I have constant crashes/freezes when waking up on Yosemite, and something about having iCloud disabled makes every iLife application show unrelated dialogs (usually "This will overwrite the existing file on iCloud" warnings, despite the file not existing at all, nor having iCloud), the EULA box randomly shows up in System Preferences and gets stuck in an infinite loop of showing me the terms even when I press cancel, yada yada. I agree with the word "shoddy". I can work around all this, but it's like nobody bothered to test it. I'm part of the Appleseed program and send in every bug I find, but apparently they're all minor enough to not be patched. Frustrating.
