Roast Time 4.3.2

Hi, I was updating the Software to 4.3.2. (Bullet 605). I could make two roast 2-3 weeks ago. Today I was not even able to use the software. Sometimes I had connection with the bullet and could start PH. Active Roast graph is not displayed at all. Can it be that RoastTime is not usable with MAC anymore? BR Ralph
