Q: Yosemite Cannot Login After Sleep
I have a 2012 Macbook Pro and upgraded to Yosemite today. I also have an external HDMI monitor connected with the Thunderbolt to HDMI cable.
The problem is I cannot login to the machine after waking up from sleeping (the machine not me ). The mouse freely moves around the blank external monitor, but the Macbook's native display seems to be frozen as judged by no movement of the mouse, no response to key presses, and no action taken when closing the lid. Also no response when unplugging the monitor cable.
The only way to resume work is to hold the power key and force a reboot.
This happened twice already today and is quite annoying. The last time I saw this issue was with Mountain Lion, but Mavericks seemed to have fixed this. On a related note, after rebooting, my audio is muted unless I remove and reinsert the 3.5mm plug to the external speakers. So now with Yosemite, one step forward, two steps back. This is the best type of issue to shake customer confidence in ability to resolve issues and manage software releases. Yes you are correctly detecting some of my emotions coming out here because I feel like I am part of an extended beta test.
I saw another user had a similar problem in a different thread, but he is using SSD. I posted this because I am using completely stock Apple hardware inside the Macbook pro.
MacBook Pro, OS X Yosemite (10.10)
