    Hi all

    Here in London, we're witnessing a rare miracle with our mini-heatwave like weather. I therefore wanted to ask people who live in predominantly hot areas, how their retina MacBooks cope with their fan-less designs.

    I want to visit LA next summer for around 3/4 months and am just curious if the rMB will cope with hot temperatures, as in using the rMB in the garden/outside etc.

    Don't worry about it. It'll be fine.

    I have a surgeon friend who lives in Chad. Typically it's 108 deg F. No problems. I've asked as I expected overheating to be an issue. Nothing after 6 months with a 2015 model.

    I am in Bangkok. The last few weeks were around 38-44C. The Macbook did get warm but operating fine.

    You may notice some performance decrease under a heavier load due to the CPU/GPU throttling more easily. Likewise, battery life may be a bit lower as transistor leakage increases with temperature, but there's nothing you should really worry about. The impact of ambient temperature is the same with all devices, regardless of whether they are fan-less or not.

    Obviously, you should avoid direct sunlight for extended periods of time because that has the potential to cook the internals, but you don't really want to be in the sun during a summer day in LA anyway.

    Bought the rMB 10 days ago and living in Dubai, UAE where temperatures have started to hit 40*C (God's been kind this year, temperatures usually hit 45*C by this time). There are air conditioners everywhere so the weather is ideal for the rMB to work. Actually come to think of it, the weather doesn't play any role in this scenario.

    Although, sitting outside in temperatures over 32*C is suicide to begin with.

    Works fine, I would imagine that you would need to be in an ambient temp of 40C + which is more likely to impact the battery. Currently I am in Southern Vietnam with my 2015 1.2 rMB admittedly it`s mostly under the AC, however it does get used outside with the temperature being around 34C - 38C

    Thanks for the input guys! I should be ok then, as looking at rumours, I don't think the redesigned rMBP is going to be lighter than the current MBA, so I'm gonna keep the rMB as my daily laptop machine for at least the next year or so.

    I would be more concerned for you than the rMB sitting in >40C here in UAE :)
