Q: DMG File Extraction Error

My system is Yosemite.I wasn't aware of this problem occurring until my Mac failed updating.Then I found out that I cannot copy anything out of a dmg file.This prevents me from updating the system and every time I want to close my computer I need to hold the power button to shut it down(or it cannot close up to 10 hours and the fan begin to run).How could I fix it?

MacBook Pro, Mac OS X (10.4)

    For the DMG file, what happens if you control - click on it and select open?
