How to customize the “About This Mac” section of a Mac
The “About This Mac” window contains information relating to your computer specifications and OS version, and is useful for quickly checking any of those details. However, it’s a little impersonal, and often (on a Hackintosh), incorrect. If, like me, you enjoy customising your machine to your own personal taste then this guide should help somewhat, by jazzing up the “About This Mac” section. If you own a Hackintosh then this guide may be of especial utility, as their non-Apple components and varied range of specifications can mean that “About This Mac” contains errors, or fails to provide any information at all. For these users the guide may be of functional use. If you’re on a real Mac, it’ll be for more aesthetic purposes.
These edits will work on macOS versions from Yosemite (10.10) to Sierra (10.12). Prior to that the file locations were different, but can still be modified with a little research. Let me know if you need any other file locations, and on which OS, and I’ll try to oblige.
Changes do not always survive a system update, though often do.
For all of these examples, BACK UP the original file to a safe location on your computer before modifying it, in case of a mistake or wanting to revert to stock later.
Changing the System Logo
This section will modify the circular image of your OS version on the main “About This Mac” page. On older OS versions, this used to be an image of your computer hardware, and I still prefer that.
1) Open a Finder window, and navigate to your /Applications folder. Find the /Utilities folder inside, and inside that, the System Information application.
2) Right-click the application and select Show Package Contents.
3) Once inside the application, look inside Contents/Resources. Find the file entitled SystemLogo.tiff.
4) Backup the original file, and then replace it with the image you want to use. It must be renamed to SystemLogo.tiff, SystemLogo.png, SystemLogo.jpg, etc.
5) After a logout/login or reboot the new image should appear in place of the pedestrian Sierra logo. For illustrative purposes I chose an image of the most pathetic piece of hardware known to Rick-kind.
For future reference, the full file path for this image is:
To revert, simply replace your backup of the original file, overwriting your edited image.
Changing the Model Name and Year
This section will change the reported hardware model and production year on the main “About This Mac” page. On a Hackintosh this page will usually report the Model you have selected in your SMBIOS settings, but you might want it to say something different. For example, for best performance on my hack, I have an iMac model set in my SMBIOS. However, the case I made for it is from an old G5, so I want that model to be reported instead in “About This Mac”. If you are on a real Mac this will likely be just, as they apparently say, “for funsies”.
1) Open a Finder window and navigate to your home User folder (the one containing your Documents, Pictures, Movies, etc.)
2) Inside that, open the Library folder. If you cannot see it, it may be hidden. You can find it with our guide. Do not confuse it with /Library by mistake, it must be /Users/YOUR_USERNAME/Library.
3) Inside the folder, open Preferences and look for the file entitled com.apple.SystemProfiler.plist.
4) Copy the file, and paste one somewhere as a backup. Then paste another copy to your Desktop to edit. Do not try to edit the file in place, it will not work.
5) Right-click the copy on your Desktop and open it with your .plist editor of choice. I use TextWrangler, which is free on the App Store.
6) In the editor, look through the file for the CPU Names entry which describes the current Model and Year of your computer. Mine originally said “iMac 27-inch, Late 2012”.
7) Edit the text in that line to report your preferred hardware name and year, or whatever text you like. Save the document and exit.
8) Drag the edited file from your Desktop back into the
/Library/Preferences folder we got it from to overwrite the original. Authenticate with your user password if required.
9) After a reboot the changes should be visible in the “About This Mac” window.
For future reference, the full file path for the document to edit is:
To revert, simply replace your backup of the original file, overwriting your edited .plist.
Changing the processor name
This setting may allow you to change the processor name, but I have had mixed results. It worked on my Hackintosh, but not on my MacBook Pro, so your mileage may vary.
1) Open a Finder window, navigate to the System folder, and then to the Library folder inside. (Not the “Library” folder we visited in the Model name section).
2) Inside Library, go to PrivateFrameworks, and find AppleSystemInfo.framework.
3) Inside this framework, navigate to /Versions/A/Resources/. Then find the folder for your system language. If yours is English, go to English.lproj.
4) Inside that folder, find the file AppleSystemInfo.strings. Copy the file, and paste one somewhere as a backup. Then paste another copy to your Desktop to edit. Do not try to edit the file in place, it will not work.
5) Right-click the copy on your Desktop and open it with your editor of choice.
6) In the editor, look through the file for the UnknownCPUKind entry which describes non-standard CPU models. Mine originally said “Unknown”.
7) Edit the text in that line to report your preferred CPU model and speed, or whatever text you like. Save the document and exit.
8) Hackintosh only, Mac users skip to Step 9.
Open up your Clover config.plist, and under the CPU section set the Type to Unknown. I used Clover Configurator for this step but it can be done manually too.
9) Drag the edited file from your Desktop back into the folder we got it from to overwrite the original. Authenticate with your user password if required.
10) After a reboot the changes should be visible in the “About This Mac” window.
And there you have it! My under-powered robot’s CPU is now correctly reported. Remember this section may not work for you, especially on a real Mac, as it will probably not default to the “Unknown CPU” field. Setting the CPU type to “Unknown” in Clover on a Hackintosh forces it to use the field, and therefore work.
For future reference, the full file path for the document to edit is:
To revert, simply replace your backup of the original file, overwriting your edited .strings file.
Changing the Displays image
This edit is one of the most useful, as many people use external displays, and they come from many third-parties. Consequently, a generic icon is used by Apple in the “Displays” section of “About This Mac”, and in the “Displays” section of “System Preferences”. Many people will wish to change this to an image of their specific external display model.
1) Open a Finder window, and navigate to the System folder. From there, open Library, then CoreServices, and locate the file CoreTypes.bundle.
2) Right-click CoreTypes.bundle and select Show Package Contents. From there, go to /Contents/Resources, and find the file called public.generic-lcd.icns.
3) Make a backup of this file somewhere safe, and then place an image of your own display, or whatever image you like, into that folder. It will replace the generic display image. Make sure the file you place there is called public.generic-lcd.icns. The file must be in .icns format. I use Image2Icon for this; it is available on the App Store for free.
4) After a logout/login or reboot, your changes should be visible.
For future reference, the full file path for the document to edit is:
To revert, simply replace your backup of the original file, overwriting your edited .icns file.
As you can see by browsing through, many other basic system images and pieces of text are contained in the files and folders we have been editing in this article. With a bit of digging you can find many other useful things to change in the locations we have been looking.
Just make sure to always make a backup of any files before changing them, and preferably to have a clone of your whole system too. That way if you delete a truly crucial file you can boot from the clone and replace it.

Question: Q: ‘about this mac’ not working
Does anyone else have an issue with the ‘About this Mac’ function?
I simply want to see how much memory I have left so I clicked on the ‘Apple’ then clicked ‘About this Mac’ as normal but there is absolutely no response?
Is there a keyboard shortcut I can use?
I have a 2011 iMAC Intel with Yosemite OS X installed and have had no issues with anything up until last night.
iMac, OS X Yosemite (10.10.2)

Thanks for the question. If I understand correctly, you are not able to open About This Mac from the Menu bar. I would recommend that you read this article, it may be able to help the issue.
You can try starting in Safe Mode, it might be another program interfering.
Follow these steps to start up into Safe Mode.
- Be sure your Mac is shut down.
- Press the power button.
- Immediately after you hear the startup sound, press and hold the Shift key. The Shift key should be pressed as soon as possible after startup, but not before the startup sound.
- Release the Shift key when you see the Apple logo appear on the screen.
After the Apple logo appears, it may take longer than usual to reach the login screen. This is because your computer is performing a directory check as part of Safe Mode.
Thanks for using Apple Support Communities.
How to find my MAC address on Mac OS X?
These instructions explain how to find MAC address on your device with Mac OS X.
The first way
Select System Preference from the Apple menu .
Then, select Network .
On the next screen select Wi-Fi and click on Advanced .
On this screen, you will see the MAC address. Also, you can click on the Hardware tab.
The second way
Select About This Mac from the Apple menu .
Then click on System Report .
Here you can see your MAC address.
The third way
Yet another way to get your MAC address on newer versions of Mac OS X is a search for the network Utility.app , if you have this, you launch the application.
Another way to find MAC address on Mac OS X is by using the terminal.

Macs have a lot of different identity numbers, settings, and other key bits of information which you will need to access at some time or other. The hardware serial number is an obvious example, but there are many others, including the hardware UUID, MAC addresses for each network port, and so on.
These and much more are provided by the About This Mac dialog (at the top of the menu), and the System Information app which is launched when you click on the System Report… button there.
If you’re unsure whether your Mac supports Bluetooth LE Continuity features such as Handoff and Instant Hot Spot, select the Bluetooth item in Hardware to see a list of those features, and a detailed list of all Bluetooth devices which your Mac knows.
If you have an optical drive installed internally or connected externally, select the Disc Burning item in Hardware to see all the formats which it supports, and burn speeds.
Extensive details of your network settings, both current and in saved locations, are provided in the Locations item under Network.
To discover whether an installed app was purchased from the App Store, and inspect its version and signature details, select the Applications item in Software. This also lists a lot of hidden apps, such as uninstallers and tools bundled with suites such as Microsoft Office. The information provided about signatures is not as detailed as that given by Objective-See’s neat What’s Your Sign?, but should suffice for a quick check.
To see what has recently been installed or updated, including silent security updates pushed out by Apple, select the Installations item in Software. Then click twice on the Install Date column header, which sorts installations in date order with the newest at the top.
System Information gives some access to selected logs, in the Software section, the Logs item, but these are of very limited use compared with a proper log browser, even Console.
One important piece of information is currently missing from System Information: if you have a UPS connected to a USB port and have set automatic shutdown in the Energy Saver pane, those settings are not shown in the Power item, nor in its USB listing. You will either have to refer to the preferences file, or the settings shown in the pane itself.
Startup problems and instability
Now that it is much harder to browse your Mac’s logs, System Information is a good place to start if you are concerned that you have old extensions or other items which are causing problems during startup or later.
In the Software section, the Extensions item gives a full listing of all kernel extensions (KEXTs), which you can sort by the Obtained from column to make it easier to check third-party extensions. Loadability, dependencies, and signature details are also given, together with the date of last modification. These can give you clues as to which extensions may be suspect.
Although the Frameworks item can also be helpful on occasion, the other important sections to browse when checking for causes of instability are Preference Panes and Startup Items.
