Can't remove AZW DRM with DeDRM

[rcmit]

Using DeDRM 10.0.3 with Calibre 6.1 on MacBook Air with M1 processor running MAC OS Venture 13.3.1. Have 3 different Kindle Oasis serial numbers configured because I wasn't certain if some symbols were "O" or zero. Downloaded several books to Mac. All received error that file contains DRM with I attempt to export to ePUB.

You need to use the Download & Transfer function of Amazon's website targeting your e-ink Kindle device to download the book. The same book downloaded using the Kindle for Mac app has a different format with different DRM.

Thanks for the super fast response! Robert

Another tip: copy and paste your Kindle serial number from the website and you won't have to worry about 0/O or 8/B etc.

so that means this thing cannot be used if you dont have a kindle in the first place but are software only so far?

[ElleKayEm]

No, you don't have to have a Kindle.

[My1]

okay? then how to actually do it then? because I applied the plugin and the Kindle for windows azw download doesnt open and the replies above mention download & transfer or a kindle serial number, which seems to imply that a kindle is needed.

That was in response to someone who had a Kindle. See this post: https://www.mobileread.com/forums/showthread.php?t=283371
