I just downloaded Calibre on my Macbook (currently MacOS Tahoe 26.6.2). I moved the Calibre .dmg file into the Applications folder, but the error message (i.e. "The disk image couldn’t be opened. The operation couldn’t be completed. Input/output error”) persisted.

What should I do so that I can open and use Calibre properly on my Macbook?

The version I downloaded was the latest one as of now, that is, Version: 9.13.0.

Any advice and/or input would be very much appreciated. Thank you in advance!
