Should you need to remove DRM from a rented library book for a bit past your due date, the following should help.
- Download the current version of DeDRM from Alf (
6.5.5, 6.6.1, 6.6.3, or newer — see UPDATE 3, below).
- Unzip the downloaded DeDRM tools file
- Open the application at the following location DeDRM_tools_6.5.5->DeDRM_Macintosh_Application->DeDRM.
- Click “Select Ebook…”
- Now open a browser and rent a book from your public library.
- When it is available, download the book – I typically go for the ePub, which is viewable in iBooks or Adobe Digital Editions 2.0 or newer on a Mac.
- A file with a .acsm might be downloaded from the library, double-click this file to open it in Adobe Digital Editions 2.0 or newer.
- Inside ADE, an ePub of your book will be downloaded from the library and it will expire in a set number of days. Right click the book inside ADE’s library and select “Show File in Finder”.
- When this book is shown in the Finder, drag it to DeDRM’s file select window (Step 4) titled “Please select a DRMed ebook” and then click “Choose”.
Success. A copy of your rented book will be stripped of its DRM and saved in the same directory as Step 4.
** UPDATE #1 ** 6.5.5 and 6.6.1 are not launching on macOS 10.13.6. Will look further into this.
** UPDATE #2 ** I never looked further into the above situation, but 6.6.3 is working fine for me on macOS 10.13.6.
** UPDATE #3 ** Catalina breaks compatibility. Calibre is the workaround. Haven’t tried this myself, but download Calibre and then run DeDRM as a plugin.
