This trick is now working with the latest 1.8.8 prerelease! Tested and works same as the previous method
Several other people were part of this discussion. Would anyone else be able to elaborate on whatever the trick is? I've edited the JSON files, file names, and folders in a variety of ways, from simple (e.g. the first 1.8.7 entry in the Optifine JSON), to overly complicated, but nothing has worked. My poor laptop would love any help anyone can contribute. I doubt I'll say anything more about this....seems to be a losing battle. I imagine Optifine 1.8.8 may not even get released, what with the imminent release of 1.9. Oh well. I'll be grateful when we do get a new version.
