I want to open in 32-bit mode

to watch movies in Firefox, I need tobe in 32-bit mode. How do I get there from here?

On a Mac, Firefox 4 is a 64 bit application.<br />
Not all plugins support 64 bit and if not then you need to start Firefox in 32 bit mode to use that plugin.
# Close Firefox
# Open the Applications folder in Finder
# Right click or control-click the Firefox.app icon
# Select "Get Info"
# Select or Deselect "Open in 32-bit mode"
# Close the "Firefox Info" window
# Restart Firefox

In MountainLion System Preferences, "iCloud", "Mail, Contacts, and Calenders", and "Software Update" all want to open in 32 bit mode. Security and Privacy won't open either.

As stated in the header,
iCloud
Mail, Contacts, and Calenders
Software Update
all want to open in 32 bit mode. Then when System Preferences quits and relaunches IN 32 bit mode, I get a dialog box saying "You can't open (pick one) preferences because it doesn't work on an Intel-based Mac." Moreover, Security and Privacy does the same thing only without the song and dance about quitting and reopening.
Whaaaaat???!!! I've never owned anything BUT an Intel Mac.
The "open in 32 bit mode" is not, and has never been checked in "Get Info"
I tried going to ~Library/Preferences and tossing all com.apple.system preferences files and rebooting. No joy.
It actually looks like some joker has included a bunch of PPC preference panes in my copy of MountainLion, except some of them are new to this OS.
My hardware is a mid 2010 13" MacBook Pro with4 gb of RAM, and a 500 gb hard drive, in three seperate partitions, running three Mac operating systems, one at a time. I have SnowLeopard in a small partition because I still have a few things that don't run in Lion/ML. Lion is still my main use machine in the largest partition, and when ML came out, I redistributed most of the unused space into a 3rd partition into which I did a clean install of ML in it's own partition so I could work through the growing pains without compromising my main computer. I'm glad I did it that way, but I DO want to get ML working properly, and I can't do that if I can't authorize third party software. Gatekeeper is currently in the way, and I can't get it to move.

I dunno, that doesn't make any sense to me.
I just shut down and rebooted into the SnowLeopard partition and took a peek at the preference panes. There are only 3 that run in 32 bit only. They are all 3rd party, and none of the prefpanes are non Intel. Like I said, I have never owned a PPC machine. Anyhow, SnowLeopard doesn't even have an iCloud prefpane, or a combined mail, contacts, and calenders prefpane, and the ML security and privacy prefpane is all new as well. The software update prefpane is Intel and 64 bit in both SnowLeopard and Lion.
As to the triple boot, unless I'm totally mistaken, what I have here is, in essence, 3 seperate descrete computers in one box. All using the same hardware. but one at a time. I wouldn't know how to get more than one running at the same time, without using a virtual machine, even if I wanted to. (Which I don't) I do sometimes transfer files from one to another using the shared folder, but other than that, they do not interact. How could ML system preferences be trying to launch prefpanes from a totally different machine?

Safari 5.1.4 breaks Google products and I want to open in 32-bit mode

As we all know, the new Safari update (5.1.4) breaks everything Google: Gmail, Docs, etc. There is a workaround, but it's NOT A SOLUTION: unchecking "open in 32-bit mode." Because when I do that, guess what? Other websites start breaking — like that of my chosen financial institution, for starters. So I'm going back to 5.1.1 until there's an update that fixes this problem.
Unless, that is, one of you has a brilliant idea that hasn't yet been mentioned in this forum.

Users&groups preferences pane wants to open in 32-bit mode

Crazy isn't it? The users&groups preferences pane says: "To use the "Users & Groups" preferences pane, System Preferences must quit and reopen (like with 32-bit pps). when I click ok, it says: "Preferences Error, Could not load Users & Groups preferences pane."

I had to reinstall Lion, just running the installer again, not a clean install and the problem was gone. Just give it a try (hopefully) nothing to lose...

ITunes will only open in 64 Bit Mode from Dock since Restore

I have only ONE big problem since doing a restore from my Time Machine backup-up for for Late 2009 iMac 27". For some reason I can only get iTunes to open in 64 bit mode if I put an icon on the dock???? It opens in 32 bit mode which is selected in the Get Info - Command+I if I open it from the Finder (which is my preference due to my many 32 bit Visualizers....) but if I put a shorcut icon on the dock REGARDLESS of what my settinigs are in the finder it Always opens in 64 bit mode and tells me my visualizers can not be loaded... Which I am well aware of!   What I don't understand is why this has just happened since reformating and restoring from a time machine backup???? Everything else... at this point appears to be working just fine.   BUT if I open iTunes from the dock... 64 bit mode no questions asked.... opened from Applications in the finder and it grabs my 32 bit mode Prefs?    This is really irritating. I have dumped caches, re-downloaded and installed iTunes.   Not sure what else to do???   Why is this ONLY happeningn if I put an iTunes link on the Dock?    Any help would be VERY MUCH appreciated.   Thanks.

Frank -
Here's the latest. I did the old standby of creating another Admin Account and the behaviour does not occur when logged into that account. So it appears that the restore somehow screwed up settings on my current account. I have indeed checked and there is no other copy of iTunes on my computer except for the DLoaded version of iTunes10.6 where I downloaded and tried to the re-install thing.
Of course still haven't heard back from Apple but I really wasn't expecting too this early. I guess that my next step is to transfer to the user/shared folder and change permissions on each and every folder/preference and file to the new Admin account... until I find out which setting is causing the problem.   To so this is a pain in 'arse' would be an understatement.
Also found out that Preferences has the same behavior as iTunes.   64 bit ALWAYS unless checked during that specific login and NOT started from the dock....   Strange though... both seem to hold the 32 bit (for the session) if run from 'recent', the Apple Menu, or the Finder???   As Alice would say "Curiouser and Curiouser"
My suggestion to ANYONE converting to LION (after this episode) is to back up and do a CLEAN install.   Obviously something from Leopard and Snow Leopard doesn't really like Lion that much.
I have been using computers since 1981 and Apples since OS 8 ... even had few dificulties with the OS X beta, but this one has me befuddled and somewhat irritated. I have thousands of dollars worth of software that I really don't want to have to re-install, re-register, but that may be the only viable option at this point.

HT201432 Open in 32-bit mode not in "Get Info"

I don't see the option to "Open in 32-bit mode" in my "Get Info" window. How do I get that checkbox to appear?

Looks like that particular pref. pane was written for PowerPC machines - you'd have to be running Snow Leopard or earlier for it to work at all
You may want to switch to something that is still supported, like Onyx

Aperture 3: Missing "Open in 32-bit mode" checkbox

If you installed Aperture 3 from a disc (vs. installing and registering through the Trial version), then if you do a "Get Info" on the Aperture 3 application, you'll notice that the "Open in 32-bit mode" checkbox is completely missing. To restore this missing 32-bit mode option, you need to start up your Mac in safe mode. To do that, hold down the shift key immediately after hearing the startup chime when you turn on the Mac. Here's Apple's help article on Safe Mode:
http://support.apple.com/kb/HT1455
Tip: In order for the shift key to be recognized during startup, the keyboard must be plugged directly into your Mac, NOT into a hub of any sort.
HOWEVER.... if your boot volume is a RAID array, you cannot boot into Safe Mode. So, how do you restore the missing 32-bit mode option? Easy... Download the Trial version of Aperture 3 from Apple's site:
http://www.apple.com/aperture/
After you get the E-mail and have downloaded the Trial version, move your current version of Aperture 3 out of the Applications folder (I just threw mine in the trash). Then run the installer for the Trial version and, when it's done, run the newly installed copy of Aperture 3. Surprise.... it won't even ask you if you want to register or act any different than the copy you moved out of the applications folder a few minutes before. All of your photos and settings will load as if nothing has changed. However, if you go to the new Aperture 3 copy and do a "Get Info", there is your missing "Open in 32-bit mode" checkbox!
My assumption is that the Trial version is a slightly NEWER version of Aperture vs. what is on the discs you buy. After all, Apple had to get the discs into production at least several weeks (if not a month or more) before they announced the release of Aperture 3. It makes sense that the downloadable Trial version could be a little newer.

Curiously I used the Retail boxed version of Aperture 3 on two machines. On the first one, my quad core pro, the 32 bit option is missing. On the second machine, my macbook pro laptop, the 32 bit option is there. The quad pro runs like a dog on aperture and the laptop runs like greased lightning. I wonder if the missing 32 bit option means something went wrong with the initial installation? I can tell you for sure that the 32 bit option in my case had nothing to do with trial vs retail box versions.

How do I get iTunes to open in 32-bit mode if I don't have a Mac, just a PC

I am trying to play a tv show on my PC that I bought on iTunes and it says I don't have the Quicktime, or something like that. So I downloaded a new Quicktime and it still says that. So I clicked on more info and it took me to an Apple page showing how to get iTunes to open in 32-bit mode from a Mac. I have a PC and I need to know how to get iTunes to run in 32-bit mode

You can use "History > Restore Previous Session" to get those page back.
Are you restarting this way?

Thank you for your response, Chris. But I'm afraid I have to disagree. There are native 64 bit versions of iTunes available for OSX and Windows.
In a 64 Bit Windows environment native 64 Bit Applications install the DLL's in a directory called "Program Files" and a directory called "Program Files (x86)" (32 Bit applications only use the ladder).
iTunes 9 is consistent with this behavior - and it identified itself to the system as a 64 bit application (meaning it's process appears without a "*32" tag on it).

Fallout75, good catch on the eXo plugin. To remove it, in the Finder click "Go" on the menu bar and pull down to "Go to Folder" and then type ~/Library/iTunes/iTunes Plug-ins
When that Finder window opens, you should see an "eXo" subdirectory. Just delete that "eXo" folder and iTunes should start without the error.

How do I get Firefox to open in 32-bit mode every time?

Often, I will navigate to a site or page within a site and I get the message "restart in 32-bit mode." This is frustrating because once restarted, I'm taken to my browser homepage. I then am required to re-navigate back to where I was when I got the message to restart, sometimes deep with a site.

I set firefox to open in 32-bit mode but it doesn't.

Netflix instant streaming still asks me to restart in 32-bit mode even tho I followed the instructions to ALWAYS start in 32-bit mode. I even reinstalled firefox. On Netflix when I click on the button to restart in 32-bit mode, it goes in a loop and just keeps asking for the 32-bit mode. This is a new problem, since in the past restarting in 32-bit mode always worked.

This is a known problem with Netflix and Microsoft Silverlight right now. You can try the following:
See if there is an update for Microsoft Silverlight.
After checking for updates, Go to Finder, then Applications. Right click on Firefox, then click "Get Info". Then check the box that says "open in 32-bit mode". Restart your PC, and test again. Does it work now?

'Open in 32-bit mode' checkbox missing...

I recently loaded MainStage 3, and went to disable the 'Open in 32-bit mode' option, so I could run it in 64-bit, but the checkbox does not exist. It is still there for the MainStage 2 icon, but not for the MainStage 3 icon. Has anyone had this experience and know a solution?

Thanks for your response. This is from page 13 of the MainStage 3 manual:
To open MainStage in 64-bit mode, Control-click the MainStage icon in the Applications folder, choose Get Info from the shortcut menu, then deselect the “Open in 32-bit mode” checkbox
I tried your suggestion, but can't find in Activity Monitor where it indicates the bit mode. Can you clarify? Thanks again.

Logic keeps opening in 64 bit mode...

I checked the "Open in 32-bit mode" box in the info, still Logic 9 keeps opening in 64 bit mode. Can anyone help?

Okay.. Suggestions...
1) Try running Logic Pro from inside the Applications folder and not from the dock....just in case the dock shortcut is having issues...
2) If you bought LP9 from the App Store, try downloading and reinstalling the App from the purchased tab in the Mac App Store App.
3) Download Batchmod from here....
http://www.lagentesoft.com/batchmod/
Run it and select your Logic Pro 9 application from it's file selector
Now set up Batchmod as shown in the following screenshot... (leave the owner setting as it is..mine says nigel.. yours will say something else) and press apply
Now try running in 64bit mode again....
