That's a major pain to use when downloading a big batch after a spending spree. It also uses low quality images in comics. The Kindle for desktop apps download the highest quality images available (albeit a bit of pain to combine with separate azw3+azw6 files).

Got my M1 Mac mini (16GB Ram, 1TB SSD) Nov 25 and Calibre works fine. I haven't found anything that doesn't work properly. Performance is fine--maybe just slightly better than my 2018 Mac mini with core-i7, 512GB SSD and 64GB ram.

For benchmarking, I converted Follett's Fall of Giants to kfx and compared the performance to that of the 2018 Mac mini:

kfx conversion 2018 Mac mini: 107 seconds
kfx conversion 2020 M1 Mac mini: 100 seconds

I use a number of plugins, not problems. I also have my own Python programs that access the calibre database remotely to grab information using calibredb and it all works perfectly.

Given the massive change to the hardware on the M1 devices, Apple has been very successful making almost everything compatible without compromising performance.

The main thing I would suspect of having issues is the Viewer or the preview panel in the editor, as they use a web browser under the hood, which in turn uses a Just in Time compiler for javascript, these tend to be the hardest things to run via emulation.

I got my M1 Mac today. No problems with viewer, no problems with preview panel. It works extremely fast and perfectly. I am very pleased. Every Intel app I have tried has performed flawlessly so far. I haven't tried Alf's tool (I am assuming it won't work) but assuming one has a backup computer for that, everything is peachy!

That's good to know, thanks

I have posted on the Github (#1369) and in a couple of other threads here, but am having no luck with a solution.

A solution could be Crossover 20.

Installation of Calibre 3.48 (32-bit) is working on my Intel MacBook. I guess this will also work on M1 Mac. Then install DeDRM_tools_6.8.1 in plugins and try if it's working.

I have ordered a MacBook Air M1...but will arrive in January 2021. So, I cannot test yet.

I've got a shiny new M1 Macbook Air (8GB, 512GB) and Calibre 4.23 works great. But I'm not able to convert. Books downloaded with the latest Kindle for Mac app don't really even load into Calibre...they just come in as "ebok" files (so maybe I'm doing something wrong there?). Books downloaded for "download and USB" transfer load into Calibre just fine, but don't convert...once again, I think I'm doing something wrong, but I'm not sure what. Something to do with my Kindle key, I'm sure.

I'm coming from Windows, where this all worked pretty well. Still got my Windows machine, but not for much longer (I hope).

Have you configured K4Mac not to download KFX format? Did you enter your eInk Kindle serial number into the right spot in the DeDRM plugin configuration? You might want to check the Dealing with Kindle for PC/Mac 1.19 and KFX in calibre thread in the stickies.

Good luck!

Meanwhile I have my MacBook Air with M1-processor. Everything is working fine. Also Alf's DRM plugin is working. I didn't find anything not working.

Which version of Calibre?

Latest version.

jmmcg9 · 01-21-2021, 12:12 PM

All, I am now successfully using the latest version of Calibre on my M1 MacBook Pro (16M Ram). I initially had issues getting Alf’s plug-in to work. The problem is that Safari unzips the download automatically. I had to download the plug-in file on my Windows PC, then copy on to a flash drive. You have to add the unzipped version of the file for it to load properly.
Sweet!
Joe

Using a proper browser like Firefox or Chrome might also have worked

jmmcg9 · 01-22-2021, 07:39 AM

Yeah I use Chrome on my work PC. That would have been my next option. As far as being a “proper” browser, using both, in the Mac OS environment, my preference is Safari.
