Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The procedure will help to identify which such modifications you've installed, as well as some other aspects of the state of the system that may be pertinent.

Here's a brief summary: Copy a line of text from this web page into a window in 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, paste again. Details follow.

You may have started the computer in "safe" mode. Preferably, these steps should be taken while booted in “normal” mode. If the system is now running in safe mode and is bootable in normal mode, reboot as usual. If it only boots in safe mode, proceed anyway.

Below are instructions to run a UNIX shell script. It does nothing but produce human-readable output. 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 damage. If you can't satisfy yourself that these instructions are safe, don't follow them.

Hi

I'm on macbook pro(2012) OS X 10.7.5 and few days ago it slowed down unexpectedly and intensely, even for basic operations like clicking on spotlight;

even now i'm in a trouble with typing that after clicking somewhere or typing a character its pointer goes to colorfull circle for waiting;really it's unusable since this problem has been appeared.

In the activity monitor there is no heavy processes or CPU usage but on Disk Activity there is huge spikes that i think its reason of slow performance,although there is no open app and utilized space is just 15GB of 750GB!

till now I've done some methods to solve the problem [SMC reset(3times till now),PRAM reset(2times till now),Verify Disk(that notified the disk is OK),Repair disk permissions(3times, that every time appears repetitive results with a lot of repairs) ].

Now after I read your guidance mentioned above, I've done it and want to help me;

The result of Terminal is:

Hi, Linc -

When looking for answers to my issues, I ran across this thread. It's from last year but I hope you can still help me. I am on an iMac, OS 10.7.5, 4 GB 667 MHz DDR2 SDRAM, 2.16 GHz Intel Core 2 Duo. There have been issues with running slow for quite a while but I could get it better by running disk utility (there are always a lot of repairs each time I run this). However, now my computer will just freeze when I am in the middle of something and has to be shut off. I had previously tried to uninstall a program that was suppose to help get my mac running better and ran into a lot of issues with it and am hesitant to do anything more than run disk utility now. I am hoping you can help. Thanks.

Consider uninstalling

Avast

CleanMyMac2

using the vendors uninstall instructions.

Both of these utilities can drain your system resources, for very little gain.

How does Mac OS X protect me?

<http://www.thesafemac.com/mmg-builtin/>

You may want to remove SIMBL as well.

FUSE can sometimes cause issues.

com.google.filesystems.fusefs

If you do not need this, you might consider removing it. I'm guessing it is associated with Google Drive, but that is a guess.

What are:

llels.kext.ConnectUSB (3.0.0)

etmac.driver.PocketMacKNet (2.0.0)

etmac.driver.PocketMacKSerial (2.0.0)

Do you need these kernel extensions?

I apologize, Bob. I have not had a chance to get back to this until today. I have attempted to uninstall both Avast and CleanMyMac but both seem to retain properties that keep showing up. When following the uninstall instructions did not work, I tried to go through and find everything associated with them but I am sure I did not find everything. I did find some of the ones that showed up on my previous post but whether I was able to get rid of them...

I have no idea what the kernel extensions are that you mentioned, and could not find them when I tried to search for them. I found SIMBL and removed it, but could not find com.google.filesystems.fusefs, or the kernel extensions.

I can usually follow directions very well but when it comes to the various libraries and what each have in them and where to find things, I guess I need explicit instructions as I felt quite lost in trying to find these things.

And of course, my computer still is freezing up and has to be shut down with the power button as the only option. It is better when I run 'Repair Disk Permissions' for about a week or so but then it starts occurring again. Each time it happens, there are LOADS of disk repairs to do, and I have no idea what I could be doing to cause them to occur.

Would you be kind enough to give me the paths where I can find the things I need to uninstall/remove, and I will try to see if that makes a difference?

Thanks!

NOTE: The correct way to uninstall something is to use the vendors uninstall instructions. But if you are going to go looking for this stuff manually, then they can be found at:

3rd party kernel extensions are stored in:

/Library/Extensions

3rd party Launch Agents can be in:

/Library/LaunchAgents

your_home_folder/Library/LaunchAgents

3rd party Launch Daemons can be in:

/Library/LaunchDaemons

3rd party browser plug-ins can be found in:

/Library/Internet Plug-Ins

your_home_folder/Library/Internet Plug-Ins

And of course, my computer still is freezing up

You should try booting into "Safe" mode to see if the system still hangs/freezes. In Safe mode most 3rd party items are not loaded. Safe mode also clears out some kernel caches which can be handy as well.
