Most of the changes made when upgrading to High Sierra are under the hood.
MacOS High Sierra introduces APFS (Apple File System) to Mac computers. APFS replaces Mac OS Extended (HFS+) as the default file system for solid-state drives (SSDs) and other all-flash storage devices, and this caused the plugin linking system within Fluid Mask to no longer call Photoshop successfully.
We have a fix that enables Fluid Mask to plug into Photoshop when operating macOS High Sierra. Please update your Fluid Mask with our High Sierra build which you can download here.
You can overwrite (replace) your previous build when installing. To then link to Photoshop, firstly please ensure neither Fluid Mask or Photoshop is running.
Then delete the plug-in aliases Photoshop has previously stored. In your applications folder, click on the Photoshop version(s) folder, then select the ‘Plug-ins’ sub folder. Delete any folder named ‘Vertus’ or Fluid Mask 3.plugin alias you find contained there.
You can now launch Fluid Mask as a free standing application, and go through the process of linking Fluid Mask to Photoshop again. A reminder on the process to do this:
From Fluid Mask’s menu bar, select, ‘Help’ , then ‘Enable Plug-Ins’. The version(s) of Photoshop you have installed and wish to plug into should be listed. Ensure the check box is ticked and hit ‘Enable Photoshop Plug-in’. When prompted, enter your administrator password. If your version of Phtoshop is not listed, please navigate manually to it’s ‘Plug-ins’ folder, as per the path listed above when you previously deleted old plug-in link.
Quit Fluid Mask and launch Photoshop, Fluid Mask should now be accesible via the Filter menu again.
