Hi I have read in the documentation that Sugar on a Stick does not work so well on Mac computers and that from a testing point of view the best thing is to use a virtual machine. I am wondering if anyone can give me advice on the best option for testing sugar activities using a Mac and virtual machine. I have tried Sugar (Strawberry, Blueberry, and Maribelle) on (Oracle) virtual box version 3.28... but have not been able to install the TamTam activities satisfactorily on Maribelle, while on Blueberry the sound is glitchy and disjointed. Maybe some one has a suggestion? Many thanks. Sean
