macos 10.13.6 High Sierra I have no antivirus software.
The inability to open any books was sudden. I made no operating system changes since my previous launch of calibre. I have installed a few applications. I haven't encountered problems since their installation. Any ideas?
Here's my error message:
Spoiler:
