Hello guys,

I am pretty much new to the community. I managed to install High Sierra on my pc today.
Here are my specs:

CPU: intel i7 6700k
RAM: 16GB DDR4
Graphics: Palit GTX 1080
Motherboard: MSI B150 M3

I managed to get ethernet, sound and graphics working, but after downloading any external .dmg file from the internet and trying to "unpack" it, the DiskImageSays:

Image data corrupted

I think it has something to do with bootloader? Maybe I did something wrong?


Thanks for the help in advance!

Edit1: I have managed to download Telegram and Chrome dmgs and installed them without a problem, but after I tried downloading IntelliJ and Discord and both dmgs are corrupted.
 
Change your System Preferences - Security & Privacy - General settings to Allow apps downloaded from App store and identified developers (or Anywhere).
 
Okay so I removed everything form the Download directory and now it seems to be working.
