Apple Event: May 7th at 7 am PT
Upgraded my MacBook Air to Mojave and I can't connect to the internet at all and the system is extremely slow. I saw many posts back in October 2018 but never any clear solution even though many users had the same issue. Did anyone come up with a solution? Any advice would be helpful.
iMac 21.5", 10.11
I was not able to restart in "Safe" mode, but the following worked for me. I tried this earlier in my trouble shooting but had my spacing wrong. Once completed Mojave is working great and my machine is back to full functionality.
IMPORTANT: Make sure your spacing is correct when typing ls -l /etc/sysctl.conf into the Terminal.
A. If you can log in (even if slow), or you're still on High Sierra, and have not yet upgraded, follow these instructions:
1. Start the terminal app from Applications/Utilities
2. Check if the file exists, by typing
ls -l /etc/sysctl.conf
If this returns a result like the following, then the file exists. If it does not, then your issues are caused by something else
-rw-r--r-- 1 root wheel 136 24 Nov 2013 /etc/sysctl.conf
3. Simply rename the file by typing in: sudo mv /etc/sysctl.conf /etc/sysctl.conf.bak
(You’ll be prompted for your password)
4. Restart your computer, and you should be all set, or if you've rolled back to High Sierra, you should be good to attempt the upgrade again.

Please determine if the same problems occur in "Safe Mode": Use safe mode to isolate issues with your Mac.
Observe its operation in Safe Mode, long enough to be able to describe how it works.
Then, restart your Mac normally and determine if the same problem exists.
Hi
I know you did something great, just do not understand what it is?
It does not find the file ?
ls -l /etc/sysctl.conf
ls: /etc/sysctl.conf: No such file or directory
on High Sierra
Updated to Mojave and can't connect to internet via WiFi or Ethernet
