Thank you Konstantin. I enabled the service changed characteristic but it still did not work on Mavericks. I ended up just upgrading my Macbook to Yosemite and now it works :) Spent too many hours on this... just gave up.

This is the script to clear OSX BLE cache:

sudo defaults write /Library/Preferences/com.apple.Bluetooth CoreBluetoothCache -dict

sudo launchctl unload /System/Library/LaunchDaemons/com.apple.blued.plist

sudo launchctl load /System/Library/LaunchDaemons/com.apple.blued.plist

Both OSX and iOS will buffer Attribute tables/profiles. If you want to avoid that you should enable the service changed characteristic. If this is enabled they should redo service discovery when reconnecting to a device that isn't using bonding. If you are using bonding, the attribute table will be buffered until a service changed indication is sent from the peripheral.

On iOS you can "flush" the buffer by toggling Bluetooth off then back on. I guess you can try this on OSX as well. However if that doesn't work you could try to delete the bluetooth.plist to force it to forget the device.
