Hello
I'm trying to use Calibre for the first time. I've downloaded the latest version, including the KFX plug-ins but when I try to 'customise the plug-in' so I can add my Kindle device serial number I get an error message.
I'm running MacOS Sequoia v.15
Have tried the usual uninstall, reinstall, restart and continually get same error message
I'm assuming this may because of the latest MacOS update but is there anything I can do?
Thanks in advance
