Issues with Select&Mask and Onion skin
I have just recently (a few days ago) upgraded my iMac to OS Sierra and Photoshop CC 2017.
When I try to use Select and Mask two things definitely refuse to work: Onion Skin option can be selcted but nothing happens when I try to select the areas on the image, and the seleztion tool itself doesn't work.
Other options, such as on white, on black and refining tools seem to work, but first I am forced to make a selectino BEFORE invoking select and mask, and secondly the Onion Sking feautre is not working.
And yes, although I am aware that many other complained, the refining tools work very poorly, lengthening the process.
I have read quite a lot of thread, but apart from using refine and edge from previous PS version or deinstalla and reinstall (which I defenitely DO NOT want to do), no clear answer came up.
Is there any upgrade in the making from Adobe to overcome these problems?
Thank you in advance for any help
