How to know if mac platform is macOSx64 or macOSaarch64

Question

I am trying to download JDK from Amazon Corretto https://docs.aws.amazon.com/corretto/latest/corretto-11-ug/downloads-list.html. There are 2 download links for macOS (macOSx64 or macOSaarch64) but I am not sure which one should be downloaded. I am using macOS Monterey Version 12.0.1

Usually, menubar > about this mac should show you everything needed – Dissenter

You need to provide more information on your device. "macOSaarch64" is an Arm processor, whereas "macOSx64" will be an intel processor – Classless

Did you try to google this? – Sanderlin

I did, but I do not find a clear answer. – Roup

Thanks @BasilBourque I dont remember the context around asking the OP to google this. But, yea, you are correct. – Sanderlin

Answer 1

You can run the following command to get that

uname -a

Having x64 in there might give you a hint.

➜ ~ uname -a //Darwin MacBook-Pro-2.local 23.4.0 Darwin Kernel Version 23.4.0: Fri Mar 15 00:10:42 PDT 2024; root:xnu-10063.101.17~1/RELEASE_ARM64_T6000 arm64 – Judicature

uname -m is a better solution if you want to use it in a script as it directly gives you the architecture instead of you needing to parse it from a long string – Ionosphere

About This Mac

1. From the Apple icon menu, choose About This Mac.

2. Look for the item Chip.

3. If that item says M1 or M2 or M3, then you have a Mac with Apple Silicon based on the ARM AArch64 architecture. Download your macOSaarch64 option.

4. If that item says Intel, then you have the x64 chip architecture. Download your macOSx64 option.

See Apple support page, Mac computers with Apple silicon.

Bonus tip: SDKMAN! is a clever utility that makes it quite easy to find, download, install, and uninstall a JDK.

SDKMAN! only lists JDK products from vendors who volunteer their product info. As I recall, that includes Amazon and their Corretto offerings.

Answer 3

If your computer is one of the new M1 or M2 chip computers, then you would use macOSaarch64.

If your computer is an older Intel chip computer, then you would use macOSx64.

You can tell which you have by going to Apple menu and then selecting 'About This Mac' and Look for 'Processor' or 'Chip' in the About This Mac window.
