System wide lag

Hello guys, new member here.
I'd like you guys to help me out with something here.
I have a 13 inch, mid 2013 macbook pro with a 2.9 ghz i7, 8 gb RAM and a 750 gig HDD.
My problem is every now and then there is a system wide lag which freezes pretty much everything and audio playing from itunes also pauses during that time, it's quite frustrating as i've been searching for a fix since yesterday but havent found anything that can completely fix it. Usually there is only itunes, safari, mail and maybe one or two more things open at a time. I have checked my HDD for issues but there seem to be none. I suspect that this is related to the CPU since while I was using safari, a process called WindowServer would start using around 35% CPU, with nothing that intensive open on the browser
Note: This was ocurring much more frequently this morning but it has gotten a bit better now after I downloaded chrome and started using it instead of safari, I would, however, like to use safari instead.
Thanks in advance, I would be very thankful if someone could help me out with this, I have my exams coming up and I rely on my laptop for a lot of stuff.

I've got this problem on Macbook pro (mid 2010, 2,4ghz i5, 8gb ram, nvidia gt330m)
I don't think it ever happened before upgrading to mavericks. But now it's horrible!
It seems to only happen to me when I'm running unity3D, but does happen every minute or even more often. And the system freezes for anywhere between a second and 15 seconds...

Fresh install, random 100% drive usage and system wide lag.

Hi there, i just fresh installed Win 8.1 after having the issue of a svchost thrashing 100% disk access for minutes at a time and lagging whole system inc mouse pointer to the point that apps and games start to crash and the issue has not gone away.
I had also had the issue on old pc using different drives.
This is the 4th system where ive seen this behaviour in Win 8 since launch and was wondering if there is a fix yet? It happens on my 2 pc, my mothers laptop and a friends desktop, all with different hardware, 2 factory installs and 2x fresh installs
from untouched iso's.
It happens randomly when nothing is running on pc or sometimes when gaming or using apps and makes the desktop unresponsive for minutes at a time and sometimes crashes apps with it due to the system wide lag. Even ctrl alt deleting can take several
minutes for the menu to appear or even start Task Manager.
Ive managed to catch 1/2 the issue with procmon but due to taking so long for apps to launch while the lag happens i can only get the last 1/2 of the trace which shows a mix between a svchost, explorer.exe and wmiprvse.exe thrashing the system to a standstill
while accessing almost every file and reg key on the disk to over a million events recorded in procmon.
IS there a fix for this or a way to check the procmon trace to see exactly what service or task is causing the thrashing? I think whatever it is is buggy/broken, running at realtime and is blocking anything else from using the system until its done,
which lags the system.
Surely even an overloaded drive wouldnt cause other apps or the mouse to lag/hang so badly to the point of crashing and even Xp or Win 7 wouldnt lag/hang the desktop due to a busy drive.

In order to diagnose your problem you will need to download and install the below
Install the WPT (windows Performance Toolkit) http://social.technet.microsoft.com/wiki/contents/articles/4847.install-the-windows-performance-toolkit-wpt.aspx ,
When you have open an elevated command prompt and type the following
WPRUI.exe (which is the windows performance recorder) and check off the boxes for the following
First level triage, CPU usage, Disk IO. If you problem is not CPU or HD then check off the relevant box/s as well (for example networking or registry)
Let it run for 60 secs or more and save the file (it will show you where it is being saved and what the file is called
Zip the file and upload to us on Onedrive (or any file sharing service) and give us a link to it in your next post.

System-wide lag spikes. Possible reasons?

Hi!
I have been having issues with my iMac for quite some time now and i have never really succeeded to figure out what might be causing it. The profromance of my iMac on regular basis is outstanding as I would expect it to be. How ever, every once in a while i would get an system-wide "lag spike". Everything would frzee for a second or two and the rainbow loading circle pointer would appear. During that time i cannot do absolutely anything besides move the mouse pointer.
This issue, I believe, started to take place after i replaced my HDD with SSDs. I have two raided OCZ Aggility 3 drives. I use the iMacs old HDD as an external storage. The old HDD has been formatted. Also i would like to point out that according to some standard SDD benchmarks i am not getting the performance one would expect from them.
Else than that, my iMac is mid 2010 2,8 ghz i5, i have 12gigs for 1333 DDR3 and im currently running on Mavericks, but i did have this issue on the previous versions as well.
This is my first post ever so please go easy on me. If you feel i havent written or explained enough please do let me know and i will see it corrected.

Suggestion: airtunes should be a system-wide "sound out" option.

instead of limiting itunes to using the airtunes option. shouldn't it be made an option in the "sound out" control panel? that would make sense... it should be easy to do as well...
cheers,
pierre

Hi Pierre,
I believe the reason that its not a system wide option is that the sound is streamed to the Airtunes, and therefore there is a lag which would be problematic for watching movies, garageband or other apps which would require synching the sound to what you are doing or seeing on your computer.
I have heard a product called airfoil, but have no personal experience with using it.

Is there a system wide audio manager?

I'm trying to find a system wide audio manager for my MacBook Pro that won't cause voice lag or delays. Any suggestions?

they say :
To remove Audio Hijack Pro, simply place it in the Trash. If you've installed any of the extra components, you may wish to uninstall them first using the Install Extras menu item in the Audio Hijack Pro menu.
extras seemingly being InstantOn.kext & Rogue Amoeba Schedule Helper.app although perhaps others.
Find any File makes finding leftovers a little easier.

File Type Associations Do Not Stick System-Wide CS4

When I set File Type Associations for PSD, Tiff, DNG and Jpeg fles in Bridge CS4 so that my files will open in PS CS3 (and insure that the same file associations apply in Bridge CS3), this works as it should from within CS4 and CS3, but it is impossible to introduce a system-wide change in Mac OS 10.5.5 via File-Info. It always reverts to CS4 for these file types, if I try to 'modify all'. The same thing happened when I upgraded from CS2 to CS3.

If File Type Associations are set properly in the Bridge preferences, the default setting can be made to open files in PS CS3, with CS4 installed. This works from within CS3 and CS4. However, it sometimes happens that one is in the Finder, and the default remains PS CS4, however much one tries (via File-Get Info) to modify the default system-wide settings so that these files open in CS3. In any event, a bit invasive. Of course, if I could get comfortable with the Adjustment Layer Panels, all this would be unnecessary, but for the moment, there appear to be too many clicks, and it is going to take some time, so I don't want to burn bridges. Perhaps there is also some ambiguity in my mind as to what the pointing finger in the new Curves dialogue box, much like a tolling bell, is trying to tell me.
But thanks, once again Anne, for your good-natured help.

System-wide spell check will not work

Hi,
I can't get the system-wide spell check to work on my MacBook Pro with the Command + Shift + ; (semicolon) keys. Does anyone know of a solution to this problem? The Spell-Check on the Fly will work.
Thank You,

I was able to zap the pram and that solved the problem.

ITunes 10.7 crashes all apps on Mountain Lion including Force Quit. First system wide prob with an apple computer since OSX introduced. Any ideas?

updated to iTunes 10.7 from app Store last night. After the update, iTunes opens then stalls with the "spinning pizza wheel". Force Quit is unresponsive and will not shut it down. If I then open other applications say Safari for example, the problem migrates over to Safari and it similarly stalls and becomes unresponsive. The only way to solve the problem is to manually shut the computer down. This is the most significant problem I have experienced on an apple computer since OSX was introduced because it impacts on Force Quit which means that you have to shut the whole deal down. There are obvious problems for use of Apple TV and apple store etc. ! I am running mountain lion 10.8.1 on a 27" iMac with 2T Time Capsule connected wirelessly. How do I downgrade iTunes back to 10.6? I had no problems with Mountain Lion or iTunes up to that point.

this is the exact same problem i've been dealing with for the past 2 days. after i installed itunes 10.7 for my iphone5 it would crash my mbp's lion system wide. i tried every solution i could find on google and i've actually had to reinstall lion & time machine my backups because of it. right now i'm too scared to redownload itunes 10.7. i actually feel like waiting for the "new itunes" that comes out in october.

Is there any way to create a system-wide variable?

Hello IDM gurus.
Is there any way to create rarely changing system wide variables that can be loaded at system startup that will be available to all users? For example, at IDM system startup, the variables would be read from configuration or generic objects and live in memory for ALL users as opposed to each workflow/user having to read the same variables when the workflow is run.
Any help would be appreciated.

That may very well be the answer I'm looking for. Is there a way for that to be available within the entire application instead of having to read it in each workflow?

Setting ALSA sound card system wide (rather than just in KDE)

Hi,
I've got an HTPC with an ATI Radeon HD 4350 graphics card running Arch x86. It has its own integrated sound card for outputting audio via HDMI, which is detected by ALSA as a separate device. I've managed to set it as the default audio device in KDE 4 (via System Settings). This allows applications such as Amarok and SMPlayer to properly output audio to the HD 4350's integrated sound card, but software such as Flash and MPlayer (from the command line) are still outputting audio to the motherboard's built-in sound card. How can I change this setting on a system-wide level? I've tried running alsaconf as root and adding
pcm.!default {
type hw
card 2
device 3
to ~/.asoundrc; I got the card and device numbers from aplay:
[htpc@exia ~]$ aplay -l

No, I haven't tried that. I'll give it a shot. Thanks for the tip!

Non-system wide DNS Lookups on RBL (i.e. logical groups supported)

Sun Java System Messaging Server documetation seems to state that RBL filtering can only exist in one of three files that are used for filtering based off of inbound connection IP address. My question is, can conditional execution occur for a section of one of these files based of destination e-mail address?
I'd like to have multipule levels of e-mail filtering using RBL and allow users to be assinged to the level of filtering they desire by joining a logical group which will enable a level of RBL filtering for that logical group.
Any help is greatly appreciated, as far as I can see, I can only have one system wide filtering set, so I can't possibly have one set of e-mail ids using 10 RBL (remote black lists) and another group e-mail ids using a smaller set of RBLs.
======= From the documentation =======
MAIL_ACCESS : Used to block incoming connections based on combined information found in SEND_ACCESS and PORT_ACCESS tables: that is, the channel and address information found in SEND_ACCESS combined with the IP address and port number information found in PORT_ACCESS.
ORIG_MAIL_ACCESS : Used to block incoming connections based on combined information found in ORIG_SEND_ACCESS and PORT_ACCESS tables: that is, the channel and address information found in ORIG_SEND_ACCESS combined with the IP address and port number information found in PORT_ACCESS.
PORT_ACCESS : Used to block incoming connections based on IP number.
====================================

Alas, the RBL stuff is done before iMS even knows who the message is addressd to. That stuff is done at the initial connection phase, as our philosophy is to reject a message just as soon as possible . . .
After the message is accepted, then you can opt-in/out for things like spamassassin, brightmail, etc.

FDM System-wide

I tried using FDM and i love it. However, I did a thorough Google search and this forum for a solution to my issue but could not find any answer. I hope someone will be able to assist me with a solution.
Am wondering if it is possible for FDM to fetch mails from an ISP Domain box (multidrop/catchall mailbox) that holds mails for several users , and then hand them to Postfix that has Dovecot LDA delivery configured. The mails will then be delivered (by Dovecot's LDA) to respective users. I use Fetchmail (that is able to do this), but there are some issues with it, (like sometimes it gets stuck on large mails, etc).
Here I illustrate my current Fetchmail System-wide setup's /etc/fetchmailrc file:
# /etc/fetchmailrc
set postmaster [email protected]
set no bouncemail
set daemon 300
set logfile = "/var/log/fetchmail.log"
poll isp.domain.com proto pop3
localdomains abc.net
no dns
no envelope
user domain_mbox_username
pass domain_mbox_passwd
is * here
In the above fetchmailrc, "is * here*, * is aliased to our catchall account in our local postfix server. The ISP domain mailbox is configured as a catch-all domain and it holds our users emails (several different email addresses but all "@abc.net")
I couldnt find a way to do this with FDM since I am limited to delivering to mbox/maildir directly, and the way I understand it is that I would have to create individual inbox references. This would be tedious if we have some hundreds pop3 local mailboxes, ( I might be wrong in my assumption).
With my current setup, aliasing to the catchall account automatically distributes to respective mailboxes by reading the mail headers. (and also am not very good in coding, please treat me like a newbie )
Looking forward to your assistance.
Thanks and regards,
Clemo

W2K8 & Win7 - Setting system-wide Trusted file locations not working

Win 2008 Network, Win 7 workstations.
RE: Setting system-wide trusted file locations
I have an application using Flash stored on a network location that accesses other files in the same location. This causes the security warning "The following local application... is trying to communicate with this internet-enabled..." I can add the location to the trusted sites in the Setting Manager and the warning goes away. It is not practical however to do this on every machine on the network. I have tried the FlashPlayerTrust directory and mms.cfg file and neither of these seem to work. Is there a trick to getting the FlashPlayerTrust directory to work properly. If I could get this working, I could create a script that copies this file to all machines on the network.
Any help you be greatly appreciated.

Hi Todd,
Can you please provide just a little more detail?
* When you say "accessess", what API is being used? Are the paths to the other files relative, file: URI http: URI, other?
* In the FlashPlayerTrust directory, are you using the same path notation as appears in the Settings Manager? What's a sample {filename}.{ext} being used?
Thanks!

System Wide Text Substitutions

I hope this is the right discussion group for this question. I just discovered that 10.6 has the ability for applications like Text Edit to use automatic text substitutions so that if you type "teh" by accident it will automatically change to "the". This is a great feature since any single "i" will become "I" and so on. You can progran whatever you like. In word processors this would include auto capitalization etc.
Can anyone tell me why this feature does not work for Mail? I am certain more users use Mail than the y do Text Edit (a great programme by the way).
Does Apple intend to extend this feature to Mail in the future. It's always been a problem for me since I use Outlook at work and it includes all those features as part of the Office thing (including auto capitilization). It would really help the workflow of Mail if one could automate some of this stuff.
Thanks

see this link how to enable it system wide. I use it in Mail. very handy.
