I also just bought a Quantum 2626, does not work with my big sur M1 combo.
Please Presonus, help us out!!!
From Presonus support page about M1/Big Sur, updated dec 11.
”Support for Apple M1 Mac's will be available in early 2021.”
”We do not recommend Apple Silicon Macs for use with any Presonus interfaces, mixer products or applications at this time.”
Any luck with the new firmware update? Is working now with the m1?
