如何在Mac中安装damaged的dmg文件 博客分类： Mac macinstalldmgdamagedcan not open

 

 when installing code collaborator client in my Mac, i meet the following error massage.

 

 "Code Collaborator Installer" is damaged and can not be opened.you should eject the disk image.

 

  i tried many times and got the same error massage. don't know why. then a workmate from US tell me how to resolve this issue. here is the steps.

 

(1) delete the quarantine attribute on the downloaded installer.  Run this command to do so:

 

xattr -d com.apple.quarantine ccollab_client_8_4_8406_macos.dmg

 

(2) install it again by double click the dmg file.
