CrashPlan: macOS Mojave not backing up files with personal data

Last Updated: May 1st, 2020/Published On: October 22nd, 2018/By /Views: 4874/


Apple introduced new privacy settings in macOS Mojave 10.14, which impacts the ability of RMTT Cloud Backup’s app, CrashPlan, to access some files from apps like Contacts, Photos, and Mail that contain personal data.

Due to Apple’s new privacy restrictions in macOS Mojave 10.14 for files and folders containing personal data, CrashPlan cannot back up some files from apps like Contacts, Photos, and Mail until you grant access to the CrashPlan app.
