I'm having problems installing plug-ins for Adobe XD and I got redirected to the right location but the problem is, I can't delete to file.
Before renaming/Deleting the file, please end all Adobe related processes from the Activity Monitor. Once renamed/Delete, please reboot and check again and let us know how it goes.
I would like to follow up on the issue. Would you mind confirming if your issue has been resolved by following Vertika's suggestion? If no, please let us know if you're getting any error message while installing plugins.
We will try our best to help.
