I had the same issue reported on a project of mine: https://github.com/msiemens/HypheNN-de/issues/6. I was able to reproduce this with macOS 13.5 on a Mac Studio M1 Max, Python 3.11.4 and Tensorflow 2.13.0. I installed the tensorflow-metal plugin in a virtual env using pip (following https://developer.apple.com/metal/tensorflow-plugin/). In my case, the model barely reaches 94 % accuracy using tensorflow-metal, compared to >99 % without it (72 % vs. 98 % in validation).
