Can you elaborate on the steps? Do you think this will solve the glitchiness, slowness to load (everything)?
My normal procedure, prior to installation a point-release update like this, is to:
1) Do a git stash/pull on the Probook.git repo
2) Do a fresh download of Rehabman's software
3) Install the udpate; this usually take like 40 minutes, or so
4) Upon reboot, I'll login, noticing that WiFi again is unrecognized
(this is corrected with the brcm patch and Lilu)
5) 10.13.3 patch introduced a new wrinkle: random reboots after a brief time post-login at desktop
6) Booting into single user mode (-s option in Clover), I mount the drive writeable /sbin/mount -uw /,
and change the repo directory; in my case, Users/xxxx/Downloads/projects/Probook.git
7) From there I run Rehabman's installer script ./install_downloads (it bombs on trying to copy HP fan
control to the EFI partition; this is to be expected).
8) If this doesn't correct the problem, and I'm seeing random reboots, or Wifi is still broken, I go back into
single user mode, and run the following: sudo touch /System/Library/Extensions && sudo kextcache -boot -u /
9) Once the foregoing completes, and I'm booted into macOS, I run the commands again--reinstalling the downloads
and updating the bootcache.
I've had no random reboots since this morning, and the laptop has been on all day. Haven't tried sleep, because it usually won't wake, instead just shutting down.
