Mac OS X v10.7 Lion always boot into safe boot after upgrade?

I have recently upgraded my OS from snow leopard to lion and the upgrade process was smooth and no problems encountered.

I am also running boot camp with windows XP installed in the same iMac.

After the upgrade, my iMac almost always boot into safe mode whenever I switch it on and I need to restart it again and it will then return to its normal mode.

I wonder anyone encounter the same problem and if so, please give me a hand to solve it.

Thank you very much!

iMac, iPhone, Power Book G4 & MacBook Pro, Mac OS X (10.6.1)

I believe I have found a permanent solution. It worked for me, so try this and let us all know if it works for you.

I reset the PRAM... here's what you need to do:

1. Turn off the Mac.

2. Unplug everything, including the power.

3. Hold down the power button for 10 seconds.

4. Plug only the power back in.

5. Turn on the Mac.

6. Hold down Option+Command+P+R.

7. Keep holding until you hear a second chime. Then let go.


From then on, it should start normally. Hope this works for y'all.

Same problem here with my 2011 21" iMac that I purchased in mid July.


I have a wireless keyboard, trackpad and mouse. When I power everything off and turn off the power strip then later turn on the computer it boots into Safe Mode.


Also, the Wi-Fi (formerly Airport) icon in the menubar is just the empty outline and clicking on it gives me the message "Wi-Fi: No hardware installed". Rebooting fixes this.


I spent an hour on the phone with an Applecare manager who had me run Disk Utility repair after booting into the recovery partition. Disk Utility found some disk errors, which I thought was strange for a new computer, and repaired them.


The problem still exists though.

I think i got it :


The progressbar while booting ( booting in safe-mode ) came from the wireless keybord and is reproduceable.

At evening I shut down my iMac an put off my mouse and keyboard. To startup I put on the iMac and immediatly after I switch on keyboard and mouse. In tihs case the keyboards sends some event wich leads to safe-mode.


Know I wait until I switch on the keyboard. In my opinion this is a bug, i can live this way but i hope it will be fixed.


I will know take a look at it while not switching off the keybord, power consumption should be acceptable
