i just thought I would write my experience with Windows 10 on Mac.
Having just purchased a new iMac I did not want to install Windows on it as I did on my old one (I had to hard drives one for Mac and one for Windows ) I do not like bootcamp or virtualisation.
Anyway back to topic as it is new I did not want to open it up to install extra drive so I did a bit of research on tinternet and decided to purchase a external SSD ( Samsung 500 gig SSD USB 3 ) installed Windows 10 on it using win2go connected it to iMac booted EFI before I had blinked it had booted up,
I then installed Apple for Windows drivers re booted but noticed the Magic Mouse only had left & right click,not what was used to so a bit more Google research and noticed it was a common problem but I found a bit of software magic mouse driver,installed that Magic Mouse back to normal.
The next problem was activation I thought I would have had a problem as I had upgraded to Windows 10 from Windows 8 on my old Mac but as my Windows 10 license was linked to my MS account I tried my Windows 8 product key and it activated.
it boots very fast and I am very pleased with the outcome, the only thing I have to do now is install my Mercedes wis asra workshop manual.
