#Create mac bootable usb from windows without transmac for mac#
The process involves first formatting the key for Mac and then dump an image of OS X to the key. With another key, I used the commonly described process with TransMac. During that process, the drive went read-only and never returned. First I needed to find something big enough. Then there’s the process of preparing a USB key on Windows. I would not expect this to work for you either, but, without the recovery partition, every boot-up ends up at this failing process. This process seems more like a hail Mary and no matter what kind of connection I provided (direct Ethernet, WiFI) it failed.
I did that by holding down Command + Option + R which is great, the spinning globe started. Here’s a look at recovery options, what failed at every turn and what finally got me there.įirst, they say to boot into Internet Recovery. But, those steps also kill your recovery options too. I think this happens most often when we try to re-use a Mac and follow the steps (which include erasing the drive). The process of reinstalling OS X on a Mac when you have only Windows computers around (and no recovery partition) is very specific, yes, but it’s happened to me a few times. But, I can off you hope that it is possible and you can get your Mac running again. Every other step you’re going to take will lead you to failure.
You could do this faster on another Mac (but I know you don’t have one of those). Or, more specifically OS X running in a virtual machine on a Windows computer. I’ll just cut to the chase: You need a Mac.
