Hi there, My new 21.5" 2013 iMac with full configuration is great, but it does have one weird thing. When rebooting or on startup, the progress bar jumps from the center of the screen to the left bottom corner at around half the startup progress. It's still amazingly fast, but I just wondered if anyone else experiences this "issue". Also the screen is mirrored on my second screen at the startup and login screen, but becomes a "normal" extended desktop when logged in. Thanks!
