I have been using Topaz Sharpening AI for several years. I'm ready to jump ship. Mac OS Sonoma now has a bug using it with the new silicon based Macs, leaving it basically unusable. When you open it it flickers on and off continuously. On help forums Topaz representatives have admitted that there will not be a fix for this because they have stopped supporting it because they want everybody to switch to their latest software (Topaz Photo AI, $200) which combines their "old" noise reduction, sharpening, and enlarging software. I am sympathetic to software companies who need to innovate and have a viable revenue stream, but I think stopping support for a product after a little more than a year is too extreme. And yes, I know you can use LR or Photoshop sharpening tools to get the job done, but after using Pixel Genius and then Topaz (when PK stopped working on my new Mac) I have become lazy. Press a button, look at the changes, turn the opacity down if necessary, mask out areas as needed, and I'm done. So easy. So I am wondering if anybody can recommend an alternative to Topaz for sharpening. Thanks.
