Econ Technologies today announced the availability of ChronoSync 3.3.3, the latest version of the automated synchronization and backup application for Mac OS X. This maintenance release fixes a few bugs discovered since the release of Mac OS 10.4.8. ChronoSync will run natively on both Power PC- and Intel-based Macs running Panther or Tiger. The company says this update is “a must-have update for all users.” This maintenance release fixes a problem introduced under Mac OS 10.4.8 which leads to permissions errors on locked files. Fixed a bug that could cause a file copy failure if: there was no opposing file, the filename length was greater than 30 characters and the filename began with a “0”. Finally, corrected a problem whereby rollback pre-determination could not be specified for mirrored sync modes. ChronoSync is priced at US$30.
