MacOS Tahoe
MacOS Tahoe beta was released June 9, 2025 and seems to work with BigBusiness 15.
Tahoe is the last version of macOS to work on Intel Macs, using chips like the i5 or i7. BigBusiness 15 is native for Apple Silicon, their new chips such as M1, M2, M3, M4.
Earlier versions of Big Business are no longer updated and are not supported on Tahoe.
