CalendarFree
CalendarFree is a productivity application developed by Qbix that provides calendar management functionality for Mac users. The app was designed to offer an alternative to the built-in macOS Calendar application, with features for organizing schedules, events, and appointments. However, CalendarFree gained notoriety in 2018 when it was discovered to contain hidden cryptocurrency mining software, leading to its removal from the Mac App Store by Apple. The app was found to secretly run mining operations in the background while appearing to function as a legitimate calendar application, making it a security concern for users.
Suggested Replacements
1 suggestionDue to serious security concerns, CalendarFree should not be used or installed. The app was removed from the Mac App Store in 2018 after being discovered to contain hidden cryptocurrency mining malware that would secretly consume system resources. Instead, consider using Apple's built-in Calendar app, which has excellent Apple Silicon support and integrates seamlessly with iCloud, or alternatively, Itsycal, a lightweight menu bar calendar that supports macOS 11+ including Apple Silicon Macs. Both options provide legitimate calendar functionality without security risks.
