OS X V10.7 Lion :: Mac Will Not Restart But Will Boot
May 15, 2012
The machine will not restart. When I attempt a "restart," everything seems to shut down properly. When trying to start back up, the machine hangs at the gray screen. I have left it there for a long time and nothing happens. However, I then force a shut-down by holding the power button for a few seconds. After that, the machine will start up properly. Again, a "cold" start works perfectly fine. Only a "restart" causes a problem and will always hang at the gray screen (no logo - nothing). This is the only way I can restart my machine.

I can't get Lion to boot. Here's what I've done/tried. Where applicable I have repeated these steps just to be sure my results were consistent: 1) When I boot, I can't get past the grey screen with the apple icon and the spinning spokes. 2) After reading reviews on CNET, I installed Avanti!3) Avanti would not finish scanning and would not operate on the sketchy files it found (most just highly compressed files).4) In Finder I used Quit, then Force Quit on Avanti, only to have it start again as soon as it closed. Meanwhile it kept opening & then crashing 2 other apps: extEdit and Mail (neither of which I was using).5) I tried to shut down, but Avanti stopped the process.6) I tried trashing Avanti, but it I just got the 'moving to trash' swirly status bars running indefinitely.7) I tried deleting sub files of Avanti hoping it would cripple it sufficiently that it would not return when stopped.8) I did a hard reboot and opened to the same problem.9) I loaded MacKeeper, but that too crashed almost immediately each time.10) I tried opening System Preferences, but it too crashed immediately each time. Here's where I screwed up:11) I examined Avanti and thought I'd stop the parent process and reboot.12) I stopped the user version of launchd (Quit, not delete)13) My screen instantly went grey - no other features.14) I did a cold reboot, and got no further than the grey screen described in #115) I tried a safe boot. Same result.16) I tried emptying the PRAM. Same result. So, I'm totally stuck. I've been all over the internet looking for the answers, but it all seems to be about what launchd does, not what to do when it doesn't (at least I assume that's what's happeniing.) This being a MAC, I don't have a boot disk for repairs. In addition, none of the built-in repairs/work-arounds work because, of course, I can't get in. So, if you think the only thing to do is reload the OS, do I have to grab all my data first? I do have access through my laptop via sharing.

my MBP gray screened with the "You need to restart your computer..." error message. I have absolutely no idea what could have caused this, although Final Cut Studio 2 did finish installing about 10 minutes before it happened for the first time. I tried restarting a few times but the error message kept on appearing about 30-60 seconds after the desktop loads up. I left the laptop alone over night and in the morning, I switched it on and it appeared to have fixed itself but this afternoon, the restart screen came up again.
I have a time machine backup from yesterday, but as I have work due in at the end of this week, I'm a little bit panicky at the moment.
What I'm concerned about, is that if I reinstall Snow Leopard, then restore from a Time Machine back up, it's just going to restore this error.
If anyone could help, it would really be appreciated. (I've attached the error message if anyone doesn't know what I'm on about.)

My iMac will not start up when shut down, or awake from sleep.To get it to start i must turn off the power, and turn it back on, then it starts up and runs fine.If i Restart it, it switches off, and will not power back on. The machine still works great but is begining to be a pain in the back-side cycling the power every morning.I have done an SMC Reset, and that did not change it.
I have also added a new user, and when i logged in as the new user, it did restart a couple of times (cannot remember the exact amount) and then when i switched back to my normal account it restarted fine... i assumed it was fixed... but after that it's gone back to it's old painful self..

G4 won't fully boot, we turned it off for the day, came in the next morning hit the power button and waited while it booted. It got held up at internet services, we unplugged it from the network restarted. It would boot all the way up so you could see the desktop wallpaper but then the black "you need to restart" screen would pop up.

I verified the hard disc on my mid 2010 3.06 ghz 10.7.3 iMac this morning to be greeted by a box telling me this disc was corrupt and that I needed to restart while holding cmd+r until the apple logo appears then to repair the disc.at this point I would like to say that I am posting this from said iMac and it boots up normally and runs fine.but,when I start it holding cmd and 'r' let go at the apple logo the cog starts turning below the apple for about 10/15 seconds then the apple is replaced with a circle with a line through it (the cog keeps on spinning below it) it seems like it would just sit like this for ever - after about 5 mins I held the power button, turned it off, turned it back on again and just left it to boot up normally - no problems. thought I would try it again - turned it off, held cmd and r exactly the same as before......

Spotlight still wanting to reindex their mac after every restart/reboot - the finder becomes completely bogged down until spotlight finishes reindexing my mid 2011 iMac hard drive. I have tried a clean install from scratch, clearing the caches, deleting the spotlight files and letting it reindex from scratch, nothing seems to get rid of the initial lag once the desktop first appears - it happens after every restart or initial boot up….as soon as the icons for the hard drive appears, it immediately goes into "reindexing iMac hard drive" and takes a few minutes to complete, during that time, the computer is totally unresponsive to anything until it finishes. (Computer configuration = Mid 2011 iMac with 16GB ram and 500GB H.D. that has over 200GB of free space - Time machine backs up to a 2TB Lacie D2 Drive via firewire 800).

I have an issue with my 13" Macbook pro mid 2010 OSX 10.9.3. It won't boot after restart, but boots normaly after shutdown and start again.
Few months ago my primary sdd Corsair hard disk (I have 2 hdds. Replaced the original with the CD-rom) which I installed 2 years ago, stopped working. Gave the macbook to authorised service provider in my country and they said I need a new hdd and a new hard drive cable. The ssd was still under warranty, so Corsair replaced it with a new one. They gave me SATA3 instead of SATA2 (which at first I didn't noticed). Later they said they don't have SATA2 anymore. Also replaced the broken cabel.
Now it's working. If you start it after normal shutdown, it boots normally. But if you restart it it won't boot at all. The apple keep spinning and the forbidden sign appears. I tried PRAM and SMC reset. Nothing
What should I do? Can the use of SATA3 instead of SATA2 hdd lead to some issues with my macbook? I can try to find and buy new SATA2 sdd hdd but they are expensive and I'm not sure it will fix the restarting issue.

I get a message saying "You must restart your computer." (hold down the power key, blah blah).
I've researched a little bit, and apparently its indicative of a kernel panic.
It's not booting from CD either.... what's going on?

I am running Mavericks 10.9.3.
I always quit out of all apps before doing a shutdown. I make sure that nothing, except Finder, is running when i shutdown. And, I do a full shutdown, not just sleep.
Yet, occasionally, the apps that were running before I quit out of them will restart when I turn the MacBook back on.

I am trying to create a partition with Boot Camp and install Windows XP SP2. Whenever i try to create a partition, the kernel crashes and i need to restart my whole computer, boot up from the OSX CD and then "Repair Disk" to get the lost hard drive space back. I had partitioned my HD last week, but then removed it, but now when i try it, it always freezes the computer. is there any way to solve this problem without my data being lost?

Mac G5 ppc OSX10.4.11
Starting up from any boot disk will give me a kernel panic forcing me to hard restart.
Background:
After many freezes I ran disk utility and I get:
Checking Catalog file.
Invalid index key
The volume Macintosh HD needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
So I use my wife's Imac startup disk to boot it in order to repair but I get the dreadfull death screen (I know how to press the C) I'm thinking maybe it's because her disk if for her Intel proc so I go and buy a copy of disk warrior 4, and same problem.

On Windows I noticed there was an icon in the bottom right (next to the clock) that I could right click and then restart in Mac OS X. Is there a similar thing for OS X that I can just click in the menu bar and restart in Windows?

Last week I finally upgraded from 10.6 to 10.7, but now my Mac Pro (2008) won't boot properly. It'll start to boot with the gray screen and the Apple logo, but then the entire screen goes gray and it just locks up there. However, if I reboot and hold down the Option key to bring up the list of bootable drives that works fine. I've checked my Startup Drive settings and the proper drive is selected. why it won't boot on it's own anymore? Holding down the Option key is getting old.

I restarted my computer, and when it booted back up the clock was reset to Dec 31 2000. I did not change the clock, and my control settings are password locked.
Should I be concerned about this, and has this happened to anybody else?

it varies but generally every 5-15 min I need to shut off my wi-fi and turn it back on to connect to the network. I have a netgear router and just updated the firmware today hoping that would help but it did nothing, helped the windows laptop but not the iMac. It is set up in WPA-PSK [TKIP] + WPA2-PSK [AES], does mac not work well with that, will WEP work better? If I change to WEP will it mess up a laptop running Windows 7 Pro?

I am on my MacBook pro from 2010, reinstalling Snow Leopard and Lion afterwards. I install the updates and some programs (Plex, uTorrent, Chrome) only to realize that when I restart, some preferences completely ignored.. All programs added to the Dock are gone again, the assigned log-in items don't start up, iCloud was logged out again, mail settings were reset.I reinstalled the whole thing, except for Lion, and it all worked fine. So anyway, I thought it was the laptop. Some sort of hardware problem or something, right? So I just got this new Mac mini, with Lion, and it does the same exact thing.It doesn't remember some changes I made. I tried to repair permissions, but it doesn't do anything.
