Wondering if anyone can help me out here, I'm looking for a genuine dmg file which I can use with transmac to create a bootable usb stick to install on a MacBook pro.
 
I needed to initialise the SSD via ubuntu command line first, didn't show up at all in the installer (Yes, i clicked view > all devices).

Macs just frustrate me!
 
I thought that disk utilities was available in the installer. But if not you could use fdisk or diskutil. fdisk is probably simpler.
 
I've had a few Mac SSD upgrades where the new SSD wasn't visible to the OS installer. Worked around it different ways as I recall. One I think I restarted in Target Disk Mode and attached it to another Mac to initialize the disk. On another I think I removed the SSD and initialized it on a different machine with a USB adapter.

So you had a similar issue and booted Ubuntu installer to initialize the SSD then boot the macOS installer to install the OS?
 
We've never had an issue with brand new SSDs with High Sierra, as long as you remember to follow what I said.
In the installer open the Disk Utility then go to View and select Show All Devices, then close Disk Utility and open it again and the drive is there.

Correct, exactly!
