When I got a Macbook, I wondered what was an easy way to find out if I had a 32-bit or 64-bit computer. Well I found that one way is to use the terminal. So to access the terminal let’s do the following:
Click on the search icon near the top right, and type in terminal
Next, you should see a black box icon. If you do, press enter to initialize the terminal
Now we have a terminal in front of us. Type in “uname -a” without the quotes and press enter. You will be prensented with the following information.
If you see something like the above, “x86_x64” , this means that you have a 64-bit system. That’s it!
