How to Change Mac Configuration in System Information

Yesterday I wrote about how to find out the MAC address of a computer, and today we will talk about changing it. Why might you need to change it? The most likely reason is if your provider uses the binding at this address, and you, say, bought a new computer or laptop.

I met a couple of times about the fact that the MAC address cannot be changed, because this is a hardware characteristic, and therefore I will explain: in fact, you really can’t change the MAC address "wired" in the network card (this is possible, but requires additional hardware - programmer), but this is not necessary: ​​for most network equipment of the consumer segment, the MAC address set at the software level by the driver takes precedence over the hardware, which makes the manipulations described below possible and useful.

Change MAC Address in Windows Using Device Manager

Note: the first two digits of the presetMAC addresses do not need to start at 0, but end at 2, 6,A orE. Otherwise, the switch may not work on some network cards.

To get started, start the Windows 7 or Windows 8 (8.1) device manager. A quick way to do this is to press the Win + R keys on your keyboard and type devmgmt.mscand then press the Enter key.

In the device manager, open the “Network Adapters” section, right-click on the network card or Wi-Fi adapter whose MAC address you want to change and click “Properties”.

In the adapter properties window, select the "Advanced" tab and find the "Network Address", and set its value. For the changes to take effect, you must either restart the computer or disable and enable the network adapter. The MAC address consists of 12 digits of the hexadecimal system and you need to specify it without using colons and other punctuation marks.

Note: not all devices can do the above, for some of them the “Network Address” item will not be on the “Advanced” tab. In this case, you should use other methods. To check if the changes have taken effect, you can use the commandipconfig /all (more in the article on how to find outMAC address).

Change MAC Address in Registry Editor

If the previous option did not help you, then you can use the registry editor, the method should work in Windows 7, 8 and XP. To start the registry editor, press Win + R and type regedit.

In the registry editor, open the section HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control Class

This section will contain several “folders”, each of which corresponds to a separate network device. Find one of them whose MAC address you want to change. To do this, pay attention to the DriverDesc parameter in the right part of the registry editor.

After you find the desired section, right-click on it (in my case - 0000) and select - "Create" - "String parameter". Name him Networkaddress.

Double-click on the new registry setting and set a new MAC address of 12 digits of the hexadecimal number system, without using a colon.

Close the registry editor and restart the computer for the changes to take effect.

Yes, and it won’t work - after rebooting, the iron registers it back. So just either change the iron. either bypass software. google forums have enough info!

Change the system logo

In older versions of macOS, the About This Mac menu had a computer image, and many people like it more. It is easy to return or even replace with any picture. This is done as follows.

  1. In Finder, go to the "Programs" → "Utilities" folder and find the "System Information" application there.
  2. By right-clicking on the icon, select "Show package contents."
  3. Go to the Contents → Resources folder, find the SystemLogo.tiff file there and save a copy of it.
  4. Replace it with the image you want to see, renaming it to SystemLogo.tiff, SystemLogo.png or SystemLogo.jpg.
  5. Log out or restart your Mac for the change to take effect.

To return to the standard icon, you need to move the original file into place.

Change the model and year of manufacture

The Mac model in the system information changes not much more complicated.

    Click in Finder Command + Shift + G and browse to the folder

/ Library / Preferences.

  • Locate the file and save a copy of it.
  • Make another copy of this file and place it on your desktop.
  • Open the file from the desktop in any code editor, for example, in the free TextWrangler, and find the line with the original computer model.
  • Replace it with another, or even insert any text you want.
  • Save the file and move it to / Library / Preferences, agreeing to a replacement.
  • Restart your Mac for the change to take effect.
  • In such a simple way, you can tweak the configuration of the Hackintosh assembly or "turn" a regular MacBook Pro into an older version with a touchbar, as I did.

    To return to the default settings, you need to return the original file to its place.

    Change the processor model

    Move on. Even in the same Mac different processor models can be installed, and processor information can also be changed. On Hackintosh, such a focus works completely, but on a Mac, it doesn’t always work.

    1. In Finder, click Command + Shift + G and go to / System / Library / PrivateFrameworks.
    2. Find AppleSystemInfo.framework and open it.
    3. Go to the folder / Versions / A / Resources / inside the framework and find the folder with your system language. For example, ru.lproj for Russian.
    4. Save a copy of the only AppleSystemInfo.strings file there, and then create another one and move it to your desktop.
    5. Open a copy of AppleSystemInfo.strings in the code editor and find the UnknownCPUKind section.
    6. In the lines “Unknown” and “Unknown” write the name of the processor and speed, respectively.
    7. Save the file and move it to /System/Library/PrivateFrameworks/AppleSystemInfo.framework/Versions/A/Resources/ru.lproj, agreeing to a replacement.
    8. Hackintosh users need to open config.plist in Clover and set the CPU type to Unknown. Mac owners continue to the next step.
    9. We restart the computer for all changes to take effect.

    On a Mac, it may not work, because the processor will determine correctly. But on Hackintosh, where we force the processor type, the trick will work.

    Change the display icon in the "Monitor" section

    This option is one of the most useful, since many of us use external displays and no one will refuse a beautiful icon of their monitor. And changing it is quite simple.

    1. Click in Finder Command + Shift + Gbrowse to the / System / Library / CoreServices folder and find the CoreTypes.bundle file.
    2. In the context menu, select "Show Package Contents", go to / Contents / Resources and find the file public.generic-lcd.icns.
    3. Make a copy of this file and replace it with your picture in the .icns format (you can use the free Image2icon utility for conversion).
    4. Log out or restart your Mac for the change to take effect.

    You can return to the original values ​​by moving the original file in place.

    All of these tips let you change data exclusively in the About This Mac menu. Therefore, if you doubt the veracity of the configuration, for example when buying a used Mac, it is worth checking the consistency of information through the Apple Hardware Test, which will conceal nothing and show everything as it is.

    1) Editing through the Terminal

    The terminal allows the user to perform actions on behalf of the root administrator. And this means that every computer file will be subject to you. We hope it makes no sense to warn you of the dangers of having such power,)

    There are several built-in editing tools in the Terminal itself, for example, commands nano and vi. Using them is simple. First you need to acquire root administrator rights. Enter the command:

    Then blindly enter your password and press Enter.

    Now just enter:

    nano /Library/Preferences/SystemConfiguration/

    Or you can enter nano and a space, and then drag the edited file into the Terminal window. It remains to press Enter. Working with the vi command is exactly the same.

    But editing a file in this mode is not a pleasant pleasure. Judge for yourself: no mouse control is expected here, and even the cursor will have to be moved from the keyboard.

    Useful advice: to exit nano, close the Terminal or press Ctrl + X on the keyboard.

    2) Launching a text editor with administrator rights

    The second way is more elegant. It will allow you to use regular Mac OS X programs for editing text, but run as administrator. In this case, no access rights errors will occur.

    Launch Terminal, enter sudo -s and password. Then you will need to enter a bulky design like:


    Note: through the Terminal, you need to run not the program itself (i.e. the file), but its binary, hidden inside the program, in a subfolder Contents / MacOS.

    After that, TextEdit will be able to work perfectly with any files, but only until the first close of the program.

    3) Third-party specialized programs

    We can not recommend the text editor TextMate. This is an advanced version of TextMate, which was made for programmers, but will be useful on every Mac (and even more so on a hackintosh). At your service - visual formatting of text, work with a variety of encodings, and most importantly - support for working with protected files without additional fraud in the Terminal.

    When saving a protected file, TextMate will prompt you to enter a password, and without any problems will save all the changes.

    However, the price is clearly not the advantage of TextMate. After the end of the 30-day trial you will be asked 39 euro. The developers make excuses by pointing out a huge number of built-in modules for processing various scripts and programming languages:

    But why are they an ordinary user? If the price does not deter you, then you can download TextMate from the link below:
