iMac Pro (2017), macOS Mojave 10.14 Graphic Rodeon Pro Vega 64
I installed the new version of Lightroom Classic CC, but when I tried to start Lightroom, I got permission issues. Then I tried every suggestion including changing the password that you suggest in your page. Unfortunately I still have the same problem. I uninstall the Lightroom then reinstall, that also did not work. So I went back and reinstall the older version. Any suggestions?
Mojave may be asking you for 'permission' for LR to access your drive, a new security feature.
If so, go into System preferences>Security & Privacy>Privacy tab. Click to make changes (as Admin), then click the Plus button to allow apps below to control your computer and select Lightroom and other applications that ask for this access. Done, you'll not be asked again.
