Welcome to the club, Richard! I also had an error that showed up at about 9 P.M. on Saturday, with Easter services just 12 hours and 30 minutes away. I think my error was also caused by cloud storage but I'm not sure what caused the problem. The result for me was that I had no Songs database. I thought about uninstalling and doing a fresh installation, but I feared getting into a situation like yours. Ultimately, I created my songs for Sunday morning using Custom Slides. That was a painful exercise, but a lot better than some of the alternatives I might otherwise have had. I'm still considering what my next move will be. I've sent my logs - 3 or 4 of them, I think - to the developers. I'll see what happens after that. The other thing I encountered was confusing 'warning messages'. Despite reading these messages numerous times, I was still confused about what they were warning me about.
Your data should have been located at:
/Users/~/Library/Application Support/openlp/Data
This is the standard location for OpenLP to install the data files on macOS. The Mac I'm typing on is running macOS 11.7 (don't ask me about the names, please). The same location is used on my newer Mac which is running macOS 15.4. As is standard in Mac notation, the tilde ~ represents the home folder of the current user. I think that Application Support folder, and therefore any folder below that in the structure, is a hidden folder by default in macOS. Normal searching won't necessarily find the folders/files that you're looking for.
**To get to Terminal, the easiest method to explain is to press and hold the Command (⌘) key and press the space bar. That brings up a window called 'spotlight search'. In that window, type Terminal, then press Return.
If you don't have any 3rd party tools to allow you to see 'hidden' files and folders, then go to Terminal and type
defaults write com.apple.Finder AppleShowAllFiles true
press return
then type
killall Finder
and press Return
You'll now be able to see all hidden folders and files. They'll be a light grey colour compared to other, regular files and folders.
When you have finished with the hidden folders and files, it is a good idea to hide them again. So, back to Terminal and type:
defaults write com.apple.Finder AppleShowAllFiles false
then press Return;
After that, Type:
killall Finder
then press Return
I don't know how much you know about your Mac, so please forgive me if I have covered basic things that you already know.
@PaulRowell will help you with more things than I can, I'm sure. I have just been trying to fill in the gaps of his macOS knowledge. However, if I can be of any help, please give me a shout out.
Blessings,
Andrew
