„Install CrashPlanPROe” can't be opened…
Since Mountain Lion 10.8, the Mac defaults to preventing applications from unidentified sources from being launched. You’ll get an alert dialog that says:
“"Install CrashPlanPROe" can’t be opened because it is from an unidentified developer. Your security preferences allow installation of only apps from the Mac App Store and identified developers.”
Unsigned
The CrashPlanPRO installer that you downloaded from crashplan.probackup.nl is not digitally signed with an Apple-approved signature. Therefore it will only install without warnings when Gatekeeper is set to "Allow applications downloaded from: Anywhere".
Solution: right click
Despite the Gatekeeper setting, you can still install CrashPlanPRO by following these steps:
- In Finder, press the Control key, and then click the "Install CrashPlanPRO" app icon
or
Right click the icon of the "Install CrashPlanPRO" app icon.
- Choose Open from the shortcut menu.
- You'll still get a warning, but you'll also get the choice to Open the program anyway.
- If you're not logged in as an administrator, you'll be prompted to authenticate as one.
