Tags not associated in OS X
Solution 1:
- Issued sudo mdutil -i on "/Volumes/External-SSD” and got back "Indexing and searching disabled.” for external HDD.
- Defaults write com.apple.finder AppleShowAllFiles -boolean true ; killall Finder (shows all file)
- Go to hdd where indexing is not working. externalssd in my case. find locate .metadata_never_index & delete it.
- sudo mdutil -i on "/Volumes/External-SSD” started spotlight indexing and indexes are created.
- Tags working now.
This concludes that Tag functionality is dependant on spotlight and needs to be enabled.
