You can update to Light Blue 6.1.4 b1 by using the ‘Check for Updates’ command, which can be found in the Light Blue menu on a Mac or in the Help menu on Windows.
Apple released macOS Sierra last week, and by most accounts it’s a good, stable update to macOS. We’ve heard very little about incompatibilities and Light Blue is running well on it, with one potential snag.
Sierra introduces a new iCloud feature called Desktop & Documents sync. This moves the contents of your Desktop and Documents into iCloud and syncs them across all of the devices that are linked to your iCloud account. While it’s convenient for a lot of Mac users, photographers might find this a bit problematic in that if you’ve got a lot of data in these folders (big piles of RAW files all over your Desktop, anyone?) then you’ll quickly run into iCloud’s storage limits unless you upgrade to one of Apple’s more expensive iCloud plans. You can find out more about how these feature works (including some scary things that can happen while setting it up, or turning this feature off again) here.
More importantly, this new synchronisation feature has the potential to interfere with Light Blue’s own data and file syncing. Therefore, we’ve released an update that moves Light Blue’s data folder to a location that won’t be affected by this feature.
All you need to do to ensure that your copy of Light Blue 6 doesn’t run into this potential problem is to update to version 6.1.4, and we strongly recommend that you do so before upgrading your Mac to Sierra. Light Blue 6.1.4 will automatically move its data folder to a new, safer location: ~/Library/Application Support/com.lightbluesoftware.lightblue/
This new data folder location is less convenient for anyone who wants to manually create or restore backups, but avoids any potential problems caused by this new iCloud feature.
Versions of Light Blue older than Light Blue 6 store their data in a different location, and aren’t affected by this new iCloud feature.
