On checking for updates, CC is saying my LR 2015 is up to date and will not find the 2015.7 update. I have updated Camera Raw but not LR. I'm running Mac OS X Sierra on a Macbook Late 2011.
A friend told me there was an issue that could be resolved by removing a file from system files so the update can be detected. Does anyone know how to fix this issue? I need to update LR to read my Canon 5D Mk4 files.
Just do a regular uninstall, reinstall, like you'd do with any other program.
