All Graffix plugins for Adobe Illustrator are now optimized for Illustrator 2020 for both Mac and Windows, and available for download, with the exception of ServerLock. That update is in progress. IsoTool is not updated, but its functions are now built into AxoTools — The drawing tool from IsoTool will continue to work for free in AxoTools without licensing.
I’m happy to report that all Graffix plugins (except for ServerLock, for now) are notarized for use with macOS 10.15 Catalina, Apple’s new all 64-bit OS. This applies only to plugins compiled for Illustrator 2019 and 2020.
In the meantime, here’s a workaround for older versions and — temporarily — for ServerLock. I won’t go so far as to say that I recommend this, but both have worked for me and for other users.
All Graffix plugins for Adobe Illustrator are now compatible with Adobe Illustrator CC 2019. Updating the icons and cursors for ultra high-res screens is a project in progress, but for now the plugins are compatible and the UI scaling works. If you have any trouble loading or using the plugins in CC 2019, please let me know and I’ll do everything I can to get you running ASAP.
