You receive an error, "Logos Bible Software (or Indexer) quit unexpectedly" or the Logos application closes abruptly while opening or performing a specific task.
Note: It is not recommended to attempt these solutions unless the problem occurs more than once. Sometimes an external variable can cause a "fluke" or one-time crash. These instructions are intended to resolve a recurring issue.
Solution 1: Update Logos
Most "crashes" occur if Logos is out-dated and has not had an opportunity to auto-update. They can be avoided by manually updating or replacing the application file.
- Quit Logos and open Finder.
- Navigate to the "Applications" folder.
- Locate the Logos Bible Software application.
- Move it to the Trash (does not delete books or index).
- Download the latest version.
Tip: It is also recommended to run Software Update to ensure your Mac has all the latest updates from Apple.
Solution 2: Check Font Book for Corrupt Fonts
Logos loads fonts from the Font Book when opening. If an incomplete or corrupt font has been detected, Logos may crash while loading it. Use the steps below to check for and remove bad fonts.
- Download the MacFontTest Tool.
- Extract the FontTest application (if it didn't extract automatically).
- Open FontTest.
FontTest will attempt to load all fonts in the Font Book. If a bad font is detected, an error will be displayed. Delete the last font loaded before the error, then repeat this process until no errors occur.
Solution 3: Validate your Fonts
If the MacFontTest Tool does not find any bad fonts validating and removing fonts that have errors can resolve some crashes. Apple's support article will show you how to validate the fonts. Do this with all of the fonts on the machine, and remove any that exhibit errors.
Solution 4: Report the Problem
If the above steps do not resolve the issue, please visit Diagnostic Logging for Mac to report the issue. Including specific steps you took to cause the crash will expedite the troubleshooting process.
