Hi,

To add to @aha_1980, what version of Xcode are you using to build your project ?

[davecotter]

@aha_1980 note on mac it's not at "tools->options->Kits->Kits", it's at "Qt Creator->Preferences->Kits->Kits":

@SGaist i have Xcode 9.4.1 but the OS keeps insisting i install command line tools for 10.14, (which i did) which may be related?

[aha_1980]

@davecotter and can you select another compiler in this dialog? At least the gcc looks wrong
