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.
