Eclipse 32 vs 64 bit mac
How can I tell the 32 or 64 bit capabilities of my Mac? What version of the OS are you running? When was your MacBook Pro built? It's quite simple. Go to the Apple logo and select "About this Mac. If it says Core 2 Duo, then it is 64bit ignore the 32bit kernel issue, it will run 64bit software just fine. Physically, if your MBP has a black keyboard, it is absolutely 64bit. The original MBPs had a silver keyboard and the 32bit units were all but replaced in early So if you purchased your model even in the later course of , then it is a Mac capable of running 64bit.
Also, if you are running Lion, then you are 64bit as Lion does not run on 32bit Macs. Paul Lefebvre Paul Lefebvre 2 2 silver badges 5 5 bronze badges. System Profiler isn't installed on my machine—or Spotlight can't find it—so this answer won't work for everyone.
What is your machine and OS? The name was changed to "System Information" a while ago it's in Utilities folder. I did find the System Information app. It would be good to update the answer for the benefit of others. Unfortunately, I couldn't find the "bit Kernel and Extensions" item in the Software section of the System Information app. I'm on v If you are using I have Mac OS X Cristian Ciupitu 4 4 bronze badges.

This is the best answer in my opinion. Basically if you have anything newer than an MacBook you have a 64 bit processor and OS… Here is the cheat table. Nate Bird Nate Bird 1, 13 13 silver badges 22 22 bronze badges. This does't tell the full story but it's a start. That is true.

The line is technically blurry because the kernel may only be running in 32 bit mode but everything else is 64 bit. According to another knowledge base article , MacBook Pro from early through mid support the bit kernel, but do not use it by default. What Is Bit Computing? This is why most people focus on the address space for a specific program rather than whether the hardware is "bit" or how much of it is "bit" It really doesn't matter until you get to a more specific question. The full output looks something like this: Darwin Macbook-Air.

While this will work, there are several far simpler options that don't require a novice user to enter Terminal. Also this only gives you the arch of the kernel. On a Core2Duo a 64 bit CPU you still only run a 32bit kernel if the bootrom of that machine is not 64bit clean. You can still and should use a 64bit Eclipse on that machine. But the good thing about this solution is it's cross-platform though yes I know this is the Apple Stackexchange area.

Uh, no. My processor is bit and i have lots of bit processes running, though, so this seems to only tell you what the kernel type is. What David said - this only tells you what kernel is running. Like David, I'm using a bit kernel because I need a kext that requires it, but I can run bit user processes with no problem. The kernel's mode doesn't really matter to userland; OS X will happily run bit processes under a bit kernel or vice versa. The kernel is not the OS, and the kernel's mode is irrelevant to what the asker actually wants to know: which version of Eclipse is appropriate?
I like bisko's answer because it helped me to find a way to tell for sure what I am currently running - bit or bit.

Without actually starting VMWare, it is nice to know which mode I'm currently running. It seems some of my other applications run better also in bit mode. Thanks for all the different angles of answers to the main question. Gordon Davisson Gordon Davisson Run in Terminal: sysctl hw. Running arch gives "i". In the mean time, sysctl hw. Then which is it? I'm running OSX I say go with the bit Cocoa version unless you want to use Java 6. The bit version will use less memory, and because the bit 1.
The reason there are multiple versions is due to the SWT's and Eclipse's for that matter philosophy of one architecture and one windowing system per application. Depends on what you're using it for.

I wrote an article about it: blog. The version of Java used to run Eclipse and the version of Java used for your program does not have to be the same. Unless you have enourmeous, gigantic programs just use the bit Carbon version.

It is the oldest and most mature. Tiger is older and more mature than Leopard and Snow Leopard, yet, people upgrade. It is also stable and well debugged get the SR1. Tiger is older than Leopard, but not more mature. Use Cocoa 64bit, you most likely have a 64 bit processor unless you know you don't. Carbon is just the old graphical API, it was replaced by Cocoa.
