LS 4.0.1 broke startup of High Sierra b3

[mkummer]

V. 4.0.1 came up this morning with a message for installation. I run a public beta 3 of High Sierra on my 5k iMac w/o problems. After the installation the restart of the system went as usual until the progression bar of the startupscreen under the white Apple was full. Even after lunchbreak of 1 h the Mac had not started but was stuck. An additional startup did not change anything. I tried as proposed starting in save mode, but the startup did not finish either. No I am on a dead end and have no idea or option what to do next to get my macOS back. Any help would be greatly appreciated.

Thanks, Michael

Same here.
Booted into Recovery and removed LittleSnitch.kext from /Library/Extensions/ of my system (not recovery's) through Terminal. It helped.

Thanks - since I am not a „terminal man“ - can you be more specific, what exactly you did?

Same mac (iMac (Retina 5K, 27-inch, Late 2014)). Same problems. Had to re-install OS (bêta 10.13 (17A315i).
Working fine now.
LittleSnitch still there and working.
LittleSnitch.kext still in system extensions.

- Booted into Recovery
- Launched Terminal
- Ok, maybe the following step is a little bit weird.. but for me it was the quickest path - launched 'Disk Utility' from it, like:
/Applications/Utilities/Disk\ Utility.app/Contents/MacOS/Disk\ Utility
In Disk Utility I mounted my system's drive.
- Closed 'Disk Utility'
- In Terminal I removed the following directory:
rm -rf /Volumes/<your system's drive name>/Library/Extensions/LittleSnitch.kext
or just rename it somehow.
- Rebooted
- Spinning circle, after which system successfully booted.

Hi, how did you re-install?

Thanks for that. Good to know, there is a fallback.

Hi, how did you re-install?

After hours of trying everything I resolve to try something else.
Pressing D key at startup brings to a screen where one of the 4 choices is to install OS again. Was surprised that it offered HighSierra. Three hours later my mac booted again with the latest beta like if nothing happened. And LittleSnitch was there, doing is things.

Does removing "LittleSnitch.kext" makes the app to become useless?

Right now I am reinstalling - hope it works as well.

W/o the LS.kext it does not work.

Thanks, the reinstallation did the trick - all is well again. Pew!

MBP Late 2013
Only one thing changed after reinstallation: grey background to my wallpaper, otherwise the same: booted, entered password, progress bar went fast to approx 85-90%, then slow to 100%, then stuck.

During installation it tells me that
“/System/Library/Extensions/lspcidrv.kext” was installed improperly and cannot be used
by messagebox, pressed the only button, installation continued.

Did you reinstalled OS (version?) or LittleSnitch (version?)

[masaga]

mine broke too: exact same process...
instead of this procedure (https://www.obdev.at/products/littlesni ... notes.html) it came to this:

installed OSX sierra beta new. wanted to try another install of ls 4.0.1 ... same sad story

[sqeeezy]

me too, "fixed" by booting from backup hd and renamimg snitch kext in myHD/Library/Extensions, using Finder to rename as it was just as easy as rm (and I'm paranoid wrt rm

reboot alles klar

sent email to obdev in case he's not aware of it

btw can i just copy in my old kext from my backup? I'll try anyway

- In Terminal I removed the following directory:
rm -rf /Volumes/<your system's drive name>/Library/Extensions/LittleSnitch.kext


This Worked. Able to start OS again without a hitch. Little Snitch is also working. Thank you
