 - but only in EFI Boot mode, and my 2012 machine isn’t fully supported - specifically, audio drivers don’t work.
Is there anything that I can do as a workaround using Winclone? I saw a knowledge base article on using Winclone to create a .winclone file from a Windows .WIM installer. But would doing so get me any closer to being able to install Windows 10 on my 2012 MacBook Pro?
Thanks for looking.
