iATKOS | United Kingdom

I don't have a mac, nor a hackingtosh (yet), and neither does anyone in my family. I was thinking of going to an apple store and doing it, but there is no apple store near me. I tried some downloads i found on the internet, but when i used transmac to recover the disk from the image it just made it unallocated so i was not able to mount it to put clover on. Can someone here do me a favour and send me a working .dmg of high sierra?
