Is there any way to exit out of the dialog, to interrupt the processes of Select and Mask? Because there is still some fundamental issue with the coding within Select and Mask dialog on mac -
For example - at the moment I've a file open, which I spent an hour on, (not saved yet sadly) and I mistakenly, oops, launched Select and Mask forgetting the file size. Total freeze, it's churning through some step-by-step process as if it was 1995 precessor speeds, and there was single-core processor. Activity Montor tells me that it is still chugging. It doesnt actually crash Photoshop completely now, granted, it will eventually recover sometimes, taking a long time. When you have deadline (in my field deadles can be minutes) its tortuous to have to make a decision bewteen losing all your work, force-quitting the whole app, just to restart and get perfomance up again.
Here's the clues - and why I'm cofident in saying 'poor fundamental structual design decisions within S&M dialog" (since the beginning, sorry Select and Mask people, but this dialog ain't ever worked properlt)'
1. Graphics card is not involved, so it is not a GPU preference issue as peopke have answered in the past. It is possible to switch out of photoshop aand all apps work perfectly, while this whole process is going on. Going in and out of photoshop works seemlessly. If GPU were involved in any way this wouldnt be happening,
2. There's is some confusion between display issues (what the dialog os showing you of your image), and perfomance of the tools, thy sould not be linked, not deteriorate either in any way. They should now certainly be using diffrent parts of the processor.
3. Wacom issues persist, there is hesitation while the driver or cursor hesitates and jogs around.
I'm on latest Photoshop, but still running Mojave. Have to, Please don't hit me.
