Multiple user audio

Heres the story.
I log into my account, start up rosetta stone , do audio test via the USB headset all is fine.
(Preferences are set to default internal mic and speakers. )
I close rosetta stone.
I log into my sons account, boot Rosetta stone, try audio test as above, fails.
(Preferences are set to default internal mic and spekaers.)
I choose USB device for input in the preferences, it is alive I can see activity.
Try rosetta stone again still fail.
I flip back to my account and log out.
I come back to my sons account and try the Rosetta stone audio test all is fine !!!
I log into my account again, launch Rosetta Stone, try the audio test, fail
Is this OS X Lion not sharing USB audio devices across users?
Shas-O

Yep. I get the same issue. In order for Rosetta Stone(RS) to work for a user, that user must start RS when no other user is logged in. Otherwise, it will not properly detect the audio input (in my case USB). I mean, it will detect the devices but it will not capture the audio input.
But once you start RS as described above, others can login and it works fine for me.
So I planning on simply leaving RS running the whole time on one account and do all our training from there.

[solved] Pulseaudio, multiple users, audio group?

Hello!
I'm trying to get pulseaudio working for multiple users. According to the pulseaudio documentation, no user should be in the audio group which should theoretically make it work. I think I've also seen that information in a file distributed with the official archlinux package somewhere... But without users in that group, I'm not getting any sound at all.
$ ls -l /dev/snd

That should - according to pusleaudio docu - mean, that HAL and/or polkit will be handling user switching & stuff but it can be overridden by the audio group...? Well it does not seem to be working that way.
So... where do I start? Can't find any relevant information... everything on the subject seems to be either obsolete or just not working...
Thanks!

I log into a tty and let xfce handle the rest. Which means the first user's X gets started by startxfce4, the second user by xinit + xfce4-session (because I don't know how to make startxfce4 use another display).
I thought those two should handle everything correctly? I took a look at the sources a while back - looked pretty complicated to me: the scripts were checking for the status of needed stuff + trying to launch everything correctly.
But I'll try it manually again next time I get to it to make sure, that ck-launch-stuff is really handled correctly. Thanks for the hint!

Multiple Users - 1 Library

Is there a way that 5 different people can use iTunes on the same computer without having to share and modify the same library? Ideally, what I would like to do is set up different profiles for me, my wife, my daughter, and my two sons so that each of us can have a different library on the same computer....
Thanks,
Coach

While the original request was for a way to make multiple libraries there is another approach to multiple users that is worth considering.
You can keep all the music in one library and make use of playlists to control which music goes on to each iPod. You can create regular playlists into which you drag different selections of music however I prefer to make use of the grouping field and create smart playlists based on the content of this field.
e.g.
"Alice's Tracks" is "Grouping contains Alice" + "Kind contains audio"
"Bob's Videos" is "Grouping contains Bob" + "Kind does not contain audio"
Tracks that both Alice & Bob want on their iPods have the grouping set to "Alice/Bob"
etc.
I currently manage four iPods using this system, each getting a different selection to suit their tastes and the capacity of their iPod. An advantage of using the grouping field is that it is stored in file tags (for audio files anyway) so that it is relatively easy to recreate the playlists should the iTunes library get trashed. Also useful if you move files about manually as playlist membership is preserved when you delete & re-import the tracks.

Can quicktime play an video track with multiple alternate audio tracks?

Hi,
If I have a video track with multiple alternate audio tracks (say different languages), can a user select the audio track of his choice and play in Quick time?
Thanks,
Apurva

Does quick time/ safari have this capability?
QT (i.e., the QT structure embeded in current Mac OS/device IOS versions) has the ability to switch between alternative audio tracks assuming the file is properly encoded and the compression format is supported. QT 7, QT X, iTunes, and similar app player GUIs can switch between such tracks during playback but the QT plug-in cannot. In a similar manner, devices like TV can switch between such tracks but an iPhone cannot just as an iPhone can select "Chapters" but the QT browser plug-in cannot but an iPhone file programmed with both chapters and alternate audio tracks can be played back through a TV device and access both chapters and alternative audio tracks.
What I want to use is one video track with alternate audio tracks in a set level manifest and play this using HTTP Live streaming. I'm using the manifest mentioned here :
http://tools.ietf.org/html/draft-pantos-http-live-streaming-07#section-8.7
Since I do not use playlists, I am not familiar with the approach in your example. If I want alternate audio and/or video tracks, I create standalone video files with these features built in. Nor do I use RTSP if that is what you mean by "live streaming" of content. If I want to "stream" the content, I use "Fast Start" files programmed to open in the QT player app which supports these features or create reference or QT Media Link files that do the same thing.
As you mentioned, Safari on my iPhone is playing the default/first alternate audio track mentioned but not giving an option to switch tracks.
Neither Safari nor the Video app GUIs on your iPhone have a built in switching option. The only way to switch to alternate audio tracks is to do so with QT 7 Pro or possibly iTunes before loading or streaming the video file. (Am still speaking about a standalone file here and not a programmed playlist/RTSP switch.)
However Quick time on my Mac machine only plays the audio with the the video stream and not the alternate audio track.
The QT player app GUI only switches between tracks that are stored as part of the standalone file. Basically, QT files may contain up to 99 individual data tracks. In alternative audio videos, multiple audio tracks are added to the file by an editor like QT 7 Pro but only one track is designated as "active." All other tracks are designated as "inactive." The QT player GUI allows the viewer to select which audio track he or she wants to hear and then turns off the current audio track and turns on the selected audio track. Otherwise all active tracks would play simultaneously.
Is there a way to switch tracks on my iPhone on Safari?
As previously noted, the default track can be manually changed by QT 7 Pro or, I believe, iTunes (used to have this capability) before actually loading or streaming content.
Does quicktime have this capability?
As far as I know, only with regard to stand alone files programmed with multiple alternate tracks. I am not a HTML, HTML5, or Java programmer so I assume there may be web alternatives here but they would be beyond the scope of my expertise.
Do you know any free player that can do this?
Again, I don't use either playlists or RTSP so I've never had a need to look for/use alternative players that might meet your needs. I simply find it easier to build files that work correctly in current player app/device GUIs already having these capabilities.
Or the very last option, can I build a player to do this? If yes can you suggest where/how I start?
Once again, I assume this might be possible but not part of my experience since, for my part, easier work flows are available.

How can multiple users use the same Creative Cloud Individual on one single-machine?

We have one shared graphics workstation, which is infrequently in use by different people - therefore we bought a single-workstation license (which we were referred to "Creative Cloud Individual"). In the FAQs it says it installs locally, but whenever a user different from the installing adminstrator logs in, he is forced to use the trial.
Is there a way to make the local installation usable on that single machine for multiple users?
Thanks in advance for your reply

Serenatasystems do the other users not have administrator access? What happens if they sign in using the Adobe ID tied to your Creative Cloud subscription? Do your Adobe Creative applications then exit trial mode?

Multiple users in household, how do I simply sign out of an account and not delete the account?

I just got an iPad and am still figuring out its quirks. One thing that is completely frustrating me is that I am being told that I have to delete accounts instead of simply being able to sign out? I don't get it? For instance the Gmail app lets you switch between accounts but both are always signed in. Same with iCloud and Appleid's. I don't get it? I have multiple users at my house that use the same apps but we can't sign in and out as our respective selves? Is this an Apple thing? I haven't used Apple products since the mid 90's so I could just be out of the loop? Not being able to Sign in and out doesn't seem very logical to me so it makes me think that I must be missing a step because why on Earth would you not have that function? Help me understand. Please and thank you.

You are not going to like the answer, but no you cannot sign out of email accounts on the iPad. The iPad was originally designed to be a single user device that was to be used in conjunction with one's own iTunes library. That was back in 2010 when the first iPad was released. many things about the way you can use an iPad have changed, but it still designed to be a single user device.
Anybody can check email in a web browser on the iPad, just like one can check ther email on any computer by signing into their account, but the built in Mail app does not have separate user accounts. You can sign into and out of Apple ID's on the iPad but that is where Family Sharing comes into play.

How to use Keychain for multiple users on one computer?

I have a new Macbook Pro with Yosemite. I just moved over from PC for my work computer and the Keychain thing is killing me! I am a social media consultant so I manage multiple accounts for multiple clients. I need a way to log in and out as them on many different platforms. The reality is that I am the only user but I log in and out of different things as if this was a public computer with multiple users.
PC allowed me a drop-down option with each login. For example the email box could be clicked and then I could select the client email that I needed to fill in. The password would then auto-populate. Is there any setting I can change to make this happen on a Macbook? I have been logging in, deleting the info in Keychain, then logging in for the next client, delete...etc.
Most password managers don't work because of this same problem. Please don't recommend a password manager app unless it can handle logging in and out of (for example)10 different LinkedIn profiles.
Any advice would be greatly appreciated!

Sharing an iTunes Library across multiple user account and a network.

Sharing an iTunes Music Library across multiple user accounts.
Hello Everybody!
Firstly, this was designed to be run in Mac OS X 10.4 Tiger. It will not work with earlier versions of Mac OS X! Sorry.
Here's a handy tip for keeping your hard drive neat and tidy, it also saves space, what in effect will be done is an iTunes music library will be shared amongst multiple users on the same machine. There are advantages and disadvantages to using this method.
• Firstly I think it might be worthwhile to state the advantages and disadvantages to using this approach.
The advantages include:
- Space will be saved, as no duplicate files will occur.
- The administrator will be able to have complete control over the content of the iTunes library, this may be useful for restricting the content of the Library; particularly for example if computer is being used at and education institution, business or any other sort of institution where things such as explicit content would be less favorable.
- The machine will not be slowed by the fact that every user has lots of files.
The disadvantages to this system include.
- The fact that the account storing the music will have to be logged in, and iTunes will have to be active in that account.
- If the account housing the music is not active then nobody can use the iTunes library.
- There is a certain degree of risk present when an administrator account must be continually active.
- Fast User Switching must be enabled.
Overview:
A central account controls all music on the machine/network, this is achieved by storing iTunes files in a public location as opposed to in the user's directory. In effect the system will give all users across the machine/network access to the same music/files without the possibility of files 'doubling up' because two different users like the same types of music. This approach saves valuable disk space in this regard and may therefore prove to be useful in some situations.
This is a hearty process to undertake, so only follow this tutorial if you're willing to go all the way to the end of it.
Process:
Step 1:
Firstly, we need to organize the host library, I tidied mine up, removing excess playlists, random files, things like that. this will make thing a bit easier in the later stages of this process.
Once the library is tidied up, move the entire "iTunes" folder from your Home directory to the "//localhost" directory (The Macintosh HD) and ensure that files are on the same level as the "Applications", "Users", "Library" and "System" directories; this will ensure that the files in the library are available to all users on the machine (this also works for networks)
Optionally you can set the ownership of the folder to the 'administrator' account (the user who will be hosting the library.), you may also like to set the permissions of 'you can' to "Read & Write" (assuming that you are doing this through the user who will host the library); secondly you should set the "Owner" to the administrator who will be hosting the library and set their "access" to "Read & Write" (this will ensure that the administrator has full access to the folder). The final part of this step involves setting access for the "Others" tab to "Read Only" this will ensure that the other users can view but not modify the contents on the folder.
Overview:
So far we have done the following steps:
1. Organized the host library.
2. Placed the iTunes directory into a 'public' directory so that other users may use it. (this step is essential if you plan on sharing the library across multiple accounts on the same machine. NOTE: this step is only necessary if you are wanting to share you library across multiple accounts on the same machine, if you simply want to share the music across a network, use the iTunes sharing facility.
3. set ownership and permissions for the iTunes music folder.
Step 2:
Currently the administrator is the only user who can use this library, however we will address this soon. In this step we will enable iTunes music sharing in the administrator's account, this will enable other users to access the files in the library.
If you are not logged in as the administrator, do so; secondly, open iTunes and select "Preferences" from the "iTunes" menu, now click the "Sharing" tab, if "share my library on my local network" is not checked, the radio buttons below this will now become active, you may choose to share the entire libraries contents, or share only selected content.
Sharing only selected content may be useful if their is explicit content in the library and minors use the network or machine that the library is connected to.
If you have selected "share entire library" go to Step 3, if you have selected share "share selected playlists" read on.
After clicking "share selected playlists" you must then select the playlists that you intend to share across your accounts and network. Once you have finished selecting the playlists, click "OK" to save the settings.
Overview:
In this step we:
1. Enabled iTunes sharing in the administrator's account, now, users on the local network may access the iTunes library, however, users on the same machine may not.
Step 3:
Now we will enable users on the same machine to access the library on the machine. This is achieved by logging in as each user, opening iTunes, opening iTunes preferences, and clicking "look for shared music". now all users on the machine may also access the library that the administrator controls.
This in effect will mean that the user will not need to use their user library, it will be provided to them via a pseudo network connection.
As a secondary measure, I have chosen to write a generic login script that will move any content from the user's "Music/iTunes/iTunes Music" directory to the trash and then empties the user's trash.
This is done through the use of an Automator Application: this application does the following actions.
1. Uses the "Finder" action "Get Specified Finder Items"
1a. The user's "~/Music/iTunes/iTunes Music" folder
2. Uses the "Finder" action "Get Folder Contents"
3. Uses the "Finder" action "Move to Trash"
4. Uses the "Automator" action "Run AppleScript"
4a. with the following:
on run {input, parameters}
tell application "Finder"
empty trash
end tell
return input
end run
IMPORTANT: Once the script is adapted to the user account it must be set as a login item. in order to keep the script out of the way i have placed it in the user's "Library" directory, in "Application Support" under "iTunes".
Overview:
Here we:
1. Enabled iTunes sharing in the user accounts on the host machine, in effect allowing all users of the machine to view a single iTunes library.
2. (Optional) I have created a login application that will remove any content that has been added to user iTunes libraries, this in effect stops other users of the machine from adding music and files to iTunes.
Step 4:
If it is not already enabled, open system preferences and enable Fast User Switching in Accounts Options.
Summary:
We have shared a single iTunes library across multiple user account, while still allowing for network sharing. This method is designed to save space on machines, particularly those with smaller hard drives.
I hope that this hint proves to be helpful and I hope everybody will give me feedback on my process.
regards,
Pete.

how to share music between different accounts on a single computer

Multiple users sharing one itunes library

i have multiple users on my mac, but i'd like us all to be able to access the same itunes library. when i go to itunes prefs on one of the other users accounts and redirect their music library to my folder, it says it is doing it, but itunes still goes to their own music folder instead of mine. i can share my library with the sharing pref, but while they can now listen to my music, they still can't use it in imovie. is there any easy way around this problem??
thanks for your help.

I wrote a simple shell script that executes each time a user logs in (well, actually, each time I log in, coz' it's not really applicable to other users). It syncs my work and home addressbooks and iCal calendars to one another.
I named it "sync". Then I read somewhere that if you wanted to make it double-clickable (to launch it from the Finder), I appended a ".command" filename extension (so it's now named "sync.command"). I also did a chmod 755 to that file so that it had execute privileges. Depending on whether you give each user their own copy of this thing, or keep a single copy in, say, the /Users/Shared directory, you may have to play around with chmod. Whatever, just so long as the user that has just logged in has execute permissions to the file, and to the entire path to the file, you should be good.
Then, in SysPrefs > Accounts > Login Items, I added that "sync.command" file to the list. So, really the only difference is I'm not wrapping mine inside an Automator script like you are.
I had tried adding it to ~/Library/LaunchAgents and make a launchd plist for it, that would kick it off at login. But I didn't get that to work. Don't know why. But just adding the double-clickable executable unix script to the Login Items list did the trick. Whether the plist has to hang out there with it, I don't know. I still have it there, though, in case I ever get motivated to figure out what's wrong with my launchd plist file. So, if just adding it to the Login Items list doesn't do it for you, you could try making a (functional?) launchd plist for it and plopping them both in ~/Library/LaunchAgents, too. That's how I am now, and, like I said, it launches at user login as that user's process (not as a root process like the above referenced article said how login hooks worked -- although, you may want it to run as root since you want this to work with multiple users...in which case, you might want to listen to Cole and not me...).

How can I have multiple users on iTunes (in order to connect to a shared office iPad)?

How can I have multiple users on iTunes (in order to connect to a shared office iPad)? Currently each of us has our own iTunes account, so I've made an "all office" Apple ID. However, I can't seem to get two different accounts (my personal and the office) to work on my machine. Even when I login as "the office", my personal library is still showing. Additionally, when I try to setup with a first-time use in iTunes, I get an error that I don't meet the minimum age requirement - no matter what birthdate I enter!

The library exists regardless of which user is logged in.
The only way around that is to create different user accounts on the computer.
There is no way to have 20 unique iTunes users access a shared iTunes under a single login on the computer.

How to use Final Cut Pro with multiple user accounts?

Hi,
I want to use Final Cut Pro on a clean user account. How do I set it up? How can I access my old FCP library and still work on it from multiple users?
Also, I want my DropBox account to back-up my media. Any tips?

I use external drives as backup. But I don't trust them. And in case of fire or what ever...It is of no use...
But I agree on your comment about DropBox. It would have been the perfect solution though.
What else is there?
I have a 2TB HD but these projects are huge and still growing - so I have to move my projects to several external drives. So maybe I should just work directly from external drives and skip the partition of the computers main drive? I am thinking of the disadvantage of reducing the total storage of the disk.

How Can I Login To Multiple User Accounts Simultaneously

I am using an Intel iMac (2GHz Intel Core 2 Duo) with 1GB of memory and 10.4.11. I have Fast User Switching enabled. I restart the Mac every morning. Then I login to a second user account. While at work, I access these accounts via VNC.
Sometimes I forget to login to the second user account. I do it from work via VNC, which sometimes causes complications.
Does OSX support simultaneous multiple user account login? If not, is there a work-around solution such as an AppleScript? This would provide a time savings to me, as well as a convenience if I forgot to login to the second user account before leaving home.
Thank you.
Kurt R. Todoroff

Seems to me, in another discussion, the simple Fast User Switching does not
do much really fast or automatically; there are a few faster steps than having
to log into each and every account change (even when FUS is enabled) so
this later development sounds a little more automatic, esp over a distance.
Is there a third party app or valid script that an do the multiple logins automatic
after the first-run; so passwords need not be re-entered, and the screen can just
switch over "fast" to another open account window, ready to go to work in there?
{And not just a keyboard shortcut to save a few little steps, overall.}
Whichever way the road turns...
Good luck & happy computing!

How to use the same POWL query for multiple users

Hello,
I have defined a POWL query which executes properly. But if I map the same POWL query to 2 portal users and the 2 portal users try to access the same page simultaneously then it gives an error message to one of the users that
"Query 'ABC' is already open in another session."
where 'ABC' is the query name.
Can you please tell me how to use the same POWL query for multiple users ?
A fast reply would be highly appreciated.
Thanks and Regards,
Sandhya

Batch processing usually involves using actions you have recorded. In Action you can insert Path that can be used during processing documents. Path have some size so you may want to only process document that have the same size. Look in the Actions Palette fly-out menu for insert path. It inserts|records the current document work path into the action being worked on and when the action is played it inserts the path into the document as the current work path..

There are multiple users with the same display name

Hi,
We have a user and when she get an item assigned to her she sees the following alert:
"There are multiple users with the same display name USERNAME and at least one of them does not have read permissions to some of the files"
Now I looked in the database and when I run the following query with the username:
SELECT
[ProviderDisplayName]
,[DisplayName]
,[HasDisplayName]
,[Domain]
,[AccountName]
,[UniqueUserId]
,[LastSync]
FROM [Tfs_Configuration].[dbo].[tbl_Identity] where displayname like '%USERNAME%'
Then I get 2 same usernames back, How can I get rid of one of them ? When I access TFS trough the portal I only find 1 occurence of this user.
We use VS2013 and TFS2013 update 4
Best regards

Hi DSW,
Thanks for your post.
In your query result, please check if these two users have the same Account Name. if they are two different Account Name in result, it indicate there’s two users have the same display name in your AD, please check that two users’ information in
your AD. We suggest change one user’s display name in AD.

Multiple Users Mounting the Same Network Share?

Hello, first time posting...
I'll cut right to my main question: Is it possible, on OS X v10.3.9, for multiple users to simultaneously connect to the same network share?
Here in my office, we have a single Mac that is used by multiple people throughout the day. It has two accounts on it, 'Communications' and 'Studio'. 'Communications' is an Admin account that is used by a co-worker who spends the most time on the Mac. He created the no-limitation 'Studio' account for the rest of us to use.
There is a certain Windows network share that we both frequently use. We've found that if one user connects to the share first, the other user will not have access to it; using 'Go -> Connect to Server' will result in the share being greyed out in the list, and the share will not show up in the Finder.
However, there is one way around it. If Studio connects to the share first and then Communications (the admin account) attempts to make a connection of it's own *through a shortcut on the dock*, then a 'clone' of the share will be created on Comm's desktop, with a "-1" after the name (though it might be some other number).
This may sound like I've answered my own question, but what I'm looking for is a way for the non-Admin account to access the share after the Admin account already has (so that we don't have to log-in and disconnect Communications everytime Studio needs to manage files on the share).
We have Thursby Software's DAVE installed on the Mac, but I'm not sure how it fits into all this.
Any thoughts, suggestions or advice?
Thanks.

Bizarre. It turned out I could merge them, but only in to the mapped drive - L: - and only by explicitly clicking on the drive icon - if I typed L:\series in to dialog box it converted it back to \\nas\share\series... Not helpful.
