Lion won't start!

Please help - I tried save mode but didn't work..

You need to be more descriptive with your post. At this point we know very little to nothing.

Lion won't start stuck in loop?

Lion won't start, stuck in loop

This morning my Dual-Core Intel Xeon, Mac begins start up, then turns completely off. My (own) memory is faulty, but I think I've upgraded to 10.7.5.
At first it was stuck in start up so I turned it off then on again.
My first warning was when I came into the office this morning and the APC was beeping. Why? That's a mystery too, because its battery appears to be fine, and turning it off then on again the "green" operating light shines as normal. Funny though, when I turned the APC off then on, the computer tried to start up, but I'd shut it down the night before, ...unless, and here's again a memory glitch, ...I may have let it "sleep" overnight, though that would be highly unusual for me.
Hints?

PS CS5 under Lion--won't start?

Just installed PSCS5 Ver 12.0 x64 under Mac OS X Ver 10.7.2.
Photoshop won't start, but hangs at "Reading brushes..."
Have tried opening it from Bridge and opening directly from the Dock (without Bridge).
Any suggestions or pointers?

Have you performed the usual trouble-shooting routines (trashing prefs by keeping command-alt-shift pressed while starting Photoshop, 3rd party plug-ins deactivation, system maintenance, font validation, etc.)?

Mac OS 10.7 (Lion) won't start After Effects CS5.5 because it's a powerpc app!?

I've had CS 5.5 Master Collection installed on my Mac since it came out. All the CS 5/5.5 apps I've used up to now have worked fine, in 64-bit mode (Photoshop, Illustrator, Acrobat Pro, InDesign). Now I need to use After Effects, but I can't get it to start.
First it said it couldn't rename a Workspaces.xml file in the preferences directory in my home folder. In fact, there was no such file there at all. Nothing to rename. So, I uninstalled After Effects using its uninstaller; then reinstalled it from the install DVDs.
Now, it fails on startup saying the After Effects CS5.5 application cannot be run because PowerPC apps are no longer supported. True: OS X no longer runs apps that require Rosetta. CS 5.5 is does not require Rosetta; it's compatible with Lion. The OS 10.7 Known Issues KB article says nothing about After Effects: http://kb2.adobe.com/cps/905/cpsid_90508.html?promoid=JBQYY
So...what's going on? I need this thing working for a project with a deadline! I don't get it. Anybody seen this before? (I didn't find anything in the discussions about it, nor Google...)

Interesting article, but I knew I was leaving PowerPC apps behind when I moved to OS 10.7, and Adobe claims that After Effects CS 5.5 is fully compatible with Lion. But you must be right about prefs; there's gotta be something causing the Mac OS to think this version of CS is ancient...
Since my initial message, I've tried and failed to find any details about how to select the right prefs to delete. I also ran Disk Utility to repair permissions on my system drive. That got rid of the PowerPC error:) Now on startup AE says mediacore fails to initialize. I can choose to quit or continue on that error, but continuing just results in another error that says dynamiclinkmanager unexpectedly quit, and then AE locks up and I have to force quit it. Not much progress!
No other answers on this so far... Before I uninstall the entire Creative Suite and then delete all Adobe system and hidden files everywhere, any more suggestions? Or a list of the right prefs I should trash?

Mountain Lion won't start with 32-bit kernal

I'm trying to update my Sony NEX-5 to version 5, and every time I click the installer, it says that it runs on a 32-bit kernal.
I tried starting up in 32 bit by holding the 3 and 2 keys, but this doesn't seem to do anything. I remember when I was on Snow Leopard, I could update my NEX-5 without any 32-bit startup necessary. Looking at some forums, even when people were on Snow Leopard they needed to startup in 32-bit...but I didn't.
Why doesn't it start up in 32-bit mode?
Why doesn't the application work on 64-bit? (Chrome is 32-bit...that still works on 64-bit)
Why has Sony even done this to us?
Running Mountain Lion 10.8.2 on the 2012 21.5" iMac.

Yes, the 64-bit kernel is not supported for downloading the firmware update. You may use your neighbors or friends computer to download the firmware. You can also send the Camera to our service center for getting the firmware installed:
Haha! Very funny Sony!
Well, I have a Canon 650D now anyway, and the update isn't a big deal. Just would be nice to update it.

Mid-2010 iMac running Lion Won't Start Up?

I have a mid-2010 iMac running OS X Lion. It was running slow one day so I restarted it. When I restarted it, the iMac went to the white apple logo screen and had a small loading bar at the bottom. After it loaded it would not start up. I have the Snow leapord install disk but I have a wireless keyboard, so I cannot press C to get to the reinstall menu. Any ideas that could help?

Probably your hard disk is damaged. Apple has called some iMacs bought between October 2009 and June 2011 for repair because they have damaged hard disks, so see if you've one of those Macs > http://www.apple.com/support/imac-harddrive
Press C key after the startup sound to boot from the disc, go to Utilities > Disk Utility and repair the disk

Flash CS6 Trial (Mac Lion) won't start up...

When I launch the program, the splash screen loads up to the point of "Loading Accelerators" and becomes unresponsive. I have to Force Quit the application and never get to use the software.
What can I do to identify and solve the issue?

I have the same issue (only intermittent) but I have a licensed install, no error on install. This started on my Mac OS 10.7.4 after recent update to Flash CS6. No problem on my PC. With tenacity I do sometimes get it to launch (takes over 60 seconds). No clue yet as to the issue.

Lion won't start after FileVault initial reboot

Im on a 17" MacBook pro (not i7) with the latest version of lion. I decided to try FileVault, turned it on and set it up as per the on screen instructions. It then asked to rebook which I did. It came to the login screen again after reboot and I put in my password and it wen to a whitish screen with a small grey "no entry" symbol and a spinning wheel below that. Stayed like that for half an hour so I force restarted as I understood it was meant to encrypt in the background) and it did the same thing. Any ideas anyone?

It seems that my partition table is corrupted. The question now is. How to fix it?

Lion won't start after EFI update

I installed the new EFI update for my MBA Mid 2011 (the software updater said it is recomended). The update went fine and restarted the mac afterwards.
Then while booting the apple logo turns to a grey forbidden sign and nothing happens from there. I turned the mac off and tried again. Same thing.
Then I booted the recovery partition and tried to repair my disk. It says that it can't repair the disk because it is corrupted.
Please don't tell me I have to erase the disk. There is some unbackuped data on it and I can't get it out using a linux-live because my disk is encrypted.

Macbook Pro won't start after Mountain Lion download.

Downloaded Mountain Lion for my 2007-08 Macbook Pro. Internet was painfully slow (60kb/sec, usually 15 mgb/sec). After not using it a week while vacationing, I started it up, and it was working fine until it randomly shut down and brought up an error screen (hence the reason it shut down) and asked if I wanted to boot normally. I powered it down; now it won't start at all. Power button doesn't work, demounting the battery for a minute and remounting doesn't work, nothing works. I have a genius bar appointment soon, but am wondering if anyone has some advice.

Close problem - I believe the problem is RAM is storing your last data, and not releasing it, so you cannot boot it. Trying removing RAM fully, then starting.

Screen saver won't start since Lion upgrade. Two different machines, same issue.

Screen saver won't start since Lion upgrade. Two different machines, same issue. Help

For anyone following this thread, I've found a solution to my problem. Turns out that a cute widget called FishTank appears to be the culprit. With it running in Dashboard (even when I don't see Dashboard) the Screensaver and Sleep functions don't work. I turned it off, not because I'm clever, just because I tired of it, and voilà, Screensaver and Sleep are now working. It can stay in my widgets list without any problem, it just can't be turned on. I'm going to delete it anyway, however.
Hope this points the way to solutions for some of the rest of you!
Cheers!

My Macbook pro often won't start up since I installed Lion, and I have to shut it down using power button. My desktop icons don't appear and the dock won't open. I only have the little circle of color spinning endlessly. What's wrong now!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Mountain Lion update, and now computer won't start up?

Writing this for a friend, as his computer is inop at the moment. Hence this message.
He has a new 27" iMac. He upgraded to Mountain Lion a few weeks ago, and then had intermittent problems with apps unexpectantly shutting down.
Now he did a ML update this morning, and his computer won't start up. It gets to the point of the Apple logo coming up, a progress bar, and then the spinning wheel, but then shuts itself down right afterwards.
A safe boot yields the exact same result.
Any thoughts out there on what he could try to get it up and running again?
Thanks much for any and all help.

Thank you for the fast response.
He was able to get into Disk Utility with the Command and R keys, but when he tried verifying the disk, in red it said 'Invalid Node Structure, volume could not be verified completely'.
He went ahead and verified it anyway, then proceeded to repair it. Howver, it stopped repairing, said it cannot repair, and that he should back up files and reformat the disk.
How can he back up his files? He cannot see a way to do it. Is there anything else he can do besides having to reformat the disk?
This is his first Mac (after much prompting from me to go Mac), and he's afraid he's now lost everything on there.

I installed Final Cut Express in new I-Mac OSX Lion 10.7.2 and it won´t start

I just installed Final Cut Express 4 on a new IMac with OS X 10.7.1 and can´t get it sto launch.

It's an accomplishment that you were even able to install it on Lion (normally it won't even install on Lion).
But as you have already found out, it won't start, and even if it does it is not likely to run properly. Apple discontinued FCE and do not support it on Lion. You should get Final Cut Pro X instead.

Lion won't start!
