Finder freeze while copying over network

i have two mac on a network at home, both are now with 10.4.11 - but ever since i updated to this system version i am having a problem with the laptop. whenever i copy a file over the network from the desktop to the laptop, the laptop's finder freezes for the duration of the transfer - i can't open other apps, can't access anything else. the status bar of the copy doesn't change. if another app is open before the copy starts, it works fine. mouse works fine.
i can't figure out why this is happening... any clues?

Same problem here, I think: Finder hangs (beachball & Not Resopnding in activity Monitor) during file copy then comes back when copy finishes. Hang starts when I click in the finder to view another directory on the remote machine. When copy is done on PowerBook via Airport, Finder hangs. 100 Mb/s ethernet stutters but does not hang up, but 10Mb/s hangs up.
Same issue on this thread in Feb: http://discussions.apple.com/thread.jspa?messageID=6299419&#6299419
Some things I've tried to no avail:
Fixed Permissions.
New user does the same.
Reinstall 10.4.11.
Etehrnet 100Mb/s - No freeze, but finder still jerky.
Ethernet 10Mb/s and Airport 802.11g hang.
Other mac, wireless to laptop - ok.
Used file appleairports2.kext from 10.4.9, no help.
Deleted Finder.plist, no help.
Re-reinstall 10.4.11
Tried airport with no security settings
Trashed recent servers file.
When airport is faster, finder works slightly better, clearing freeze occasionally.
Activity monitor Finder not responding, sampling does not clear freeze.
I think it is interesting that Finder does better with higher data transfer rates. In fact, the problem is evident on an ethernet connection when I slow it down to 10 Mb/s, OK at 100. So it may be purely a Finder problem.
What I have not tried is going back to 10.4.9 nor a clean install of 10.4.11.
Has anyone figured this one out yet?
Thanks to UltraSoul for clear postings on this.

Finder Freeze while copying files

Hi,
Recently my Finder freezes whenever I transfer big files (more than 1 gig) to my server through network. The Finder would freeze for 10 to 20 seconds and the copying bar freezes too. After 10 to 20 seconds, the copying bar continue to copy the remaining and the Finder back to normal. I am using Mac OS X 10.6.7. I have formatted and install the Snow Leopard installation disc and it seems ok but after I upgrade to 10.6.7. The problem comes back. Please share if there is any solution. Thanks.

Can you try FTP. It is a just try and narrow your problems. Also can you access via a browser. I take it that they are mounted on a router, which one. Finally, are you having problems with smaller files on both AFP and SMB.

Finder Freezes when Mounting over Network

I have a network set up and can see the computer I want to access in Network. When clicking to log into the computer, it asks for username/password as usual. Then it asks me what drives I want to mount, so I select the one I want and then a box comes up saying mounting, with a progression bar, but it just sits there and never mounts. The box remains in the foreground so to get rid of it I have to restart the computer. I really want to be able to access the drive over the network. Any ideas?

Hi Phil, and a warm welcome to the forums!
One thing to check...
In finder, select Go menu>Go to Folder, and go to "/volumes".
Volumes is where an alias to your hard drive ("/" at boot) is placed at startup, and where all the "mount points" for auxiliary drives are created for you to access them. This folder is normally hidden from view.
Drives with an extra 1 on the end have a side-effect of mounting a drive with the same name as the system already think exists. Try trashing the duplicates with a 1, and reboot.
You may also have to trash this file & reboot...
/Users/YourUserName/Library/Preferences/com.apple.recentitems.plist
Also, once you do get them to mount...
Mount that Share once, then once the Globe Icon shows up on the Desktop, drag that Globe Icon to the right side of the Dock between Applications & Trash. You now have a Dynamic Mount, a quick click on the Icon in the Dock will connect you.
On the multiple Shortcuts...
Mount them all, when show up on the Desktop, then create a new Folder maybe named Shares on/in the Desktop, drag all those Shares shown on the Desktop to that Folder, (you can even rename them once there, if you wish), drag that Folder to the right side of the Dock between Applications & Trash, this should give you a popup menu to select from.:-)

Missing files when copying over network

I've had a good search for people with similar problems on Discussions, and there are a few mentions of similar occurences. Here's my summary though.
I have 2 Macs, and frequently transfer files from one to the other by sharing drives and using the Finder.
However, quite often, when transferring lots of files, they are sucessfully copied but do not show in Finder on the receiving machine. The files are there (using Terminal to explore the directory reveals the files in question), but Finder just doesn't acknowledge any existence of the "missing" files.
This problem can usually be cured by creating a new folder in one of the affected folders - this somehow kicks Finder into refreshing the folder's contents.
Removing the .DS_Store file(s) (again, via Terminal) in the copied folder also resolves this issue, leading me to believe that the problem lies with the .DS_Store files.
I cannot believe I am not the only user who frequently finds themselves having to do uneccesary Terminal work to reveal files which appear to be missing after copy over the network.
Is Apple aware of this problem? Does anyone else have any workarounds?

I don't think I have experienced that exact problem however, I am such a Unix geek, I typically do my in-network transfers between Mac machines using SCP at the shell prompt in Terminal.
Finder refresh on the other hand I have experienced before although I cannot provide a situation or example.
Usually if it needs a refresh, I believe all I ever do is navigate away from the folder, then back to it. Or if it is the Desktop in question, using Exposé to show it, a single click on an empty space there will make the newly copied items appear.

Finder freezes when copying files to an external USB drive

I am copying video TS folders from my Mac Pro to a USB 3.0 drive, and Finder keeps freezing up. Oddly, it doesn't always happen, and it doesn't seem to be the amount of data--I've successfully copied 32GB at once, and had Finder crash trying to copy 6GB. Other details: the external drive is brand-new, and set up for OS X, I have repaired the permissions on the Mac's drive and just for kicks did the same on the Seagate USB drive. I was originally copying the files from a folder I had on the desktop, and read here that the desktop being involved in the equation is a Finder-killer, so I moved the files to a different folder. I have done this a lot in the past to a different drive with no problems whatsoever. Lastly, when this happens, all I can do a hard restart. Everything is fine when it starts back up, but after a dozen restarts in a day, I'm about to shoot myself.

Well, I can tell you this
Mac's can't use USB 3 so it's dropping to USB 2
If it's port powered, it could be drawing too much power and the Mac is cutting it off, use a powered USB hub.
If the external drive is formatted MBR with FAT32 (MSDOS) then that's a issue with over 4GB sized files, you need exFAT or HFS+
You may nee dot remove all data and Zero Erase the entire drive to map off bad sectors and before each time you copy a huge amount of data (if it hasn't ben done in the last 6 months) this catches new failing sectors.

Slow copying over network

I seem to have a major issue here. I upgraded to Leopard today using a fresh install on a wiped hard drive (I prefer it this way - I'm old fashioned ). Everything is going OK, apart from a few hiccups. One of those is to do with copying files off a network server.
I backed up all my files from my Mac Pro (totaling around 80GB) to my NAS Server (until now very reliable FreeNAS x86 box) over 100MBit Ethernet. In TIGER everything wokred dandy in both directions and the server worked fine. In Leopard it's a different story.
Over either NFS or SMB connections browsing a folder is ice-age slow, and often folder displays just fail to finish drawing. I've locked the Finder solid at least twice doing this (a feat considering AutoFS is supposed to stop it happening!). When I try to copy a folder of files it takes a very long time to collect up the files it needs, pausing often for several seconds every so often during the operation, then it starts to copy at a very slow rate, something like less than 2MB/s. It keeps pausing when it's copying and has on several occasions stopped altogether and the share has spontaneously disconnected and timed out. Copying has also locked the Finder solid on one occasion, and on several others I couldn't get the 'Copying' dialog to close at all.
Using AFP the connection is stable and works fine, browsing is instant, when you go to copy counting up the files still has a few sub-1 sec pauses, but copying is still ice-age slow. As a rough idea it's still sub-3MB/s.
This is a huge issue for me as I have all my data on the server and need to get i back in, ut every time I try to copy something I have to leave it for hours. As a good gauge, a 20GB pile of movies took about 5 hours to copy. According to my math it should have taken less than an hour. A 100MBit LAN connection should, in ideal circumstances, be shifting over 20GB of data an hour on a continuous copy operation. Mine barely manages 4-5GB.
I tried pinging the server and got a 0.2-0.3 ms response. I don't get any horrific packet loss (non at all in fact). Nothing has changed on the network since I backed up from Tiger. Again, I've been using the Mac Pro with this server and 10.4 for months copying to and from and it's been faultless.
Extremely frustrated. Hope someone can help!

After installation of Leopard I did have a lot of problems with reduced speed transferring files to and from other Macs on my network as well as to and from my Airport disk. All the way down to 0.5 MB/sec
Leopard sets AppleTalk to be active as default. Turn off AppleTalk in network setup and you will hopefully see a significant increase in speed on file transfers. I am back to 5-7 MB/sec to and from my Airport disk, which is okay.

Faster copy over network? [Solved] Use Linux!

I'm wondering if there is a different way to copy files over a network that would be faster.
I'm running an updated version of ArchLinux, no gui, just command line.
I have samba working to see windows shares and have mounted a share.
I use "cp" to copy a file from the win98 share to my local harddrive. The file is about 670 megs. Every thing works great.
It takes 5 min 40 seconds to copy.
When I copy the same file using "copy" from a win98 computer it's done in just under 4 min.
Any suggestions?
smbmount //comp_lab_server/admin /mnt/winshare
cp /mnt/winshare/images/admin.zip /mnt/localdrive/admin.zip

jerem wrote:If I correctly understood what you exactly did, I would **guess** that :
Yes, not real clear, I wrote this real fast before running out the door...
jerem wrote:
* using cp : the copy uses the smbfs module in the kernel to retrieve the file from the win98 server.
* using copy : well, linux running samba is known to be generally faster than native windows services...
generally faster... that's what I was looking for, but it just seams quite a bit slower
jerem wrote:
The two methods have different results because the copy goes through different processes, different layers, on different systems.
Using smbfs apparently involves some overhead(given your figures).
ok, that helps, I was just making sure I wasn't missing some other great tool that was known to copy files faster.

nope, same computers (dual booting), same disks..
Thanks for you help!

ITunes freezes while copying to iPod

I seem to have suddenly developed a problem with iTunes freezing whenever I try to copy individual songs or whole playlists to my iPod. I have taken the iPod to a local Apple store and it checked out OK, but iTunes still freezes ...... maybe, this relates to the other postings here about problems with the latest iTunes version?
What I would like to do is reinstall iTunes, but I do not know how to uninstall first (I am not at all familiar with how this works in the Mac environment since for the 1.5 yrs I've had my G5 I've never had ANY software issues!). Any help would be appreciated!

I have downloaded the latest version of iTunes from Apple's site and installed it, but it still freezes when trying to copy to my iPod.
I would really love to perform a complete uninstall of iTunes and reinstall the latest version, but how do I uninstall iTunes???

Finder crashes while copying many files.

Upgraded to 10.7 (Lion) and trying to copy about 300 GB of files from 1 external drive to another external drive and Finder continues to crash.
I've tried copying smaller chunks and it works fine up to about 9 GB, when it seems to crash.. forcing me to restart the copy process.
Is there a limit to the amount of data that I can copy in a single batch?

I rountinely backup large chunks of data from my Mac Pro to two external OWC VoyagerQ Firewire hard drives (800). When I say large I mean anywhere from 50GBs to 500GBs at a time. Under 10.2-10.6 I could start one copy and then the second, simple Finder copies mind you, and after the interminable file counting BOTH copies would proceed SIMULTANEOUSLY. Made it as simple as pie to walk away and come back knowing my data was now in three places.
Under LION the same process has become hopeless. Following the same procedures above now results in the FIRST copy having to complete BEFORE the SECOND copy can commence. Are you kidding me? A doubling of the time I have to spend backing things up? Before Apple faults my setup or something, I have five VoyagerQs and three FireWire 800 ports, and have tried the two backup drives chained, on separate FW channels, even with one inernal and one external and the same thing happens. I suspect that this is related to Thunder^^^^ and is something APPLE has got to fix fast or a lot of folks are going back to 10.6. Be interesting to see how the Mothership responds. Kill the messenger is most likely.

Windows 7 64-bit cannot find HP C5280 printer over network

I've had this working under the same conditions for several years, same computers, same printer, same network configuration. One day, my computer stopped being able to print to the network computer, coming back with errors. I uninstalled the printer and when I went to reinstall, it cannot locate the printer at all. Everyone else on the network can see and use the printer, I can see and access the computer that it's plugged into, but going through the add a printer wizard, even specifically going into that computer manually, it sees no printer.
I've run through the Microsoft Fixit, no results. I've run through the HP Network Troubleshooter, no results. I've rebooted all computers in question, no results. It's not a networking problem, as I said, because I can fully access every other computer on the network. The printer has been verified as shared and operable from every other computer on the network.
Ideas? Thanks.

Check that printer sharing is still enabled on the host computer. If it is, let's delete and re-add the printer on the host PC:
1. Unplug the printer's USB cable.
2. Go to Start > Control Panel > Devices and Printers and delete all instances of the printer.
3. Plug the printer USB cable back in and wait for the PC to re-add it.
4. Once it is re-added, right click the printer and enable/setup Printer Sharing.
Try again from the ohter PC(s).

Playing footage over network - slow down after a while

Hi everybody, I have ProRes422 footage I work with stored on network. We bought a 12TB NAS and I found, that when I play the edited movie from timeline, it freezes after a while (2-5 minutes) - it seems to me there is some kind of network overload so that the data cannot be transferred fast enough to continue playback. I thought it is problem of the NAS, but I tried to read the footage from external HDD over network and the problem is the same. Would any of you have an idea how to fix this?
Thanks

For users like you who insist on ignoring the warnings and still want to buy cheap, I offer this alternative:
Buy Local Attached Storage, RAID 5, for each work station, a gigabit Ethernet switch, and CAT6 Ethernet cabling.
These days, you can buy 8TB of RAID 5 storage, including the RAID card, for less than $4,000US. The Ethernet6 switch is about $50US and the cabling is cheap.
Buy twice the storage as you think you need, then make file copies via the gigabit Ethernet network of all files on the storage on each computer onto the storage on the other computer. Now, you are maintaining a continuous back up of all data, which is a bonus benefit.
The real benefit, though, is speed. Modern RAID 5 storage systems achieve throughput in excess of 600 MB/sec, far more than 23 MB/sec.
Your investment in new equipment will be far less than buying a SAN.

HT4527 When transferring iTunes from old computer to new computer, even though all of songs were copied over, not all of them went to iTunes, some appear to be stored elsewhere. How can I find these songs, and how do I transfer them to iTunes?

When transferring iTunes from old computer to new computer, all my songs were copied over, but not all of them were stored in iTunes. It appears they are on the computer somewhere, but not on iTunes. Where are these other songs likely to be, and how can I get them onto iTunes? Because of this problem, Apple will not allow me to update my iPhone.

You may/must have had music files stored outside of your iTunes library.
I'd recommend going to the Finder and then via the search box look for files with mp3 aif m4a aac etc. depending on the music format your digital music had. With the list of files shown you should be able to learn which files were stored outside of your music > itunes folder
Chances are they could be burried somewhere under your documents, downloads, desktop, ... we all have different storage and organization habits.
Then when you find the missing files, on the new computer you can do add to library and go to the folder on the other computer where the missing files are - if your systems are networked - or sneak them over using a USB thumb drive or portable hard drive if you have lots of files, or if you like to have an extra backup of that music, copy to optical disc.

TC freezes while starting - Network adapter damaged?!

Hello everyone,
I have a TC 1TB, which worked fine a couple of month. Unfortunately, since yesterday, TC doesn't work at all, as it seems to be unable to start. From one minute to the other TC didn't appear in my Finder, TC showed a yellow light (not flashing). I tried to restart, since then, the following repeats after every restart (including those after resetting):
TC shows a "yellow light" => shut down the TC, disconnected any cables and start again; then, shortly after showing a "green light", the light starts flashing and than continues in yellow. After a few seconds, yellow light starts flashing, TC seems to restart, ten seconds later the green light appears, followed by the same flashing and continuing in yellow.... All along, TC's drive is running.
The Airport software recognizes my TC as soon as the green light appears, but cannot conntect because in the meantime, TC shows up with a yellow light and so on and on....
I tried to restart several times, including different types of resetting the TC (pushing the button while TC is running as well as when connecting to power).
Can anyone solve this?
I do not think that my TC is dead (unlike many other postings....), because I still can start it. Anyway, I can't connect to it, neither wireless nor directly via ethernet cable....

Hi!
I already tried this - but it did not help. Right now I am writing this lines while looking a streamed video from my iMac. You may ask, why it works - it's easy: I plugged on my old AVM Fritzbox 3070.
I will try this for another hour, but I guess that one thing is sure right now: the TimeCapsule is the problem, not any of my Macs or programs.
Well - and I decided one more thing: my Fritzbox doesn't work "apple-like" using "Back to my Mac". Sometimes I need this feature. So I decided to order an AirportExtreme today. It will arrive here in the next 3 days, so I can try this next Monday.
The TimeCapsule is very slow doing updates - so I never really liked it. Well - if the Fritzbox and the new Airport does a better job, the switch will be perfect.
Anybody out there interested in a nice TimeCapsule 500 ?
*EDIT - it does NOT work :,-(*
Well - my Fritzbox worked for 15 Minutes and now the Videostreaming freezed. BUT - the network does not freeze like it does using the TimeCapsule. However - I am really interested in the AirPort Extreme and if it will make a better job.
My "last idea": The TimeCapsule and the Fritzbox are both about 2 or 3 years old. Maybe the network-standard isn't fast enough for high quality video and causes a crash after a few minutes.

My JPEGS are no longer being copied over to Finder. Only a random fraction are copied. It use to work perfect. Is there a bug in the updated versions of iPhoto?

My JPEGS are no longer being copied over to Finder. Only a random fraction are copied. It use to work perfect. I can move them 4 or 5 at a time, but it is very time consuming. Is there a bug in the updated versions of iPhoto?

OK - here is what I've done in the past. As I want to be able to save my photos on a DVD that can be read by both a PC and a Mac, I am burning them in Finder. I start by downloading into IPhoto. I'll flag and edit the ones I want to print or post to the web. After that I want to take all the keepers and move them from IPhoto to various files I create in the document section of Finder. I've done it both ways in the past, copy and paste or just drag over, all the files would transfer over. Now there may be dozens of pictures that do not move over - very random, in one case there were only 6 photos and the 3 vertical ones did not copy over.
I'm wondering if this is a software issue or if there is just too much data being moved around. FYI there are 2 Nikon cameras I use and the files from both do this.
Thanks

Finder freezes after multiple file copy

Hi! I recently bought an external hard disk drive (1TB) and had it formatted for use of the Mac. I copied all the files in my All Images folder to the HDD by selecting all the files and dragging to the HDD. However, it seems to have copied/duplicated the files in the same folder. Now Finder freezes (the rainbow pinwheel keeps appearing). I am still able to do some keyboard shortcut functions -- to shut down and restart only. I tried to open in safe mode and go to Finder's Go tab but couldn't find the Libraries folder so that I could delete com.apple.finder.plist (I googled this solution). Help please.

I figured it out, it's so bizzare. I realized that for all of the problems I was having, the hang up occured right before the computer was supposed to play a sound. Anyway, I looked through my sound preferences and discovered my alerts were set to go to my jawbone headset, which I only connected to my computer a couple of times, but that was months ago. Anyway, I changed that and all seems well now. All I can assume is that the OS sees the sound is supposed to go to the headset, sees the headset isn't active (or connected), so it tries to connect and activate (which it hangs the app for), and that times out, at which point it routes the sound through the system speakers. This issue is probably uncommon, but doesn't seem to be anything unfixable.
