How was that an attack? If a later beta is more unstable then the previous version then Apple should quit if they are doing that bad of a job, it’s just a very good chance that the newer version is going to be more stable even if it’s 1% improvement from the previous one.It’s called human nature. Beta 8 is really good, even speedier (as per Geekbench).
Why not providing feedback about the new Beta instead of attacking a candid comment?
