It’s definitely not a Yosemite specific problem - because I had the same issue with SketchUp Pro running on Mac OS X:
Saving and opening files mostly lead to a crash of my SketchUp Pro installation.
Some examples (and workarounds):
Creating and saving a new file … normally crashes before the standard Mac file dialogue appears.(DATALOSS)
Only workaround, so far: Save the file right after opening it without doing anything in SketchUp. If I create some 3D stuff after saving the pure new file I can save those changes … most of the time Sketchup also crashes, but just after saving the SketchUp file.
Saving an existing file … normally crashes after the file is written to the disk.(NO DATALOSS)
Workaround: Be sure that you always only need to save one of your open files … as the other files will be doomed with the crash.
Save-As an existing file under a new name … normally crashes before the standard Mac file dialogue appears. (DATALOSS)
Workaround: Create a duplicate of the file you want to “save as” in the finder and open it in SketchUp … then you can just save it. This also crashes Sketchup … but as said before: it crashes after saving.
Second Workaround: If you already changed the SketchUp-file, but want to preserve the old file, you switch to the Mac Finder, duplicate the file you are working on right now. Then you just use the save command in SketchUp. SketchUp will crash after saving the file. So now you can rename the two files so that everything is ok again.
Import file … bringing up the standard Mac dialogue mostly leads to a crash. (DATALOSS)
Workaround: Sometimes it helps to open the SketchUp-file, save the file and then go on with the import.
Things I did to solve the problem, but did not help:
- Repaired file permissions on my Mac.
- Deleted all SketchUp-related preferences.
- Reinstalled SketchUp Pro 14.
- Mac OS X 10.10 (14A388a)
- SketchUp Pro 2014 14.1.1283
