Calibre stuck on "initialising user interface"

[zupa_pomidorowa]

Hi all,

After a few years of smooth operation, Calibre suddenly stopped working. It gets stuck on the "initializing user interface" dialog whenever I try to open it. I have tried everything - rebooting the computer, upgrading Calibre, downgrading Calibre, deleting Calibre from disk, and installing it again - no luck. I would greatly appreciate any help.

Try running as

/Applications/calibre.app/Contents/MacOS/calibre-debug -g


from Terminal.app that will give you more debug information

This is what I get:

lukasz@Lukasz-MBP-3 ~ % /Applications/calibre.app/Contents/MacOS/calibre -debug -g

Usage: calibre [options] [path_to_ebook or calibre url ...]

Launch the main calibre Graphical User Interface and optionally add the e-book at
path_to_ebook to the database. You can also specify calibre URLs to perform various
different actions, than just adding books. For example:

calibre://view-book/test_library/1842/epub

Will open the book with id 1842 in the EPUB format from the library
"test_library" in the calibre E-book viewer. Library names are the folder names of the
libraries with spaces replaced by underscores. A full description of the
various URL based actions is in the User Manual.


Whenever you pass arguments to calibre that have spaces in them, enclose the arguments in quotation marks. For example: "/some path/with spaces"

calibre: error: no such option: -d

you have inserted a spurious space between calibre and -debug remove it and try again
