Mac Pro Dragging/Locking Up During File Downloading??

Within the past week I have been experiencing a problem with my Mac Pro where it drags/locks up and delays anytime I am downloading something. For example if I am downloading something it may take me several times pushing a key when typing to get it to show up or having to click an item or button several times to get a response or for it to work. This applies in all areas or anything I try to do it is not specific to any software. This only happens when downloading though... The files are being saved to an external hard drive so there isn't a problem with hard drive space. The moment everything is downloading everything is back to normal. I have also noticed that this also happens when uploading as well??
I have had this mac pro for about a year and half never experienced this problem before... The specs for it are 4GB RAM & 2 X 3 GHz Dual Core Processor
Any ideas or suggestions?? Any help is greatly appreciated!! I have already tried running repair disk permissions & IceClean and neither of them corrected the problem??

Replace and repair the external drive (might want to research make/model and compatibility).

My mac pro is locked how to unlock?

Locked how exactly?
If you mean the drive is locked then see:
Fix Permissions for a Locked Drive
Open Terminal in the Utilities folder. Paste the following at the prompt. Press RETURN after each. The first command will prompt for you to enter your admin password. It will not be echoed to the screen. After entering your password press RETURN again.
sudo chflags 0 /volumes/*
sudo chmod a+rx /volumes/*
killall finder
An alternative is to download BatChmod and use it to fix the permissions.

Mac Pro Can't write temporary files to 10.4 Server?

We run a file server on an old G4 tower to a network of about 8 Macs. We are having problems with our first Intel machine. We have a 3ghz Mac pro that appears to work fine except for one problem. The server doesn't allow the Mac pro to automatically write temporary files. This is a problem since we are a design firm and we use indesign for a majority of our projects. Without this temporary file users can access the same file at the same time. This is a major problem!
Sever is running the latest version of 10.4
Mac pro is running the latest version of 10.4 as well
I also ran a test where I logged in from the Mac pro to one of our G5s. Indesign functioned normal in that situation.
Anyone have any suggestions?

By looking at your post i have several questions to ask :
Where are the temporary files stored ?
Which data sharing scheme are you using for them ? AFP with POSIX or ACL behaviors, something Indesign uses ?
Which versions of indesign are you using ? Some differences exists in between PPC installs and Universal install and may play havoc with that.
There might as well be the question of ownership and rights that may differ as mentionned above in between your G5 workgroup and the MacPro.

Going into my hard drive causes mac pro to lock up like fort knox

Hi, I have been a mac user for just a hair over a year.(Apple will not help me with anything)
All has been swell until now.
If I go into my hard drive my computer locks right up. I can do
nothing to move it along. The only option I have is to hold down the
power button for six seconds, which kills me and the computer a little
each time. I booted up the computer using the mac install disc and I
used disk utility to "repair" the disk. It reported the disk was "OK".
I thought swell, and went into documents on the hard disk and it
locked my computer up again. I let it sit there for an hour and
nothing moved. apple/option/esc does not do anything. I went into time machine and
went to the documents there and it locked up the computer too. I went into finder and went to documents and it locked up the computer. I went into other areas of the hard drive and it locked up the computer. The funny thing is I can go on the internet, use programs, read email, and everything works fine. Can anyone guide me in
the right direction in solving this problem I am facing?

Sounds like itneeds some good basic maintenance and troubleshooting. Stop using this drive. Start trashing temp files, and off loading good files.
Everytime you freeze and do a hard restart, the chance that the journal, directory, file system and data are compromised increases, in spite of the "OKAY" from Disk Utility's repair routines it is not reliable. And leads to false sense of security. Disk Utility only checks the basic directory, not the files themselves.
It may be something like a damaged Finder plist/preference, or worse, but either you look for an easy fix, or just start cleaning up and moving files and system to a good drive and system.
You may have bad blocks on your drive causing all this. Or not. TechTool can detect bad sectors, but not map them out. (Deluxe is part of AppleCare; or Pro, commercial version).
Start using SuperDuper if you don't already, and Disk Warrior, premiere for disk repairs.
http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html
What you need to be doing is rebuild your system from the foundation up.
You may need to check out Data Rescue II demo from Prosoft Engineering to recover files.
I would begin by installing OS X on another drive, or restoring from TimeMachine. Create/name an "emergency" boot drive partition. Doesn't need to be that large. Keep it handy just for doing repairs and maintenance. Keep another as a clone of your working system and backup - in addition to TimeMachine.
You may want to start by erasing the drive (not just the OS volume) with a 7-way write (not just zero all, it does NOT do a reliable safe job mapping out bad blocks) and restore from TimeMachine. Or work with a new drive.

The old win 7 x64 on a mac pro 1.1 issue - ISO file unreadable/corrupt

Hi all,
Trying to install win 7 x 64 on my mac pro 2,66 xeon 1.1. I knew beforehand there were issues, so I had prepared for them with the instructions given by flickguy here:
http://discussions.apple.com/thread.jspa?threadID=2207855
thing is, the resulting ISO file is unreadable in windows XP, is being seen as corrupt / unable to open by winrar , and the burnt DVD is shown as blank in snow leopard with all the latest updates.
I'm a bit clueless now as i have no idea at all what the problem is. if anyone has found or knows a solution to this, i'd be very grateful.
Thanks!

Mac Pro Ports cycling power during sleep - waking up drives

If I try to sleep my Mac Pro 6,1 under Yosemite, everything powers down as expected, I’ve even successfully used ‘Jettison’ to eject the USB drives on the first sleep power down. However, the Mac then powers its ports back up, awaking the USB and Thunderbolt drives, and other USB peripherals, and in doing so remounts the disk, which then when it goes back to sleep is incorrectly ejected.
There seems to be a roughly 2 minutes cycling of power of the ports when it sleeps. Powers all down in about 30 seconds, all lights out, screens go dark. Then maybe 30 seconds later the ports power back up, the drive lights (and other USB devices) power back up, maybe for 30 seconds before then powering back down. The screens do remain dark throughout this per Sleep. All this happens while under Sleep, and carries on cycling ports power this way, mounting and ejecting drives incorrectly each time as it goes….. This doesn’t seem right? It never happened under Mavericks. Have I got a Yosemite bug or a hardware issue cropped up by chance when I powered down my computer over Christmas and then installed Yosemite as a clean install?
The Thunderbolt Lacie RAID is NOT being incorrectly unmounted. That's fine.
The two 1TB WD drives in a Hornettek Serial ATA USB 3 connected enclosure are being incorrectly unmounted during sleep as detailed above.
Both these external drives are directly plugged to the MacPro.

Whew, I thought I was the only one with this problem. I'm also getting the "double-click" sounds when trying to wake the machine up from the dead zone (after going to sleep- either on its own or after attempting to awaken it a few minutes after manually putting it to sleep).
I've had my computer serviced by a Mac-authorized repair center three times for this issue. The first visit resulted in an operating system upgrade to Leopard, which seem to fix the issue for a few days. When it reappeared, the second visit resulted in a logic board switch- the technician actually kept it there because the problem reoccurred after testing the new board. He then found a broken wire in the power supply and replaced that. On the third visit, they actually had to send it in to the Apple engineering department- who replaced the video card with an updated version of the same.
This is driving me insane- the repair center knows their stuff (I'm in IT, myself so I know they're not incompetent)... they've exhausted nearly every possible solution- replaced every component, different OS, etc... the apple engineers couldn't even fix it. I dread going to the Apple Store because I know the people at the Genius Bar are way less knowledgable than the guys I go to... but since I'm still under AppleCare, I may be able to get a machine swap if they can't fix the problem in a few weeks.

Mac Pro makes clicking sounds during startup

Recently my Mac Pro began making clicking sounds during startup or upon waking from sleep mode. Usually there are six clicks lasting a total of about 3 seconds, and then the clicking stops. After that everything seems normal.
Since my computer didn't used to make these clicks, I suspect something could go very wrong in the near future. I don't know if these clicks are coming from the hard drive, the fan or, perhaps, relays.
Can anyone help?

I moved both my hard drives to different slots
Do the drives themselves have relays in them or are there relays associated with each slot?
Hi, sorry for delay, an all nighter to re-assemble my case.
Interesting, just moving drives made a difference.
Possibly the jarring required to get them out & back in altered internal interference.
Or the drives connection made better contact. Tough call there.
The drives arms inside swing back & forth at blurring speed across the drive platter to read it.
Not sure how old the drives are, but like mine, they are about 3-4 years old, and I have a theory when they get to 5 years old, like me, I now start clicking going up stairs.
* The hardware test that's part of your OS install disc should report if it sees an issue with the drive.
It's also highly recommended to use http://www.alsoft.com/diskwarrior/index.html
By chance do you monitor the temps inside?
There are a few temp programs that will show components and their temp & rpm of fans.
I like http://www.macupdate.com/info.php/id/23049/smcfancontrol
This will let you bump up the fan speeds to where it made a huge difference when set at 1100 rpm.
At that speed, you just start to notice the fans, but it dropped my internal temps by 30 degrees. I had 174 degrees prior, which is not the best thing with large ram filled slots.
For reference, my temps now with smc', the hottest memory stays about 134 vs 174, and exhaust steady at 93, with ambient showing 82. I can live with that.
I occasionally run custom floor fan to move the air out of the room.
Ceiling fan is also on.
Back to drives"
You can also leave the case door off while running him.
The temps briefly add about 10 degrees max while I tested this.
Sit close while you have it on to pin point the clicks, but I still think it's the drive.
At first sign of clicking, rest hand at under side of drive to verify.
Drive 1 will not have that access.
Relays in theory do click, but in computers, they are micro small, I doubt one could hear them.
Were any changes made recently to park the drives?
This is usually not recommended.
I may have forgot something to add, but you have enough for the moment.
Good Luck, and if the inside needs it, use bright flash light to inspect closely and blow out
any excess dust.
The optical drive bay slides out easy, as do the RAM sleds.
Inspect power supply fan, and others for excess dust.
I just lay the case on it's side, and ribbon cable allows it to set the optical bay sled on the edge of case.
All connecting cables are removed from the outside of case prior.
Doubled up bed sheet works well on the floor, desk, table and protects from scratches.
I have airtank set at 30 psi from airbrush compressor to remove excess, and detailed with Q-tips dipped in alcohol. Including video card fan. Last nights mission.
Later.

Early 2008 Mac Pro frequently shut downs during start up, Help!

Hello all,
My early 2008 Mac Pro has gradually started having the following problems:
It will often shut down when it goes to sleep.
It has shut down randomly a few times.
And just today it shut down about 5-10 seconds after being turned on. It took about 6 tries before I could get it to turn on.
I have tried all of theusual software remedies (disk utility, different startup drives, resetting the SMC, PRAM, etc.)
I have run apple hardware test on loop for several hours with no errors appearing...
The computer also often loads up to a circle with with a slash through the middle sign, though I am not sure if this is related (it started happening when it switched my system over to a SSD).
I am wondering if this is simply a slowly sying PSU and if replacing it might help? If there any way of monitoring this perhaps? I somehow thought that if it was the PSU then it would simply die completely rather than fade like this...
Any ideas much appreciated!

There are multiple threads and reports of issues with Icy Dock - there is one on Amazon that lines up properly.
The drive sled length of 2009-2012 Mac Pro are longer. Maybe OWC needs to be clearer.
You'e right half-way and maybe some corrupt plist or interferring process you have, or even another hardware item or cable - external - even printer drivers or something that refuses or does not like sleep. Controller card?
All around I'd have to vote for Samsung 830 model. Then Intel 520. Crucial is out with x4 now (Or is it "V"?)
SSD firmware continues to be trouble. Even May-June the SandForce firmware had major issue and reason to hold off any using theirs. Reason to see if yours needed to be updated. Someone last week with m4 found they had old firmware and needed to update it.

My mac pro won't print pdf files

2. Go to the “File” menu and select “Get Info.” You also have the option of pressing the “Control” key on the keyboard while clicking on the file and selecting “Get Info” from the contextual menu.
3. Adjust the “Open with” menu to “Preview.” Press “Change All” to set all PDFs to open with Preview.
Thanks to everyone who tried to help me!

The tricky part is to define what is a disturbance
First do once a correlation to find and correct a shift in the signal
Look at the (absolute or squared) difference of both signals and define a threswhold and use the threshold detector vi
from the point location(s) calculate the time and log it.
And have a look at the waveform monitoring vis....

My Mac Pro "mid2010" locks the screen/ screen blacks out every some seconds.

This started last week with the installation of Mavericks. What can I do? Settings in Screensaver etc. are "normal", i.e. I did not change anything. The screen goes black totally randomly every 5 to 10 seconds. I usually have "require password to unlock screen". So it asks me to enter the password every time. That means it locks the screen ? I unchecked this option to be able to at least get some work done. I can wake the machine up by hitting any keys. There are several people working on this machine. Some of us use the Remote Desktop (RD) environment "vnc://..." but stopped using it, to make sure the problem is not related to the use of RD. The problem is still there. Does anyone have an idea. I cannot find any useful hints on this, nor was I able to find a similar problem.

How to make your own bootable OS X 10.9 Mavericks USB install drive
Apple has changed things in 10.9, but making a recovery drive is still possible.
by Andrew Cunningham - Oct 23 2013, 8:19am CDT
OS X Flickr user Prime Number
When Apple released OS X 10.7 two years ago, it stopped selling operating system DVDs in its stores, stopped shipping recovery disks with new Macs, and switched to downloadable installers for OS X upgrades.
These download-only installers have actually worked pretty well—I’ve never had an issue downloading the software from the Mac App Store or restoring a Mac using the Internet Recovery feature when something went south.
That said, it’s still nice to have an install disk handy for those cases when you don’t have a connection, when your connection is slow, or when you just have a whole bunch of Macs and don’t want to have to download the installer on each and every one of them.
The good news is, as with Lion and Mountain Lion, it’s possible to create a local USB installer for Mavericks. The bad news is that it wasn’t as simple as it was before—Apple has changed the way the installer works, and making an install disk manually is more difficult than it used to be. Before we get started, here’s what you’ll need:
An 8GB or larger USB flash drive, or an 8GB or larger partition on some other kind of external drive
The OS X 10.9 Mavericks installer from the Mac App Store in your Applications folder. The installer will delete itself when you install the operating system, but it can be re-downloaded if necessary.
The latest beta of the Lion Diskmaker app, available here (as of this writing, version 3 beta 3 is the most recent). This app is free to download, but the creator accepts donations if you want to support his efforts.
An administrator account on the Mac you're using to create the disk.
The easy way
Enlarge / Lion Diskmaker remains the easiest, most user-friendly way to get this done.
Andrew Cunningham
Once you've obtained all of the necessary materials, unzip the Lion Diskmaker app and run it. The app can currently make installers for OS X 10.7, 10.8, and 10.9, but we're only interested in Mavericks today.
Lion Diskmaker has actually been around since the days of OS X 10.7 (which explains the name), but it's more important now because Apple has made alterations to the installer that prevent the old Disk Utility method from working.
It's still possible to create a disk manually using a Terminal command (which we'll go into momentarily), but Lion Diskmaker presents an easy GUI-based way to do it that is less intimidating to most people.
One note of caution: Lion Diskmaker no longer supports creating OS X install DVDs. This isn't going to be a problem for any Mac that can actually install Mavericks, but if you'd rather use a disc than a USB drive you're apparently out of luck.
Anyway, select OS X 10.9 in Lion Diskmaker and the app should automatically find the copy you've downloaded to your Applications folder, but clicking "Use another copy" will let you browse the drive if you happen to have moved it.
It will then ask you where you want to copy the files—click "An 8GB USB thumb drive" if you have a single drive to use, or "Another kind of disk" to use a partition on a larger drive or some other kind of external drive.
Choose your disk (or partition) from the list that appears, verify that you'd like to have the disk (or partition) erased, and then wait for the files to copy over. The process is outlined in screenshots below.
The only-slightly-less-easy way
If you don't want to use Lion Diskmaker for some reason, poster tywebb13 on the MacRumors forums has your hookup. Assuming that you have the OS X Mavericks installer in your Applications folder and you have a Mac OS X Extended (Journaled)-formatted volume named "Untitled" mounted on the system, you can create a Mavericks install drive by typing the following command into the Terminal.
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
The command will erase the disk and copy the install files over. Give it some time, and your volume will soon be loaded up with not just the OS X installer, but also an external recovery partition that may come in handy if your hard drive dies and you're away from an Internet connection.
Whichever method you use, you should be able to boot from your new USB drive either by changing the default Startup Disk in System Preferences or by holding down the Option key at boot and selecting the drive. Once booted, you'll be able to install or upgrade Mavericks as you normally would.

ITunes locks PC during large downloads

This started happening about a month ago and there have been no major changes to my system (I've had this system for over a year).
PC running Windows Home 7 Premium 64 bit with SP1 and all available Microsoft updates installed. iTunes is version 10.6.1
The sytem locks during downloads - usually they need to be large such a video podcasts and now a movie. Downloads start and proceed at high speed to a point and then progress on the download stops and the indication of remaining time starts to go up. For example, I was trying to download a 383MB video podcast and it flew along up to 62.1MB and showed 2 minutes remaining to complete in the status. Then it went to 3, 4, etc. After 2 minutes elapsed time, it was 7 minutes and after 20 minutes it was 2 hours. However, the indication of estimated completion time is the only thing on the system that is active. The clock in the system tray stops almost immediately after the download progress stops nothing else is accessible - even Ctrl Alt Del and Ctrl Shift Esc do nothing, The only thing I can do is physically power off and them it takes over 20 minutes to get back into iTunes as I have a large library (over 24000 songs and about 30 movies).
This has happen consistently in several locations with high-speed internet and I've tried turning off wifi and going hard wire. Yesterday, I got a movie and the download to Flixster went fine and the iTunes download locked up. I have removed and reinstalled iTunes and deleted the content in the download directory. Also have unsubscribed and resubscribed to podcasts. Ideas on next steps would be appreciated.

Additional info - after 6 iterations of donwload/lock/reboot, I did successfully get the movie I bought (2.25GB of content) and it does play.
