How do I determine if I have a 32-bit or 64-bit system?


In this article, we will explain how to determine if your system is a 32-Bit or 64-Bit system. Please select the option that is applicable to your operating system:

To determine the system type for macOS

  1. Open the Apple menu and choose About This Mac.

  2. Click the System Report button. If you do not see this button, click More Info, then scroll down and click the System Report button.

  3. On the Hardware panel, locate the Processor Name. If you're using a Mac with an M1 or M2 chip, a Processor Name will not be listed; instead, you will see a Model Number and Chip. All M1 and M2 Macs use 64-bit architecture.
