Is progress bar on startup normal?

During startup after a complete shutdown, a progress bar appears while files are loading. Is this normal for Lion? Did not see it in Leopard. Curious because two things happen during startup: automatic login does not work (minor issue) and monitor resolution defaults to highest resolution rather than resolution set in Preferences.

iMac, Mac OS X (10.7)

Last time I saw that progress bar on my MacBook I discovered that my hard drive had some issue and I had to run disk utility to repair it - and it happen back with Snow Leopard.


So, my guess is that Lion uses the same approach: the progress bar is not a bug, instead it is a clue that you should run Disk Utility, and for that matter you need to boot from other disk than your primary HD (try Command-R when booting and select Disk Utility after the system goes up).


I hope this would help.

I'm having the same issue. I have a brand new iMac that I bought just last week and did the up-to-date program to lion and I have the same progress bar everytime I completly shutdown and start back up. On top of all the problems listed above. iTunes won't load album covers. I always have to restart my computer to get everything working right. Anyone find a solution yet?

I just purchased my iMac a couple of weeks ago and installed Lion. The progress bar has appeared on at least 6 occassions and after finally opening, I llose my Wi-Fi connection and I have to re-boot. It then works perfectly. After each failure I repair my disc permissions. I don't think it is a HD problem, as when the iMac had Snow Leopard (installed on the iMac) this problem never occured. What gives Apple???

Same issue here after upgrading my iMac 2010 from SL to Lion:

- need to login after startup from poweroff (although automatic login is configured)

- bad video performance (choppy refresh when swiping through desktops/full screen apps

- some websites behave not correctly (not loading, wierd stuff, ...)


After restart everything is back to normal.


I already tried to reconfigure automatic login, but no luck.

i have the same issue.

when boot up till login screen with account selection, top menu bar will showing battery status (%), time and wifi status. If i see wifi status icon is hollow triangle, i know that after login my top menu bar gonna missing all icon (sync, time, bluetooth).

after restart the machine and see wifi icon with 4 bars, everything will be fine after login.


now everytime i boot the machine need restart once in order to get working top menu bar.

btw i installed istat & dropbox apps but unlikely caused by them.

hopefully next Lion update will solve this small issue and i really like new Lion interface.

I'm also experiencing this problem:


During startup a progress bar is displayed and I'm taken to a log-in screen. If I continue without a restart the iMac is extremely sluggish and the updated graphics scroll. A restart fixes all these problems however this problem persists no matter whether the drive has been checked and I log out with or without the restore option.


I have updated to 10.7.2 and the problem still persists.
