Invalid results from MacOS and UNIX client: Thanks to all MacOS and UNIX users for testing and giving feedback. Currently most results from MacOS clients and several results from UNIX clients cannot be validated due to minor differences to results from Linux and Windows. This is due to different rounding and is hard to solve consistently for all CPU/OS types. So we will improve the validator that compares the different results for the same workunit. In the future also similar results (same results except on rounding differences) will be successfully validated. The new validator will be implemented soon, we hope to get it ready on friday. All MacOS and UNIX users should suspend their calculations during the next days to avoid more invalid results.
