Below you will find a list of possible issues you may find running Painter 2018 on macOS 10.13
- On macOS 10.13 with APFS, brush categories and brush variants will not appear in alphabetical order.
This issue has been fixed and will be released with the next update of Painter 2018.
- The Corel Painter installer includes a kernal extension, the Internal Audio Driver, that is affected by the new secure kernel extension loading feature on macOS 10.13 which requires that only kernel extensions approved by the user are loaded on a system. If at the end of the installation there appears a System Extension Blocked OS message, chose System Preferences > Security & Privacy, and allow Corel Corporation to load the Audio Driver extension.
This may be seen when installing Updated (or GM) depending on if the user does a new install onto 10.13 or a migration
