Harmony 10 running on Mac OS Mavericks/Yosemite?

Has there been any issues with running Harmony 10 in Mac OS Mavericks 10.9.5 or Yosemite?

I am currently running Mavericks 10.9.5 and have not installed Harmony10 yet. I was thinking of upgrading to Yosemite.

Can anyone out there give me some good advice? Will it work better in Yosemite?

The current downloads for all Toon Boom software are compatible with Yosemite. Problems with Yosemite had been reported prior to the announcement from Toon Boom. I believe 10 will still present potential issues.
