USB connection suddenly extremely slow

As I ususally have manny film, series on my external hard drive connected to my Airport Extreeme, I suddenly got a big supprise when the speed suddenly got extremely slow. Not possible to use it for anything. The internet connection is however perfect.
As it has allways functioned perfectly for me I don´t know what to do. It was about that time I uppdated the Java pack resently submitted by Apple. But I can´t see why this should have aything to do with this.
Has anyone had any simmilar problems, and what is the remedy. I am all blank....

Keep in mind that the very first device you connect will determine the default speed for the entire USB bus. So, if you boot up the MBP, log in, and plug in a USB2 device, then the bus will never operate faster than USB2. You would then need to reboot the computer, and first connect the USB3 device to ensure the bus steps up to USB3 speeds for USB3 devices.
Also, make sure you are using a USB3 compatible cable with any USB3 devices to get max. transfer speeds.

Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

My iMac with Comcast is suddenly extremely slow

Suddenly my imac with comcast internet with apple airport is extremly slow.
This sort of came out of the blue.
I have called Comcast and they said everything on their end seems to check out fine.
Going a bit nuts here. Any ideas as to why this is happening?
Anything I should test?

ITunes connection is extremely slow

For the past five days my connection to iTunes has been painfully slow. This slowness applies to everything from updating podcasts to simply accessing the iTunes store. This seems to be unrelated to my internet connection as I haven't noticed any slowing in anything else I have done. All download rates, etc... are normal outside of iTunes. Has anyone else experienced this and what can be done to fix it?

I have the same problem, have been having it since the March 28. Sometimes iTunes won't even connect, tells me 'the connection has been reset'. But when it does connect, it is extremely slow, sometimes the pictures don't load. Searching stalls and I have to hit the stop button then hit enter to start the search again to get results. Let's not even get into previewing tracks. And as for downloading purchased songs, one night I purchased three albums, I went to bed at midnight at 6 the next morning, it was just starting on the first track of the third albums. Each of these albums total run time was less than an hour. Outside of iTunes my connection is just as zippy as it once was, I dunno why this is happening all of a sudden.
So far my solution has been to avoid the store. Because everything I have tried has been of no help to me whatsoever.
I share your pain though.

Sudden EXTREME slowness, crashing

I was using my Macbook Pro today for just regular stuff, playing some music, when suddenly it slowed down to a really ridiculous speed. I double-clicked on a song in iTunes, it went to the pinwheel and took 15 seconds before the song played. I figured I would restart, so I did and now the computer is literally slower than I could have imagined.
At first reboot it sat at the Apple logo loading screen for a long time, to the point where I turned it off and let it sit for a moment, then turned it back on. For the next five or so off / on cycles it displayed a blank light-blue screen and nothing else, not responding to any kind of input. Holding down the button to get to the boot menu to choose between Windows and Mac didn't work.
Finally I left it for quite a long time and it managed to boot up to the login screen after about 30 minutes of loading. I managed to type in my password (which took awhile, it went to pinwheel for about 10 seconds before recognizing keyboard inputs). Another 10 - 15 minutes before it displayed the desktop and dock, then another 5 minutes before it displayed the top menu.
It continued to run extremely slow, and over the course of the next hour I managed to open up Disk Utility and Activity Monitor. Activity Monitor shows random tasks as "Not Responding", as does Force Quit. Different tasks at different times show up red, including SystemUI, iTunes, and Disk Utility itself.
I attempted to verify the disk, it worked for a moment, displayed a few errors and then stopped with the message "Underlying task failed", or something to that effect. I tried to Verify Disk permissions and it threw a long list back at me before freezing. Over the next 20 minutes I managed to force quit Disk Utility, and now my computer is apparently entirely frozen.
The Windows drive also didn't appear on the desktop, and under Disk Utility my windows partition showed up greyed out and d03 or something like that.
I'm going to try to restart with the install disk and run Disk Repair off of it and see if it will work, but I was hoping someone out there had an idea of what's gone wrong with my MBP before I just wipe the whole thing clean and start over...if I can.
It's a Macbook Pro, one of the first-iteration Macbook Pros that came out a few years ago.
Thanks a bunch.

Thanks for the quick reply. I tried restarting with the install disk, but it failed to repair with the same error. I'm going to have to send it in now anyway because the install disk is now stuck in there. Hopefully (with my luck) it won't spontaneously explode before I can get it to an Apple Store to have them send it back, I guess.
Thanks.

Adobe premiere cs6 suddenly EXTREMELY slow and CPU intensive

Hi everyone,
I'm editing candon 5d mk III footage (h.264 files) on my late 2011 MacBook pro. Here are the specs..
240 gig SanDisk SSD harddrive (190 gigs free)
500 Gig (250 gigs free)
8 gigs ram
2.4 ghz i5 processor
Intel HD graphics 3000 graphics card
I'm a wedding videographer and I am currently closing my last edits of the season. I have edited 20+ 45 minute videos on Adobe Premiere CS6 and have had absolutely no issues at all. I enjoy working on premiere so much that I've been trying to get my videographer friends to give a shot and simplify their workflows.
Upon starting my second to last edit (same process as the other 18 videos I've done this season, organizing the footage within it's respective folder, loading it into premiere with the couples' choice in music and opening 4-5 new sequences based on the events of the day) I noticed that I was having a lot of trouble importing folders into my media bin. I had to import all of the footage unorganized because loading the folders "Preperation, Ceremony, Photos, Reception" with the footage within them would cause premiere to freeze and become unrepsonsive. So, finding no solution I added all the footage in no particular fashion. Just one large unorganized group. Then, while organizing the files into bins, I noticed even the smallest move would take several minutes to complete. Because I was working directly off of my hard drive I figured these kinds of delays would eventually catch up to me, so I moved all of my files to my HDD and decided to work on them there. The project itself continued to be extremely slow and started crashing regularly (especially when applying audio effects). After a few hours, I stopped being able to play 1080p video at all. It would jam and stutter so often it become unuseable. 720p video was the next to go along with my ability to render anything in less than 30 minutes - 1 hour. At last attempt to use premiere I was getting an "Unable to compile movie - Unknown Error" message when trying to render alpha channel things (lower third titles and things of the nature), my ability to change the resolution of the playback had disappeared (Going from full, 1/2 and 1/4 did nothing, it just remained at full quality) and finally doing anything in premiere caused it to use 300% of my CPU (based off of my Activity Monitors metering).
Does anybody have any clue as to what could be happening to my machine/program? I have a yearly subscription to adobe's creative cloud service if that helps. Oh and I've tried moving my media cache's from my HDD to my SDD with little or no results. Don't know if that helps.
Thank you to anyone who helps in advance. What I believe to be clean installs aren't doing anything so I'm hoping somebody can give me a hand.

Sounds to me like specific media is dragging the Mac to a halt. (300%, really Apple? Isn't that like saying that my car can go up to 90mph, but last night I drove it at 300% speed, 270mph)
Some things to trouble shoot:
Do you have any assets in the project that are loaded directly from strange devices, like a SD card or CD audio? Any dynamic link media that may be problematic?
Is there anything that makes this footage different than footage from successful projects?
Can you work successfully with an old project?
Can you successfully start a new project using different or less media?
Is the 500 GB drive internal or external?
One time I was sent out at from work to troubleshoot a system that would freeze up like yours. The guy was an idiot and rude client that demanded that someone from our facility help him fix his own project. He said that he had been troubleshooting for a day, and then had convinced his organization's IT guy that he needed a way over spec new pc to run Premiere.
His system was fine. Within 3 minutes of checking media in his project, I saw that top track of the problem sequence had a video clip that was set to a speed of .01%, and he had the clip stretched for 24hours in the sequence. His project was supposed to be a 2 minute PSA. All his issues went away after removing the idiotic Day Long slow motion clip. He complained to my boss because I had laughed at him.
I relate that story to illustrate that it could be a weird thing with you media or fx, just as well as a hardware or software issue.
Good Luck

USB connectivity suddenly partly gone

For the last two days, for no apparent reason, I've lost USB connectivity to my digital camera, printer and USB memory stick. The keyboard and mouse are fine thankfully, so I can still work.
I'm a pretty seasoned Mac compaigner so I've checked all the usual stuff.
(1) Yes, all the missing peripherals show up under the System Profiler, so the USB ports aren't blown.
(2) This is on a G5 and the front USB port won't show the USB stick, nor will EITHER rear USB port allow the powered hub to run the printer. The same hub has a Bluetooth dongle in it which still does work.
(3) Switching the keyboard and mouse around to the other rear USB port takes the problem with it: That is, the keyboard and mouse work in the port that was not working with the powered hub and the powered hub won't work in the port in which the keyboard and mouse just worked,
(4) I've completely removed the powered hub and stuck the printer directly into the (now available) port on the back and the printer still won't work.
I don't know what else to do. There's no consistency here. Both rear USB ports work in certain circumstances.
Thanks.

Computer suddenly extremely slow. Now grey screen.

Macbook Pro, OS X 10.6.8, purchased late 2009
Almost overnight, the computer became extremely slow when running apps. I tried multiple solutions -- verifying, repairing, etc. Yet as of now, its refusing to boot. Is there a way of restoring the system through time machine on an external HD on Mountain Lion? Does anyone strongly suspect (as I do) that this is the last gasp for the hard drive and a new one is in order? Or is the situation perhaps even more critical given the age of the machine?

It booted just now after many attempts, but is still extremely slow and unresponsive.
Once again, please: any help with the matter would be immensely appreciated. Would putting in a new hard drive solve the issue? I read somewhere that moving your computer when it's running can cause the drive to get corrupted. And in fact, that is more-or-less when my problems began.
Or should i try restoring the computer first through the OS X DVD?

USB Disk access "Extremely" Slow

I am unable to use my network disk essentially because the disk access write/read times are SO SLOW...I am better off running backups by connecting my disk directly to the compter. Does anyone else have this problem?
It took 5 Minutes to read my Music directory; connected directly via the same cable it takes seconds.
What gives?
Any help would be appreciated.

move a couple fils totaling 2 gigs over ETHERNET!
If I transfer the same files over the same network
between 2 computers the speed is much much faster.
Is this normal or some nasty firmware bug. It almost
feels like the AE is using USB 1.0 for some reason.
You guys are funny. How about checking out the specs of USB 2.0 and 802.11g/n?
Go here:
http://en.wikipedia.org/wiki/802.11g#802.11g
and here:
http://en.wikipedia.org/wiki/USB_2.0
Firewire vs. USB tests are here:
http://www.g4tv.com/techtvvault/features/39129/USB20_Versus_FireWirepg3.html
802.11g:
Release Date Op. Frequency Data Rate (Typ) Data Rate (Max) Range (Indoor)
June 2003 2.4 GHz 19 Mbit/s 54 Mbit/s ~35 meters
802.11n:
Release Date Op. Frequency Data Rate (Typ) Data Rate (Max) Range (Indoor)
Mid 2008 5 GHz and/or 2.4 GHz 74 Mbit/s 248 Mbit/s (2 stream) ~70 meters
Bottom line: 802.11n typical is 74Mbps, 802.11g typical is 19Mbps. USB 2.0 typical is 50Mbps.
On the average, you should expect your speed to drop by over 50% when connecting the USB drive to AESB using an 802.11g device. If your device is 802.11n, then you should have pretty much similar performance.
Now, if you increase the distance from your base station, or you put walls in between, the performance of 802.11g will go down "dramatically", all the way to 2-3Mbps, easy. Not so for 802.11n, which behaves much better at longer distances.

MBP suddenly extremely slow, checks return fine - anything else?

Hi there,
The issue: MBP had been working fine but all of a sudden it is frustratingly slow to the point it is near unusable. This literally happened overnight - it was fine, then I woke up to use the laptop and these issues occured. 95% of requests (clicking on something) are followed by a few sections of nothing, then the spinning pinwheel for anywhere from 5-30 seconds, this also happens when scrolling or opening web pages or writing things in word or on the web. I have just timed my boot up at 3.23mins and I have nothing that opens on boot up.
Spec: I am using an MBP mid 2012 model, 2.5Ghz Intel Core i5 processor, 4GB 1600MHz DDR3 memory running OS X Lion 10.7.5. The 500GB hard drive has 323.13GB free space and 2.69GB free memory.
So far: I have removed any external additions, unplugged anything that was plugged in, disabled my firewall and turned off WI-FI - this didn't help. I have checked the CPU usage and the computer is having issues even when running at 95% idle. I just did the AHT which reported no issues and checked the HD in disk utility - it gave me both the brand, model, size of the HD which as far as I know means theres no hard drive issue (correct me if I am wrong). I also just finished backing up all my files on time machine which took about 2 days.
I know there have been similar threads which is where I got most of my troubleshooting noted above from. I am aware that it would also seem logical to take the laptop to get checked out at the apple store, however I am an international student at college in quite a remote area - the nearest apple store is at least 90 minutes away and I am unable to drive cars in the US. We do have a computer store on campus who have technicians however they charge regardless of if they can help - I am wondering if there is anything else I can do myself to fix the issues, or at least determine what might be causing them, before taking the laptop in to be seen as a last resort.
Any help at all would be greatly appreicated.
Thanks.
P.s, apologies for the length of this, I have tried to be as in-depth as possible to avoid any time wasted asking simple questions etc.

If you don't already have a current backup, back up all data before doing anything else. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem. The backup is necessary on general principle, not because of anything suggested in this comment. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
Below are instructions to run a UNIX shell script, a type of program. It does nothing but produce human-readable data about the state of your computer. However, you need to be cautious about running any program at the behest of a stranger on a public message board. If you question the safety of the procedure suggested here — which you should — search this site for other discussions in which it’s been followed without any report of ill effects. If you can't satisfy yourself that these instructions are safe, don't follow them.
Here's a summary of what you need to do: Copy a line of text from this web page into the window of another application. Wait about a minute. Then paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only run the test in safe mode, proceed anyway.
If you have more than one user, and the affected user is not an administrator, then please run the script twice: once while logged in as the affected user, and once as an administrator. The results may be different. The administrator is the user that is created automatically on a new computer when you start it for the first time. If you can't log in as an administrator, just run the script as the affected user. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the script will run anyway, but it will produce less information. In most cases, the difference is not important, so don't worry about it.
The script may take up to a few minutes to run, depending on how many files you have and the speed of the computer. Wait for the line "[Process completed]" to appear in the Terminal window.
You can then quit Terminal. The output of the script will have been copied to the Clipboard automatically. All you have to do is paste into a reply to this message by pressing command-V again. If any personal information, such as your name or email address, appears in the output, anonymize it before posting. Usually that won't be necessary. Please don't copy anything from the Terminal window.
When you post the output, you might see in your browser the message, "You have included content in your post that is not permitted." That's because the forum software falsely identifies something in the post as a violation of the terms of use. If that happens, please post the output on Pastebin, then post a link here to the page you created.

Suddenly extremely slow Time Machine backups on Time Capsule

My Time Machine backups on Time Capsule have been pretty good in the last few months. In the last week or so I am seeing painfully slow backups. It's not the preparing or the finishing phase, it's the backup itself. Data transfer for other apps is fine. The backup transfers about 50 Kb per second. In more than 3 hours it backed up about 600 Mb. Here's what I get from the Console:

Any clue? What happened? (I did an Airport-related upgrade recently)
My set up is a Time Capsule and an Airport Extreme.

Well, this link has a video describing a downgrade:
http://www.mefeedia.com/entry/airport-extreme-and-time-capsule-firmware-downgrad ing/11537477/
It has been mentioned in apple discussions here as well, but with no other information than that it has helped some people.

Internet suddenly extremely slow on windows 7 partition.

Hello all,
Here is my situation: I am connected to the internet via ethernet, Im on a current generation iMac, and Im running windows 7 through bootcamp. About an hour ago, I logged in on my windows partition to find that my internet connection was running unnaturally slow. I tested its speed via an online speed test to find that my ping was an unexpected 479ms, where as, when I tested it on my mac partition, it was a mere 25m. The most peculiar thing about this issue is that im earlier this today (two hours earlier) my connection was perfectly fine.
The other piece of information I have is that on my windows partition, my connection will spontaniously die about 10-30 minutes after launch very freuquently. To restore my connection, about 70% of the time I can simply unplug and replug in the ethernet cable, but if that doesnt work, I have to pull a full restart. I've only noticed this on my windows partition, though I generally game on windows also, so its possible its just my cable, and I dont notice it while on my mac partition.
Thanks for your time.
-Will

UPDATE: I just checked and my connection speed has been miraculously restored to a ping of 30ms. Though if anyone has any ideas as to why this is happening, Id like to hear them in case this happens again.

Suddenly extremely slow

Hi all.
Suddenly my Mac become very slow. Please help, Its been playing up for a while since I install adobe and then updates came through. I tried some free virus scan (one downloaded from apple store) but it is even worse then ever. I cannot even back anything up. some things i can't open and it would take hours.
its Macbook Pro. OX 10.7.5. Lion. bought it August 2011.

Your problem is excessive swapping of data between physical memory and virtual memory. You're not out of storage space.
That can happen for two reasons:
You have a long-running process with a memory leak (i.e., a bug), or
You don't have enough memory installed for your usage pattern.
Tracking down a memory leak can be difficult, and it may come down to a process of elimination. In Activity Monitor, select All Processes from the menu in the toolbar, if not already selected. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more memory over time without ever releasing it.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details:
Memory Usage Performance Guidelines: About the Virtual Memory System

Safari on my new iMac 27" running 10.6.3 suddenly EXTREMELY slow.

Hi is anyone having a similar problem, suddenly my Safari browser has completely ground to a half. I tried installing Chrome on my Mac to see if it is a Safari problem and Chrome is just as slow.
I am running a Windows 7 and a Linux machine on my home network as well and they run perfectly via the same Wireless router and ISP.

Hi and Welcome to Apple Discussions...
Several things to try...
One, login to another user account, launch Safari. If it lags there then it's a system wide issue, not just isolated to your Home Folder.
Next, from the Safari Menu Bar click Safari/Reset. Select the top 7 buttons, click Reset. Relaunch Safari. See if that speeds things up.
If that doesn't make a difference, go here for trouble shooting 3rd party plugins or input managers which might be causing the problem. Safari: Add-ons may cause Safari to unexpectedly quit or have performance issues
If the issue it's third party plugins, go to the Safari Menu Bar, click Safari/Preferences. Make note of all the preferences under each tab. Quit Safari. Now go to ~/Library/Preferences and move this file com.apple.safari.plist to the Desktop.
Relaunch Safari and see if that makes a difference. If not, move the .plist file back to the Preferences folder. If Safari functions as it should, move that .plist file to the Trash.
If you have anti-virus software installed (for Mac), that could be a factor.
If you didn't repair disk permissions after the update, do that as soon as you can.
Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and restart your Mac.
