Convert ICBU to VCAL

Understanding the ICBU and VCAL file formats

ICBU files are backup files created by Apple’s Calendar application (formerly iCal) on macOS. These files store calendar data, including events, reminders, and associated metadata, in a proprietary format used for restoring or transferring calendar information between Apple devices.

VCAL (vCalendar) files, with the .vcs extension, are a standardized format for exchanging calendar and scheduling information. VCAL files are widely supported by various calendar applications, making them ideal for sharing events across different platforms.

Why convert ICBU to VCAL?

Converting an ICBU file to VCAL format allows you to transfer your Apple Calendar data to other calendar applications that do not support the ICBU format. This is especially useful for users migrating from macOS to other operating systems or sharing calendar data with non-Apple users.

How to convert ICBU to VCAL

There is no direct one-step converter for ICBU to VCAL, but you can achieve the conversion through a two-step process:

1. Restore the ICBU file in Apple Calendar:
   • Open Calendar on your Mac.
   • Go to File → Import and select your .icbu backup file.
   • The calendar data will be restored to your Apple Calendar.
2. Export the calendar as VCAL:
   • In Apple Calendar, select the calendar you want to export.
   • Go to File → Export → Export…
   • Choose the .vcs (vCalendar) format if available, or export as .ics (iCalendar), which is more common and widely supported.
   • If only .ics is available, you can use an online converter to change .ics to .vcs.

Recommended software for conversion
