Overview
This article describes a known issue which prevents you from accessing CrashPlan app log files on computers running Mac OS.
To correct this problem, follow the steps below to use the chmod
Terminal command to change the permissions of the CrashPlan app log directory.

macOS devices with the CrashPlan app installed for everyone. (Per-user installations are not affected.)

command. Learn more about enabling administrative access on OS X.
Diagnosing
Verify the problem by viewing the permissions on the CrashPlan app log directory:
- Go to Applications > Utilities.
- Open Terminal.app
The Terminal opens. - Enter this command:
cd /Library/Logs/CrashPLan
The Terminal attempts to open the CrashPlan app's log directory. - If the terminal reports
Permission
denied
, follow the recommended solution below.
For example:
prompt$ cd /Library/Logs/CrashPlan -bash: cd: /Library/Logs/CrashPlan: Permission denied
Recommended solution
Resolve the issue by changing permissions for the /Library/Logs/CrashPlan
directory:
- From the Finder, open Applications > Utilities > Terminal.
- Enter this command:
sudo chmod 755 /Library/Logs/CrashPlan
- Enter your password when prompted.
The password doesn't display as you enter it. - Verify that you have changed the directory's permissions by entering this command:
cd /Library/Logs/CrashPlan
- The Terminal opens the CrashPlan app's log directory.
- Enter this command:
pwd
The Terminal confirms that /Library/Logs/CrashPlan is open.
