Hi, I have Yosemite 10.10.2 running on the latest Parallels 10.1.4 (28883). The update to Yosemite 10.10.3 should be done through the App Store. You should be enrolled to Apple's Beta Program of course. I have downloaded the YosemiteBetaAccessUtility.dmg, installed it (just like the native Yosemite on my Mac) and now I only get Thunderbolt Firmware Updates to 1.2 every time I open the App Store but just 10.10.3 isn't available. Any idea? -Alex Apple Beta Program: https://appleseed.apple.com/sp/betaprogram/
Hi Alex, For now Yosemite 10.10.2 is the only version fully compatible with Parallels Desktop 10. As Yosemite 10.10.3 is in beta, we cannot guarantee it will work as expected yet, as always with beta versions. You can subscribe to our newsletters as suggested at http://kb.parallels.com/en/117011 to get latest updates on Parallels Desktop. Let us know if you have any questions.
