Extremely Slow Startup/ Difficulties with Freezing

My Mac worked fine one day. I literally used it for one hour and shut it off, and it acted perfectly normal. Nothing was out of place or acting strangely. I waited a few hours and brought it to another house and tried to start it up. It froze on the apple/gray screen and went nowhere. On top of that, if it fell asleep, it would shut itself off. Eventually and currently, I can get it to start up, but it usually will take between ten and fifteen minutes to get to the log in screen and just as long to get to my desktop after that. It also does not go to shut down anymore if it goes to sleep.... usually.
From there, I usually pull up iTunes. Everything will work smoothly, until I try to change multiple items or import a CD, during which, iTunes will freeze up. It's especially horrific when I have another song playing. Sometimes the music will keep playing, and the timer will freeze, but eventually the music will stop until my computer can catch its technological breath. This freezing also will spread to the whole computer; granted it only lasts for a few seconds at the least and five minutes at the most.
Microsoft Word 2008 also give me this problem. It seems that whenever it saves, it likes to give me the same problems that iTunes does. No other programs that I've noticed have had this problem, however, these two programs are the ones i use the absolute most.
It's almost like it's just too much for my computer to handle. My computer is only a year and three months old (Or is that too old?). I've deleted many useless files and programs, as that's as far as my computer knowledge will let me think of to do. I've been told to try and boost/ restart the "PRAM" and have seen that do absolutely no good. I'm at a loss.
I tried to update my safari for the new iTunes (I'm currently on firefox) and it involved a restart in order to update. It failed epically because the start up took too long, and it stayed on one screen forever, not even the updating screen. I have to find a way to fix it, whether that be something I'm able to do myself or sending it to someone when and if I have the money.
I need help and any suggestions will be welcomed warmly, before I feel like I must send it in and pay money.
Thank you.
Caitlin

Welcome to Apple Discussions!
How full is your hard drive? You should have 15-20% free. If your drive is too full, it could cause sluggish behavior.
Is the S.M.A.R.T status of your hard drive verified? If it is not, then your drive is failing, which can also cause freezing. If this is the case, the hard drive will have to be replaced.
Is all your RAM recognized? If not, try reseating it. Your Mac will be very slow if some of your RAM is not being recognized.
Do you have a lot of LogIn items? Check these under "Accounts" and eliminate all that you don't really need. Often when you download software, it will install itself as a log in item, which means it opens when you start up your computer. If there are a lot of these, start up will take a long time because they all have to open.
Have you tried reinstalling the OS with an Archive and Install? Some freezing can be software related.
Your computer is not too old--many of us have even older ones which are working without issue. You just have some issue which is keeping your Mac from working properly.
Do you have a good backup? If not, you should place a high priority on making one. One possibility for the freezing is that your hard drive is going south, and if that is the case, you are at risk of losing everything. In any event, making a good backup is a good idea before getting involved in a lot of troubleshooting.
Are you under warranty? If so, any hardware problems would be fixed for free under warranty.
Maybe the first thing to try is to evaluate your hard drive. Check that you have adequate free space, and if not, freeing up more space will be the next step. If you're not sure what is taking up the space, there are some utilities which will help you to see what is:
http://www.derlien.com/
http://www.omnigroup.com/applications/omnidisksweeper/
http://www.id-design.com/software/whatsize/
Also check the S.M.A.R.T. status. If it says "Verified", try running this utility:
http://www.versiontracker.com/dyn/moreinfo/macosx/32454
You can download the demo and run it several times for free. It will give you a more comprehensive view of the physical health of your hard drive than Disk Utility will, and you may get an early warning of impending drive failure.
Try checking out the RAM and hard drive, and report back with how it goes. If it isn't clear to you how to proceed, or if you have any further questions, please post back.
Good luck!

Safari 3.1.1 Extremely slow startup times (Suddenly)

Hi I'm running a Macbook with a 2.4 GHz Processor, (Intel Core 2 Duo), 4 Gigs of ram and Mac OSX Leopard 10.5.3.
this mac is about 2 months old and suddenly am having extremely slow startup times with Safari. The rest of the computer is very fast, this problem is only with safari... It used to open with about 2 or 3 bounces on the dock... now suddenly its around 15-20 bounces before it opens. It bounces this many times, and then I receive the beach ball for a few seconds. I am assuming it is probably a build up of some files, or tasks it runs through to open... It is worst when you open it for the first time after powering on the mac, after you open it, and close it it opens up a bit faster.
I have tried the basics, i.e. resetting safari and things like that.
Most of the suggestions for deleting files out of the User>Library> are for older OS's and do not apply to Leopard...
Any suggestions?

Navigate to this location: Macintosh HD/Users/YOURUSERNAME/Library/Preferences and delete the following files:
com.apple.safari.plist
com.apple.safari.RSS.plist
Do this with Safari NOT running. See if that solves the problem.

Extremely slow wireless printing with HP Photosmart Premium C309g-m

I'm seeing extremely slow print speeds when printing wirelessly from a Mac or a Windows XP system to a new HP Photosmart Premium C309g-m printer. The printer begins printing immediately when I request a print, but it only prints one line. It will then take about 15 minutes to print the rest of the page, printing each line after a very long pause. Demo page printing doesn't exhibit this problem, only documents from programs like Word 2008, Safari and Firefox (tried firefox on PC and Mac) are affected.
If I connect to the printer through a USB connection it prints fine, so this problem appears to be with wireless printing only.
Printer: HP Photosmart Premium C309g-m
Computer: Mac mini (Late 2009 model) (also tried a Windows XP laptop as a comparison, using latest drivers from HP's website)
OS: Mac OS X 10.6.2 with all available updates installed
Computer connection method: Wired Ethernet connection to wireless router
Printer drivers: version 2.2.1 (Apple supplied, HP drivers never installed as system shipped with 10.6)
Wireless router: Apple TimeCapsule (Early 2009) 1TB, running in a/n and b/g modes on 2.4 and 5GHz. TimeCapsule is in bridging mode as the DSL modem handles DHCP service
Encryption: WPA2 Personal, no MAC filtering or hiding of the SSID.
IP addressing scheme: All addresses are handed out by DHCP server with no reservations of any kind
The TimeCapsule is sitting three inches from the printer and the printer indicates full signal. Connection of the printer to the wireless network and setup of the printer on the Mac went without a hitch. Only when printing a test document did we discover the problem. The wireless network is behaving as expected when accessing the Internet from both Mac and Windows devices (tested with a Dell laptop running XP and a MacBook running OS X 10.6.2), so I don't see any overall problems with the wireless network.
Attempted remedies:
1. Rebooting and powering off, waiting, powering on computer
2. Resetting the print subsystem, turning the printer off and on again and reinstalling the printer
3. Unplugging power from the printer and letting it sit for several minutes before trying to print wirelessly.
None of these worked.
This question was solved.
View Solution.

I don't think there is anything wrong with the DSL modem HW. There might be an issue with how print data is being routed though.
Please try the second experiment where you blank-out the default gateway and DNS entries from the printer's internal web configuration page. Open the printer's internal web page by browsing to its IP address. Select Networking and then Wireless (802.11). Under the IPv4 Configuration tab, select Manual IP:
For Manual IP Address, use the existing printer IP address.
For Manual Subnet Mask, use 255.255.255.0
For Manual Default Gateway, leave blank. This is important.
Select Manual DNS Server:
Leave both the Manual Preferred DNS Server and Manual Alternate DNS Server fields empty. This is important.
Press Apply.
Turn off the DSL modem, the printer and all computers connected to your network. Wait 60 seconds then turn on the DSL modem and then turn on the printer. Then turn on the computers. See if this corrects the printing speed.

Extremely slow startup/"Error loading kernel" when single user mode is run

My daughter's iMac has become very poorly responsive with a very slow startup time. It takes about 1 minute for the progress wheel to begin when I startup her machine. And then it takes another 2 1/2 to 3 minutes before the login screen appears. The computer runs very slowly with the spinning activity wheel occurring frequently. When I start it up in single user mode I get the following message on screen:
efiboot loaded from device: Acp:(PNP0A03,0)/PC: (1F12)/SATA(0,0)/HD(Part 2, Sig56BF F8F1-9ADB-4101-BD3C-BFBC38AEED26)

Could some one tell me what this means? And better still, what do I need to do to fix it?
Thanks.

I can't picture what is doing this other than something missing or muxed, but perhaps it's time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...

Extremely Slow Startup, Blue Screen, and Poor Performance

Hello,
A couple of weeks ago my MBP 15" (late 2009 model) started performing really poorly. The colour wheel would spin for about 2 minutes if a launched any applications and everything was really slow. It also took about 10 minutes on the grey apple screen to startup and then another 10 or so on the blue screen before slowly revealiing my desktop.
I took it into the genius bar and the said it might be a corrupt file on the HD. Backed up my HD, zeroed the drive and reinstalled OS. Still the same problems. Ran disk utility several times and got various errors pertaining to HD or RAM.
Took it back into the Genius bar and they ran a long diagnostic on it, came back to me and said it is deifinatly the RAM. I replaced the ram, (2x2GB ddr3-1066 sodimm) and cleared PRam. Still the same startup and performance issues.
Any ideas would be appreciated as this is stressing me out big time as I dont know what else it could be?

Hmm... before this I think I would have restarted the computer in Safe Boot mode which deletes the dynamic-loader shared cache.
Not sure if it is relevant at this point
Safe Boot
# it forces a directory check of the startup volume.
# It loads only required kernel extensions (some of the items in /System/Library/Extensions).
# In Mac OS X v10.3.9 or earlier, Safe Mode runs only Apple-installed startup items (such items may be installed either in /Library/StartupItems or in /System/Library/StartupItems; these are different than user-selected account login items).
# It disables all fonts other than those in /System/Library/Fonts (Mac OS X v10.4 or later).
# It moves to the Trash all font caches normally stored in /Library/Caches/com.apple.ATS/(uid)/ , where (uid) is a user ID number such as 501 (Mac OS X v10.4 or later).
# It disables all startup items and login items (Mac OS X v10.4 or later).
# Mac OS X v10.5.6 or later: A Safe Boot deletes the dynamic loader shared cache at (/var/db/dyld/). A cache with issues may cause a blue screen on startup, particularly after a Software Update. Restarting normally recreates this cache.

Did you run the Apple Hardware Test. What is the S.M.A.R.T. status, could be that HD is failing?

Java 1.5.0_05 extremely slow startup

Hi,
I'm a PHP, Pascal and was a VisualBasic programmer (until I stopped using Windows)...
So considering the fact that I have all the time in the world (still in highschool) I decided to try java, but there is a huge problem:
Every, and I mean every java application I start loads abnormally slow.
NetBeans won't load and what's even worse is that java freezes firefox when it tries to load a java applet.
Therefore I came to the conclusion that something must be wrong with my system.
So I fired up Azureus and made a -verbose pass to java and this is what I've found out:
Azureus stops for at lease 5 minutes between this:
[Loaded sun.reflect.GeneratedMethodAccessor1 from __JVM_DefineClass__]
and this:
[Loaded sun.nio.ch.OptionAdaptor from /opt/jre1.5.0_05/lib/rt.jar]
And the question is...
Does anybody know why java starts so slow?
Thanks,
papa Strumpf
P.S.:
My system is an Athlon XP 3200+ with 512 MB of RAM
I'm running a 2.6.13 kernel on Fedora Core 4

I have experienced the same error, and did some searching.
I've found this thread:
http://intellij.net/forums/thread.jsp?forum=22&thread=177641
Apparently, the timeout is due to the fact, that the program first tries to use ipv6 instead of ipv4. If your local ipv6 policy is set to block all ipv6 traffic, the java program waits, until the connection is timed out, and the program falls back to ipv4.
The solution is to allow local traffic on the ipv6 interfaces. I have tested this with Azureus and Maple 9. After the settings were changed, all programs have started up normal.

Extremely slow ipod syncing with Music located on a NAS

Hello,
I have been desperate to sync 3000+ MP3 songs located on my Synology ds412+ NAS Server to my ipod touch 5G (32GB) via itunes 11 and USB2.
I use a Sony Vaio laptop with windows 8 x64 and 8gb RAM.
First of all, it was very slow to add the songs folders into itunes's librairy. Itunes's media folder is in a mapped drive of the NAS.
Then prior to syncing, I went to the music tab and selected my own playlists. Itunes could not stop freezing, the blue wheel spinning and so on.
I had to wait several minutes for Itunes to get back to normal.
Finally, I managed to start the sync process. Songs are now beiing copied, but it only did 750 songs in 5 hours. Which means I would still need more than 10 hours to complete the process!
I hope some of you have experience in syncing music stored in a server.
Thanks for your input.
Regards,
Ambientic

I don't believe you can do that. The convert to 128 bit only converts the songs being written to the iPod. Every time you play a song it changes (the play count goes up) so iTunes is going to go try to find those and update them every time it syncs.
I am able to disconnect my external that holds my movies and the movies remain but those are not being converted. I think that is where the problem is.
Good luck!

Extremely slow PP Export with Dynamic Links

I have very slow exports from Premiere Pro that are entirely made with Dynamic Links to AE (green screen footage).
It's taking about 4+ hours to export a 12 minute video!
I'm on an iMac late 2012
3.2 GHz Intel Core i5
24 GB 1600 MHz DDR3
NVIDIA GeForce GTX 675MX 1024 MB
OS Yosemite
Footage is on an external HD
Project file is on main HD
Writing exported file to external HD
I've followed several troubleshooting tips including:
Uninstall and re-install CC 2014
Clean adobe media files
Check permissions on all folders
Switch Open CL to Software Only
Unchecked "Display out of sync indicators for unlinked clips"
Disabled "Show Duplicate Frame Markers"
Disabled "Show FX Badges"
I've also tried changing the location of where the final file is written to.
I've also tried this on my MBP with 2.3 GHz Intel Core i7, 8 GB RAM and AMD 6750M
Same results.
Any ideas? Am I missing something obvious here?
Thanks.

Extremely Slow Network Performance with 10.5.8

Let me start off by saying I don't use my mac mini much at all but when I do, the network is incredibly slow and unbearable. Half of the pages don't load, ipsw files for the iPhone take 20-30 minutes (with 15mbps interwebs)
My network setup:
1. Modem (provided by ISP)
2. 2 TB Time Capsule WPA2 security default settings.
3. Airport Connection
Now I would be for using 'openDNS' for a resolution but it didn't really improve the issue. Sure it sped up the internet on that machine, but I'm not willing to use a third party DNS when my MacbookPro connecting to the same exact network, doesn't experience this.
I have removed the hosts file for airport, remove the network connection, reset SMC, to no avail.
If anybody has any insight as to why my mac mini is the only device with poor performance, that would be greatly appreciated.

I shouldn't have to use another user.
Okay. It should also work with your current user but it's not.
For testing purposes and to narrow down the problem, try another user and see if it works.
If it works, it is something with the current user.
If it doesn't work, it is something with the system.

Mailbox moves extremely slow and stopping with StalledDueToCI status

I am migrating mailboxes from Exchange 2007 to Exchange 2013. I have an Exchange 2013 DAG. Previously I was running Exchange 2013 CU2 and had no issues with migrations, they were migrating fast and had no issues. After upgrading Exchange
2013 to SP1 I have had very slow migrations and they eventually halt with the StalledDueToCI status. I was originally doing batch migrations, I dropped it down to a single move request and even migrating a single mailbox from one database to another
on the same Exchange 2013 server and I still have the same issue. I've also tried moving a mailbox to a database that is not part of the DAG and I still have the same issue. I have the ContentSubmitters group so that's not the issue. Once
it stalls I have to restart the MRS and it kicks off again but then it stalls again with the same error. ALL of my databases have a "Healthy" status for the content index. Any help would be appreciated. Thanks.

These two are repeated:

Extremely slow PS3 downloads with E3000 wireless

As stated in the subject my PS3 downloads are horribly slow with my new E3000 (replacing a WRT54GS). PS3 does not show transfer rate but it is taking up to an hour for 50 MBs. I would generally expect to see 500 Kbps - 1 Mbps at a MINIMUM with my cable package so this is way outside the realm of acceptable transfer speeds...
I have seen this through several patches and DLC off of PS3 over multiple days. I have already decreased MTU from 1500 to 1365 to help with PS3/Netflix troubles based on other posts in this forum (that did seem to help).
As you can see I am not the only person seeing this problem with E3000 and PS3 - there is a common theme here:
http://boardsus.playstation.com/t5/PlayStation-Network/SLOW-DOWNLOAD-SPEED/td-p/45496873
I am not sure if there is some setting I can change to affect PS3/E3000 wireless transfer or if this is just a flat out bug that needs addressing by Cisco/Linksys?
Thanks for any thoughts you may have,
-Dan

Try this.
1) Application and gaming TAB, section QOS, enable Internet Access Priority, click down menu, select MAC Address. Enter PS3 for name, and enter your PS3 MAC address, which is found in your PS3 Network status listing. Save Settings.
2) Wireless TAB, under Basic Wireless settings, change your channel other than 11, 9, or default. I chose 6, but you can choose whatever, except 9, or 11. That is the most popular channel for 2.4ghz protocol. So everyone in your neighborhood who uses wireless connections would be using it. Default is 11, I believe, on all routers, big or small. Save Settings.
3) Under Advanced Wireless Setting, in the same Wireless Settings TAB, in the 2.4ghz section, change Beacon Interval to 75, DTIM to 3, Fragmentation Threshold 2304, and RTS Threshold 2304. Save settings.
4) Setup TAB, under Basic setup, change the MTU to 1365.Save Settings.
Now, on your PS3, you would need to let the PS3 Network settings to change, and then run the test. Got to Network Settings, Change Network Settings, choose Easy. You need your passphrase on this one.
I was going to return this router today, and buy a different one. I've tested the Internet Settings on the PS3, over and over, with consistent download/uploads. Hope this helps.

Extremely slow math execution with Solaris Studio 12.3 Fortran

I have a large Fortran program that I ran on a variety of problems. One case ran extremely slowly compared to all of the others (many hours versus a few minutes) and I managed to boil the problem down to the following program. For some reason, the line "y = (cos(x)**2+sin(x)**2)**1.5" takes several thousand times as long to execute when x is 1.278d-06 as when it is 1.279d-06.
program math_bug
call sub(1.279d-06)
call sub(1.278d-06)
contains
subroutine sub(x)
real(kind=8),intent(in)::x
integer     ::i
real(kind=8)::t(2)
real(kind=8)::y
call cpu_time(t(1))
do i=1,10000
    y = (cos(x)**2+sin(x)**2)**1.5
enddo
call cpu_time(t(2))
write(*,*) "Time: ",t(2)-t(1)
end subroutine sub
end program math_bug
Output:
Time: 3.1380653381347656E-3
Time: 13.27063798904419
I'm running Solaris Studio 12.3 on Red Hat Enterprise Linux Client release 5.11 (Tikanga) and compiled with no special flags -- simply f95 math_bug.f95 -o math_bug.
Can someone please look into this?
Thanks very much,
Mike

That's a bug in the 64-bit Linux libm library. The default compilation for Studio on Linux is -m64. With that default, you get:
ldd a.out | grep libm.so
        libm.so.6 => /lib64/libm.so.6 (0x0000003fd4600000)
a.out
Time:   1.8830299377441406E-3
Time:   12.055269956588745
However, if you compile with -m32 to create a 32-bit executable (and 32-bit libm), you get:
ldd a.out | grep libm.so
        libm.so.6 => /lib/libm.so.6 (0x008b6000)
[chvu@scapen-ssol5-0 misc]$ a.out
Time:   2.3509999737143516E-3
Time:   2.397000091150403E-3
Therefore, if your app does not require 64-bit address space then you might work around the problem with the -m32 option.
Since, the Linux libm is not produced and shipped by us, there's nothing that we can do about this. This has to be addressed by the Linux community. If this test it turned into a simple C program then I guess you can reproduce the problem with any C compilers. Fortran is high-level language so some Fortran vendors might choose to ship their own math supporting libraries with the compilers and that makes it harder to compare.

Extremely slow internet speed with GT60 ONC

Ever seen I connected to my college's wifi, my connection has been terrible (1.5mbps or less). At first I assumed it was the service here but people on the same floor as me are getting over 15mbps. My wifi at home was fine as of Wednesday but I haven't been there to try it since. Also, when I plug directly into the ethernet in my dorm, no icon appears saying that I am plugged in. Can anyone help me?

I do have the correct download but still getting the same error. I was getting better connection in my friend's dorm but not quite what I should and me being in their room seemed to slow their connections. Other people on my floor are having perfectly good connections. Also, when I plug in an ethernet cord, I get no icon or sign of the computer recognizing one has been put in. I think this may be related to something I uninstalled when I first got the computer. Chrome was crashing on start up until I uninstalled something that I believe had "Killer" in the name so I'm afraid it had something to do with the network card driver. I'm not sure if this is relevant but when I go to Device Manager, there is something called "ethernet controller" under "other devices" that has no driver installed. Any other suggestions, thanks for the help so far.

Extremely slow startup since updating to 10.7.2

each time I turn the Mac on, it first complete an installation bar, then asks for password (it never did before) and then it´s finally on (after 5 or 6 minutes). it´s now slower than my PC!!!! :-(
I have a Mac mini 2.4Ghz core Duo with 8GB ram. it can´t be this slow!
any suggestions?

Hello:
I don't know about the "slow," but try this for the mouse problem:
Trash a preference file (com.apple.bluetooth.plist) and restart.
Reset the PRAM and SMC
Make the mouse a favorite
