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,
John Irvine

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 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 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/Shortcut_to_a_specific_profile
* 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 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.

Have been up for 2 days trying to have two versions of Firefox on the same machine because Princeton Review only supports 2.0 and my laptop upgraded me to 4.o can you please help?

When I try to access the interactive sites on Princeton Review I politely receive this message:
Your browser: Firefox 4.0 WinNT | JavaScript supported: Yes | screen size: 1366 X 768 | Flash Version Installed: 10.0 r42 | Supports AJAX:Yes | Click here to test connection speed
Attention:
'''This browser is not supported. '''Links to Start, Resume or Start Over any exams in iTest are disabled for this browser.
'''''We encourage you to use''''' Microsoft Internet Explorer 6.0 or higher or '''''Mozilla Firefox 1.5 or 2. '''''
''Use of your Online Student Center in Firefox 3.0 is not yet supported.''

IMO, you are better off installing - [http://sourceforge.net/projects/portableapps/files/Mozilla%20Firefox%2C%20P.E.%20Legacy/Mozilla%20Firefox%2C%20Portable%20Edition%202.0.0.20%20Repack/FirefoxPortableLegacy20_2.0.0.20_English.paf.exe/download Firefox Portable 2.0.0.20] - to your hard drive for the few web sites that are so out of date that they don't support newer versions of Firefox. That way you don't need to fool around with a separate Profile for 2.0.0.20, and there is less chance of a another version / Profile of Firefox getting "contaminated" by that old version or you losing private data if your get the Profiles switched.

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 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

iOS does not support multiple users like a desktop OS does.
You can use a web interface to your respective email accounts
to keep things separate; but there is no provision for otherwise
separating photos, media, etc.
If you wish, you can contact Apple to let them know of your desire:

HT2542 Can we have two separate itunes accounts using the same mac?

I am wanting to download music to my Thunderbolt smart phone (i know, no iphone yet, next upgrade) and I want to use itunes to do it. My partner has an itunes account and I thought I opened my own itunes account, but apparently I didn't. I don't like the same music and only want to download music I like to my phone. Can we just have one account and be able to download checked music from the itunes to multiple devices?

I'm confused
Can we have two separate itunes accounts using the same mac?
Can we just have one account and be able to download checked music from the itunes to multiple devices?
Do you want one or two?
By the way, and iTunes account is really the thing you use online to purchase music, not what you have on a computer. You have user accounts on a computer, and you have iTunes libraries or collections of media. You can have multiple user accounts on a computer. You can have a single or multiple user accounts use a single or multiple libraries. We need to know exactly what it is you have/want.

Can we have two different itunes accounts on the same mac?

Can we have two different itunes accounts on the same account? I am having trouble accessing mine from my sons.

Yes you can.
The fact you cannot access your son's library from your User account is intentional. User accounts on your Mac are nearly as separate from each other as your Macs are from anyone else's on the planet. To copy music from his account to yours, first copy it to the Shared folder, then log into your account and import the music. Then, you can erase it from Shared.
The Shared folder exists at /Users/Shared.

Can I have two apple TV boxes in the same home / wifi area, ar there any issues i should be aware of?

can I have two apple TV boxes in the same home / wifi area, are there any issues i should be aware of?

I was in a hotel a few month a ago. The hotel also had a portal page you have to sign in. Of course the ATV didn't a web browser and could not sign in to the portal and connect to the Internet, so your iTunes didn't work. (But your ATV should be connected to the router at that point already, just the portal won't open the port to pass through your ATV's traffic)
So what I did was to use AirVideo app on my iPad and AirVideo server on my Mac. Selected the movie on my iPad using the AirVideo app and then selected my AirPlay device on my iPad to AppleTV. Because this setup didn't require iTunes, so there was no need for a live Internet connection, and just a connection to the hotel router was enough. It was very easy.
(Of course, you can subsititude the iPad with an iPhone here too)
