Select and mask tool not working CC2017

Guess I will call Adobe support because I have tried everything everyone suggested on here, and now my laptop  photoshop home screen is just blank. There are no tutorials there like there used to be now that I changed the preferences.

My select and mask has never worked at all.  I had a labtop,  so I thought maybe that was the problem even though the labtop was quite sufficient enough to handle the task. Anyway, I purchased a desktop and it still doesn't work !! I can see the selection, but none of the tools work- they don't do anything. Not like what they are supposed to, what I have seen them do in tutorials, etc. This is so frustrating, I pay monthly for adobe and I went out and spent quite a bit of $$ on this desktop when there wasn't anything wrong with my laptop all for this to work and it still doesn't. Does anyone have any suggestions ?? Is the refine edge one of the tools in the select and mask on the left hand side? If so, none of them work, none of the sliders  on the right hand side, only the view mode works.

Been going a while, but I finally sussed (after lots of head scratching, searching and faffing) that to be able to preview select and mask refine edge, you have to set opacity to 100.

I am also having the same problem. It will not work on a file with layers but will work on a single layer file. Deleting prefs did not work. Come on Adobe sort this out!

Try unchecking Show Original (P) in Select and Mask

Hey! I talked to this guy named Marco from Adobe, and he made me to restart the preferences. Then the problem was quickly fixed.

For anyone who has the same problem, this are the steps to restart the preferences:

Hope it is helpfull as it was for me!

Hi! The tool doesn´t work. I´ve tried everything. When I make the selection and use the tool, then I click OK and no mask appear.

One solution I just found was changing the colour space – my image was set to RGB/8# which resulted in the Select and Mask not working. changing the image and assigning a colour profile, suddenly made Select and Mask work again.

Also not working.  I have a Wacom installed but was not using it.  Photoshop becomes unresponsive and I have to end task.  I had a mask on a group and clicked on mask to adjust it.  Made one small adjustment and photoshop became non-responsive. I'm using PS CC 15.5

I have the same problem, when i use "select and mask" my photoshop freeze after 10 seconds, i can use it with alot of lag for 10 seconds, but after that it freeze and i cant do anything to it. I use windows 10 x64 with a waom intuos pro large, and in task manager it doesnt show photoshop as "dont respond", it is working as normal, taking normal usage from my machine, so this freeze is not recongnized as an error, it just makes photoshoop freeze and all i can do is "end task". I keep using it with a mouse becouse i really need this option, but i need to unplug the tablet when i do it, and its verry unacurate using it this way, but at least is working. Please, if anyone knows a solution will be much apreciated!! i dont even know, is a tablet problem, or a software, or what? is it from wacom or from photoshop? can someone elight me with some infos about this please?
