yosemite compatibility, now or soon?

I don't see any comment on yosemite (Mac OS 10.10) here. Is the latest yEd compatible? If not, when is an update projected?

We haven't tested with Yosemite yet, but it should just work. Simply give it a try!
I suggest you try. Because it doesn't work! Yosemite requires Java 6 which is not installed with Yosemite. Who wants to go installing multiple Javas!
I don't think Yosemite requires Java 6. As far as I can see, Yosemite doesn't even come with Java.
But that shouldn't be a problem anyway -- yEd 3.13 (Mac OS X installer) comes with its own embedded Java 7 JRE, so there is no need to install a system-wide JRE on your Mac just to run yEd.
Ok I tried again. I downloaded 3.13 onto my osx 10.10. When I try to run yed I get the message:

"To open yed.app you need to install the legacy Java SE 6 runtime."

"Simply give it a try!" would be good advice if I were already on Yosemite wondering whether to try yEd. Instead, I'm committed to using yEd, and wondering whether to upgrade my OS. Since updating an OS is not easily undone, I need to know beforehand what to expect. Thanks to all who have warned me away from the cutting edge!

Unfortunately, yEd doesn't work very well on Yosemite, it slows down the whole system.

We finally got a Yosemite test machine giving me the chance to test yEd on Mac OSX 10.10.

For me, installation worked without problems. And I tested installing yEd from the yEd-3.13.dmg disk image with

  • no Java installation at all
  • only Java 7 in /Library/Java/JavaVirtualMachines/ (the default location for Oracle Java)
  • only Java 7 in /System/Library/Java/JavaVirtualMachines/ (the OSX default location for Java)
  • only Java 8 in /System/Library/Java/JavaVirtualMachines/
  • both Java 7 and Java 8 in /Library/Java/JavaVirtualMachines/
  • Java 6 in /System/Library/Java/JavaVirtualMachines/ and Java 7 and 8 in /Library/Java/JavaVirtualMachines/

Not once did I get "To open yed.app you need to install the legacy Java SE 6 runtime." According to Java SE 6 on Yosemite? this is not a yEd problem but general Yosemite/Java issue. Moreover, Eclipse Kepler for OS X Mavericks request Java SE 6 suggests that it is not even specific to Yosemite either. The top answer in the Stack Overflow thread also mentions a possible fix/workaround, by the way.


Regarding yEd slowing down the whole system, that was not the case for me either. However, I did test with a conventional 19" display using a 1280x1024 screen resolution. So, I cannot tell how yEd performs on high-resolution retina displays.
