Did you know that most issues with SketchUp on a Mac can be solved in one of two ways?


If you run into an issue with SketchUp on the Mac, and things seem to be acting strange, features are missing, or things aren’t running the way they used to, there are two very common troubleshooting tactics that can put things back in the right order: Repair disk permissions, and reset SketchUp’s preferences file.

[Repair Disk Permissions]

  1. Restart your computer.
  2. Open a Finder window.
  3. Click Applications.
  4. Click Utilities.
  5. Double-click Disk Utility.
  6. Select your hard drive.
  7. Select the First Aid tab.
  8. Click Repair Disk Permissions.
  9. Please repeat step eight until you no longer see new errors during the repair. After the permissions a are repaired, exit Disk Utility.

[Reset SketchUp’s preferences file]

  1. Close SketchUp.
  2. Open a Finder window.
  3. Click Go in the top menu bar, press and hold the Option key, then click Library when it appears in the list.
  4. Click Preferences.
  5. Click and drag any of the following files, if present, to the trash:
    a. com.atlast.sketchup.plist
    b. com.google.sketchuppro.plist
    c. com.google.sketchuppro7.plist
    d. com.google.sketchuppro8.plist
    e. com.google.sketchupfree.plist
    f. com.sketchup.sketchup.plist
    g. com.sketchup.SketchUp.2014.plist
  6. Launch SketchUp.

And that should do the trick!

Crash after updating Mac OS X
OS X Yosemite testers?
When I export to jpeg, the object seems as lines

Layout Not Overwriting when Exporting PDF Yosemite

I think after deleting the plist file you also need to empty your trash.



Is there a way to repair permissions on an external drive, or am I betraying my ignorance?


When using Disk Utility you have the ability to chose the drive that’s being repaired, however, Repair Permissions only works on a system disk. If you an external drive with the full OS on it, and you boot up using that drive then you can repair permissions, otherwise there isn’t an option.

Note that installing SketchUp on an external drive may not be something we can support and if we were to start troubleshooting problems we would start by moving SketchUp to the proper Applications folder to confirm if the problem persists.

Hope that helps!

even that won’t always work… osx now stores some sort of backup copy of .plists and if your timing isn’t right (lucky), the trashed and erased .plist will still come back… the surefire way to reset to default configuration is through terminal.app (Applications->Utilities)

quit sketchup and enter this in terminal:

defaults delete com.sketchup.SketchUp.2015

(or whatever .plist you’re attempting to reset)


Thanks Jeff - saved my bacon ! Spent a while yesterday trawling round for solution - you nailed it.



Even simpler sometimes: I just repaired a mysterious permissions issue by just restarting the computer.
