  • If you watch WWDC, they shared how it works. They have a private cloud that does not persist data on it, only processes it. Also, it’s audited by a third party and there is a cryptographic mechanism that will not allow your request to be accepted unless the server software has been publicly signed by the auditor. At least, this is my best understanding of it from what I remember.

    Also, in the same presentation they announced that you can now lock your Apps and hide them, which will keep its data out of the OS search results. I am fairly certain this also means it’s opted out of ML/AI processing given that any LLM would rely on the same search index.











  • Look up the model number. There are some that maintain 100% capacity down to negative temps, and there are some that lose capacity as the temperature outside drops. You can look up something called a “submittal data sheet” to find out the output capacity at different temperatures.

    Capacity is measured in BTUs. So, if the heat pump is a 30,000 BTU model and it’s 47 degrees outside, it may produce 30,000 BTUs. However, at 17 degrees outside, it may only produce 20,000 BTUs. At -5 F, it may only do 10,000 BTU. Other models will keep 30,000 BTUs all the way down to -15F. The trade off is they use more electricity. Checking the data sheet can help you figure out what your model is capable of.

    Mitsubishi is generally regarded as the best brand and they sell a line called “hyper heat.” These maintain capacity in low temps. Other brands have similar.
