And I do not deny the evidence of such. For example:
Additionally, I will be completely forthcoming and admit to having no electrical engineering education.
However:
• The voltages witnessed are not out of spec.
• The voltage levels exhibited during a “cold” boot are also applied during normal operation (e.g. Turbo Boost period).
• Unless mods or settings notably beyond spec are applied, a chip failure is far more likely to be from a manufacturing defect, poor soldering to the substrate/PCB, improper cooling system mounting, defective/damaged power delivery system.
— Coincidentally, this recent video is relevant:
Oh, and these industry wide problems, which also affected families/series/periods of Macs:
Regular readers of Hackaday are intimately knowledgeable about old electronics, and whether it’s about that old oscilloscope sitting in the pile of other oscilloscopes, or the very rare vinta…

I was a computer technician for several years and directly dealt with these hardware failures. Another common flaw, not related to chips/ICs, was barrel plug connectors/ports (e.g. laptop power) design/implementation. Many barrel plugs had zero reinforcement, only held in place by the single solder joint supplying the center pin, plus thin plastic making up the surround/housing.
Last but not least:
• Not ideal is much different than “the sky is falling.” For example, PC enthusiasts who claim their PC will catch ablaze or melt into a pool of silicon if the CPU or GPU ever reaches 90-degrees for even a moment — my fitting exaggeration of their claims. Again, extremely unlikely as the condition is within expected and manageable parameters. But I do accept anything
can happen.
Basically, if your Mac does fail, the cause is extremely improbable to be related to (properly) shutting down and booting the system even several times a day.
I repeat:
