unreal engine 5 projects not working in c++ after tahoe update

Hello!


I updated my Mac to tahoe and can't open an unreal engine 5 project with c++ (it works with blueprint). It worked before with the previous OS no problem. Besides, the Launcher does not recognise tahoe I have a project of a game with serious investment that can't work with since tahoe upgrade. Xcode doesn't work Any help will be very welcomed Thanks!

You neglect to say what was the previous macOS where you had no issue...



I would look for an update to your third party—if in doubt search the developers website or contact their: Support/Help/FAQ/Known issues/compatibility/updates…


Contact a third-party vendor - Apple Support

if this is all Xcode—https://xcodereleases.com


note:App Store submissions require current Xcode.

if it was an App store download...it should automatically updates the Xcode version
