Reset Mac user password.

Got an old iMac 9.1 running OSX Lepoard in. Client needed the password reset on it, but had long forgotten it and didn’t have the Apple account it was bound to.

1. Boot into single user mode (press Command-S at power on). It’s bassically just a command line (like DOS for you PC users)

2. Type fsck -fy

3. Type mount -uw /

4. Type launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist

5. Type dscl . -passwd /Users/username password, replacing username with the targeted user and password with the desired password.

6. Type exit

Laptop Repair!


Computer came in so I could change out the fan – it was wobbling and getting loud. Came off by sliding a couple of clips, no screws. The fan has two screws and one wire, all perfectly accessible without any for the disassembly. LAPTOP MANUFACTURERS TAKE NOTE! THIS IS HOW YOU DESIGN THINGS RIGHT!

Now I’ve got to go out and disassemble an entire computer And break through a bunch of plastic restraints on a metal retaining baffle, just to change out the keyboard on a different unit. Ugh.

NO USB mouse or keyboard

 

Problem:

You start up and can’t log in or do anything. Many times customers will think thier PC has frozen, but in actuallity it’s just not loading the USB mouse and keyboard drivers on boot (finds new devices but fails the driver install). You can tell this if you see ascreen saver come on or new messages still popping up in the corner.

Solution:

If it’s not finding the driver, quick solution is to point the search to the WindowsInf folder (browse my computer for drivers). This should at least get you functionality.

Setup searches a predefined path on the drive, looking in .inf files to find the best match for the Plug and Play ID of the device. This path is defined in the following registry location and is set to %SystemRoot%Inf by default:

HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionDevicePath: REG_EXPAND_SZ:%SystemRoot%Inf

Adding an entry with the actuall path may solve the problem her. Don’t delete the current path thoguh, add a ; and then type the path
; C:windowsinf

Modify the registry to deactivate Windows

 

Problem:

The windows activation windows keeps poping up even  though windows says it’s been activated. This is frequently caused by someone using an activation crack, or by the wpa.dbl and wpa.bak files courrupting. Sometimes also happens after a repair installation of windows.

Before we can legitimatly (re)activate windows we first must de-activate it.

Solution:

In Registry Editor, expand My Computer, and then expand HKEY_LOCAL_MACHINE.
Expand SOFTWARE, and then expand Microsoft.
Expand Windows NT, and then expand CurrentVersion.
Under CurrentVersion, click WPAEvents.
In the right pane (topic area) of Registry Editor, right-click OOBETimer, and then click Modify.
Click to put the pointer in the Value data box. Then, modify any character that appears in the Value data box.
Click OK.
