Mountain Duck

Mountain Duck is a cross-platform utility from David Kocher (Iterate GmbH) that “lets you mount any remote FTP, SFTP, WebDAV, S3 and OpenStack Swift server storage as a local disk in the Finder. Open remote files with any application and work like on a local volume. Transfer files using Finder to remote servers, fast.” Among many MountainDuck features is support for Cryptomator interoperable secure vaults (like cross-platform, cloud-friendly versions of Apple’s FileVault-encrypted Mac disk images).

Mountain Duck 3.3.6 is priced at $39 for OS X 10.11 and later with a trial version available for downloading (and also is available for Windows). The latest release has some bug fixes, after the previous release added support for TLS 1.3 networking and for Cryptomator Version 7 vaults. While Version 4.0.0 is in beta testing with some new features, Version 3 already added a smart synchronization feature for offline support:

Like Dropbox for any cloud storage with smart synchronization. Files are synchronized to your local disk when opened to allow offline usage and changes are uploaded in the background as soon as a connection is available. You can also explicitly select files and folders available for offline use.


iMazing is a cross-platform app from DigiDNA SARL for backing up, cloning and restoring all the data on iOS devices (including photos, music, videos, text messages, call history, voicemail, contacts, notes, voice memos, ringtones, etc.), transferring files between iOS devices and desktop computers (Mac and Windows), and managing music and other files. iMazing can be particularly helpful when you need to back up or clone an iPhone or iPad that iTunes refuses to back up when it’s tied to a different Mac that’s no longer available, or when there are compatibility problems among iTunes, iOS and OS X/macOS versions.

A rich set of features includes app management and download (after iTunes abandoned that), support for iOS device configuration profiles, a file/folder browser, drag-and-drop support, creation and renaming of folders, the ability to display and save detailed information about the phone (including battery info), bookmarks for files and folders, access to iCloud, HEIC file format conversion, “Time Machine-like backups of iOS devices via Wi-Fi”, compatibility with High Sierra (APFS), “a new backup archives format compatible with all kinds of portable storage, including NAS drives”, power-user features and more. (See iMazing FAQ for additional details.)

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 4.9.9 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 improves Google Cloud connections and disk image handling, along with minor bug fixes.

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.”

Other features include bookmark import/export among various browsers, plus browsing history. (See FAQ for additional details.)
