Thank you for the reply,
i entered the touch then tried the second one,
sudo echo kern.sysv.semume=100 >> /etc/sysctl.conf
and got permission denied?
Huh, me too. Here are the original instructions, I put them on one line to make it easier (silly me, should have tested). Instead use this:
sudo su
touch /etc/sysctl.conf
echo kern.sysv.semume=100 >> /etc/sysctl.conf
chown root:wheel /etc/sysctl.conf
chmod 0644 /etc/sysctl.conf
Enter each line one at a time exactly as above, and then reboot.
