Apple are swapping my MacBook Pro, after a few issues they are swapping it for the newer model. I had 2018 6 core 2.9, 32gb ram, 1 tb, vega they will swap foe 2.4 8 core, 32gb, 1 tb, vega I can see the clock speed is lower, but with the extra cores and heat difference, is the 2.4 a better model? it is a good swap yes? I just want something more reliable for the $ I invested. I was happy with the upgrade, then someone told me that it is lower spec'd is all.
