Can multiple users share Aperture Library over network

I'm considering moving over to Aperture because iPhoto is starting to show the strain under the number of RAW pictures I'm uploading. My current iPhoto library is stored on my NAS and is shared between my RMBP and MacMini. If I make the transition over to Aperture will I be able to have the same set-up?
Thanks

iPhoto is starting to show the strain under the number of RAW pictures I'm uploading.
What do you consider to be a "strain"?
Poor response time? I suspect, that will be more due to the network access on a NAS than to the library size.
You might try to put your Aperture 3 library on a NAS, but it is not recommended by Apple, see:
Use locally mounted Mac OS X Extended volumes for your Aperture library
You will have to ensure,
that you do not open the Library from both your Macs at the same time,
and you will have to ensure, that the library is only on a disk formatted "Mac OS X Extended". SInce your NAS has a different formatting, put the Aperture library onto a disk image on the NAS. You will have to mount this disk image, before you access the library, like recommended here for iPhoto, see: iPhoto: Sharing libraries among multiple users http://support.apple.com/kb/HT1198
But as I said, if poor performance should be your main reason for switching from iPhoto to Aperture, you will not gain much, if you keep the library on a network attached volume, unless you have a very fast network connection.
The best performance you get in Aperture with the library on the fasted drive you have. I keep my Aperture library on the internal SSD and the original master image files (the bulk of the data) on a second internal drive.

Best way to share aperture library over network on two computers?

I've read several posts about doing this and most recommend using an external HD and just hot swapping. However, is their not a better alternative? Can I not share my library over the network, or just remote connect to the other computer?
Thanks for the help!

Hi Terence and Leonie,
You can run several Aperture on the same computer as long as all Aperture are using distinct libraries.
What Aperture does is to create a simple lock file in <your Aperture library>.aplibrary/Database/apdb The lock file contains the PID of the process. So not two Aperture could open the same library (although I don't know how good they have manage the concurrent creation, locking, verification of this lock, this is a typical and difficult software engineering problem)
Anyway, I have not said that Aperture supports concurrent editing. That a file is a database or a simple text file, you have basically the same issues on network or in concurrent environment. So if the folder structure holds simple, flat text file or xml object or databases, it is still a bunch of files (this is a UNIX system by the way ).
Aperture contains more than one SQLlite file, there are some at the root folder, some under Database/apdb etc. there are also XML files that could be used as database.
Anyhow, editing a file (SQLlite, XML, txt, doc, etc.) either on a share or locally is plain similar. The drive can fail too, although much less likely than the network.
Network file edition can have a few shortcomings, but nothing that when known can be blocking.
Locking files over the network can however be tricky and depends largely on the network protocol used (NFS, SMB/CIFS or AFP just to name a few). In addition, if you import files from /Users/foo/Photos in Aperture (without copying them within Aperture), they might not be visible from another computer or only the previews, as the path /Users/foo/Photos is not "visible" from the other computer.
What really is a problem when you put a file not locally is the file system type and its features. HFS+ supports extended attributes (metadata), many other file systems support these but the API (how the software, such as Aperture, access this feature) might not be similar, in addition the amount of metadata or their structure might differ from file system to another. And this is where you might lose information.
A tool like Dropbox is pretty good at maintaining the metadata across different computers, and it has been adapted to do so for OS X specifically (and also for Linux and Windows).
The second problem is if you would have a Mac and share via SMB (the Windows share network protocol, aka CIFS on recent Windows versions) the library, SMB might not support the reading and writing of HFS+ metadata, thus data loss might occur.
Apple is just warning us of all these shortcomings, and advise to use local storage formatted as HFS+. Because even a local external disk formatted as NTFS or other file system could be a problem.
However, power users who understand the risks and limitations of a network share (in general) can create a disk image on a share (even if it is SMB). As for OS X, once the disk image is mounted, it is just like any other local hard disk, it is just "slower" especially latency wise. OS X supports perfectly disk image mounted on a share, it takes care of properly synchronising it.
Of course, due to the nature of the link between the application data and where they are stored, in case of application or OS crash, the amount of data loss could be greater than when the data are held locally.
I hope this clarify better my post.
Note: another shortcoming of having it on the network is: Aperture lock the library by creating a file with a process ID. If the same library is opened from another computer on the network, this other Aperture instance might see the lock file and could perhaps not find the corresponding running process. This Aperture instance might then decide to ignore the lock and proceed with opening the library. This might have some consequences.
But I haven't developed Aperture so I don't know how it would behave

Share Aperture photos over network

Hallo every body,
iam searching for a solution, how to share photo over network for a long time, in our company we have 40 macs(imac, mac bookpro) and 3 xserve, vtrak and 30pc. and we have round about 30000 pic they are saved in iphoto library on one of the xserve.
My Boss wants from me to find a solution to share these photos over network. the mac users must use iphoto to access these photos.
which program shall i install on the server so that the client users can access the photos from there macs through iphoto.
at the beginning i used the share library option in iphoto, until iphoto 9.1.1. By iphoto 9.1.1 on the client when i click on the shared library my searching field disappears and i cant search in the shared photos.
I thought Aperture is the solution, so i shared the aperture library over the network (with afp protocoll) but in order to access the network aperture library, first i need to install aperture on the client and then i open iphoto and from iphoto option i can choose the option access aperture library.
how can i solve it without to install aperture on the client, is there any iphoto plugin so that i can access aperture library without installing aperture
or is there somebody uses another solution???
please help
best regards
Tony

Neither iPhoto nor Aperture is the solution for this.
The idea of using iphoto on the client machines is wrong, it's just not designed for that use. Iphoto is designed for a family with a point and shoot camera, or even a phone. Aperture is a pro level photomanager. Installing Aperture on all the mchines means you will have to purchase the app for all the machine, you need a site licence.
Also, it won't work anyway. You can't share an Aperture Library like an iPhoto one an only one user can access the Library at a time. So, one of the users acesses the Library and all the others are locked out.
Neither are what you need: you need a media server application. A pro level media server. Tell your boss he's fooling himself if he thinks anything else will work reliably.

How can multiple users share a catalog?

PSE 5 - We have multiple users sign on to the same PC. The catalog is created on a network drive that all have access to. Photos added to the catalog by one user are not accessible by another user. Is the catalog profile-dependant? Is there some setting I am missing?

The users can open the photos directly in Windows Picture Viewer but, for some users, the catalog looks empty in Photoshop Elements.
1. Verify that each account is indeed loading the same catalog. Do Help > System Info within the PSE Organizer to verify the catalog name and location is identical. Perhaps one or more the accounts is opening another default (empty) catalog.
2. Ensure the Organizer is showing you all the files:
a. In View > Media Types, check all the types.
b. In the Organize pane on the right, check Hidden to see if any of the cataloged photos are marked "hidden".
c. Do Fine > Clear Date Range.
d. If Back To All Photos is showing in the upper right, click it.

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

Can multiple users share 1 address book w/out MobileMe?

To date we've used MobileMe, so synchronizing our address book amongst two user accounts (1 MacBook) was easy. However, that's the ONLY service of MobileMe I use anymore. It's just WAY too expensive for what it provides, especially compared to free services like Google. Thus, we're not renewing.
QUESTION: Is it possible to copy the address book file to a shared folder and share it like one would an iphoto or itunes library? Just checking before I try it, in case something explodes. Also, where is the file located? Thanks in advance!
p.s. Sorry if this is a repeat (likely)- I checked the first several pages and couldn't find anything.

You could try Address Book and Calendar Server (http://www.addressbookserver.com) which lets you share your contacts with your own server running on your own network.
PS: I am the developer of AddressBookServer so naturally biased towards it.

Can multiple users share one file for iphoto

I want to be able to have all the user profiles on our iMac access the same files for iPhoto, so when one user adds photos they are there for anyone who logs on.

For iPhoto 09 (version 8.0.2) and later:
What you mean by 'share'.
If you want the other user to be able to see the pics, but not add to, change or alter your library, then enable Sharing in your iPhoto (Preferences -> Sharing), leave iPhoto running and use Fast User Switching to open the other account. In that account, enable 'Look For Shared Libraries'. Your Library will appear in the other source pane.
Any user can drag a pic from the Shared Library to their own in the iPhoto Window.
Remember iPhoto must be running in both accounts for this to work.
If you want the other user to have the same access to the library as you: to be able to add, edit, organise, keyword etc.
Quit iPhoto in both accounts. Move the Library to the Users / Shared Folder
(You can also use an external HD set to ignore permissions, a Disk Image or even partition your Hard Disk.)
In each account in turn: Double click on the Library to open it. (You may be asked to repair the Library Permissions.) From that point on, this will be the default library location. Both accounts will have full access to the library, in fact, both accounts will 'own' it.
However, there is a catch with this system and it is a significant one. iPhoto is not a multi-user app., it does not have the code to negotiate two users simultaneously writing to the database, and trying will cause db corruption. So only one user at a time, and back up, back up back up.

Can multiple users share a single Email Account?

I set up my email account last night and everything worked perfectly. Messages downloaded from my ISP with no problems. Then I logged out of my user account and logged into my wife's user account. When I clicked on mail to test it, I realized that it is assuming she will be checking mail from a different email account. Is there a way that our seperate user accounts can share the same email account?

Technically, yes, you should be able to do this... the issue is why do you want to? If you set up her user account Mail (or whatever e-mail application you're using) preferences with the same information you used for yours (mail account name, password, SMTP information) and make sure that the "leave message on server" box is checked in the Mail preferences for both user accounts, the messages for that e-mail account can be downloaded to both user accounts. The problem is that each user would have to delete messages meant for the other. Depending on what type of mail account (IMAP, POP) it may also mean that the "new mail" status of a message may not be correct. A message read in one user's account may show up as "read" in the other. It's much tidier for each user to have their own e-mail address.

Can multiple users share the same DB ?

We have about 10,000 + personal photos. Can I install the LR Database on my server so that my wife and I can both be adding metatags to the photos at the same time ? I don't mind if I have to buy 2 copies, but I am more concerned about sharing the database. Any Ideas ?

i would not advice to do it but....

How can I sync Iphone to a PC calendar then have multiple users share that calendar? Is there an application that does that?

How can I sync Iphone to a PC calendar then have multiple users share that calendar? Is there an application that does that?

If it is actually an exchange calendar, and it's not linked to a specific user, it should be possible to simply add the exchange account to each device in question and have that exchange account only sync the calendar. Then every user has access to the same calendar and can add/edit entries to the calendar as needed.
The same would apply if it were a Google calendar added via Exchange.
If the calendar is not actually on Exchange, but rather added from an outside source, it will depend on that outside source where the calendar originates.

Does iTunes share music only over Network or via Airport across any network

Hello my name is Bill and I am running an unsecure network. There, I got it out and I feel terrible about it. Please read on to see if you can help me.
The other day I was on my iTunes and noticed another user's music folder pop up along the side bar. It said Leyla's Music. I don't know any Leyla. This leads to the question in the Subject line.
Maybe my question is vague so I'll try to clarify. I've just moved to Istanbul and bought a Turkish modem. It will only run its installation CD on a PC. I have an old Windows 98 laptop that I was able to set up the network. However, I am unable to change security settings because my old Windows 98 doesn't have the right font set to read the CD program.
Normally, I have my music on a LaCie connected via USB to my iMac. I then share the music so that I can pull it up anywhere in the house on my Powerbook. How does it physically share the music. In other words, does the user have to be on my network or does airport just broadcast a signal to any iTunes in the area, be that on the same network or a different one?
Differently put, is Leyla poaching on my network or is she just picking up my iTunes signal? I have already added a password to my music but want to know if I need to get a new computer or something else to get this network secured to my MAC addresses only. (oh yeah, I tried to update the WIN98 font set but couldn't find it on microsoft.com)
Thanks for looking,
Bill

I'm having the same issue, but I have recently changed a lot of things. With so many variables I don't know where to start, but maybe we can figure out a common one...
I have 2 individual libraries, one on my Laptop, another (extended library) on an external drive, I changed my DNS to open DNS, I have recently added an Apple TV, added 2 Airport Express and setup 'Simplify Media' to share my library over the internet. Has anyone with the same issue have any of this in common?
I can no longer connect to my iTunes Library via the iPhone Apple Remote, shared through Apple TV or as a shared Library in iTunes.

Can multiple iPhones share the same iTunes account?

My daughter received her first iPhone. She activated it today using my iTunes account and all of my contacts were overwritten with her contacts. How can we fix this? My other daughter received hers today as well but she hasn't activated it yet. What can we do to prevent this from happening? Also, can multiple iPhones share one iTunes account?
Thanks

How can multiple vis share input from a DAQ simutaneously

How can multiple vis share data input from a DAQ simutaneously?
Recently I am building a EMG measurement platform and somehow DAQ data need to be shared by several vis at the same time.
Are there any ideas?

If you may need to add/delete tasks that will need th edata you may want to consider a publich/subscribe pattern. Basically your DAQ task will post a message to a single queue. The process listening on this queue (message broker) will determine if there are other processes registered to receive this message. When a device registers for a message it provides a queue to receive it on. The message broker will then post the message to all interested processes. The nice thing about this pattern is that you have dedicated code to handle broadcasting the message and it is very easy at run time to change the number of processes that get the message. The DAQ task will always send the message and will not care how many processes are listening.
