Fast user Switching breaks iTunes Library on Drobo FS

Hello, Everyone.
I realize this is a bit of a corner case but what the heck, maybe you can help.
Our home iMac has two main accounts, husband and wife. Connected to it is a Drobo FS. iTunes media is on the Drobo FS. The iMac Husband account is used to power the whole house media from any device:
iPhone
iPad
AppleTV
Mac Mini
When any of these devices wants any content on the iTunes Library from the iMac stored on the Drobo FS they connect using Home Share. Life is good. But life turns bad quickly when Wife logs in on iMac thus automatically causing the Husband account to be logged out. The iTunes connection to Drobo FS breaks and homesharing is disrupted. Finally when fast switching back to the Husband account iTunes and Drobo FS seem to always be broken. The fix is to shut down iTunes and restart it.
Does anyone have tips on how to better this home theatre evironment.
Thanks,
G4M

But I like Fast User Switching! Any better solutions?

Sharing one iTunes Library with Fast User Switching

Last year, I started using one MacBook Pro for Office use and Personal Home use, by creating two user accounts on it, and enabling Fast User Switching. I did this when I gave up using two separate desktops macs.
Now I have two rather similar music libraries, taking up too much hard drive space. Once I enabled Music Sharing in my Office iTunes Library, I realized that I could gain access to that Office Music Library when I am on my Personal Home User account. Since my Library on my Office account is the most complete, can I eliminate the iTunes Library on my Personal Home User account, to save hard drive space?
If so, how should I do this?

Since my Library on my Office account is the most

Personal Home User account, to save hard drive

Yes.
If so, how should I do this?
Move the iTunes folder in Home/Music on the Personal
Home User Account to the desktop.
Launch iTunes. Unable to locate a library file, it
will create a new one, empty one in a new iTunes
folder at Home/Music.
Connect to your shared library as usual. If
everything is working as expected, trash the iTunes
folder on your desktop.

My iTunes was created under an admin. user profile that I would like to delete. I created a second profile also with admin privlages but I want to delete the first because I messed up the shortname on the profile. So, if I delete this first profile, will I lose all of my music? Will I lose access to the music?

IPod/iTunes issue with Fast User Switching

I have Fast User Switching enabled on my iMac Core 2 Duo running 10.4.8. My daughter usually leaves her iPod connected and it is causing problems when switching to another user. Other users get the message that the connected iPod is associated with another iTunes Music Library and constantly asks if it should be erased. While nothing has happened yet, there are 4 of us using this and I think it's only a ametter of time before somebody inadvertantly blows away her iPod.
Is there any way to disable this this?

Let me try to elicit a more helpful response...
One of the problems I am encountering with an iPod connected and using fast user switching is that if the iPod is syncing with one user, and I switch to another user, the second user sometimes will try to take control of the iPod and sync with the second user's library.
Is there a way to tell Mac User's 2 account to ignore User 1's iPod?

ITunes with fast user switching.

One day I was listening to a really good and song and found that I need to switch to another account on my Mac so when I switched it stopped my music and I was like crap I have when I have to switch users when listening to music. So I was thinking how cool would it be if when I switched user if itunes would just keep playing so it would not interrupt me. Does anyone know how I could accomplish this?

Now that I'm running Leopard I can say that is still happens; iTunes stops when switching accounts through Fast User Switching.
Except yesterday iTunes kept playing for some reason. At the same time it seemed like Fast User Switching was broken, at least from the account with iTunes playing. Only the Login Window choice was enabled. So it might be that selecting a user directly is when iTunes gets stopped. However I don't know how to get it to work that way again since the login window option is not available when Fast User Switching is turned off—you can only Log Out (which of course turns off everything).
Maybe an enterprising programmer can fix this lack of choice in Leopard.

ITunes 7.7 pauses with Fast User Switching

As far as I can tell iTunes 7.7 now stops playing songs after I switch users. I'm using 10.4.11. Has anybody had this problem in Leopard?
I really want to hear songs continue playing from my work user account when I switch to my personal account. Any ideas?

Home Sharing stops working with fast user switching

I have a late 2013 iMac running Mavericks. The main account has my iTunes library with Home Sharing enabled. The AppleTVs and IOS devices can see the Home Share and it works well. But, it stops working when user accounts are accessed on the Mac.
For instance, as soon as I select "Login Window..." from the fast user switching menu, the share is lost. I did not log out, iTunes is still running. I simply showed the login window. All IOS and ATVs loose the share. Switching to another user also stops the share. It's as if iTunes is completed halted and not allowed to run in the background.
When moving from the login screen back to the user account where the iTunes library is located, the home share is restored. Likewise, moving from a 2nd user account back to the main account where iTunes is runnning restores the home share.
I have a MacPro running Mountain Lion, and it works fine. The iTunes library is always available for the devices, even if multiple users are signed into the Mac, or if the Mac is on the login screen.
Any work around for Mavericks? It competely breaks the entire media ecosystem if every device looses the home share if someone tries to use their account on the Mac.

And just like that I may have found the solution! IT suddenly occured to me that one of the settings that got changed when we imported my wife's profile was a change to the sleep settings. Previously, I had had my iMac set to never go to sleep, since it shares our media with the rest of the house and runs eyeTV to record TV shows and such. For a little while after my wife's account was imported the settings to changes so that the computer would go to sleep after 15 minutes. I'm not totally sure why, but I think having that set up somehow meant that when we switched accounts my other account just "went to sleep" and therefore stopped sharing the iTunes library. After I noticed the change and switched the computer back to "never" for sleep the problem seems to have stopped.
So perhaps check your sleep settings? That seems to be the only change I can think of that got things working correclty for me. I'll keep digging though and see if I can find any more helpful info. Good luck!

Can Multiple Users Share an iTunes Library?

Hey all,
There are two user accounts on my MacBook Pro, mine and my wife's. I manage my iTunes library on my account (buy songs, update playlists, automatically download podcasts, etc). When we switch to my wife's account and open iTunes on her side, the library is empty and iTunes prompts her to get started like any first-time user.
Is there a way to share and control the same library across both accounts? I.e. opening and managing iTunes on one account is no different than doing it on the other.
Any help would be appreciated.
Thanks,
Chip

Geez.. What the article describes sounds like what I have in mind, but it looks like some pretty serious permissions tweaking.
The one line that concerns me is this:
"Note that iPhoto (iTunes) will be smart, and will not let two or more users tinker with the shared iPhoto (iTunes) library at once through fast user switching."
My wife and I are typically both always logged in, and we use Fast User Switching to move back-and-forth between accounts. So, if one of us has to close iTunes before the other can tinker with it, that kinda defats the whole purpose.
Am I reading that right?
Either way, I'm definitely going to back-up my library before trying any of this.
Thanks for the help,
Chip

Fast user switching and "ipod is in use by another user on this computer"

Is there any way to suppress the "ipod is in use by another user on this computer" message that appears when you use fast user switching.
my wife and I share a mac pro and when flipping between sessions, this message gets to be a bit annoying. i.e. if her itouch is plugged in and she is managing it through her library, if I fast user switch to my session, I get the warning dialog (ok to clear) I mention above. This is kind of annoying now, since I understand I won't be able to manage that ipod from my itunes session.
is there anyway to suppress this behavior?

Hi again,
Glad to hear you got all your music files back into your library.
I've seen this iPod error before, but I don't know why it occurs. In my experience, restarting the computer solves the problem.
Cheers,
Sara.

Fast user switching notifications

Apple has provided documentation on how to register an application to receive notification of fast user switching. But that document is way, way, way over my head.
I'm trying to write a simple app or script, with Automator or whatever, that will receive the notification that a user has switched out, and then tell iTunes to quit. So basically I'm after a tool that will quit User A's iTunes as soon as User A's account is switched to the background.
Can anyone help me make heads or tails of the document I linked above, or help me out on this?
Thanks!

Also for me this is way over my head, but I think this communication prompt script might help you out developing your automation.

Hope this helps

Screen has a bluish tint after fast user switching and then warning tone

Hi all I'm having a bit of a problem that I hope someone can help me with. First the details, I have a MBP bought in late '07 and running Tiger. I was doing full backups using "Backup" and I also had Safari, iTunes, and Word open. I briefly switched to my other account using fast user switching and when I returned to the original account the whole screen had a blue tint to it. Like the color profile was off. This has happened before and a restart usually cures it, I haven't restarted yet but I am fairly certain it will correct the problem this time too. But is there anyway to prevent this? My second question is the one I'm more worried about. It also has happened before but usually when using more CPU intensive applications. When I went to System Preferences and opened up the display preferences in an attempt to correct the previous problem I heard a very loud tone. Like some type of warning tone, it was loud enough that it startled me. I had iTunes playing and after the tone the music got very quiet but relaunching it brought it back to normal. I'm just wondering is this some type of warning tone? Is it something I should be concerned about? Besides the music everything else seemed unaffected, although the previous times that this has happened usually when using handbrake there was noticeable problems after the tone (like applications crashing). All of these problems are gone after the computer is restarted though. Does anyone have any insight on these issues? Thank you.

OK I ran TechTool and everything passed except for the volume scan. Then I checked this with Disk Utility and the HD failed for a few minor reasons, like invalid block count. I repaired it using the fsck -fy command in single user mode. The computer seems a little faster now. I don't know if this error is related to the beep in any way, I may try talking to an Apple genius to see if they know. Since it seems like pretty minor errors I'm not too worried about it but it does seem to be happening often. The last time I had this error was when I posted a question here about it which I just checked was on March 1st. So this error happened again after a little more than 2 weeks which seems excessive to me. Any thoughts?

How to get "fast user switching" and network shares playing nice

I've been alternating between banging my head against a wall and reading every forum I could find to try and get a reasonable compromise between using "Fast user switching" and sharing a folder from a file server. It baffles me how the network share/mount model of OSX/AFP is completely killed by fast-user-switching; this is a big problem with Apple requiring users to be actively logged in to share music/video from iTunes which therefore essentially requires fast-user-switching if anyone else wants to use the computer. (anyone find it odd that you can share files without being logged in, but sharing songs requires an active login for each user who is sharing? Apple: time to make iTunes sharing a service!)
For the sake of example, lets just say I want to share my /Groups folder from my desktop and have it be accessible to my laptop. Here are all the things that I tried:
Apple Method 1) Share /Groups in the Server.app on the desktop (running Lion Server), use finder on the laptop and drag the share icon to "Login Items", alternative use a startup Apple script using "mount volume" Both of the options work and will mount the /Groups folder under /Volumes/Groups, of course when the second person logs in via fast-user-switching (and occasionally the first person for no apparent reason), they will get /Volumes/Groups-1 since /Volumes/Groups is already taken. Tomorrow we log in a different order and now the previously /Volumes/Groups-1 user has their mount at /Volumes/Group and vice versa. Any links, aliases, finder sidebar references, and application settings which pointed to yesterday's location are now BROKEN. Not very user friendly to my mother-in-law who is trying to find those pictures of the kids and doesn't know anything about mount points. I also can't reasonably mirror the file location structure on the desktop so that application preferences that are synced between the two (portable home directories) work. fail.
Apple Method 2) Use automounter and set up by hand direct maps for /Groups or an indirect maps for the children of /Groups. Now it will automatically get mounted to /network/servers/SERVER/Groups/ on the laptop and on the desktop it will automatically create a similar symlink structure so that the same path (/network/servers/SERVER/Groups) work both on desktop and laptop. Cool. Except when the second person logs in, the /network/servers/SERVER/Groups/ mountpoint is already owned by the first user and they don't have any permissions to access it. Fail.
Apple Method 3) Use mount_afs and specify directly the mount-points. Have each user have their own startup AppleScript which mounts /Groups to a different location (e.g. /Users/Shared/username/Groups) that way they don't conflict with multiple users. On the desktop, set up symlinks from /Users/Shared/username/Group to /Groups so that it will be the same as the client and applications settings will work when synchronized back/forth by portable-home-directories. Will it work, yes it does, but what a bear to maintain. Is this really what I should expect to do just to have multiple users on my desktop and laptop (which again is essentially required now if I want to do any type of iTunes sharing). This can't be what apple expects.
What I ended up doing - the "not quite apple" solution.
Non-Apple Method 4) After a read of "Autofs: Automatically Mounting Network File Shares in Mac OS X" (http://images.apple.com/business/docs/Autofs.pdf) at the very end there is a single paragraph of "Kerberized NFS": "A Kerberized NFS mount can have multiple connections from multiple users, each using the correct user’s credentials for each transaction. This allows administrators to support multiple users, each authenticated with their own credentials to the same mount point. This is very different from AFP and SMB mounts," (emphasis mine)
It appears that by using good 'ole NFS (abeint with Kerberos for security!) you can actually have multiple users on the same mount point. Roughly following the guidance at https://support.apple.com/kb/TA24986?viewlocale=en_US. What I needed to do was:
1) create /etc/exports on my desktop and add a single line "/Groups -sec=krb5". The existence of /etc/exports triggered a start of nfsd which no longer has any GUI options in Lion.
2) Add a line to /etc/auto_master on my laptop "/- auto_mymounts" to reference a new direct map.
3) Create /etc/auto_mymounts and add a single line "/Groups SERVER:/Groups" to create the direct map.
THAT'S IT. Three lines in three files.
Now when I log into my laptop, there is a /Groups that is a network mount of my desktop's /Groups, same location AND it works for all of my users, even simultaneously.
In the end I'm happy with what I've got, but man was this a difficult path just to support fast-user-switching. In Lion, Apple appears to be getting away from NFS (no longer turned on by default and remove from the GUI controls) but clearly this really useful functionality which doesn't exist in AFP.
I'm really curious, after all this work. Any other ways to accomplish this?

In my example above, yes I chose to mount the share "Groups" to the top of the root since that is where I put it on my server and I wanted to keep them similar; but that was just my preference, it isn't a requirement. You can export and mount from other directories.

Fast User Switching with Mounted Network Drive?

I have a headless G4 Cube running 10.5.8 with a 2TB firewire drive plugged in for storage accessable to any of my macs here at home. I can access it fine with my 2 desktops over ethernet and wirelessly. Recently we decided to consolidate our 2 desktops into one using the muliple users feature. Seems to work fine, and both accounts can access the shared drive. They are logging in with the cube's admin credentials, and the shared drive is set to ignore permissions. I have the drive set to mount on login with a startup item in the system login items prefs. As long as I logout before switching users, everything is good.
The problem arises with Fast User Switching which we'd love to be able to use. I can't figure out how to connect to the drive in one account without the 2nd account then seeing it as a volume without proper permissions, then that account creates a new volume mount for it (which doesn't work with iTunes properly and seems to cause other wierd issues).
Example: So say 'user1' logs in, mounts the drive 'Jukebox'. everything seems OK so far. 'Jukebox' is on the desktop and iTunes finds the music. Now I fast user switch to 'user2' and there is a 'Jukebox' on the desktop with the red minus icon indicating I don't have permissions to access it. If I then browse the network and mount the drive, I end up with ANOTHER 'Jukebox' on the desktop. BUT iTunes doesn't see it properly. If I look in the /Volumes/ folder with the Terminal, I see a mountpoint for 'Jukebox' (with the owner of 'user1' group 'staff') and now a new mountpoint called 'Jukebox-1' (with the owner of 'user2' group 'staff').
It seems when you mount a AFP drive, it creates the Volume with the current user and staff group, but switching to another user then can't access that when it sees it in the /Volumes folder. You try to mount again and it creates a NEW mountpoint, names it with a '-1' at the end and you can use that (but iTunes cant).
So... how does one use a shared drive that you want on BOTH users desktops with Fast User Switching turned on? Is there a way to have the drive mounted BEFORE either user logs in, such that it will be seen as any other local drive (which doesn't have the issue)??
Or is there some other way I can attach to the network volume in each account on login so both have access to music and videos with full permissions?
I'm really stumped here after 2 hrs of googling, searching here and trying things.
TIA

I've not had any luck with the suggestions in the link either.
Here's two other approaches I've tried and failed with:
1. Creating a new share point on the cube itself so that one user can mount it as a different volume. Then the issue is that I still don't have a volume named "Jukebox" available to each user when switching. I DO have access now to the data from both accounts, but under 2 different mount points (volume names) and the xml file for iTunes is hard coded with the path for each mp3 including the "Jukebox" volume name... so no go.
2. Tried figuring out a way I could script a mounting of the share with the terminal thinking I could then run that shell script at startup. Can't seem to get the sytax right. If I create a directory in /Volumes and mount and afp share to it, it takes on the ownership of root/wheel which I can't access in the finder and can't seem to change.
BUT I'll keep playing with both these ideas a bit... the first one might be overcome with a bit of logic and the 2nd if I can get the syntax right to mount the share with afp_mount and give it the correct ownership/permissions such that when a user logs in she/he sees the volume on the desktop and has full r/w access to it.
thanks again. if you offhand know the syntax for that, let me know

10.9.3 = major problem with fast user switching

I've found a major problem with the 10.9.3 update with my 27" iMac, you probably won't see it if your on a laptop. I did all the updates in past few days i.e., 10.9.3 combo update, iTunes 11.2.1.
Afterward I noticed a bug when Fast User Switching i.e. FUS. I have 5 accounts but the bug can be replicated with only 2.
I login to userA have some windows open but you can just open a Finder window. Now make the window at least half the with of the screen and move it to the right side of the screen. Then login in to userB and setup the windows the same way as userA. Now FUS to userA and then back to userB. You will notice that the Finder window has been moved to the upper left corner of the screen. This problem happened's to all user accounts you login to except the first account you logged into.
Since I didn't know what update caused the problem I had to use Time Machine to revert to my last version of 10.9.2. I then double checked the for the bug and sure enough everything was working fine. I now was going to install one update at a time and to see which one was causing the bug. So I installed 10.9.3 first and found the bug immediately.
I now know what's happening. When the switch occurs the screen is resized to about the equivalent of a 13" MBP. At this point the windows that fall some ware outside that size get moved to the upper left corner and resized. Then the screen resizes to normal but it's too late, all the window have moved and been resized to fit the 13" screen size.
You can reproduce this effect by going to System Preferences and selecting Display and then select the Scaled radio button. No select the smallest size, say, 1280 x 720. Now select the Best for display radio button again. You will now see all the windows you have open that were too big no moved and resized to the upper left corner. I know why the Mac moves the windows, it's so you don't have any windows stuck off screen.
Now when I say 13" it could be some other size but it's about that size give or take.

Yes, it's when you user Fast User Switching.
Here's snapshot before the screen resized. Ignore the window in the lower right, I moved it from the upper left before taking the screen shot.
I hate to say it but I'm glad I'm not the only one with this bug.

Network Drive problems with Fast User Switching

I have a USB drive connected to my Time Capsule and shared to the network. On one of my computers (Mac Pro) I have 2 user accounts which access the data (music, photos). The first one to access the drive after a power on has no problems, and everything works perfectly. However, if I Fast User Switch to the other account, it can see the drive but cannot access it (permission problem apparently). I then have to click the disconnect button in finder, and reconnect, and then can use it again fine. Then when I switch back to the first account its the same deal, having to disconnect and reconnect. It is really annoying, since it marks all my itunes songs as missing and whatnot. Does anyone know how to fix it?
Thanks!

Yes, under Sharing in System Preferences both users have been added to full access of the drive. I had to do that for the non-admin account to be able to access it at all.

OS 10.4.6. has broken dialup connectivity when using fast user switching

I installed OS 10.4.6. It seems to have broken dialup connectivity when using fast user switching when switching from one user to the next.
For dialup, it is extreamly annoying that I can not resume downloading a file from were it got cut off, but now, if another user wants to check their email, my download always gets broken and has to be restarted. Dialup is slow enough with out having to start from scratch even more frequently, now.
Also, in earlier versions of 10.2 or 10.3 (I don't remember which), I was able to switch users and maintain listening to a single users' iTunes.
I would like to be able to switch users and not lose either my dialup network connection or the primary users currently playing iTunes songs.
Perhaps for iTunes, one should be able to chose to mute another users' instance of iTunes, if it is currently playing.
Mini-Mac 1.42GHz 80GB BT/AE Mac OS X (10.4.6)

I have not tried replicating this but might be able to provide some additional information.
We use network login accounts on our desktop computers. Fast User switching deliberately will not work for multiple network login accounts. (Remember network login accounts normally also have an associated network home directory mounted via AFP.)
Now a bit of background about volumes and mount points under Mac OS X. Under Mac OS X, any additional drive (or more accurately 'volume') is listed under the 'Volumes' folder, remember also that Mac OS X is a Unix operating system. So just as normal for Unix, the boot drive is '/' or the root level and Volumes is a folder in it. The underlying Mac OS X software automatically 'attaches' and additional volumes as sub-folders in the 'Volumes' folder (in Unix speak these are called 'Mount Points'), if you have an external hard-disc called 'Fred' then this would be represented by the following path
/Volumes/Fred
If you happen to have two volumes with the same name connected at the same time then while in the Finder they may show up with the same name, in Unix they would have different names automatically assigned to keep them separate like so
/Volumes/Fred
/Volumes/Fred 1
Now getting back to the Fast User switching problem and AFP volumes, when you login to a File Server volume it also is automatically added to the Volumes folder, so if we have a File Server volume called 'Shared' it would look like
/Volumes/Shared
With Fast User switching potentially both user accounts could be accessing the same /Volumes/Shared which means both user accounts would be talking to the server via the same File Server login, hence the possibility for one of the Fast User accounts to be using the 'wrong' permissions.
