Since this is not a defect in the TurboTax software, but is due to a change that Apple made which causes an internal Apple java script function to crash while reading an embedded java script component in the TurboTax application, TurboTax will not be issuing any update to the TurboTax software. That is a known issue that seems to have been created by Apple with a change in OSX 10.13.4. TurboTax 20 crash on Mac 10.13.4 (and later). Also, be aware that if your Mac OS is 10.13.4 or later there is a known crash issue with 2015.
