Plausible, yes, but I had a somewhat similar experience with a 2017 MBAir, upgraded to Catalina, device operated normally and then I experienced a fan noise, I had never experienced, battery drained nearly instantaneously, I put the device to sleep, plugged it into the Apple MagSafe charger, when I returned to the device it was dead, would not turn on, would not charge, I took it to an Apple certified repair shop (not an Apple store) in Bellingham WA and was informed that it must be the motherboard but they could not tell because they could not get the device to operate to run diagnostics. I called Apple customer service and though the apple customer service representative was a cordial individual I was continuously made to feel as though I simply did not have the technical/engineering expertise to grasp the fact there was simply No Way a Software Update could cause my issue. But, if I wanted to pay an estimated $500 to Apple they would diagnose my problem but it was possibly caused by moisture damage, such an assertion by an Apple representative over the phone who had never even looked at my device as a comically sad attempt at gaslighting me. The whole ordeal remains very unfortunate for me as I am now left with a 2017 MBAir device with a poor return on my investment for repair versus replacement cost. Yes, I could purchase a new Apple device, and I have left them sitting in my Apple online store “shopping basket” several times over these last few weeks only to not make that final click and purchase the product, I simply do not trust Apple to reasonably stand behind its devices and software. Finally, additionally, there are real world human costs to and even the loss of lives of workers and child laborers when companies like Apple, who through their business practices build in obsoletion of their products through both intentional and unintentional behaviors.
