Mid 2014 Macbook Swollen after High Sierra / What should I do? This discovery came after my latest question: High Sierra&#39;s External Display bug heats Macbook&#39;s, damaged my Retina Screen, what can I do?

I use my macbook on a stand with good airflow, after High Sierra, I noticed unusual high heating along with poor gpu performance, afterwards I noticed screen damage, and now, I discovered that my macbook is physically swollen, 2-3mm's I'm guessing

The issues could be unrelated to High Sierra, yet, it would be too big of a coincidence if it's not the cause, as things were breezy beforehand

Here's a picture of the issue: https://imgur.com/a/feBG7



The trackpad area is swollen, the trackpad doesn't click any more, the battery reports "Normal" condition (Cycle count: 12), the lid doesn't close any more, but everything luckily works for now

I assume it's the battery that's swollen, but even with the high heating I complain about, the GPU temperatures was 80C at most and enclosure temps weren't extremely high

It's a shocking issue for me, I'm wondering whether there is a solution other than buying a new Macbook, unsure how to approach the issue in general, and since I use the device daily, really don't want to part with it even for repairs or inspection, I'm located in Turkey

Also curious why I experienced these issues with High Sierra and whether anyone else has similar experiences
Make a full backup and get it into a store/repair shop for inspection.
