Software :: Choose One When Both (32bit / 64bt) Available?
Sep 7, 2009
I know weird question, but a lot of software are compiled for both 32-bit and 64-bit, e.g.
Code: $ file /Applications/Safari.app/Contents/MacOS/Safari
/Applications/Safari.app/Contents/MacOS/Safari: Mach-O universal binary with 2 architectures
/Applications/Safari.app/Contents/MacOS/Safari (for architecture x86_64):Mach-O 64-bit executable x86_64
/Applications/Safari.app/Contents/MacOS/Safari (for architecture i386):Mach-O executable i386 And so Safari runs as 64-bit by default on my Mac.
If I want to run it as 32-bit (for whatever reason) is there a way to do it? Snow Leopard can run both 32-bit and 64-bit code but is there a way to choose one when they are both available?

My Windows XP partition is getting claustrophobic and it's about time I upgraded from an 8 year old OS.
Anyway, what's the easiest way to do this? I assume it'll have to be a clean install to go from XP to 7 and 32bit to 64bit.
I have a fair number of programs and several gigabytes of Steam games which is why I haven't done it yet.

How's it going everyone, I'm fairly new to Mac and I'm not very technical at all. I just purchased an i7 15" and I'm confused when it comes to 64bit vs 32bit. Does the computer automatically switch between the two or is there something you have to specifically do to run one or the other? For instance, I downloaded Handbrake last night, it asked if I wanted 64bit or 32bit? I have no clue? I bought a powerful machine, I want to make sure I utilize it.

McBook, 4 gig Ram 160 gig HD Running Snow Leopard 10.6.3 (Intel Core Duo)
I am running Creative Suite CS5 and noticed all plugins will not work, as CS5 works natively in 64 bit. I have tried opening in 32 bit and the beachball of slow goes on indefinitely and will not open in 32? I can still use plugins in CS4 then export product into CS5, but a bit of a long winded route...anyone else?

I am running an early 2008 Mac Pro: 4GB ram (only 3 running in XP) Dual Intel Quad-Core Xeon 2.8 GHz ATI Radeon HD 2600 256MB So over the last couple months, I've been getting some extremely bad and annoying freezing problems when playing Left 4 Dead on 32bit Windows XP Home Edition. The last sound played repeats over and over again with the screen freezing; this has lasted anywhere from 5 seconds - 40 seconds. My frame rate doesn't seem to be making a huge difference, its consistent at 45-60 fps when its on pretty simple settings:
Anti-Aliasing: None
Ansiotropic Filtering: Trilinear
Vertical Sync: Disabled
Multi-Core Rendering: Enabled
Resolution 1650x1050
Shader Detail: Medium
Effect Detail: High
Model/Texture Detail: Medium
Paged Pool Memory: High
At first I thought it might be my Graphics card over heating but tonight I tried it with the case open and a very powerful fan blowing air directly onto the card and the problem continued. PS. this hasn't happened with any other games but it doesn't run Crysis very well but thats obvious because well...its Crysis and even with it I have higher settings on. I've also cleared the computer of any spec of dust, just so you know.

This article gave me a little bit more understand and also made me feel better that either booting in 32bit or 64bit kernel will not make a huge difference due to hardware limitation.

I've successfully installed windows professional 32bit onto my mac computer with bootcamp. When I insert my OS10.5 Leopard cd's into the computer windows will not detect the CD's. These are original CD's after trying to get it to work for a few mins I came up with an idea. I downloaded the 2.1 mac drivers from apple @ [URL]. I then burned the drivers onto a cd and then rebooted into windows. After copying the drivers from the cd to my harddrive, I tried to install the drivers that I had downloaded but nothing happens. I can see in the taskmanager that the BCUpdateXP.exe runs for a few seconds then does nothing. The mac is an iMac 8.1, intel core 2 duo, 2.66ghz, 2gb ram. The leopard cd's work when running the mac under Mac OSx 10.5.8 which would mean the cd's should be fine.

I was messing around with Audio Hijack and it was working just fine. But now it seems iTunes always starts in 32-bit mode (even without audio hijack running). Also it seems to take quite a while to open the app. If I log in as root (or via a Terminal) I can open iTunes just fine, 64-bit and it opens instantly. Also when I log out OS X hangs a while on the screen you get when he's logging you out (the blue-ish screen).

Im about to recieve my MPro w/8800, and plan to have a dedicated HD for Windows in bootcamp. Windows will be used exclusively for gaming (real-time-strategy games mostly, if this matters).
I am keen on going into Vista, trading a bit of XP performance/stability towards full/hassel-free compatibility with Directx10 and future games, but have no clue whether it makes sense or not to go with the 64 bit version.
I understand this version allows to use much more RAM (which i will have installed on the MPro), AND more than a single core used.
What i dont have a clue about is wether the 64bit version is compatible with all (or grand majority) of games, whether they do actually take advantages of the 64 bit possibility (which im not sure at all, as i believe you have to program it to do so), etc.

I have an Late 2008 Macbook pro unibody, 4gb, 320gb 7200rpm. I installed the bootcamp drivers off the leopard CD that came with the mac and all was good! I have since taken it to Australia for a holiday and need to reinstall bootcamp but left the Leopard CD back in the UK. Stupidly, the 2.1 bootcamp drivers on Apples site don't support the Unibody mac! Can anyone please direct me to where I can download the Drivers (for 32bit XP home SP2) for the Unibody Macbook pro? The exact ones that are on the Leopard CD that came with the new Macbook Pro?

Recenly got myself a Macbook Pro and installed Vista 32bit on it. Runs great (although the fans start blowing quickly and hard in Vista compared to OsX) but I do have one problem: when I play games (HL2, Fallout3...) the games tend to crash after a few minutes (the application itself, not the laptop)
I tried installing (modded) drivers, updating all I can update but the problem remains. Only thing I have not tried is re-installing Windows, but not sure if that would even solve my problem.
Temperatures measured with HWMonitor seemed pretty normal to me (cpu max 62�C, gpu around 82�C).

I'm not sure which forum this belongs in, but given that its really a vmware question, I'm thinking that applications is the best fit.
Anyways, if I decide to take the plunge and get windows 7, it will be for the express purpose of running within vmware. I have zero interest in running it in bootcamp (I use fedora and boot into that) so basically which version of win7 would provide the best performance. The 32bit or 64bit flavor

Because Adobe hasn't the Ballz to release a 64-bit version of Flash Player to all platforms, any application that runs in 64-bit and utilizes Flash will have to use the WebKitPluginHost to cater to Adobe's.32-bitness. This means Dashboard now consumes MUCH more resources than in Leopard. I made a Pandora Webclip back in 2007 and it has been FLAWLESS over the years, until Snow Leopard. My only hangup is, Dashboard only opens in 32-bit mode during the first uptime that I have checked "Open in 32-bit Mode". After a restart, it opens in 64-bit mode, EVEN while the same option is checked.

I've recently bought a new iMac and would like to migrate my stuff from my early 2006 iMac (first intel mac, 32 bit). There are several ways of doing this, but I'd like to achieve:
1) Identical copy
2) Defragmented drive (previously it was getting very slow)
As I know from using Windows, you cannot simply create an image from one PC and move to another, because of differences in the kernel. The new PC may never boot. I am moving from 32bit to 64bit, so that would be quite a change. Also, should I use the migration assistant, or boot from recovery disc and recover from my time machine backup? Will the latter not result in a more identical system? And, is that desirable? My old iMac has all updates installed, so it should be the same as the new system.

Set for release this fall, Microsoft's forthcoming Office for Mac 2011 will only be available as a 32-bit product because it hasn't completely transitioned to Cocoa for Mac OS X. Microsoft's Mac OS X development team, MacBU, updated its official website this week to note that its members are at WWDC 2010 this week, taking part in Apple's developer sessions. The team revealed that their focus has been to increase compatibility between the Windows and Mac versions of Office, which means a 64-bit option on the Mac won't happen this year. "Our work to increase compatibility means we haven't completed the transition of moving the entire user interface over to Cocoa yet," Jake Hoelter, product unit manager with MacBU wrote. "And because Apple's frameworks require us to complete the move to Cocoa before we can build a 64-bit version, Office 2011 will be 32-bit only." Elements of the newest Office for Mac, including the ribbon user interface, are built on Cocoa, the development layer of Mac OS X.
And the all-new version of Outlook has been built from the ground up with Cocoa for the Mac. Hoelter said that Office for Mac 2011 will still look and feel "great," Cocoa or not. He said the biggest advantage in having a 64-bit application is the larger memory capacity. "Most users with typical or even larger-than-average document content will not notice a difference in performance," he said. "Where 64-bit can make a difference for people working with huge amounts of data, such as those creating very large Excel files with data in millions of cells, or PowerPoint presentations with thousands of high resolution images." He also noted that the Windows Office Engineering team has recommended that most people buying Office for Windows stick with the 32-bit version, even though it will also be available in 64-bit. The team said the 32-bit version in Windows offers the best compatibility. Hoelter said the MacBU team supports Cocoa because it makes it easier for them to give applications the look and feel that Mac users want.
In the future, he said, the team plans to go further with Cocoa. "Meanwhile," he said, "I think customers are going to be really happy with the improvements in compatibility, collaboration, and user experience we're bringing in Office 2011." The new version of Office for Mac promises greater feature parity with its Windows version, including improved support for Exchange and reincorporated support for Visual Basic for Applications. It also has a similar look to Office 2010 for Windows, adding the ribbon interface found in previous Windows versions. Office for Mac 2011 will also add co-authoring tools to allow multiple users the ability to work on files from Word, PowerPoint or Excel from different locations. Microsoft Web Apps can also be accessed, allowing users to share Office documents from any machine with an Internet connection. And Microsoft has said the new ribbon interface gives "the best of both worlds" by using the classic Mac menu and Standard Toolbar.[View this article at AppleInsider]

I have Bootcamp 3.1 and Windows Vista Home 32bit is fully up to date.
The audio on my Mac Pro 2008 will play out of the front speaker but will not through my Klipsch 2.1 system. I checked and rechecked to make sure I have the audio cord plugged into Audio Out on the back of the Mac. When using OSX the audio plays just fine through my 2.1 system.
Any ideas on what I can do to troubleshoot the issue?

The installer from this DVD will not launch on my Mac Mini. The store I bought it from won't let me return it so I'm stuck with it. Is there anything I can do to get this damn thing to work? I get a black screen after it huffs and puffs and then dies.

It appears that for whatever reason, the kernel on my Mac is 32bit/i386, but the architecture is 64bit:
Darwin system.local 11.3.0 Darwin Kernel Version 11.3.0: Thu Jan 12 18:48:32 PST 2012; root:xnu-1699.24.23~1/RELEASE_I386 i386
Though the kernel itself is a universal binary:
mach_kernel: Mach-O universal binary with 2 architectures
mach_kernel (for architecture x86_64): Mach-O 64-bit executable x86_64
mach_kernel (for architecture i386): Mach-O executable i386
Info:
Mac Pro, Mac OS X (10.7)

I've had my iMac for just under a week now, and I wanted to play some games, so I did a Time Machine backup, and ran BootCamp. Vista install disk wouldnt work, so I used my copy of the Windows 7 RC1 32bit. That worked fine, its installed and working just fine, but when I went to check what it would show under "System" in the control panel, it shows my memory as 4.00GB and says 2.73GB useable. Is this normal? I know that 32 bit cuts off memory at around 3.23GB, and I was under the impression with Windows 7 and Vista SP1 the limitation was supposed to be moved to 4GB. Is this something I should be worried about? Also, I get some really bad lag spikes on Windows.

So I'm trying to manually update Graphics driver in Win7 32bit for the Macbook pro 13" mid 2010 version with the Nvidia 320M video card. I download and get this driver: 257.21_notebook_winvista_win7_32bit_international_whql
But it doesn't help me at all, says it can't find any drivers compatible with my hardware, even though I selected all the right menus for my card. I'm trying to play this one game, but it's bugged and I figure if I install a driver that's 5 months more recent it might help.

I just got a refurbished MacBook Air from apple. What they didn't tell me when I ordered was that it was Rev C. I got the 13 with the 2.13 processor. It was $200 less than the Rev D. Question is should I send it back and get Rev D with 1.86 processor for $200 or keep Rev C. Biggest difference I see is SD card slot.

Well I have some money from a research grant to buy a new laptop as my trusty old Dell Latitude D610 is really starting to give up the ghost. I decided after I bought my Pro that I really didn't want to go back to crappy PC laptops, and I'm really psyched after the notebook update to get one of the new models, but I really don't know which.
Anyway, I went down to the Apple Store today to play with new the new MBs/MBPs. Everything was going pretty well really - until I realised how bloody heavy and wide the damn thing is! It feels quite a bit heavier than my Dell even though it's only 250g more. I virtually always have my laptop with me, and the more I think about it, the more the weight factor might become a deal-breaker for me. Actually, not having my laptop in the bag for the first time in a while has really made me realise how heavy the damn thing is - I'm not sure I want to put up with that for the next couple of years.
If I'm honest, the Air is really what I want. But I'm not sure how well it will cope with my daily routine, which generally has some of the following:
Running scientific programming applications - post-processing data, Fourier transforming it, etc. I've been really encouraged by the two-page thread on these forums saying that MBA is capable of doing this sort of thing. The 6MB L2 cache sounds really good.Casual gaming is something I've not been able to do with my D610, and it'd be nice if it were capable of running some lower end games (for example CS:S, HL2) even at reduced resolution. I've heard the 9400M should be good enough for this, but maybe I'll wait on that. Clearly the MBP is more cut out for this.
As you can see from my sig, I like photography quite a bit. Most of my photo work is done on the Mac Pro, but often I'll find myself out and about and would like to download the photos; it would be nice to be able to run Lightroom.
I listen to a heck of a lot of music, but I don't think there will be a problem here.
I'm virtually always online, web browsing and e-mail etc but again I don't think this will be a problem.
I think I can live with only the single USB port, and the lack of a DVD drive doesn't bother me greatly. Ethernet is a bit of a pain - ideally I'd like gigabit ethernet, so I'd need to give this some thought. Nothing I have has a Firewire port on it. Generally the only thing that gets plugged into my laptop is the iPhone and my headphones, so I think I'm good on that front.
The MB is also a sensible option, with most of the pros of the Air without the drawbacks. Weight is slightly less than my existing laptop, and I guess it's probably just as portable. It also has the option of a higher 2.4GHz processor, and more in terms of expandability. Not sure whether I really want this or not, though.
