For those of you following along, Emacs has been crashing on my Mac (but not on my Linux desktop) for a while, but it seemed too random to pinpoint. This led me into looking for the Darwin version in the Emacs build in Emacs for Mac OS (which was what I was using on my Mac), which was a couple of versions behind that of macOS itself.I went ahead and attempted to use Emacs Plus from Homebrew, as most people commented. I haven’t noticed much of a difference, though personally I do prefer to use Emacs from Homebrew as I do with my other packages, so I stuck with it a bit longer.Yesterday I encountered a stubborn crash in my journelly.org file. Journelly, which is basically a large org-file with pictures displayed in-line under some headers (you can get an idea of what Journelly is and how I use it here).I took a picture of the snow outside with my iPhone using Journelly, which saved it to journelly.org with the image attached. On the Mac, every time I went to open the header, Emacs crashed, time after time. I just couldn’t edit that image. In a collapsed state for the header, where the image didn’t show, it was fine. On Linux, when I tried - fine. Oh, and before you ask - I tried this with emacs -Q, and yes, it crashed every single time as well.The JPG image on my iPhone was a 7MB file with dimensions of 4284 x 5712. I knew from past experience that such large images slow down Emacs (on Linux too), so I shrunk it down to a 700kb file with dimensions of 604 x 640, and launched Emacs again. No problem. Everything was stable. I tried to load Emacs a few more times and it worked each time.This was my hunch from the beginning - that something is up with images at least on the Mac, and this is proof enough for me. I don’t know exactly at what point Emacs crashes: is it a matter of how many images the org file has? How big are they? A combination of both? But I can tell you it seems to be more about the dimensions of the image in pixels than the file size. This is fine for me, for my journal, I don’t need large high-resolution images anyway; those are uploaded and displayed on my blog and elsewhere. It seems that some folks have encountered similar issues as well, from Reddit and elsewhere.If you have similar issues and you’re fine with scaling down your images, a good solution is dwim-shell-commands-resize-image-in-pixels, part of the excellent dwim-shell-command package, which can quickly shrink down a large number of images from inside Emacs. I’m using it constantly.
