ChronoSync is a Mac app from Econ Technologies, Inc. that can synchronize and backup to almost any storage connected to a Mac, including local files (folder to folder sync), other Macs or PCs, external drives, and cloud services. You can schedule tasks, customize rules/filters, define scripts that can run multiple syncs simultaneously, automatically archive deleted or replaced files, use NFS file servers and more.

ChronoSync 4.9.10 is priced at $49.99 for OS X 10.11 and up with a 15-day trial available. (Older versions are available for earlier Macs.) The latest release has workarounds for unexpected problems Apple created in macOS 10.15.5.

TNCS-0047 – ChronoSync Bootable Backup on macOS 10.15.5 Catalina
Apple’s release of macOS 10.15.5 has broken the capability to create new Bootable Backups using ChronoSync v.4.9.9 and earlier. Whether it’s a macOS bug or a feature we have released ChronoSync 4.9.10 that implements a work-around to restore the creation of new Bootable Backups. The widely-publicized issues in macOS 10.15.5 that prevent the creation of Bootable Backups prompted this maintenance release.

ChronoAgent 1.9.7, priced starting at $14.99 per license, “is an invisible application that runs silently in the background on a Mac and provides ChronoSync or InterConneX a direct connection to a remote Mac”, protected by a login and optional encryption. ChronoSync can be used as a backup server, pushing or pulling data as required.

InterConneX 2.0.1 is a free file management app for iOS 9 and later that can consolidate mobile files in a “sharespace” container and synchronize files with Macs running ChronoSync. Version 2.0 improved robustness (in conjuction with a ChronoSync update) and brought a new “adaptive interface which allows multitasking and support for drag and drop.”

ChronoMonitor 1.1.4 is a $3.99 app for iOS 8 and up “that monitors Macs running ChronoSync or ChronoAgent.”

VMware security update

VMware Fusion 11.5.5 patches a security problem in the cross-platform virtualization system from VMware Inc.

Attackers with normal user privileges can exploit this issue to escalate their privileges to root on a system where Fusion is installed. The Common Vulnerabilities and Exposures project has assigned the identifier CVE-2020-3957 to this issue. See VMSA-2020-0011 for more information.
