Does a high number of user accounts (e.g. 7) slow the computer down?

Mavericks 10.9.5, 3.5 GHz Intel Core i7, 16GB 1600 MHz DDR3

What was stated isn't completely accurate.
If you have seven users sharing one computer and all of them are filling up the Mac's hard drive with data, once the hard drive is nearing full (15 GBs OR less), then all of the users of this Mac will start seeing slow downs when they are using it.
If you are using that many users on one Mac, it would be best if you purchase a high capacity storage, (say 3 TBs or even larger, if you can afford it) fast transfer protocol (USB 3.0, Thunderbolt or FIreWire 800 connections) externally connected hard drive and partition it and have every user setup to store their data the external hard drive, instead. This leaves the hard drive inside the Mac relatively free of everyone's data and will keep it running much faster for a longer period of time as you won't run out of internal hard drive storage space as quickly.

Flash player does not work under one user account.

Flash player does not work under one of my user accounts.
My system: I work with a mac mini with Mac OS X 10.6.8.
What I have done:
I installed the flash player maybe one year ago under my "first" user account. At that time this user account had had administrator authorization. In the meantime I had to change this "first" user account in an account without administrator authorization and created an administrator user with which I installed different programms. Lately, the message came up that it would be necessary to update the flash player. I did it; under the "first" user account, but of course with the administrator's password for installing. The installation had been "successful" - so I was told. But it did not run. I tried it again and again. Each time with "deinstallation" first. No way; it did not work.
After asking Adobe for the reason of the problem, they suggested to install the programm directly under the administrator user. I did that (of course after deinstalling under the "first" user account) with the result, that flash player runs under my administrator and my "second" user account, but not under the first user account. There I am always told to update my flash player.
With this result, I talked to Adobe. So they told me to contact the producer of the operating software, since this would be a mistake of the operating software.
And here I am - full of hope to get help from you.
Thanks for reading. And thanks in advance for helping me.

Any update to provide at all here guys? Again, in my situation, it's very much rights-related as a standard user doesn't even report that the flash player exists when testing it on the Adobe Flash Version Detection website (despite it showing up in Control Panel and under Add/Remove Programs). I've already tried giving the C:\Windows\System32\Macromed and files/subfolders appropriate permissions for the standard user and still nothing. If I either give the user in question full local admin rights or logon as the domain admin, then the Adobe Flash Version Detection website says Flash is installed and Flash works fine.
Thoughts???

ITunes does not launch with new User Account (Vista)

One of my limited user accounts on Windows Vista because corrupt, so I created a new limited User Account and copied ALL of the files from the old to new.
Now, when I try to launch itunes on the new user account, it will not open at all. Itunes works on my administrative account, with no problem.
Can someone tell me the most pain-free way to resolve this issue. And, whatever solution, will I be at risk of losing my itunes libraries?
Thank you in advance.

Hiya. Delayed again. Browsers being cranky. (I blame the aftershocks.)
It's actually plausible that it was installed in there (by doing a run as administrator on the installer itunes64setup.exe, perhaps). Because that suggests a possible cause for these continual permissions-related problems.
A lot of what you're seeing is consistent with damaged ACLs (access control lists) on files, folders and registry keys. Although it's a lot rarer than it used to be, one of the ways you could get borked ACLs was if a program (like iTunes or QuickTime) was installed in one user account, and then the user account it had been installed in was deleted (or otherwise rendered unusable).
We don't know which particular permissions are stuffed up here. But there's a shotgun approach to fixing them which used to work okay, although it's a bit fiddlier to do on a 64-bit system than a 32-bit system.
I'd strongly recommend setting up a system restore point prior to doing this, so you can revert if things turn to custard.
The basic technique you follow is from the following blog entry *with one important modification.*
[Solving setup errors by using the SubInACL tool to repair file and registry permissions|http://blogs.msdn.com/b/astebner/archive/2006/09/04/solving-setup-e rrors-by-using-the-subinacl-tool-to-repair-file-and-registry-permissions.aspx]
The modification is that when you're editing the file to replace YOURUSERNAME with the name of the account, edit the first line so that %ProgramFiles% instead says %ProgramFiles(x86)% and after the line that reads:
*subinacl /subdirectories %programfiles%\ /grant=administrators=f /grant=system=f /grant=users=e >> %temp%\subinacl_output.txt*
... add another line saying:
*subinacl /subdirectories %programfiles(x86)%\ /grant=administrators=f /grant=system=f /grant=users=e >> %temp%\subinacl_output.txt*
(The first is to make sure the commands see the subinacl, because it installs in \Program Files (x86)\ on 64-bit systems, and the second alteration is to make sure that the permissions for the 32-bit program files are fixed too.
After doing that (it'll take a while to run), can itunes launch normally in the new account?

Hello Renvin29,
It sounds like you need to disable your iPhone remotely. I'm sorry to hear about your phone! The only way to do this with is Apple services is if you had Find my iPhone enabled. You have 2 options:
You can use this article to put the phone into Lost Mode and preserve your data on it, but prevent access to it:
iCloud: Use Lost Mode
http://support.apple.com/kb/PH2700
Or you can just erase it remotely outright:
iCloud: Erase your device
http://support.apple.com/kb/PH2701
You should also take a look at this article for additional info on what to do about this situation:
If your iPhone, iPad, or iPod touch is lost or stolen

Welcome to the Apple Community.
Unfortunately once all the 3 iCloud accounts have been created on your device, you cannot create any more regardless of what you do. You will need to re-use one of the accounts that you have already created or create your new account on another iOS device or Mac computer.

In Windows 7, Microsoft updated UAC in several ways. By default, UAC does not prompt when certain programs included with Windows make changes requiring elevated permissions. Other programs still trigger a UAC prompt. The strictness of UAC can be changed to either always prompt, or to never do so.

New to the Apple and I want to set up a user account that will not delete the guest users files and allow and preserve their personal settings after log out. Is this possible?

New to the Apple and I want to set up a user account that will not delete the guest users files and allow and preserve their personal settings after log out. Is this possible?

The built-in guest user account will not do this. Simply create a new standard account and call it "Guest" or "Guest Users" or whatever you like.
Go to System Preferences > Users& Groups, click "+" to make a new account.

If you lose your phone and you get a replacement . does you imei number change? or do they keep it the same as your old one?

if you lose your phone and you get a replacement . does you imei number change? or do they keep it the same as your old one?

Hi
Every handset has a unique series of identifiers, one of which is the IMEI number, so if you exchanged the handset (for example if it was not working & you were still under warranty) your new handset would have a new IMEI number.
What Apple do though is if you formally exchange your handset (again, under warranty etc) then they record the change on their system, but also give you a sticker which is meant to attach to the original box. That way, if you come to sell the handset, you have a proper record of why the IMEI number on the handset is different from the IMEI number on the box.

On Maverick my i cloud will not change the verification phone number even though I have change the phone number in apple and on contacts and restarted the computer. Help? I can't get the code necessary to fix the keychain.

On Maverick my i cloud will not change the verification phone number even though I have change the phone number in apple and on contacts and restarted the computer. Help? I can't get the code necessary to fix the keychain without it.

You can change the phone number the verification code is sent to from a device or Mac that has your iCloud keychain enabled as follows:
In iOS 8, tap Settings > iCloud > Keychain > Advanced. In iOS 7, tap Settings > iCloud > Account > Keychain. Make sure the phone number under Verification Number is correct. If not, enter another phone number.
In OS X Mavericks v10.9, choose Apple () > System Preferences. Click iCloud, then click Account Details. Make sure the phone number under Verification number is correct. If not, enter another phone number.
If you don't have access to a device or Mac with your iCloud keychain enabled, you'll have to contact Apple support to verify your identity and get assistance making the change: http://www.apple.com/support/icloud/contact/.

HT4623 so I am updating my phone to the newest IOS and it has been doing it for hours. I have now plugged it into the computer and it says that it is in recover mode and I should restore it? What does that mean? Do I lose everything on my phone?

Have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds, after which the Apple logo should appear - you won't lose any content, it's the equivalent of a reboot.

Is there a limit in the number of user accounts on Mavericks?

Hi
I would like to create a system with a lot of user accounts (+/- 200).
I have two questions:
- Is there a limit in the user accounts on Mavericks? Where can I find more infomation about this?
- Is there a possibility to automatically create a high number of accounts? Or at least some sort of template?
Huge thanks for any help.

I don't think that there is a limit.

In many organizations, a single shared directory domain is adequate. It can handle hundreds of thousands of users and thousands of computers sharing the same resources, such as printer queues, share points for home directories, share points for applications, and share points for documents.

TS3276 There are two User accounts on my iMac. The two Users have seperate email accounts. Both email Mailboxes show up in each Account. If I Delete Mailbox from in User account, does it delete the Mailbox from the other User account at the same time?

There are 2 Users on my iMac. Each User has their own email account. Both account Mailboxes show up in each User's account. If I delete a Mailbox in one account, does it delete the same Mailbox in the other Account?

If you click the - sign in Mail preferences, it will delete that mail account. If you just delete the Mailbox, that will just delete the Mailbox.
Each user can put their own email account information in Mail when logged into their User Account.
If you don't want the other user's mail account to show up in your mail application, then make sure the other user's messages are available to them when they are logged into their account and delete the other user account from Mail in your User Account. The other user can do the same when logged into their user account. Any messages stored in one locally will have to be transfered to the other's user account if it's not saved in their user login.
In addition, instead of deleting the account at first, highlight the account and open the Advanced Tab and disable the account. That email account will dissappear from Mail. Once you decide that you don't want the account, you can delete it. If you need to get back to it to transfer messages, just re enable it.

How to change the thread number for user account

I remember that for each user account, we can limit the maximum thread number it can create for a user process. But how to change this number?
Thanks,
Iris

Hi ,
I do not think that there is a way to control the number of "threads per user".
Are you referring to "thread id" ? Please elaborate on your requirement.

ITunes does not open in 1 user account

IiTunes says it's not compatible with this version of OS, in 1 user account and not in the others. Same thing in iPhoto. Please help.

Login to that user's account. Then do a Spotlight Search for "iTunes". Open it up from there. If it works, then that is the iTunes you want to use.
To find that working iTunes, do a Spotlight Search again... Once the iTunes app is selected automatically (don't click on it), press on the command button, that will show you the path in which that iTunes is located. Then you can find it for yourself and correct the problem.
