Whenever my rMBP wakes up from sleep, it shows a log in page with my user name. The page has a metallic gray background. After I enter my password, another page opens up with my wallpaper along with my user name again, and I have to enter the password one more time.
Output of diskutil list
for /dev/disk0 is:
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *500.3 GB disk0
1: EFI 209.7 MB disk0s1
2: Apple_HFS Macintosh HD 499.4 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3
How do I disable multiple login windows each asking for a password when my laptop starts or wakes up from sleep?
