Does Safari still need to be opened in 32-bit mode?

Wondering if I can switch it to 64-bit?

Hi James
you certainly can use it in 64 bit mode - there was never any general need to do otherwise, despite rather a lot of claims to the contrary, which persist even now.
Some plug-ins/add-ons don't work in 64 bit, most do, Flash does -  so unless you find a problem, switch to 64 bit, which is only available on Snow Leopard & on Core 2 Duo or later cpu's.

  • "Open in 32-bit mode" not available

    Two iMacs, (2.66GHz & 1.83GHz), both running 10.6.2. The GET INFO window for SAFARI on the older iMac does not show the checkbox with "Open in 32-bit mode" beside it - the newer iMac does. Other noticeable difference is "Open using Rosetta" is 'active' (available {but not selected]) on the older iMac (Rosetta is installed), whereas it is 'greyed out' on the newer machine (where "Open in 32-bit mode" is available).
    It 'appears' as if, on the miscreant iMac, that Safari IS running in the 32 bit mode whereas iPassword 2 is working fine in Safari - that version of 1Password isn't suppose to work in the 64 bit mode. If this is the case, how do I get SAFARI back to the 64 bit mode.
    Thanks

    HI Jim,
    Open your Activity Monitor application. (Applications/Utiities) and select My Processes from the pop up menu.
    You can view which apps run in 32 or 64-bit mode under Kind on the right.
    If you don't run Safari in 32 bit mode, Safari is likely to crash and freeze. So your iPassword 3rd party app should be ok.

  • 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....

  • Why does Safari still accept cookies, even when I put Block Cookies "Always"

    Why does Safari still accept cookies, even when I put Block Cookies "Always",? There are always a list of every website with cookies. Is that just a record of what could've been accepted or its a bogus feature that still accepts regardless of what feature is on?

    Apple has rolled over users since OS X 10.6.8 when this issue first appeared.
    If you want a browser that actually CARES about it's users, then install Firefox, it's the only one that does.

  • 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.
    <Edited by Host>

    go here:

  • TS3934 Logic does not open in 32 bit mode

    Macbook 10.8.5 running Logic Pro 9.18 
    OK ... I have tried the following.
    Logic Pro highlight / get info and ticking "open in 32 bit mode"  it shows as ticked
    deleting user audio unit caches
    running mac in 32 bit kernel mode
    reinstalling logic Pro 
    NOTHING ..... Logic opens in 64 bit ..... I have loads of plugins that don't run in 64 bit ... i'm waiting until everybody is singing from the same hymnbook.
    HELP PLEASE !!!!!!!

    You are most likely opening some other copy of Logic that you (still) have somewhere else. There is no known issue with Logic Pro 9 not opening in 32 bit mode on any compatible Mac OS X system. As Jazz already said.

  • 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?
    # Close Firefox
    # Open the Applications folder in Finder
    # Right click or control-click the Firefox.app icon
    # Select "Get Info"
    # Select "Open in 32-bit mode"
    # Close the "Firefox Info" window
    # Restart Firefox

  • 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.

  • 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?

  • 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.

  • A site I use every day told me today that it would only open in 32-bit mode.  I cannot change this in system preferencees as suggested.  Could anyone explain to me why suddenly, and how to change this? (MacBook Pro 10.6.8) Thanks!

    Hi.  I am in need of advice - and am not very IT savvy!  I have a MacBook Pro 10.6.8 OS.  A site I use every day told me today it would only open in 32-bit mode.  I researched and found some advice on how to choose 32-bit mode in system preferences.  I do not have that box to click in system preferences.  Can anyone tell me as to why suddenly this has happened, and any suggestions on how to go back to 32-bit mode would be great!  I did try restarting holding down the 3 & 2 keys as suggested too.  No luck.  Thanks for any help. 

    Does the site use 32-bit mode Java? If that's the case, you should have both 32 and 64-bit enabled though Java Preferences in your Utilities folder:
    See what you have enabled...

  • 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

  • Open in 32-bit mode finder flag doesn't always work on all applications

    When I set "open in 32-bit mode" flag in Finder (get info window) for Quartz Composer it is respected on normal application launching but if I restart (with updates, ex.) the computer it launches it in "normal" 64-bit mode. (Normal application launching would be clicking the icon)
    This doesn't happen with other applications (at least with one other; non Apple) which have the same flag setted, on the same circunstance.
    This non Apple application that works as expected already had the flag setted on installation (it didn't require manual setting, I mean).
    Thanks,
