After upgrading to Lion blue screen appears at start up have to reboot to log in

I have been having issues when I first downloaded and installed Lion it installed then when it rebooted a blue screen would appear and nothing would happen. I rebooted the system and it came up. Now I installed the latest software update and the same thing happend did the same steps. Yesterday I had to boot my computer up twice for it to get to the lion login screen. I have called apple and their resolution is to wipe out and restore from time machine. Has anyone else seen this issue?

Sounds like directory damage of some sort. A few options.
1) Buy Diskwarrior. Probably the premier tool for directory repair. There's a download version but it needs to be run from a booted drive which it seems you don't have. You can wait for delivery of the disc which will allow you to boot from the disc and run the application.
2) Buy an external firewire hard drive. Get one big enough for future backup use. Meanwhile, install a new version of the operating system on that drive, boot from the drive and see if you can even see the files on the main rive. If directory damage isn't too bad you may be able to copy critical ones, though the problem with directory damage is you don't know if you're copying a damaged file. That's when just getting Diskwarrior first may just make more sense.
OSX doesn't let you make a bootable disc just by copying files onto a CD the way OS9 used to. There's a utility called CloneX that does this, but I haven't tried it. Usually what you can do is clone hte internal drive to an external drive as part of backup. The cloning places a bootable copy of the OS onto the external. Simply dragging OS files across no longer works.
By the way, the external drive has to be Firewire in order for it to be boootable. USB is okay for backup but you can't use it to boot an older computer in an emergency (new Macs are okay).

Blue screen appears during start up and freezes

During start up the apple logo appears and locks up. Re booting results in blue screen. After re booting 3 or 4 times finally boots fine.

If you are still not working properly you might want to try the recovery mode http://support.apple.com/kb/HT1808
It is a useful link to keep in mind.

Satellite P100-347: Blue screen appears on start up - unable to boot volume

Recently I left my 2 younger brothers playing NFS Carbon on my satellite P100-347, preinstalled with media centre 2005 edition, and now it fails to startup.
During the startup process eventually a blue screen is displayed for about a second and then it shutsdown (I manged to make out the words "unable to boot volume" from the blue screen).
I tried booting with an XP media centre DVD but it only gives me an option of reinstalling the OS with a price of losing all my very important data. Normally I would have recovered the system but I don't want to lose my data.
Is there anything i can do other than taking it to a technician?

Hi
Well, mostly the BSOD appears due to a hardware problem or serious software issue.
In your case the software problem is possible
Unfortunately, I think the new OS installation is the best way to get the notebook running correctly.
Now you want to know how to save the data and files well, I think you should remove the HDD from notebook and should try to connect the 2.5 HDD via external USB controller to another computer. Then you could save the files on the other HDD
I think, now you know that the regular backups are important and necessary!!!!

Blue screen appears during start up

Hi! My macbook before it bacame a blue screen, shows that the start up disk is almost full but i ignored it...and then suddenly it doesn't start up anymore and shows only blue screen with arrow...pls help! I don't know much about computers! :(

Boot up in Safe Mode.
Startup your Mac in Safe Mode
A Safe Mode boot takes much longer than a normal boot so be patient.
Once you are in Safe Mode, you need to delete data in order to free up disk space, ie., photos, video, etc.
When you are in Safe Mode, control click the MacintoshHD icon on the desktop then click Get Info. You'll see Capacity & Available. You need at least 15% available disk space.
Then click Restart from the Apple () menu.

ICal event have disappeared after upgrading to Lion. Please help!

After upgrading to Lion, pre-existed calendar events (Newer ones) have disappeared. How can I recover?

Greetings Alex,
If you have a backup of your computer from before you upgraded then you can restore the data from your backup: http://support.apple.com/kb/HT1553
--- Let us know if you have a backup and if so, what type it is and we can tell you how to restore your calendars.
--- If you don't have a backup, consider starting one following the article above ASAP. Anyone with information they care about on their computer should have a backup. It is a hard lesson that every computer user learns at least once.
If you do not have a backup from before you upgraded:
1. Make an iCal backup so you don't lose what you have currently: Click on each calendar on the left hand side of iCal one at a time highlighting it's name and then going to File Export > Export and saving the resulting calendar file to a logical location for safekeeping.
2. Go to iCal > Quit iCal
3. Remove the following to the trash and restart your computer:
Home > Library > Caches > com.apple.ical (There may be more than one of these. Remove all files and folders that start with this phrase)
Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache if present)
Home > Library > Preferences > com.apple.ical (There may be more than one of these. Remove all files and folders that start with this phrase.)
---NOTE: Removing these files may remove any shared (CalDAV) calendars you may have access to. You will have to re-add those calendars to iCal > Preferences > Accounts.
---NOTE: To get to "Home > Library" in Lion:
4. Open iCal and see if the events you are looking for magically reappear.
If the events don't appear and you don't have a backup or have the events on another device like an iPhone or iPad then your only other option would be to use data recovery software or a data recovery company to try to get the data back (although it might be easier to just re-create the data as best you can).

You can contact a local Apple Authorized Provider to see if they offer data recovery services: http://www.apple.com/buy/locator/service/
There are many nationwide / worldwide data recovery companies out there. Here are a few examples:

After upgrading to Lion should I have tatty grey screen on opening with boxes for password user?

After upgrading to Lion on Wednesday last I now have a tatty grey screen on booting-up with the two boxes for user name and password.Gone is the old blue screen. Does anyone else have a grey opening screen?
Also this evening on booting the grey screen appeared but I could not immediately type any info into either box.After switching on/off several times I gave up and left the iMAC on with an inactive grey screen.About five minutes later the HP printer went through a re-calibration or cleaning process,of its own accord, and I noticed that the cursor on the screen had moved of its own accord.I then found that I could insert info into the two boxes and here I am with the iMAC open.Anone come across this issue?

Hello again Gary,
After trying your PRAM suggestion, everything was OK however, when I restarted my iMac the next day, the same Grey Screen apppeared whith the request for user name and password?
This has repeated for the last 3 days!
I have tried the Utility to check the HD "Verify Disk Permissions" which shows a long list of "faults"? and I have done this twice now.
Also I have to do the PRAM start-up in order to get online and use other programs. I get frequent messages that say my "Applications" are for the wrong OS?
After using the PRAM keyboard start-up I get a screen with a "Bar" similar to the Windows XP start-up proocess and a grey blob moves along this "Bar" until the iMac starts.
On one site it mentioned that this iMac may need an "Firmware" update/correction; however I can not find any Firmware to download for this machine.
My iMac is a 21.5" Model A1311.
Do I need to do a complete Format of the HDD and re-install Leopard and then try Lion again?
Very frustrated,
Maureen

Try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose any data by resetting, but it can cure some glitches.

There is always a blue screen appears after the Apple logo during the booting process. And then everything is back to normal. What is this thing? Is there something wrong with my screen or something?

TS1541 a blue screen appears after a gray screen with the logo and the spinning gear

start up problem...a blue screen appears after the gray screen and the spinning gear

Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk. You could have some directory corruption. Let us know what errors Disk Repair reports and if DU was able to repair them. This could just be a start in repairs and you may need a better utility to finish the job.
Then Repair Permissions.
No need to report any Permissions errors........we all get them.

What operating system version, and do you have any backups of your data off the machine? TimeMachine? Option Key bootable clones? Storage? DVD's?
A reinstall of the operating system may be in order as a last resort, so if any of these steps on these links get you into the machine, make sure to backup your personal data (Music, Pictures, Documents, Movies) off the machine to a non-encrypted powered external drive regular storage drive (not TimeMachine as it might be corrupted too) and disconnect as soon as possible.
Good Luck and report back all what you tried.
Also report what change occured before this tragedy happened, was there a Software Update? A EFI firmware update? Etc.

Left speaker no sound, no wi-fi, hang up after first or second booting then blue screen appears

hi there! my laptop always hangs up everytime I open it. Sometimes it open up after minutes of waiting then gradually hangs up before blue screen appears. I had to long press the start button again and again before I could use it.
By the way, there are times I had to switch into safe mode and found out that the audio is not working anymore. During normal mode, only the left speaker is operational. Lastly, wi-fi signal will constantly disappear after rebooting.
please help

Hi,
Have not seen any reports of negative experiences (unlike recent Microsoft updates) from the last batch of Windows Updates.
I would guess you have a coincidental hardware problem.
A failed HDD would yield an error at boot. You would still be able to boot to the BIOS if you desired.
Normally failed devices (memory, GPU, CPU) will give audible and visual error codes. Exceptions will always happen.
Could be the battery, power supply, or maybe the motherboard has bit the dust. You will probably receive no visual or audible error messages when the motherboard fails.
Try booting with one monitor.

Use iTunes to do a reset to factory default condition. Always be sure to do your backups before fiddling with your iPad. You might do both the iCloud and the iTunes backup, just to be sure!

keithfrommariettaOct 12, 2014 3:25 PM Re: IPAD2 very slow after IOS 8 upgrade
Re: IPAD2 very slow after IOS 8 upgradein response to pacoKAS
SOLVED: IOS 8 Issues on iPad 2:
I just returned home from a visit to the Genius Bar. Like you and many others, when I upgraded my iPad 2 to IOS 8, it became practically unusable. It was VERY slow, lagged whenever trying to to do anything. Lots of screen freezes and apps spontaneously crashing. I was convinced that the processor on the iPad 2 just couldn't handle the new IOS and I went in to see about restoring to IOS 7.
Thankfully, I was hooked up with a very sharp guy at the bar. The problem is not with the OS, it is with it being an *upgraded* OS. He used the analogy of when you had an older Windows computer and how over time (and over upgrades), they just tended to get slower and slower because of all of the garbage that was carried forward in the upgrades. At those times (and if you've ever had a Windows computer, you get this), the only thing that would speed it up would be to wipe the machine and do a fresh install of the current OS and then reload your apps, and the viola, everything would be fast again. Well, it turns out that IOS can suffer the same problems.
THE FIX: FIRST, be sure you have a current iCloud backup of your device. Connect your iPad to a computer that has a clean fresh copy of IOS 8 on iTunes (this is best done with a computer other than the one that you sync your device to because you DO NOT want to restore it from a back up just yet). Ideally, if you do this at an Apple store you'll be assured of the right version there and someone to answer any questions you might have along the way. You then hold the power and home button down to hard-reset the device and continue to hold them down until it reboots into recovery mode. You then follow the instructions on the computer to reinstall the OS on the device (which wipes everything from it and then reinstalls a clean copy of it). Once this is done (which only takes about 15 minutes), your device will reboot and ask you to set it up. Answer the questions about language, location, etc. and continue until it asks you to log into your iTunes account. Once you do that, it will ask if you want to either 1) Set it up as a new device, 2) Restore from iCloud, or 3) Restore from iTunes. Choose (2), restore from iCloud. This will ensure that it brings down "clean" copies of all of your apps and preferences rather than the potentially corrupted ones that might reside in your iTunes backup. That's it! It will take a few hours depending on how much data and apps you have, but I am happy to report that my iPad 2 is now running IOS 8 and it's running as fast as it ever did when it was brand new!
To sum it up, this process 1) Wipes your device and the garbage causing your problems, 2) Loads a clean and bug-free version of IOS 8 to your device, and 3) restores your apps and data so that it looks just like it did before the wipe, with the exception that it works now! :-)
Note also that by following this process you don't have to go through the painful and laborious process of reloading all of your apps, data and/or settings. iCloud takes care of all of that for you.

Back to my mac no longer works after upgrading to Lion

Back to my Mac no longer works after upgrading to Lion
After I upgraded my home machines to Lion, I can no longer access them from my work computer, which is running Snow Leopard. When they were both Snow leopard, it worked fine. How can I get them working again? I don't have control over the OS on my work computer. Is it necessary for me to downgrade all of my home computers to Snow leopard in order to get them talking again?
Additionally the binoculars icon appears in the menu bar all of the time. In previous versions, this would only happen when somebody connected to my machine. Could these problems be related?

OK, so further investigation has addressed the BTMM issue on a remote machine.
With all machines running lion, I was having issues trying to log in to a standard user headless machine already running. In Snow Leopard, I had no issues with this since you can log in via screen sharing using an admin login that's running a standard login. Lion allows multiple accounts to be signed in which is handy since you can now run virtual sessions. This means you can admin the remote computer without bothering the remote user.
The problem was that now logging in using admin login brings up the admin account (which makes sense) instead of the desktop to the standard login. I applied a similar solution to a problem that was related to screen sharing I found on this board. What I believe to be the fix is to add the standard user to the screen sharing user list. Then screen share to the remote account using the standard user credentials.
So on the remote computer, in System Settings->Sharing->Screen Sharing, add the standard user to be allowed access. Previously I only had admins. This may not be an ideal solution for what I'm trying to do since the remote computers primary login is the standard user to be used as a common computer, but it now works so I am happy with it.
Now my only "problem" is my AEBS complaining about my MobileMe credentials, but it doesn't appear to have an impact on BTMM performance so I'll quietly wait for a fix down the road.
