Launched TeamViewer and it's working like a champ. Sudo installer - pkg / path / to / package. You should eject the disk image.' Mounted the DMG through Terminal then ran I launched the Installer and got “Install TeamViewer” is damaged and can’t be opened. I used terminal again to mount a DMG (TeamViewer) that I needed to install and that I know works on my other notebook running Sierra. The OS went through the verification process, something it had not done before, then came back with the message above. I ejected the DMG then tried to open it normally. Went to terminal, typed hdiutil attach followed by the path to DMG ( /Users/me/Downloads/iTunes12.7.dmg ) and it mounted. Can't seem to change that setting either. Went back to the Security & Privacy pane and found that 'App Store' only was checked. To add to it, I went to Security & Privacy, set Allow apps downloaded from: App Store and identified developers, closed System Preferences, and tried again.

Safari downloaded this file today at 6:52 PM from This particular DMG was downloaded from Apple after I had done my migration. While I have not checked all of my Apps, everything I spot checked works fine with one exception, I can not open any DMG regardless of who it is from.įor example “iTunes12.7.dmg” is damaged and can’t be opened. Got no errors or issues during the transfer. I just did a bare a metal install of High Sierra on my 2012 MBP, did the updates and then migrated my 2011 MBP with Migration Assistant.
