Move to new Mac having trouble

pjcinoz · 11-29-2020, 06:04 AM

Folks,

I found the user manual page for moving the calibre library to another computer, also a Mac. I followed the instructions, had a couple false starts and redid steps. At conclusion, it appears to have imported the two libraries into the destination folder but when I open the app it verifies, icon bounces a couple times, and then quietly exits. I am stumped.

I spent several days on one Mac repairing entries and once completed decided to move it all to the Mac that shares with the household. I used the export routine to a clean folder, copied that to the new Mac. Reinstalled calibre and went thru the Welcome routine. The destination folder was not empty so I deleted the items there and also went into Terminal to delete the '.DS_Store' file there to make it truly empty. I then used the import routine and it appeared all went well.

As I mentioned, calibre appears to attempt a launch but then quietly quits. Any ideas? Is there something that I am missing?

Open Terminal.app in it type

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

and post whatever output appears.

That indicates that something on your computer is deleting the sockets calibre uses to communicate with its worker processes. These sockets are created inside the temporary directory on macOS. You can probably fix the issue by telling calibre to use a different temporary directory by setting the CALIBRE_TEMP_DIR environment variable, as described here: https://manual.calibre-ebook.com/cus...ment-variables

I set the environment variable as described and did a number of other things. I still get the same behaviour. After working on it off and on for a couple of days, I am abandoning the export/import project for calibre. The application and database work well on my laptop. Since I am the only one access the ebook PDFs, this should be fine.

By the way, things I tried? environment variable; disabling the firewall; logging out and doing everything in a clean admin account; downloading CleanMyMac and doing a full uninstall of calibre and all the supporting files throughout the system (calibre had no uninstaller as near as I can tell; a simple drag to trash earlier left items); a reinstall and start over after the usually clean and verify empty for the destination folder. All looked good, calibre quit after the import. Attempt to launch bounced a few times in the Dock, the splash screen displayed and it quietly quit... i.e., the same behaviour. I ran the debug command and it looked the same. I give up.

Well for the next release I have changed calibre to not use named sockets for IPC, which means whatever it is on your system that is deleting the sockets, cant do it anymore.
