My iMac desktop keeps freezing on my. Here is the EtreCheck report.

Mac Basics: Time Machine backs up your Mac

If a standard permissions repair and disk verify does not reveal any issues, then do these steps:

1) Download and Mavericks combo update to ensure no critical OS files are missing or corrupt:

http://support.apple.com/kb/DL1755

2) Run this command at terminal to make sure all your Spotlight processes are running correctly:

sudo launchctl list

Check and see if the following things are in the list:

com.apple.metadata.mds.plist

com.apple.metadata.mds.index.plist

com.apple.metadata.mds.scan.plist

com.apple.metadata.mds.spindump.plist

If they are not then issue these commands on the terminal then restart:

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.index.plist

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.scan.plist

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.spindump.plist

<reboot>

Then do sudo launchctl list again and make sure they are now running.

3) Rebuild all your Spotlight indexes. Mavericks is notorious for these getting corrupted, and it can cause your disk errors (believe it or not).

sudo mdutil -Ea

Let me know if that helps you, or not.

THE MAC DADDIE

SINCE 198 FRICKING 4

Collection of Macs that I own:

Mac 128k, Mac 512ke, Mac Plus, Mac SE, Mac SE/30, Mac Classic II, Mac Color Classic, Macintosh Portable, Mac IIcx, Mac IIci, Mac IIfx (x3), Quadra 950, Power Macintosh 8600/350, Power Macintosh 9600/300, Power Macintosh G3 (beige desktop), TiBook 550, iBook G4 1ghz White, MacBook Pro mid-2012 16gb/2.4ghz, Mac Pro 2009 2x8-core Xeons 2.26 ghz, a few old Mac Clones (Umax and Supermac), original Bondi Blue iMac, red iMac DV 450 mhz, and a Hackintosh. I'm probably forgetting some

The thing you have to wonder is why your HDD died in the first place. Think about it: if your spotlight is endlessly indexing forever all the time, for example, that's constant wear-and-tear on the HDD.

In our case the freezes ended up actually being related to Google Drive. As soon as we removed Google Drive from the system all was well!

I notice you had both Logmein and Teamviewer installed. If you had a valid use for them - great - ignore the rest of this comment.

Those two apps can be used by unscrupulous/scam "help desk" services to control your Mac. Did you ever allow someone else to take control of your Mac?

Not a good idea. Next time, come here for help First!

Team viewer includes a full uninstaller, it is thorough. Don't know about Logmein, check their website

On our iMac I fixed all the disk0s2 io errors by deleting the spotlight index and removing all third party items from the following folders in both /Library and ~/Library:

LaunchDaemons

LaunchAgents

PreferencePanes

StartupItems

InputMethods

Spotlight

Internet Plugins

Also add your drive to the list of excluded Spotlight folders so it won't reindex. Put it back later when the coast is clear.

Also remove every Login Item in Users & Accounts.

Apple really needs to reintroduce the Extension Manager from OS 8.x and 9.x. It is really getting ridiculous. One wrong item in any of these 26 different places can totally hose your system. In my case it seems to have been Google Drive, which also hosed some other folks, although it may have been helped along by an old iPhoto Icon Helper plugin or some crap. Then the caches get corrupt and every time you restart it wants to re-open every app and freezes again.

Os X should be smart enough to realize when the machine has been force-powered off. In such cases it should not auto-re-open every app, but instead boot to a safe mode where it slowly starts each system service one by one, monitoring for performance hits, until it finally finds which one is the culprit. If your spotlight gets corrupt the system has know way to detect this and becomes unusable, and all the know-it-alls in this forum will just have you nuke the site from the genius bar and buy a new HDD. No these disk0s2 errors are NOT hardware related. It is caused by blocking code at the coreservices level causing system calls to the disk to time out and fail. Once you isolate out the problem process and clear out the bad spotlight crap and clear the app state caches then it will work perfectly again for months.

Also delete third-party stuff from Caches and QuickLook and Widgets... Also start up in recovery mode and reset your permissions from there. You can use the terminal there to delete all this stuff or at least move it to harmless locations. The primary problem is Apple needs to hire me to do quality control but they have not done so yet.
