The patch worked a treat. I've uninstalled latebloom, and the system booted up quick and easy.
As one possible "troubleshoot" for folks who are comfortable enough to poke around OpenCore, but not quite knowledgable enough to know 100% what they're doing . . .
If you're like me and haven't done any OpenCore kernel patches, then that section of your config.plist may look like this:
Code:
<key>Patch</key>
<array/>
In that case, you need first to change that section to:
Code:
<key>Patch</key>
<array>
</array>
And then paste the patch right
after the <array> line. (The previous <array/> code says there's nothing in that array . . . you need to tell it there's now stuff in there before pasting the patch.)
Of course, after any tweaks to your config.plist, you should be verifying that file, as laid out in the instructions in the
OpenCore thread.
