We understand that not everyone has upgraded to 10.9 so we would like to extend a public invitation to help beta test the new and improved UPR: Mac legacy build. Please make sure to submit any bugs or crashes that occur by creating a support ticked and including helpful information like screenshots and console logs.
Happy testing!
Brendan Boyle
Attached is a zip file containing version 1.3 of the legacy beta. Stay tuned for updates!
