Can i have two versions of OSX running on one computer

can i have two versions of OSX running on one computer?

Yes. The second one can be installed on an internal or external drive, but can't be one that the computer wouldn't be able to run if installed on the internal drive.

  • Can I have two versions of OSX running on same machine?

    Hi - since upgrading from Snow Leopard to Mountain Lion recently I have run into an unexpected problem (though I'm sure there would have been a warning that I missed). Some of my older applications, such as Adobe Creative Suite version 1, no longer run with the new OS. My plan is to install an additional hard drive in my Mac Pro (2009 dual Xeon version) and go back to my original software (Tiger) and install that on the new drive, then update to Snow Leopard with that software package. I will then, hopefully, be able to install CS1 on that drive.
    Am I likely to encounter any problems doing this? I will effectively have two different OSXs running on the same machine, albeit on differnt drives.
    Thank you in anticipation,

    The old "pop the DVD in, hold down Option or Command + C and just do a clean install on your new drive doesn't cut it?
    As for SL, it has to be retail, can't be the OEM gray disc from another Mac specific model.
    First, start up your computer from the Mac OS X Install DVD.
    Insert the Mac OS X Install DVD.  After it mounts, choose System Preferences from the Apple () menu.
    Choose Startup Disk from the View menu.
    Select the Mac OS X Install DVD as the startup disk and click Restart.

  • Can I have two versions of FF running side-by-side?

    I have moved on to FF5, but some of my add-ons are not supported. Is it possible to have FF5 and FF3.6 together, so I can revert to the older one when I need to use the old add-on? I like the interface of FF5, so would like to use it for most things

    Yes. The second one can be installed on an internal or external drive, but can't be one that the computer wouldn't be able to run if installed on the internal drive.

  • Am trying to connect my icloud to my outlook account.  Icloud says I have two versions of Outlook running.  I installed Outlook 2013 but Outlook 2010 is a trial version and I can't seem to be able to delete it without deleting all of Windows Office 2010

    You will have to remove one of the two versions, which one is your choice.

  • Can I have two versions of firefox? i.e. one for work and one for home use?

    Can I have two versions of firefox? i.e. one for work and one for home use. I use Windows xp
    I would like to start fresh with a new firefox for my work only so I can keep my work related bookmarks etc separate from my at home browsing.

    Yes - are you wanting to run 2 profiles on the same machine? See https://support.mozilla.com/en-US/kb/Managing-profiles on how to create a new profile. You then just choose which profile you want to use each time you open Firefox.

  • Can I have two versions of firefox at the same time?

    Hi,
    Probably a dumb question but can I have two versions of Firefox on my system at the same time?
    The reason is because of Add Ons that are not compatible with v4. I'd like to be able to close v4 when I need to use an Add On in v3.
    Thanks.

    You can install them both but there are a few steps to take.
    When you install Firefox 4 use the custom installation option and choose a different location to install Firefox.
    In order to use both versions, you need to create a new profile for Firefox 4 (Firefox stores user data in the profile). Using the same profile with different versions can cause problems. Once you create a new profile you can copy certain data such as bookmarks and passwords between them. You can also use Firefox Sync to keep the profiles synchronized. Finally, you will need to set up shortcuts to launch the correct profile for each version.
    The following links show how to do this:

    * http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox
    * https://addons.mozilla.org/firefox/addon/firefox-sync (only needed for Firefox 3.6, it is built into Firefox 4)

  • Can we have two instance of OHS running in a box

    Can we have two instance of OHS running in a box with single installation of OHS server.
    Something like running multiple apache instance with using different conf file for each.
    -Ram

    It is true that creating more than one instances of OHS out of one set of binaries (install) is NOT supported by Oracle. But is it possible if you don't care about what's supported by Oracle? You betcha! Yes it is possible (even in 10.1.2 and 10.1.3 OHS) to create and run more than one instances of OHS out of one install.
    This is basic Apache concept which Oracle does not disable. But I would again mention, this is something Oracle does not support. How would you achieve this? There is planty of information on internet, google can be your friend:
    http://lmgtfy.com/?q=run+multiple+apache+instances
    If you do this route, note that not just httpd.conf, you will also need to make another copy of dms.conf and ssl.conf. And if you want to have this another instance of OHS managed by opmnctl, you will also have to duplicate (with necessary changes) the section in opmn.conf about HTTP_Server too.
    Hope this helps.
    Thanks

  • Can i have two different face time accounts on one apple id

    Would like to have two different face time accounts, one on mac book pro and one on ipad.  Can I have two different face time accounts on one apple id?

    You simply need to have a separate e-mail identifier for each.  One e-mail address would be associated with the mac book, the other separate and distinctive e-mail address would be associated with the i pad.  This is done under one single apple id.  Essentialy, the e-mail addresses are the FaceTime calling numbers for each.

  • I have two versions of Lightroom installed on my computer, can I uninstall the older version?

    While looking at the "Programs and Features" folder on my Windows 7 computer I discovered that I have two versions of Adobe Lightroom installed on my system. One is Lightroom 5.2, installed on 9/19/2013, and the other is Adobe Photoshop Lightroom 5.5 64-bit, installed on 7/5/2014
      - Can I uninstall the older version?
      - Will uninstalling the older version cause any problems with the newer version?
      - If yes to either question, is there anything I need to do before doing the uninstall (i.e. deactivating, etc.)
    Any advice on how to correct this problem is gratefully appreciated.
    PS; I have the same issue with Muse CC. See: I have two versions of Muse CC installed on my computer, can I uninstall the older version?

    Jim,
    I thought it was odd that I had two versions of Lightroom installed as well. I have been able to track the issue back to an apparent "bug" in the Lightroom 5.2 update that installed a second version of Lightroom in addition to updating the existing version on my computers. At the time, I posted about it at Lightroom 5 installed twice on my laptop. While I never got an answer to my question, which was "Is this normal?" I did hear from others in the forum the experienced the same problem and had the same question. As time passed, later releases updated one of the two installations, but did not effect the second. Hence, two different versions of Lightroom 5 installed on the same computer.
    Uninstalling the older version solved the problem. Thanks

  • Can you have two different itunes account on the same computer

    how can you have 2 different itunes accounts on the same computer?

    You would need two seperate users on the computer. Then each library would be independent of each other. Or do you mean two seperate iTunes store accounts?

  • HT5148 can i have multiple versions of final cut on one machine

    I currently have Final Cut Pro X, but my video interface requires I use Final Cut Pro 7. Can I have both versions on one machine?

    You can use both the versions. But at times you will have to rename the application "MOTION" to open Final Cut Pro 7 & to use the option "Open a copy in Motion" in Final Cut Pro X!

    Can I have 2 different iTunes accounts on the one Mac computer

    Yes. If you mean Apple IDs, log in and out as needed. If you mean iTunes libraries, launch iTunes with the Shift key held down and choose or create one, or use separate Windows user accounts.

  • Can I have two versions of Safari on one machine?

    The question first, then the explanation for the question:  Can I have both Safari 5 and Safari 6 on my machine and run them at the same time?
    I hate Safari 6 & 7 because they combine the search and URL into one bar, which really annoys me.  It requires an extra step when I type in the direct URL I want, because instead of returning the URL, it goes to a search page, and then I have to click the site I want.  Annoying.   So I have not upgraded from Safari 5 on my iMac, which I use nearly all the time.  I have tried Firefox because it still has the search and URL boxes separate, but I also like the little orange arrow in Safari 5 that quickly takes me back to my original search when I've ended up on rabbit trails in my searching and I want to go back to where I was -- Firefox does not have this.  (I dislike Firefox in general, anyway.)
    However, now I'm finding that some websites are beginning to warn me that my browser (Safari 5) is too old and may not work properly.  Now I have found a site for which indeed that is true -- a site I regularly use for my job, and a company which says they will no longer offer support for issues on Safari 5.  One screen is split into two, and I could always scroll the two sides separately, but after an update to the site, now they will not scroll separately.  I have a MacBook Air, which I rarely use, and tested the same page on Safari 6 -- it works on Safari 6.  Thus, the company will refuse to help me and tell me to just update my browser.
    I really like Safari, EXCEPT for the new versions' combined search/URL bar, so I want to keep using Safari 5.  Thus, I want to know if I can have both Safari 5 and 6 on my machine at all, and if so, then I want to know if I can have them both open at the time, for example, if I give them different names (Safari 5 and Safari 6, rather than just Safari).
    This is for my iMac, which is running Lion 10.7.5

    >>I could not see this reply in Safari 5, neither by refreshing the page nor by clicking "Latest reply," which did nothing.
    That's a very common issue with the software that runs these discussions, and usually nothing to do with the browser. Pasting a single character reply, often reveals the missing item(s); as does viewing the thread without signing in first.
