i just installed Mac OS X 10.8 Mountain Lion and downloaded PlayOnMac v4.1.3. My Mac says (when i try to start it) that the app is broken...

Is 10.8 already supported?
Does anyone else have this problem?

Best regards

PlayOnMac works perfectly on my mountain lion.

Maybe you could try to redownload it

Just downloaded and tried for the third time... nothing changed.... :( ... Uninstaller works (Gatekeeper just asks me if i trust it and if i say yes it runs as expected)

Just changed my Gatekeeper settings to allow everything, then i started PlayOnMac - et voila - it starts. I'm now changing back my Gatekeeper settings. Thanks for your help!

I have installed Mountain Lion, updated Xquartz and installed the latest version of PlayonMac.
I want to install Scottrade Elite, and going through the "install non listed program" process.
As soon as the virtual drive creation step starts, a window pops up asking me to install X11. X11 is no longer part of Mountain Lion which is now fully integrated with XQuartz.
So basically i am stuck at this point... nothing gets installed.
Any help would be greatly appreciated.

Thank you.

Try to restart your computer

Thank you for your reply.
I followed your suggestion and restarted the computer but i had the same issues.
I then proceeded to fully shutdown, wait 5 minutes, then turn it back on but with the same results.
I am at a loss.
Just for your info, i am trying this on the new MacbookPro with Retina display.
I took a screenshot for you, is there a place where i can post it so you can see it?

When i try to install the software through PlayOnMac a window pops up saying:

To open "wineboot" you need to install X11.
Would you like to install X11 now?

If i say CONTINUE, it takes me to this apple.com page:


Which tells me that X11 is not included in Mountain Lion and that XQuartz is now the standard (note: I have XQuarz 2.7.2 properly installed on my system).

Hope this helps you in figuring out why this is happening.

Thank you for the support!

XQuartz does not seem to be well installed.

Try to run it manually

I was in a similar situation, but found only this topic without a solution. What solved the problem for me was running this on a prompt:
$ sudo /usr/X11/libexec/xquartz_postinst.sh

but I don't recommend it, unless you look at that file, understand what it's doing and that it'll solve things for you.

In general, I'd recommend reinstalling XQuartz, I believe that should work as well.

Before that, both the stub X11 and XQuartz were installed.

I assume the situation arose (for me) because I made a fresh install of Mountain Lion, followed by a Time Machine restore of my old system (including XQuartz). Probably the restore avoided overwriting system files.
