Mac: Disk not recognized

I got UDK4 for mac, .dmg file,
it shows a warning
" disk not recognized "
and I can’t install it.
I have met the requirements, why is it?

I’ve installed ue4 on my iMac yesterday without any problems
Try downloading it again

thanks but,

I have downloaded it several times, but no works

Don’t know what worked, I solved! yeah

  1. 1 of re-downloaded files (only 1 works in 7 files)
  2. installing Mono project
  3. several times of restarting
  4. some setting at system preferences

Thank you for replying

I am glad that you solved the problem with install :slight_smile:
How is ue4 performance on your mac?
