AI Recommendation
1 suggestionA native Apple Silicon (Universal Binary) build of pstomxb450fps has been confirmed running on real Macs in the Rosetta Check community. If you are still running an older Intel-only build under Rosetta, update to the latest version to get the native build, which will improve performance and reduce system overhead during printing operations. The simplest approach is to download and reinstall the latest Sharp MX-B450 printer driver from Sharp's support website for your region, which includes the updated filter. Your existing printer configuration will be preserved.
