UPDATED: Dupin v3.0.3
I'm happy to announce an update to Dupin, the duplicate tracks manager (and disposer-of also). Dupin v3.0.3 fixes a stinky bug with Re-Playlist process that prevented it from proceeding properly under some circumstances.
More information, updating and system considerations, FAQ and download are accessible from this page.
Dupin v3.0 for macOS 10.15
I've bumped Dupin up to version 3.0. It is for macOS 10.15 and later only.
Dupin eliminates the drudgery associated with managing those irksome duplicated tracks in your Music library.
You won't be able to update to the new version of Dupin via Sparkle from the last version, v2.14.1, because that version can't run on macOS 10.15. So you'll have to get Dupin v3.0 right here on the website.
Dupin v3.0 is a free update for properly registered users and requires macOS 10.15 and the new Music app. A new registration code is US$15 and registrations older than five years can be upgraded for US$5. Download and try it free in Demo Mode. If you're staying away from Catalina for a while, Dupin v2.14.1 is still available to work with iTunes.
Dupin Lite 2 v1.4.0 Now at Mac App Store
Dupin Lite 2 has been updated to version 1.4.0 and is now available on the Mac App Store.
Dupin Lite 2 is a "lighter" version of my iTunes duplicates-managing app Dupin. It has fewer power-user features and essentially gets right to the business: find dupes, filter for Keepers, Purge.
This latest version accommodates Dark Mode under Mojave and adds some performance enhancements.
Dupin v2.14
I'm happy to announce the release of Dupin v2.14, which adds a couple of navigation features I found myself wanting.
In case you don't know, Dupin works with iTunes to discover, manage and even remove duplicate tracks and files. But Dupin allows you a way to establish exactly what properties of tracks make them duplicates and to choose which single track of a "Dupe Group" of tracks is the "Keeper" and which are the "non-Keeper(s)". The latter Filtering can be done automatically or manually by scrolling through the Dupe Groups.
Dupin is available to try in Demo Mode, whereby some features are limited. A registration code to unlock the Demo Mode is $15.00.
Dupin turns eleven years old this year and wouldn't have stayed alive so long without such a great group of users. So thanks!
UPDATED: Dupin v2.12.2
There was a bug with Dupin running under High Sierra that distorted the buttons in a Purge dialog and made them somewhat un-responsive. I hadn't seen this in the 10.13 betas so I wasn't expecting any issues when the final release of 10.13 came out this week.
Luckily, an alert Correspondent let me know about it and I fixed it right up this morning. Current users can "Check For Update..." in Dupin's application menu or download the latest version on this page.
I've also submitted an update for Dupin Lite 2 and that should be up on the App Store in a day or so.
UPDATED: Dupin v2.12.0
I've posted Dupin v2.12.0 which has initial accommodations for macOS 10.13 High Sierra.
Dupin is the iTunes Duplicates Manager.
In addition to the macOS 10.13 considerations and obligatory performance enhancements, I've added a "Reset to All Keepers" button to the Filter Controls. I don't know what took so long on that. There is also a new "Local files" option added to the "Always Keep this Kind" popup.
The View menu now allows you to select to view only Dupe Groups that contain dead or cloud or local file tracks.
The Library Profile utility in the Help menu has also received some improvements.
Dupin v2.12.0 is free to try in Demo Mode during which it will only operate on twenty Dupe Groups at a time with one "Purge" operation allowed per launch for up to eight launches. A registration code to remove the Demo Mode restrictions is $15.00. This update is free if you purchased your current registration code within the last five years. Out-of-date registrations can be updated for $5.00 by downloading and launching the latest version and making an in-app purchase.
More information, links to the FAQ page, quick-start video and download is available from this page. Current users can hit "Check for Update..." in Dupin's menu.
UPDATED: Dupin v2.10.2
I've posted a minor maintenance update to Dupin, the iTunes duplicates manager. I had to fix a minor incompatibility issue with how OS X 10.11 displays a Quick Look window.
Did you know that Dupin even used Quick Look? You can select a track in Dupin's track list, press Space Bar, and a Quick Look panel will display whereby the track can be played:
Comes in handy when you need to audition the tracks without having to locate them in iTunes first.
Dupin ($15.00) has many other features that will help you manage (and perhaps eventually Trash) your iTunes duplicates, like flexible dupe filtering, Re-Playlisting, "dead" track removal, and more. And it's compatible with iCloud Music Library tracks. This latest version (v2.10.2) is a free update for registered users.
Dupin v2.9
With Dupin you can:
- Very quickly find all sets of duplicate iTunes tracks based on your choice of criteria
- Select the "Keeper" tracks from among a number of duplicates automatically using a variety of versatile filtering options
- Consolidate the play, skip, and ratings information from all tracks in a Dupe Group to the single "Keeper" track
- Re-populate iTunes playlists replacing "non-Keeper" tracks with "Keeper" tracks
- Remove duplicate tracks from iTunes and send files to the Trash

- Manage intentionally duplicated tracks
- Delete duplicate "dead" tracks

In addition, Dupin features:

This latest version is a maintenance release with performance enhancements and is a free update for registered users.

I fixed a couple of bugs that occur with iTunes 12.2, mostly cosmetic. Click "Check for Update..." in your current version or download the lateset from here.
Similar bugs showed up in Dupin Lite 2 and a new version has been submitted to the Mac App Store for review. It should be available from there in a few days.
Dupin v2.8.6 Released
Dupin v2.8.6 is now available. This is a maintenance update that includes some minor performance enhancements, a fix for potentially slow progress indicator animation under Yosemite, and preliminary support for the OS X 10.11 beta.
