In MacOS Sierra the lock screen creates this blurred white border (frame) around the background image. Is there any way I can turn that off? For the first time in my life I hate to looks at my mac at this point in time.
MacBook Pro with Retina display, OS X Yosemite (10.10), 16GB RAM, 512 GB SSD
I had this happen to me after updating to 10.12.3. At the same time, Safari got a little wonky on me as well. I just reinstalled macOS (reboot, press cmd-r at the startup sound, then click 'reinstall macOS'), and it removed the white border on the lock screen and Safari seems to have cleaned up also.
I don't know what the white border is supposed to mean (if anything), but reinstalling the OS removed it. Thankfully.
Same problem on my MacBook Pro, cloudy white edges. This is after almost a month after updating to 10.12.3.
I tried to wake the the MacBook from sleep and it wouldn't come back up after trying for 10 minutes. So I did a hard shutdown and then booted up. I got the cloudy white edges on my screen after it booted. Couldn't fix/track down the problem. Ended up restoring from the latest time machine backup before the problem happened. So far it hasn't reoccured.
I had exactly the same issue. Blurred white border after update to 10.12.5. NVRAM update fixed that for me as well. Maybe it's an indicator by Apple that NVRAM should be reset... might be more helpful if they could just pop up a dialog!
I can only tell you that that's not normal, nothing changed in the lock screen in Sierra.
But unfortunately I can't help, I hope someone else can!
See these bugs here:
Sierra has changed some frameworks and how graphics switching works, and that this app and gfxCardStatus, and very likely other ones too, will now trigger the dGPU whereas in the past they didn't).
They are speaking about 2010 model there. Nope. I have a early 2015 macbook pro here has a same ugly lock screen. Dream have it looks bad cause after a couples of days first in my life I looks first in the morning to try to find an answers from the forums !
I have the same thing on the first generation MacBook.
But, I only get the white border after I close the lid. If I start the screensaver, the unlock screen does not have it.
I had the same problem after updating to 10.12.3. An NVRAM reset (restart the mac and hold Cmd+alt+P+R) sorted the problem for me.
I had the same problem after updating to 10.12.5, NVRAM reset also solved it. Thanks!
