There are times when you wish to check various information of your MacBook, like whether your Mac is dual-core or quad core, its warranty, RAM Type, which generation of processor your Mac has etc.. We will tell you each and everything you may need to know about your Mac.
How to check Which MacBook’s Model, Processor, number of cores, Processor’s clock speed, RAM, and Serial Number
- Click on Apple icon (located at the top left corner by default)
- Click on About this Mac
- Click on System Report
The screenshot makes everything clear. Please note that when number of cores are 2, it means your MacBook has dual-core processor. If the number of cores are 4, it means your Mac has quad-core processor. Only 15-inch 2011 or later models with core i7 processor has quad-core processor as far as MacBook Laptops are concerned. However, you can always check this way to remove confusion.
The screenshot still doesn’t define the RAM type and Speed and processor generation. We will tell you how to check
How to check RAM detail on Mac
Under the same window (System Report), click on Memory, and you will find the following screen
As you can see, in my Mac there are 2 RAM slots (that usually all Macs has), and its DDR3, and has 1600 MHz speed. You may find the speed to be 1866 MHz in some newer models, like 13-inch MacBook Pro Retina 2015 model.
How to Check what generation of Processor Mac has
Processor Generation doesn’t appear in System Report Section. You need to check it via Terminal. Follow these steps
- Launch Terminal (located under Application –> Utility if you open via Finder, Or just press Command+Space to bring spotlight search, and Type Terminal, hit Enter to launch)
- Type the following command in terminal, and Press Enter
sysctl -n machdep.cpu.brand_string
You will get the Processor information like below Screenshot. In my case it has a i5-4278U CPU @ 2.60GHz, that’s 4th Generation. Number “4278U” is used to define Processor Generation. If the number starts with 2, it means it’s 2nd generation, If with 3, it means 3rd generation, if it starts with 5, it means 5th generation processor.
How to Check Mac’s Warranty, and what if Warranty Status doesn’t appear
The warranty of any Apple Product can be checked on Apple’s Official Website with the serial key. We have already told how to check Serial Key. So you need to put the Serial key there, enter Captcha Code, and hit continue to check the warranty Status. If you have bought a used MacBook, and it’s not showing anything, you will have to verify the purchase date after logging in with Apple ID. If you don’t know the purchase date or it is not accepting, you have no other way except contacting Apple Support, and they will require purchase receipt to verify the purchase.
