How Stable Is DR 12.5 in MacOS?

For those that have been using DR12.5 for a while, how stable is it under MacOS?
I'm still in 10.10.4 for the stability it offers.

In a couple days I'm finish a project and I won't upgrade until it's done. However, I would like give it a try
for my next project which is going to start late next week.

Thanks in advance.

Its been out for 24 hours. Installed 20 hours ago. No crashes so far. More time needed to answer fully.
My system...

Mid 2010 Mac Pro 5.1
OSX 10.10.5
2 x 3.3GHz 6 core Intel
48 GB ram
GTX Titan X 12GB graphics card
USB3 card
OWC SSD 500Mb boot disk
4 x 6TB in raid 5 yielding 18TB

Very quick!

Do a backup of your database first.
Then upgrade and test stability. If it's not good on your machine, you can downgrade and use the old database from your backup anytime.

There should be no problem with Yosemite 10.10.5 anyway, independently of the beta.

That OS will stay on my machine as long as possible…

Thanks to all for your kind responses and suggestions.

It's crashing every time at autosave. After system restart it works well for a while then crashing again. Very annoying (MacPro Late 2013, ElCapitan 10.11.4)

Autosave is working fine for me el capitan, macbook pro retina 2014.
