I'm on a M1 pro and the lastest combination working is Python 3.11 with tensorflow 2.15 and tensorflow-metal 1.1.0, both installable py PyPi. It has been reported that keras 3 makes no use of the GPU (at least on macos), but I have not tested this. tensorflow 2.15 ist the last version with keras 2. If this does not work for you, it could be an issue with the M2.
