Photoshop Elements 12 is hanging in OSX Yosemite.

Did you delete all preferences on upgrading before running PSE? That is critical with recent versions of OS X.

All preferences, as in the WHOLE preferences folder? Or just the ones having to do with Adobe?

Just installed Yosemite last night on an iMac and a MacBook Air.  In both cases on Yosemite, selecting the Lasso Tool caused the system to hang up and I had to force quit to get the system back.  This happened in PE11 on the iMac and PE12 on the MacBook Air.

If you have once run PSE it is necessary to also delete the saved application states.

So you would need to delete:

com.adobe.PhotoshopElements.plist

Adobe Photoshop Elements < version > Paths

Adobe Photoshop Elements < version > Settings

com.adobe.Elements Organizer. < version >.plist

com.adobe.ElementsOrganizer< version>.plist

and any lockfiles with the same names, then go to Saved Application States (at the same level as preferences) and delete any for PSE, then repair permissions and try again.

However, I will say that I am not running Yosemite (and don't intend to any time soon), but from the folks I knew who were in the Apple beta, it breaks many, many existing programs.

I am having the same issues after downloading OS X Yosemite last night.  SO FRUSTRATING!!!!!!!!

How to you repair permissions?

Go to applications>utilities>disk utility. Click the name of your hard drive in the list on the left side of the window, then click Repair Permissions. it takes a while so don't worry and don't get upset about all the messages scrolling past. They don't matter. Nothing to worry about unless at the end it says the repair failed.

Nothing suggested so far fixes PSE12.

One other trick I tried was holding down Shift+ALT+Command immediately upon launching the program. A dialog box pops up that asks you confirm resetting the application.

Adobe support states that PSE13 must be purchased for those using Yosemite. I purchased PSE12 just 6 weeks ago, so I am particularly annoyed with the buy new response from Adobe.

I can confirm that my ancient PSE6 works fine in Yosemite. I also read somewhere that PSE10 also works. So, this seems to be a PSE11/PSE12 specific problem.

@mwheinz.

That is what an Adobe representative told me in an online chat I had with them yesterday.

I have the exact same problem—contacted apple support to go back to original operating OS or whatever the heck it is…very unhappy with the entire situation

I guess Adobe is telling everyone go get a different App. They don't care about us who paid for their program. I am going to one of the FREE programs which didn't hang up

I updated to PSE 12 at the beginning of this year. They can forget my business anymore.

I have the exact same problem. Purchased PSE 12 less than a month ago, upgraded to OS X Yosemite yesterday & now it doesn't work. Bummer.

we should not have to jump thru hoops and be some kind of computer nerd techie to have our software up and running after the upgrade

i went on chat with apple yesterday about this—the kid offered no solutions, just retrograde back to mavericks—also offered no opinion about yosemite

i use photoshop in my very small business, and i guess i am going to have to lay out money and upgrade it to PSE13

It appears that the problem is with trackpads. Try using a mouse instead and see if it works for you.

thanks i will give it a shot

PSE6 works in Yosemite using the trackpad.

I read that PSE10 work in Yosemite, but I do not recall if that person who made the claim stated they were using a mouse.

Someone stated the PSE11 allows making a single click, and it does not entirely lock PSE.

PSE12 I know makes a single click and locks the app.

The problem is somewhat odd. A partial trackpad error was introduced in PSE11, and the error became worse in PSE12.

PSE13 is claimed to work fine in Yosemite by Adobe, but a user needs to confirm the latest version works when using a trackpad.

I bought the upgrade from PSE 12 to PSE 13 and am using it with no problems on Yosemite with a trackpad.  There seems to be no answer to the issue other than getting PSE 13.  Just don't get 14 or 15 and you can amortize your cost over three years!

Thank you for confirming PSE13 works.

In my case, I bought PSE12 at the end of August 2014. Six weeks of use is not an acceptable solution.

I can use PSE 12 with my mouse but not my pad.

This is an Adobe problem they will not address. So I am now going to look

at other products that are not from Adobe. I just can't trust them any more.

Exact same issue here after upgrading to Yosemite over the weekend. No problems except 2011 iMac's Magic Trackpad and 2013 Macbook Air's built in trackpad both cause PSE 12 to immediately freeze when using tools. PSE 12 works fine with a Magic Mouse. The touchup and clone tools in PSE 11 which I have retained to run my 32-bit scanner are functional with trackpad clicks but dragging the brush doesn't work. The application doesn't freeze however.

If PSE 13 tools work with trackpads, that tells me this is probably an Adobe issue.

since i appear to be stuck with yosemite, and i refuse to pay to upgrade to photoshop 13 ( its not the money its the principal), i am currently shopping for new editing software…just got Pixelmator….doesnt do what photoshoppe does, but then, i don’t really have a need for a lot of the stuff photoshop offers…not a pro so i am not going to invest in the upgrade…also,   how in the world has photoshop gotten by not responding to this?

I have heard that the company has gone down hill over the past few year I

guess this supports what I heard.

they techie nerd hotshots at apple should upgrade aperture to adopt certain photoshop elements at a reasonable price—thereby keeping it “all in the family"

Isn't it odd how we're all having PSE12 freeze issues just when PSE13 comes out. One has to wonder if this is their way to get people to pay and upgrade.

I have a separate mouse and I cannot get PSE 12 to work for me – I downloaded the trial version of PSE 13, and when that is up, I just might be forced to upgrade to PSE 13.

Adobe & Apple, you both suck.

I switched to using my mouse instead of my track pad, and it works! This does not make any sense at all!

Are you hearing this ADOBE you need to get this fixed ASAP, this is POOR Customer service. It is a trackpad issue and if you touch your trackpad it hangs everytime.

I Have been having this same problem and thanks to reading this thread have set up a mouse for when i use photoshop and thats fixing the issue ( temporary fix I hope. . Adobe? )

How can we buy software in good faith then be left 3 moths later with no concerns from Adobe about these issues. If you can't fix it then send me a code for a free upgrade

adobe seems to be if on this

just say no to adobe

Had the same problem like everyone else, Elements 12 hanging when I upgraded to Yosemite and to be honest I just uninstalled Yosemite and went back to factory settings and Snow Leopard and then re-downloaded  mavericks.  All works perfectly well now.   If I was you just wait a few months  until they sort out this mess and then upgrade to Yosemite.

I have same problem, but I just connected my magic mouse, and then It worked...

There is a workaround to fix it: Photoshop Elements doesn't respond when you use editing tools in Mac OS X 10.10

I just got off chat with Adobe. I'm having so many issues with Photoshop Elements 12 Editor and was going to upgrade. He informed me that an update will be available soon for us using Photoshop Elements on OS Yosemite.

Do you know when the update will be available?
