Make sure you're downloading the latest version, 5.2.3. 
I tried uninstalling SketchUp Make 2017 and trying again, with the same kind of failure. I then followed SketchUp’s instructions on how to completely remove all traces of SketchUp from my Mac, rebooting and trying to install again.
This issue started as soon as I “upgraded” from 2016 to 2017 versions of SketchUp. I had opened SketchUp Make 2016, received a popup that a new version was available. I clicked the button to get the new version on the popup and the install seemed to go fine. As soon as I opened the new version (having already deleted the old version, my mistake) Bugsplat fired up immediately, though there was no window, just the icon in the Dock. I figured I’d see a window with a stack dump of some kind. Background I had originally downloaded and installed SetUp Pro 2016 and the 30-day trial had expired, where I was just using SketchUp Make.
Other Attempts I tried uninstalling SketchUp Make 2017 and trying again, with the same kind of failure. I then followed SketchUp’s instructions on how to completely remove all traces of SketchUp from my Mac, rebooting and trying to install again. Now SketchUp Make 2017 at least gives me the Start screen and allows me to click the “Start Using SketchUp” button before crashing and Bugsplat starting immediately. I’ve only got 256MB of ram and can’t even run Sierra on this machine but it runs SU v17 fine v17 is the only version that includes fixes for Sierra, so I’d be inclined to use AppCleaner.app to remove SU v17 completely re-download the latest version [from the 18th of October] open the DMG, drag the SU icon onto the Application folder icon open it the first time clicking Finder >> Application >> SketchUp 2017 >> SketchUp.app it should show the welcome dialog if you get a Bug Splat, send it in with some identifiable info i.e. Embeddedcrypticvapor and post the error code shown in safari, back here with a code someone can have a look for you john. John, I tried installing again, then fully removed using AppCleaner, then rebooted and installed again. Same failure signature.
BugsplatReporter is still not showing anything. Though I am getting these errors in Console: 12/5/16 10:50:23.449 AM SketchUp[504]: Error loading /Applications/SketchUp 2017/SketchUp.app/Contents/PlugIns/IfcImporter.plugin/Contents/MacOS/IfcImporter: dlopen(/Applications/SketchUp 2017/SketchUp.app/Contents/PlugIns/IfcImporter.plugin/Contents/MacOS/IfcImporter, 265): Library not loaded: @rpath/libifcplugin.dylib Referenced from: /Applications/SketchUp 2017/SketchUp.app/Contents/PlugIns/IfcImporter.plugin/Contents/MacOS/IfcImporter Reason: image not found Looks like IfcImporter Plugin doesn’t have all it’s resources available? Does SketchUp require Xcode? I’ll send in a ticket. Cleaned Console display and opened again trying to find other errors that may be causing my problem.
My Mac is filling so I have been looking around Inside ~/Pictures there are two large files: iPhoto Library Main.migratedphotolibrary and Photos Library Main.photoslibrary They are both about the same size After launching Photos the first time, I never went back to iPhoto I thought once I got Photos, iPhoto would not occupy any space Can I delete the iPhoto file? Is there anything I should be aware of? To make a backup can I just copy the pictures folder to an external drive by dragging in the finder, or is there a better way?
