I've been using 10.11 beta (15A225f) on a late 2011 MacBook Pro. One issue I've run into is that although I can create and delete smart mailboxes, the changes don't stick if I quit and restart Mail.app. I've tried a number of things -- most recently deleting
BackupTOC.plist
DefaultCounts
Envelope%20Index
Envelope%20Index-shm
Envelope%20Index-wal
ExternalUpdates.storedata
ExternalUpdates.storedata-shm
ExternalUpdates.storedata-wal
LSMMap2
SmartMailboxesLocalProperties.plist
from ~/Library/Mail/V3/MailData and letting Mail.app rebuild everything, but the problem persists. I can see entires being created in SmartMailboxesLocalProperties.plist when I add something, but that file gets reset when Mail.app is restarted. Any ideas?
Thanks!!
