MacOS – SiLabsUSBDriver.kext

I try to do what I can, unfortunately I did not exactly 10.8, I would like to point out that the following list is for

System Version: OS X 10.9.3 (13D65)

Audio.qlgenerator Bookmark.qlgenerat Clippings.qlgenera Contact.qlgenerato EPS.qlgenerator Font.qlgenerator Icon.qlgenerator Image.qlgenerator LocPDF.qlgenerator Mail.qlgenerator Movie.qlgenerator Notes.qlgenerator Office.qlgenerator PDF.qlgenerator Package.qlgenerato SceneKit.qlgenerat Security.qlgenerat StandardBundles.ql Text.qlgenerator Web.qlgenerator iCal.qlgenerator iChat.qlgenerator

Then in addition to /System/Library/QuickLook/ there is also /Library/QuickLook/ where I found: iBooksAuthor.qlgenerator iWork.qlgenerator

It's the kernel extension for JMicron SATA controllers, and yes it's official, as are the others. It's up to you if you want to delete them, I wouldn't bother as they take up minimal space. Check System Profiler before doing anything silly just to make sure your iMac doesn't require any of the listed extensions.
