There are scanned PDFs available online.

However, my advice would be to actually purchase the book and then attain the audio .mp3s via an alternative online source.

Assimil does sell CDs - or directs you to their app - both are equally useless, at least that is my experience.

I tried creating an account as well.

No luck in doing so..

That is indeed odd. Perhaps the software is outdated, it may simply not be compatible anymore.

I hope you find a solution to your issue!

Note sure if Lab Tick has been mentioned, but it worked great on my broken MBP 2015 (MacOS Monterey)
