File Sharing Problem and slow data transfer

Hi,
i just receive my MBP a few weeks ago and i wanted to transfer some data with a friend who has a MacBook. I tried to share a folder and it cold not be seen by the MB as guest login. i checked the permission when i add the folder to the file sharing as read only. Second problem i had is more intriguing...finally a i decide to log in as Me with the MB, and then i saw my folder shared. he copy the stuff he need it with an acceptable speed. He shared a folder to me the same way i tried and it works!! but the more frustrating was to see how slow was the transfer from the MB to my MBP. Can find any explication...any suggestion???? please !!

slowness of wireless transfer speeds could have something to do with your access point/wireless router.... if you have bad bars on your airport card then try moving closer to the signal.
also what is that total size of the files you are trying to move to each laptop?
i remember when i transferred a fair amount of MP3's it did take a little bit of time....

File sharing problems and horror story (nearly)

I use Leopard on a MacBook Pro, a MacBook and a iMac G4 800 MHz (unsupported model).
I have on the iMac and the MacBook Pro many users (the same ont he two machines) and I always use Fast User Switching.
I have had very few problems with Leopard until now; I like it even if there are some glitches or some new features which are not my cup of tea (hierarchical menus missing from the dock, stacks useless when there are many items, FireWall impossibilities (?) to open specific ports, Back to my Mac working on a Lan but not from outside until now, problems with a few apps (Parallels networking erratic), ...
Now about File Sharing.
Let say my main account is user1 (Administrator), and I have another user2 also administrator, plus user3, user4 standard users.
On the iMac I activate File Sharing.
On the MacBookPro, as user1, if I connect to the iMac Server (using afp://IPaddress_of_theiMac/) I do NOT get the dialog
"Enter your user name and password to access file server YYY
Connect to server as Guest or as Registered User"
but I directly get the dialog
"Select the volumes you want to mount on YYY"
From this, if I select user1 it mounts with full read/write permissions which is normal. It appears that I am connected with my Apple account user1&mac.com (same as mentionned in the Account panel of System Preferences).
On the other hand, if I try to connect to the user2 account, I only get limited access although in the File Sharing Preferences, user1/iMac is mentionned with full Read/Write preferences for the Home Folder of user2.
What is very surprising is that if I log on the MacBook Pro as user2, or user 3 or user4, then connect to the iMac, I first get the dialog to enter a user name and a password. This gives me access with the correct full permissions on user1/iMac or user2/iMac using the corresponding user name/password pair; this is the usual behaviour which is missing when trying to connect from user1/MacBook Pro.
Now for the Horror Story!
Trying to understand what was going on with the permissions of the user2/iMac account, I logged in to the iMac as user1, went to the Users folder and from there had a look on the informations about user2 home folder. In the lower part of the pannel, Sharing & Permissions says "You have no access" (which is normal) and this is followed by a table where users and permissions are listed. It seems user1 has Read and Write access in contradiction with the preceding phrase...
Anyway, I tried to modify these authorizations for user2 by clicking on the lock of the Information pannel and entering name and password of the administrator. Didn't go farther than that. By mistake, I hit Command-Delete and user2 was GONE from the list AND NOT ONLY from the list in the Information window! Using Fast User Switching and going to user2, nothing left on the Desktop and NO Home anymore.
In the System Preferences/Accounts panel, user2 was still mentionned.
In the Users folder, no user2 folder anymore.
Using once again Fast User Switching, I logged as user2 and got by magic an all new Home. Nothing left in Documents, Library or other user1 folders. Standard settings for icons, dock, etc.
My first move has been to use a very recent backup to restore everything (Thank you Mike Bombich from Copy Cloner!).
Once everything was back to normal, I had a look at the Trash from user1 and guess what, the Home folder of user2 was there, complete.
So now I am left with two questions
why is it I do not have the same dialogs when connecting from all the accounts although as far as I can see, configurations are the same?
why is it possible, from an Information pannel to delete the account of another user?
Thank you all for comments!

Wireless/airdrop/file sharing problems

Wireless/airdrop/file sharing problems
I operate an IMac 3.06GHz and an Airbook 1.4 GHz
I frequently need to transfer files between the two, and in OSX 10.6, did so by setting the iMac to share the wireless connection and using drop box
This no longer functions in Lion (1.7.1).
Symptoms are:
1. Air drop simply does not function. Neither computer recognizes the other, even if they are adjacent.
2. The Airbook will recognize the wireless connection, and is able to connect with some programs, but not all.
3. For example, Safari is able to load news sites, but not gmail and a google search freezes, although a Bing search for the succeeds.
4. Turning both Firewalls off has no effect
5. Restarting both computers with new settings has no effect
6. Neither machine shows in the sidebar of finder, therefore I am unable to access one from the other directly.
Any ideas or back to Snow Leopard?

Some kind of technical problems (like slow data processing)...

Some kind of technical problems (like slow data processing) with Leopard appears during the working in the local network.
OS Snow Leopard 10.6 is installed; including all updates, the computer I currently use is Mac Pro. So I have some kind of technical problems (like slow data processing) with Leopard during the working in the local network. (Windows network).
During the attempt to connect with network sharing (the computer is in the network) automounter process took approximately one minute.
Later on, after the automounter process is finished it’s working quite normally over remote computer, but when you try to automount again, everything starts from the very beginning.
The internet is working very well, it’s connected with domain, and everything is adjusted.
I use to ask our system administrator; maybe it is necessary to activate the some kind of protocol?
The OS Tiger is installed on the second hard disk, and it’s working well.
Maybe someone could help me, I try to find the similar problems, but I could not find them.
Thanks//

A couple of things.
First, thanks for the tips. I was starting to suspect the network might be an issue (bad nic, bad router, something).
But netstat -s was showing an average of about .15% packet loss. For a web server that seems to be a pretty good value so I'm not sure.
I did, however, ask someone else to look at the server because I'd spent the whole week on just server performance and was going out of my mind. This second pair of eyes really helped as he found that the pagefile for the server was set at 2mb!? Still trying to figure out how that happened. But we increased the pagefile to a much better value. There wasn't an immediate change in performance, but over time the server appears to have begun to respond better.
Occasionally I still get these 'lag spikes' but nowhere near what they were and the delay is much smaller as well, which is probably being caused by something else entirely (like bad programming on my part, hah).

Slow data transfer on Disk images created in Mountain Lion

Hi apple community, since upgrading to OS 10.8, every blank disk image that I create using disk utility, no matter what partition setting I use, results in excrutiatingly slow data transfer speeds. I do not have this problem when I use disk images created on previous operating systems. For some reason it's taking about a minute to transfer 40mb to these folders. Any advice would be greatly appreciated, thanks.

It happens with both sparsebundle and DMG, and I've tried various partition settings, including hard disk, CD/DVD, Apple partition map, as well as no partition map.

10.8 Server file sharing problem

We have a new Mac mini with 10.8 and OS X Server app. The mini has direct attached storage and will be used mainly for File Sharing. There is a repeatable problem/bug with case sensitive folder names and file sharing. For example a folder named "Editorial" is inacessible via "Connect to Server" from a client on the LAN. The same folder with the same permissions, same everthing, except it is named "editorial" works perfectly. Change the uppercase E to a lowercase e and it works. The drive is formatted with normal HFS+. It is Not HFS+ case-sensitive. I have Xserves running 10.4, 10.5, and 10.6 for file sharing and none have this problem.
Has anyone else experieced this? Is there a fix? Other than making everything lowercase.

Simon Slavin United Kingdom
If you have a problem please start a thread of your own. Don't get us confused between solving two different problems.
Simon,
The subject of this thread is dealing with:
"Server 10.8 file sharing problem"
Specifically for direct attached storage file sharing permissions issue.
Client computers having issues with folder permissions
These are exactly my issues as well. I was hoping to try a solution here or maybe proffer a solution if found elsewhere. I did not realize each problem should be opened as a separate discussion....

File sharing problems with my Media Player, an A C Ryan

I have a media player, an A C Ryan, hooked up to my wifi at home and it normally accesses all my hard disks that is plugged and shared on my iMac. I had no problems when the iMac was on Snow Leopard. Under Network/Workgroup in the AC Ryan's menu, I can see and access all the files on the hard disks.
The moment I upgraded to Lion, all such access was lost. The AC Ryan cannot connect to the hard disks any more via the wifi network. it's as though file sharing has stopped completely. I checked the file sharing settings on the iMac and nothing has changed i.e. the disks were shared as usual. After struggling with many possible solutions and failing (I checked out a lot of forums), I reintalled Snow Leopard and the problems were immediately solved.
Is there something seriously wrong with Lion's file-sharing? Has this been fixed in 10.7.2? My friend who has a similar setup (his media player is the WD Live) has exactly the same file sharing problem with Lion.
I would appreciate any feedback. Thanks!

I believe that NTFS-3G has issues with Lion.
I use Paragon NTFS and have had no issues at all. I am pretty sure that NTFS-3G will get updated, but you need to check their site to find out when.

XP to XP slow data transfer - WRT54GP2

I have two XP sp3 machines in my network. Data transfer between them caps at 1Mbps. This is very odd since both machines have tested at speedtest.net at 15M down and 1M up. Why is my network transfer so slow? What can i try.
A little about my network. All cable is new cat 5e. There are 10/100 NIC's in each machine set to auto negotiate. I have tried setting the NIC's to 100 Full Duplex with no success. Both machines have static IP's assigned. All anti-virus and firewalls are off. Both machines are on the same workgroup and can see each other.
Cable modem connects to a Linksys WRT54GP2 router with built in 10/100 switch. I assume it "auto negotiates" since i cannot find a setting for it.
Machine "A" connects from router through a set of Netgear HDX101 Powerline HD Ethernet Adapters then to the machine. I have also tried bypassing the Powerlines and transferring the data over WIFI. I only get up to 1.5 MB/s transfer speed. My WIFI says im getting 54 MB/s. I was hopping to see near 25 MB/s at least.
Machine "B" connects directly to the router via cat 5e.
I also have a MacBook on network too. It's wifi also suffers from the same transfer rate. If the xp-xp fix doesn't also fix the MacBook i will open a new post about it.
I have read ssoooo much about similiar issues to what im having. im really hoping on of you can help. thanks.

The Internet Speed Test and the Data Transfer Speed are the 2 different Things, You Internet Speed is nothing related to your Data Transfer Speed between your Computers. As GV suggested you, connect the Cross Over cable between your computers and assign a Static IP to your both the computers and then transfer the data between your computer and check at what speed the data transfer speed is going on.

How can i improve speed of my application and reduce data transfer time ?

Hello,

Problems with N80 and usb data transfer

data transfer started off working fine (I think) but now the pop-port connection seems really flakey. It keeps dropping the connection and causing transfers to fail on mac and PC. hope it's the cable, but anyone else having this problem?

I'm okay with bluetooth at the moment - I use iSync on the Mac which seems to work okay. File transfer over bluetooth also seem to work okay - just tested with a couple of mp3s. However, I need to use USB for large quantities of data (music, photos, etc) and it doesn't seem to work. I have tried it on both a mac and a pc with the same issue each time.
The symptoms I have are exactly the same as you sysinit - if I touch the device then it seems to disconnect and reconnect rapidly. Unfortunately, even if I leave the device completely untouched and try to transfer 100MB of data, invariably it only gets halfway before conking out!
Most of the other software issues I can deal with (I had a Sony Ericsson P900 before this which had its fair share of problems!), but this to me is a showstopper. If there is no fix for the problem then the handset is going back as the problem is so easy to reproduce.

OS X Server 3.01 Install and File Sharing Problem(s)...

Greetings...Apologies in advance for the lenght of this post...but I wanted to provide as much info as possible to the community to see if someone can see what I may be doing wrong.
My goal: Replace an existing iMac running Mavericks Server v3.01 that I use for Open Directory & file sharing with a new Mac Mini Server (late 2012) running Mavericks Server v3.01. Once new server is working and users defined...I will copy the users data from the iMac to the mac Mini server...then re-purpose the iMac as a simple client (bound to the new Mac Mini server).
Before we get to what I have been trying...I guess I should ask a few basic questions:
Can you have 2 Mavericks servers on the same Local network?
Can you have 2 servers as OD Masters on the same local network?
Are there any "Best Practices" I can follow to set up the new server on a local network that already has a server on it?
Here is what I have tried:
First off...I assign a static IP address to the Mac Mini on the router and disable the WiFi on the mac mini. I am using a direct ethernet cable connection from the mac mini to the router.
Next, I intall Mavericks client and configure that. I download Sever from the App store and install it. After it is installed...I run the "ChangeIp -CheckHostName" command in a terminal window and it reports that the "Names are the same" or something to that effect.
Next up...I turn on Open Directory and set up a OD Master...using essentially all the defaults. I then turn on file sharing and set up a share for the "Users" folder and set that share to use AFP & SMB and to also use it for Home folders.
I then set up a test user as a "Local Network user" and specify that the users home folder is on the "Users" sharepoint.
Once that is done. I logoff the admin account on the server. I then go to my macbook pro and bind it to the server (Users/Login options). I see the server identified as "Mac-Mini.home", select that and it shows a green dot next to the server...which I interpret as it was bound successfully.
I then log in to the newly created network user from newly bound macbook pro. No errors are reported and I seem to be functioning fine. I can use Safari.
As a functional test (lame ... probably) I try to log in from a bound client, save a text text file to the documents folder. Log out as the user on the bound client...Then I log in as that user on the server to see if I can edit/update that same file from thedocuments folder.
However, when I launch the TextEdit app on the bound client, it appears briefly on the Dock...then crashes with a system error. I tried to read the error...but it looks greek to me. I did see something to the effect "operation not permitted...".
I logoff the bound macbook pro. go to the server and log in as that newly created local network user. I get logged in. I am able to launch Text edit when logged in as the user. I can add text...save the test file to the document folder. Everything looks good. I just cannot seem to log in as the user from both the bound client and the server and have it work normally.
So...I am obviously not doing something either in the correct order, or not configuring a service correctly...something I am doing wrong.
Any suggestions are appreciated.

A NAS should work. A proper file server will cache active files in memory. So it's not obvious use of SSD storage will speed your service. In any case figure out how to back it up and most important how you will recover after a disaster requiring full recovery.

File sharing problems with T500 and T410 and a desktop all running XP Pro SP3

Others have had similar problems with what appears to be an overriding of Windows file sharing by Access Connections.
My three computers, printers and internet modem are networked and working fine both wired and wirelessly except that while the desktop computer in network places can "see" shared folders on the Thinkpads, access to them is denied. Access to desktop shared folders from the Thinkpads works fine.
All the usual sharing settings have been checked and verified by Microsoft support; it does not so far have a solution.
Could this issue please be addressed more thoroughly and/or suitable documentation referenced? I have read the blurb about Access Connections but can't make a lot of sense of it.
Thanks

When you use the Desktop top menu bar Go/Connect to Server and enter

Painfully slow data transfer on Airport Extreme (Start and stop over 6 hours for 200 megs)

I've had my airport extreme set up for 2 years with 2 hard drives attached for my files. I have never had a problem with transferring to them until this morning. I have been unable to transfer anything to the drives at all. Every file I have attempted starts, will get about 10% through the transfer (regardless of size) and hang. I left one file "transferring" to see how long it would take - a 183 meg file took over 6 hours!
I have restarted the APE, the drives, the computer and check all connections. Nothing has changed from yesterday to today.
I don't even know where to begin with trying to figure out this issue. Can someone please help?

The new Airport Extremes and Time Capsules suffers from terrible performance over the 5GHz band and it's a problem that not only affects me and you, but hundreds of thousands of other owners.
Nobody knows if it's a firmware problem or the Marvell chips inside that's the problem, and Apple hasn't said or done anything for months.
I'm still hoping for a firmware update to solve this, but if it doesn't get fixed soon enough, I'm gonna return it and go back to backing up to wired disk and my rock solid Airport Express.
Not the happiest answer, but at least you have a clue now.
Cheers,
Koski

File sharing problems between Vista 64 bit and iMac

I have a week-old iMac and am trying to completely network it with my wife's new Windows Vista 64 bit Dell Studio laptop. Everything seems to be working correctly with the exception of not being able to directly log into the iMac from the laptop even though the iMac is visible in the Windows Vista Network screen. File sharing is turned on with all user accounts active. Both computers are visible on the network. The Vista laptop has Windows firewall turned off and McAfee Security Center firewall turned on.
Help and suggestions are appreciated.
Thanks!

That is an excellent reference! Just another reason why Vista is trash.

Screen and file sharing problem

I can connect from my MacBook Pro to my iMac when they are both on my home network. I see it in the Finder sidebar, clicking it automatically connects to its shares, and clicking Share screen does what it's supposed to do.
But when I try to connect from the MacBook Pro from the outside world (my company's network) things don't work so well. I have Back to my Mac enabled so the iMac still shows up in the sidebar but when I click on it I eventually get an error message "Connection failed". Clicking on Connect as does nothing. Clicking on Share screen gives a generic error message.
When I connect to the iMac using "Connect to server" (Command+K) it works. I have mapped the AFP and VNC ports of my Airport Extreme base station at home so they point to the iMac.
What can I do to fix this?

I'm sure you've already checked, but have you given user access to the mini via it's sharing prefpane? Not that this will fix it - I currently have five separate macs running leopard, all with file sharing for a specific folder and guest access to those folders and it only works on 3 out of the 5 (the two that aren't working are MacPros - go figure).
