I updated to 15... that's the hint there was another number, it seems Apple dont have there GUI sorted to show hidden numbers after the dots. 18.0 was just that without the hidden hint, although it did tell you underneath the update. Seems to have helped with a few issues, running well on my M2 Pro mac Mini Pro that I wont be updating to a toy puck after only a year of owning this one, which does all I need it to at this point. I'll be on the M27 SoC route I think, as I gave this one plenty of ram and a nice fast 1TB SSD. Also I wont loose USB C ports for my APC UPS with an adaptor as my 1000 watt smart UPS only has USB 1.1 ports.
