I just received mine fully spec refurbished model (32gb, 2tb, 2.4 8core, gpu 8gb) on monday and used it for 12 hours or so and had heating issues for the first 2 hours of setting it up..the area above lid was so hot with fans going crazy. I spoke to apple support and did tests etc., and i decided to install all my apps on it and see if will calm down over time. Then those kernel panics showed up in the morning after I opened up the lid. Heat issues still persistent after that even when running safari. The manufacturing date was nov 2011. Apple support told me to just return it for now as i still have my 13" mbp 2013. I had to cancel my amazon order for case and dongles etc..blah.
It's ok, It was my first new laptop in 7 years and i did like the new form factor, However, I realized that my laptop habits won't transition well to the big foot print since I sit on couch, in bed and only sometimes on the table, so it was awkward adjusting to it. I also had hard adjusting to the keyboard , as its reach, due to the larger trackpad being so wide makes me have most of my palm and hand stretched over. Another thing I notice was the 32gb ram it had, it said i have 10 gb remaining when i was doing apple mail, browsing and word open and doing small tasks like that so wasn't sure what was eating the ram up so much. This was all after the latests Catalina updates. Also when scrolling down in safari , maybe the refresh rate being at 60hz had something to do with, but was blurry as you scroll not sure how to explain it.
I can wait i guess for 14" and see how that goes. It was a fun 12 hours though. I did like the mbp 16" and immersive screen!
