I've had these same issues the last couple of years.
Here is how I fixed it again this year.
Once you have the software installed and it keeps crashing then go to the GO menu, hold how the Option Key and select library.
Delete the following files.
- ~/Library/Application Support/TurboTax 20XX
- ~/Library/Caches/com.intuit.TurboTax.20XX
- ~/Library/Caches/TurboTax 20XX
- ~/Library/Preferences/com.intuit.TurboTax.20XX.plist
- ~/Library/Preferences/com.intuit.TurboTax.20XX.LSSharedFileList.plist
- ~/Library/Saved Application State/com.intuit.TurboTax.20XX.savedstate
- ~/Library/Cookies/com.intuit.turbotax.20XX.binarycookies
- ~/Library/WebKit/com.intuit.turbotax.20XX
- ~/Library/Containers/com.intuit.turbotax.mac20XX
- (This folder will only appear if you installed from the Mac App Store instead of a CD or download.)
- ~/Library/ApplicationSupport/com.apple.sharedfilelist/com.apple.LSSharedFileList.ApplicationRecentDocuments/com.intuit.turbotax.20XX.sfl
- (This folder will only appear for OS X 10.11, El Capitan.)
Once you've removed those files and folders:
- Empty your Trash.
- Check first to that there's nothing in Trash you want.
- If you get any errors deleting the above folders from Trash, restart your Mac and empty Trash again.
- Reboot your Mac
- Start TurboTax and then enter in your serial number.
- There is something wrong with the App again this year if you enter the app before the software is installed.
- Hope this works for all.
