32 or 64 bits: so you can know what your Mac's CPU is like — 2022

When buying a Mac, you can always ask yourself which processor to choose. The choice between 32 and 64 bits has always been hot, especially due to the limitations that have been imposed in recent years. In this article, we explain how to tell if your Mac is 64-bit or 32-bit.

What do the bits of a CPU mean?

The CPU is the brain of any computer and must know how to relate to the rest of the hardware components. Everyone will have come across when installing a program with the fact of having to install the 32 or 64 bit version. The bits are one of the main values ​​of any CPU and you have to know how to choose which one is best depending on the use that is going to be made of the equipment.

Know how many bits your Mac's CPU has

If at the time of making the purchase of your Mac you do not have knowledge about which processor you chose, at any time you can make the query in the system information. To do this you simply have to do the following steps:



  • In the toolbar click on the apple icon.
  • Then go to 'System Information'.
  • In the Hardware section you can view information about the processor.

Mac system information

Another possibility is to open the system terminal. Although it may seem that this is a part of the system that is focused solely on developers and is extremely complex, the truth is that it can offer a lot of information about the components of a computer. In the system terminal you simply have to enter the command:

At the moment a response will appear with information about the processor as well as the bits it has.

The differences between 64 and 32 bits

The main difference between the two processors undoubtedly lies in the number of values ​​it offers. For example, a 32-bit CPU offers 4,294,967,296 possible values ​​while a 64-bit CPU offers 18,446,744,073,709,551,616. When working, choosing between one and the other is fundamental with the amount of information that can be processed. With the 32 bits the processor is limited to using only 4 GB of RAM while the 64 bits use up to 16 GB of RAM.

All this data in the end leads to the key point: the ability to process information at the same time. If you are editing a video or working with a multitude of applications that require different calculations, you should keep in mind that 64 bits will work much better. The fact of processing much more information makes them more attractive to the general public, this being one of the causes that is causing 32 bits to become obsolete.

Right now the latest Macs that have come onto the market integrate these types of processor, leaving aside the 32-bit. This is vital when using the different applications that can be downloaded. If you want to get the best possible performance, try to install the 64-bit version whenever possible. This will get along much better with the processor and will allow it to be more efficient. To give you an idea, 64-bit processors are capable of processing 16 exabytes of cycles while 32-bit processors only support 4 bytes.

The problem that arises here is undoubtedly the optimization of the software to be able to make it compatible with 64 bits, something that is becoming more and more common.

macOS Catalina dropped 32-bit

As we have mentioned before, the 32 bits are becoming more and more obsolete. This forces developers to update their software to always be on an up-to-date 64-bit version. This is logical since the performance of the software adapted to the current circumstances must prevail at all times. Currently all the latest generation Macs have been released with a 64-bit processor. This is why Apple, in order to speed up the process, from macOS Catalina stopped providing service to 32-bit programs with the impossibility of executing them.
