Hi! I want to tell a problem. Two weeks ago i Installed High Sierra. I've version 10.12.6 and today after two weeks my mac can't read file .dmg. It doesn't report any error, just doesn't open it. Any ideas?

A .dmg file is a compressed file similar to a .zip allowing a quick download of an installer. Have you checked your desktop for what appears to be an icon of a drive or DVD? Check your download folder where the .dmg is located.

Is this .dmg from a download from a trusted site? It could very well be corrupt or empty (no files in it).

You can try using Disk Utility to force open the .dmg. If there is a problem with that file, it will tell you.
