QuickLookSatellite MAC OS, High CPU Use

QuickLookSatellite MAC OS, High CPU Use.  Restarting does not even fix this problem.

Troubleshooting steps:

  • See if there are any relevant log messages in Console.app or /var/log/system.log.
  • Use qlmanage -r to reset Quick Look client’s generator cache.
  • Run sudo opensnoop -n QuickLookSatellite-general to see if the process hangs after accessing some specific files. Or select QuickLookSatellite-general in Activity Monitor, press command-I, and see the Open Files and Ports tab.
  • Temporarily delete Movie.qlgenerator, Audio.qlgenerator, or other qlgenerator bundles in /System/Library/QuickLook, and run qlmanage -r.
  • Temporarily remove applications shown by qlmanage -p | grep /Applications/.
  • Disable quicklookd with launchctl unload /System/Library/LaunchAgents/com.apple.quicklook.*. The plists are loaded again after you log out and back in.

If nothing else works, you could try doing an upgrade install of OS X from the recovery partition

Nasa Johnson Style? [Gangnam Parody]

NASA Johnson Style is a volunteer outreach video project created by the students of NASA‘s Johnson Space Center. It was created as an educational parody of Psy’s Gangnam Style. The lyrics and scenes in the video have been re-imagined in order to inform the public about the amazing work going on at NASA and the Johnson Space Center.

What is Windows RT? It’s not Windows!

This quote from Paul Thurrott’s Supersite for Windows, pretty much needs to be stressed.

Windows RT will not run any desktop applications beyond the applications that are bundled with the operating system. This means it will not run Windows Essentials 2012, Microsoft Outlook (any version), Microsoft Office (any version, beyond what’s included with RT), Adobe Photoshop or Photoshop Elements, or any other Adobe desktop application. It will not run the SkyDrive desktop application (which is part of Essentials 2012, yes, I know), meaning you cannot sync SkyDrive data to your RT device’s storage. You can only use the SkyDrive Metro app, which lets you access SkyDrive only when connected … just as with any other mobile device. It will not run iTunes. It will not run any desktop Windows application beyond what’s bundled with the OS.

Windows RT is not a computer operating system. Windows RT is an operating system for mobile devices.

Surface with Windows RT is not a computer. It is mobile computing device, like an iPad. It is a tablet, a hybrid device that bridges the gap between real PCs and media tablets, where you can work and play.

Now I’ll return to the reference to the iPad in a few minutes….

Microsoft is attempting to mislead users into thinking that Windows RT is a special version of Windows 7/8.  They believe that since it’s Windows, they’ll be able to use Windows 7 or Windows 8 software on it.  That’s simply not true.

With the iPad, Apple has never said it’s running Mac OS X, and that you can use desktop software on it.  Microsoft says, you’ll be able to Office on the Surface, without qualifying it’s Office home & Student 2013 RT.  Never mentioning that it doesn’t include Outlook, nor the ability to connect to the Exchange server at work.  (Exchange connectivity on the desktop requires Office Professional.  The Student version of Office does not allow connectivity to an exchange server!)

So, let’s return to the iPad comment.  The way it’s worked makes it sounds like the iPad lives in the same limited world that Surface RT does.  Yes, it’s true that you can’t take your Office CD/DVD and run it on the iPad.  But with the existing developer’s community, and with the fact that there is now over 650,000 apps in the App store, I think the comment is biased and misleading.

Spotlight hogging your processor? MDS running Amok?

Having trouble with your system Bogging down? Take a look in the Activity Monitor and check the CPU load for MDS and/or MDWORKER.

Are they consuming a large portion of your CPU?

If so, here’s some hints on how to debug this situation….

If you use this unix command

sudo fs_usage -w -f filesys mdworker | egrep “open”

Alternatively, this command which will show all open files from the MDS process, might help as well.

sudo fs_usage -w -f filesys mds | egrep “open”

You will see every file that mdworker is opening. This will allow you to see what files maybe handing up MDS / MDWORKER….

Once you have an idea on what files could be causing an issue, exclude using the Spotlight Privacy Pane. This allows you to eliminate them without having to delete the file(s) at this time….

But keep in mind, this issues may not be a spotlight issue, it could be a Time Machine issue. There are situations where Time Machine takes a long time to index, and can cause a situation where Spotlight revisits the same files…

Invalid Context? Let me explain, it’s Safari’s Fault!

Well, have you seen this error message in your console log?

10/3/12 11:52:09.869 AM Safari[71558]: CGContextClipToRect: invalid context 0x0

Symptoms can include Safari running slow, showing the spinning beachball of doom for a while, and in some cases Safari just plain crashing…

Well, my investigation points to it being caused by an out of date Safari extension. Open Safari preferences, click on Extensions, and take a look to see what out dated, or unused Extensions you have loaded.

Disable all non-essential extensions, close Safari, and then re-open Safari. See if your Safari experience is any better….
