@BluebellfloraYes, I did the EAWebKit.so fix, and it DID work for a day or two, then started the instant crashing again. I think it's just the fact that El Capitan has the earlier version of metal, and the recent patches have made the game incompatible with Metal 1. I'd probably have to delete the EAWebKit.so file before I start my game every time. But that's a moot point now, since I can't even load a lot anymore.
From an article about APFS that was apparently released right before Mojave: "APFS currently works only with SSDs, although Apple says that full support for mechanical hard disks and Fusion drives is coming in macOS 10.14 Mojave."
The article said when installed on SSDs, High Sierra automatically switched the underlying file system from HFS to APFS. But not on Fusion drives. I don't know what Apple did to make High Sierra work on Fusion drives, but since Mojave now has full support for Fusion, that's what I'll be going to. Here's a link to one of the best articles about it I read. It's not written by Apple, so I can't speak to its 100% accuracy. 🙂

I'm probably gonna make the leap to Mojave today. Just working up the courage to take the plunge to see what kind of carnage will happen with all my older apps. haha
Worst case, I can always wipe and reinstall El Capitan via Time Machine backup if I had to.
Getting a Fusion drive in my iMac instead of the SSD was a trade off. The Fusion drive saved me a couple hundred bucks, which meant I could afford the AMD Radeon R9 M395 video card for it. My reasoning being that I was willing to sacrifice a little speed for better graphics. It was a decision I haven't regretted... until now. If I could go back and get that SSD instead, and just eat ramen for a while to afford that AND the beefy video card... oh well. Hindsight. haha
