From the system report, scroll down to Software in the sidebar, then select Applications. When you select an individual application, you will see a field titled bit Intel. If you're using macOS Mojave, select Legacy Software in the sidebar to see all applications that have not been updated to use bit processes.

Can I keep using my bit apps? But users didn't get the message until April, when Apple published a support document and with the macOS This app needs to be updated by its developer to improve compatibility. To see a list of a Mac's existing bit applications, users should click "About This Mac" from the Apple menu, then click the button marked "System Report. From there, scroll down to the "Software" section in the left-hand pane, then click on "Applications.
Those bit applications will each be marked "No" in the Bit Intel column. The Mac will list every bit application in the System Report. They're the ones marked "No" in the right-most column.
What Apple's 32-bit app phase-out on Mojave means to you
The on-screen bit alerts, which run only once for each eligible application, are less about informing users of an impending change than another way to prod developers to get cracking at bit. That was clear from a message Apple pitched to developers a day before it activated the April warnings, reminding them that it was about to do so, and implying that they should prepare for an uptick in customer queries. Apple suggested that users "check with the software developer to see if bit versions of your favorite titles are available.
A cruise through a bit app developer's website will be worth the while, as will be visits to the firm's support section and, if necessary, an email to the developer's support team asking about bit availability - as well as a timeline, if that hasn't yet happened. In corporate settings, this kind of investigation would typically be handled by the IT staff. But in smaller shops, workers may be responsible for uncovering app migrations to bit.
A common resource, like a shared document listing bit availability, will make it easier to decentralize the work and circulate the results. In general terms, the larger the developer, the more likely it has already made the move to bit. Microsoft, for example, launched bit versions of its Office apps - Word, Outlook, Excel and PowerPoint - in August , automatically updating the suite's programs.
Cristian Ciupitu 4. Greg Cain Greg Cain 1, 1 13 This is the best answer in my opinion. And a suggestion: 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, 12 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.
Apple's 64-bit push began last year
According to another knowledge base article , MacBook Pro from early through mid support the bit kernel, but do not use it by default. Another option is to use sysctl in a shell: 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. Thu Aug 23 Sridhar-Sarnobat 7.

Pav Pav 91 1 1. 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.

64 bit - How to check whether my Intel-based Mac is bit or bit - Ask Different
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 original question was about if the OS is 32 or 64 bit, not the supported architectures of the processor: The kernel is not the OS, and the kernel's mode is irrelevant to what the asker actually wants to know: 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.
