After I re-install my computer I took a new subscription for Adobe Creative cloud.
Now Lightroom don't want to start. It said: Lightroom can make the map: /users/p.m.m.vergeer/library/Application Support/Adobe/Lightroom/Develop Presets.
I understand the problem....but how I can solve this problem easily?
Try resetting Lightroom's preferences by following the instructions here: https://www.lightroomqueen.com/articles-page/how-do-i-reset-lightrooms-preferences/. It's also possible that your permissions on that folder (map in het Nederlands) are set wrong. You can try resolving that in Finder. You can get to the folder by choosing "Go->Go to Folder" and entering ~/Library/ in the dialog. You can then navigate down to the folder mentioned in the error message and doing a command I on it and checking whether your user has write permissions on it.
I try everything...but Lightroom said he can not make the map....I really don't understand why not...
