Downloaded it last night and it failed @ the 50% mark.
Sent my 8130 into "Brick" mode
Took an hour to unbrick
Lost: Browser Apps - Games - Calendar Contacts - and more
Do Not use DM for BB for Mac (v1.0.1) until Blackberry puts out a patch.
If you are brave and still want to use it -
MAKE SURE YOU HAVE A WORKING BACKUP.
