Soulver saves your sheets into a file called a sheetbook.
Your default sheetbook is stored inside Soulver's application support folder at
Or, for the Mac App Store version, here:
You can move the default sheetbook to another location in Soulver's General preferences.
Soulver can only open one sheetbook file at a time, so if you open another sheetbook file, your previously open sheetbook will be closed.
You can open a sheetbook by double-clicking a sheetbook file in Finder, or through the Open dialog.
On the first Mac, go to Soulver > Preferences > General, and choose "Move…" under
Sheetbook Location to move the sheetbook into a synced folder, like Dropbox or iCloud Drive).
On the second Mac, double click the sheetbook file in Dropbox or iCloud Drive, and it will open in Soulver.
Soulver makes daily backups of your sheetbook, just in case. To restore from a backup, go
File > Backups, select a backup and click "Restore from Backup".
If you prefer working with files saved in Finder, you can create a Soulver File.
