Which version of tools for OSX 10.13 ?

[larfran]

Hi, I have an old Mac, with OSX 10.13.
The version of Calibre is 3.48.
Wich version of DeDRM I should use for it ?
Thanks!

Edit: Ok, 6.8.0 is ok. Don't forget to unzip it and download from calibre app the files.zip into. That was my fault.

The latest 10.0.9 is meant to be backward compatible too. But as you say, 6.8.x definitely works as long as you're dealing with older DRM types.
