It’s quite simple: We’ll need to take a peek inside the /proc/cpuinfo file and look at the flags section for one of two values, vmx or svm.

• vmx – (intel)
• svm – (amd)

You can use grep to quickly see if either value exists in the file by running the following command:

egrep ‘(vmx|svm)’ /proc/cpuinfo

If your system supports VT, then you’ll see vmx or svm in the list of flags. My system has two processors, so there are two separate sections:

flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall nx lm constant_tsc pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr lahf_lm
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall nx lm constant_tsc pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr lahf_lm

VT technology can still be disabled in your computer’s BIOS, however, so you’ll want to check there to make sure that it hasn’t been disabled. The flags in cpuinfo simply mean that your processor supports it.

1.) Log in as root and execute the following command:
“grub-md5-crypt”

2.) Enter the desired password and re-confirm it.
Once that is done, it will generate a md5 hash key:

e.g: $1$6OIyj/$k3tMWdt2uSFViufz1YsgF/

3.) Add this MD5 password to your /boot/grub/grub.conf by adding the following line (before the title line):

password –md5 [your hash key]

4.) Save the file and try to restart in single-user mode.

This time I like to share a small script called Lava Corners Switch. I have no idea who actually wrote it and the author of the script did not sign it off.
Just open AppleScript Editor (typing it in spotlight) or go to Macintosh HD – Applications – Utilities – AppleScript Editor and paste the following code:

property tl : 1
property tr : 1
property br : 1
property bl : 1
property runs : 0

if runs is 0 then
 set tl to do shell script "defaults read com.apple.dock wvous-tl-corner"
 set tr to do shell script "defaults read com.apple.dock wvous-tr-corner"
 set bl to do shell script "defaults read com.apple.dock wvous-bl-corner"
 set br to do shell script "defaults read com.apple.dock wvous-br-corner"

 do shell script "defaults write com.apple.dock wvous-tl-corner -int 1; defaults write com.apple.dock wvous-br-corner -int 1; defaults write com.apple.dock wvous-bl-corner -int 1; defaults write com.apple.dock wvous-tr-corner -int 1; killall Dock"
 set runs_A to 1
end if

if runs is 1 then
 do shell script ("defaults write com.apple.dock wvous-tl-corner -int " & tl & "; defaults write com.apple.dock wvous-br-corner -int " & br & "; defaults write com.apple.dock wvous-bl-corner -int " & bl & "; defaults write com.apple.dock wvous-tr-corner -int " & tr & "; killall Dock")
 set runs_A to 0
end if

set runs to runs_A

Save the file and drag it into your Dock. After that, just simply click to activate and deactivate accordingly.

First what you need to know is the location of your background pictures.
When you click on System Preferences, under Personal choose Desktop & Screensaver you will see a few folders with desktop pictures.
These folders are linked to the following location on your Macintosh HD:

/Library/Desktop/Pictures/

Now when you get your standard Mac installation, you background is set to Leopard Aurora (in the Nature folder) same as your login background.
After you change your Desktop background, your login background stays the same.

To change that you have to go to the following location on your Macintosh HD:

/System/Library/CoreServices/

In this folder you will find a file called DefaultDesktop.jpg. All you have to do is to copy your current Dekstop background picture found in /Library/Desktop/Pictures/<folder>/…jpg
to this location and rename the file to DefaultDesktop.jpg.

Note: you might need to type in your password to authorize the change.
