I am sorry to report this.
This weekend I decided to reinstall Logos 4 (stable, was not on beta). I deleted all files. I did not download the resources (10.500+ = 24+ GB) but did a "scan resources from an external disk. This worked fine.
Bible index did take 6 hours.
Indexing the other library: I stopped this, as I could not use the mac for study etc. Totally unusable when indexing is running or even when stopped for 4 hours.
Indexing was busy for more than 24 hours (I believe 26 hours) and only at 26% when I decided to stop this!! I did check the logs, no problem.
I have a new MacBook Pro, much memory etc.
Fot now, I decided not to run Logos 4 because it takes to much time. I am reading from my Ipad now.
What can be the problem. Is this normal? Even with a very large library? I have about 400 personal books that are also being indexed. Should I leave these out for the moment?
I have done reindexing before, but did not encounter these problems then.
