I have just downloaded the OS X 10.10 – Yosemite Beta 4, and at first sight most of my reported issues seems to be gone by now. Still a bit questionable is the information provided with the update. Once again – 850 MB update with the information “recommended for all users” is a bit too less information, but maybe the majority feels happy with it.
So from my previous post  the issue with the empty help menu is gone – there is now help where you need it. The search function in my Calendar and in Mail is still not working – whatever I enter, I do not get any search results back. The issue with Mail, where I was not able to write any text was fixed by an previous update already.
From the first test report  I think most of the bugs are fixed. Quite annoying for me is the thing with VmWare, as through the upgrade I am kind of forced to buy a new licence for VmWare 7.
Testing other applications I recently found a reproducible bug in iBooks Author . Trying to add some additional text to the classical layout with the made-up text, the iAuthor application crashes as you can see.
There has been done a lot recently and many things improved, but still there is some way to go for the final release of Mac OS X 10.10. Beyond the open bugs there are also some features I would like to see. For example since upgrading my iPhone to iOS 8, I still do not see the level of integration I expected to see – but that might come up in the next releases.
