I am enquiring on behalf of a client who has a SketchUp Pro 2020 licence. He was previously using SketchUp 2019, however install of 2020 keeps failing. Mac is running 10.14 Mojave. It appears that installer silently exits without error message.
The user had raised a support call and has emailed SketchUp support multiple times, but has received no reply at all. Hence my asking here.
Can anyone advise what to try next?
