After installing Yosemite my Imac just goes to a white screen and freezes, it has been there for almost 36 hours any ideas as to why it is taking so long?
I have downloaded Yosemite from the App store and I attempted to upgrade from OS X 10.9.5. It is stuck on a white screen with a moveable mouse pointer but that is it. I can't get Command + L to work, so I can see any progress that is being made and I have tried to force boot it twice. Each time I force boot the machine I get a progress bar that goes about half way across and then just a blank white screen. I have read on some blogs that patience is the best procedure for this freeze but I have been waiting for almost 36 hours now and nothing is happening. One thing I want to mention is I have VMWare installed with a virtual machine of 300gigs, could this be the cause of the hangup? My 27inch IMAC is about 3 or 4 years old with a terabyte hard drive and 32gigs of ram. I have unplugged everything from the back except the network cable. Is about 36 hours reasonable for an upgrade? Is there a way to cut my losses and revert back to OS X 10.9.5?
When you start your notebook press F8 to enter Advanced boot options.
Is Repair my computer option available?
If yes choose it and press ENTER. Follow the menu on the screen and when you will see System recovery options try to use System Restore option.
Do you have some important data saved on your notebook?
If not install OS again using HDD recovery option and after 2 hours you will have clean preinstalled OS and everything will be OK again.

My Imac just goes to a white screen

Hello, let it cool for an hour or so.
Have you blown the dust out lately?
Get Temperature Monitor to see if it's heat related...
http://www.macupdate.com/info.php/id/12381/temperature-monitor
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed. Or an errant process eating up RAM.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

When accessing Hotmail account on Apple Air ,any page when fully loaded just goes to a white screen, so no actions can be completed. Account is fine on Imac just Air functionality faulty, any advice
thanks Bryce from OZa flashing folder with a question mark popped up,
Can mean that your Mac can't find a system folder to boot from.
Try restarting while holding down the Option key. That should prompt the Startup Manager window where you can select the startup disk and restart.
Startup Manager: How to select a startup volume
If the disk is not available, then it's failing or has failed.
If you did not backup your important files, an alternative would be data recovery but it's expensive.

Both my iPad and iPhone have ios8
On either device in Calendars> edit >shared with> add person when I enter an email address and press add nothing happens - just goes back to edit screen and what I have entered has gone. No error message or any clue about why I cant share my calendar. Please help.UDPATE:
Spoke with Express lane, and issue was escalated. Kudos to the support guys that handled this one (Brian and Yi). Went through everything in detail and took all the crash dumps off the iphones and ipads to send to engineering.
After backing up the contacts, the recommendation was to delete all contacts in iCloud. Doing that caused my iCloud to crash (in the browser), so more crash dumps were sent to apple.
Eventually got all contacts deleted, then did a resync. Looks like IOS devices are coming back to life and syncing again.
Also, Outlook iCloud connector has just been updated to ver 1.0.1 so i installed that on their recommendation.
BOTTOM LINE workaround:
1. Backup contacts
2. Delete contacts in iCloud
3. Delete accounts on IOS devices
4. Recreate accounts on IOS devices.
Hoping a real root cause can be found and real fix implemented. This has caused me to doubt the stability of iCloud, so i will procees with caution. -
10.6.8 update won't install gets half way through then just freezes spinning beach ball for 4 hours any ideas y. Tried and restarted 3 times already does the same thing each time have to hold down the power button to restart. Anyone can help
Ok will check, as of right now I have 82.57gb free, that's plenty of space will check the disk though using disk utility. Also I am now downloading the update from the apple website instead of going through software update

Last night I did an update and now when I turn on my macbook it just goes to the white screen with the apple and stays like that. How do I fix this issue?
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start 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 the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. -

My ipod only goes to the apple screen and freezes then turns off after about a minute. Is this fixable?
Try a system reset. It's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc. -

I used to install the rEFIt to boot with win7. When I deleted win7, I didn't uninstall rEFIt. Nothing wrong with it. One day after I watched movie in full screen,I pressed esc to quit. Then I found the touchpad didn't work. I can't turn off air. I just pressed power button for a little while. It rebooted, then my nightmare just began...
I have tried everything, PRAM, command+R, literally everything. No change.
But when I plug a CD-ROM with USB, I can only here one BONG, just once, then white screen, Like waiting for something...
I took it to a service center in China, they told me the CPU had broken. SInce it's one month out of warranty, they wanted to charge me for like $250....
I really don't think that's CPU's problem. I checked the history, it seems like somebody else also had the problem before.
Can anyone give me some hints??? Thanks!!!!!! Or I have to take it back to America to check....Impossible, there are zero, as in none, zip, nadda viruses for OS X. If you have viruses on it they are for MS Windows and will not affect OS X. I suspect the hard disk has crashed, if you have backup then it's not a big deal to have it changed, just take it into your local Apple Store or AASP for service. If you have not been backing it up you may be in for a painful lesson on why backup is critical.

After upgrading to Lion, I went to open Mail and received the message that it needed to upgrade my Mail database - this may take a few minutes. The bar shows it is about 1/5 along and has been there for over 10 hours.
I tried quitting and starting again but it just jumps back to the same spot.It is quite large, but I have tried two of the fixes suggested and things now seem to be moving along.
(I was unable to seach properly before which is why I posted the question - it was a bit of a panic) -
After Lion upgrade, my email has been upgrading for 4+ hours
Is this normal?
I installed the Lion upgrade on my mid-2009 MBP. It went without any complaints. I have 8G of RAM and 200G free on the HD.
When I restarted after the install, logged in and started mail.app it said it had to 'Optimize' it and it started this process.
It has been running for > 4 hours so far. The window shows no indication of any progress being made and says it will take a few minutes.
The timestamp on my Envelope Index in ~/Library/Mail matches the start of that process, but nothing else in there shows any change.
Looking in the console I see the startup messages for the process, but no errors.
10/13/11 7:59:08.506 AM com.apple.launchd.peruser.501: ([0x0-0x124124].com.apple.mail[33082]) Exited with code: 255

10/13/11 7:59:13.653 AM Mail: Upgrading Library from 4.93 to 4.93
I can see that process is consuming CPU time and I did an lsof on the mail process and it shows that as the only open file under ~/Library/Mail that it has open.
mystic:~ jrh$ ps ax|grep Mail|grep -v grep
33118 ?? S 2:45.72 /Applications/Mail.app/Contents/MacOS/Mail -psn_0_1200421
mystic:~ jrh$ lsof -p 33118|grep /Library/Mail
Mail 33118 jrh 7u REG 14,2 91271168 370870 /Users/jrh/Library/Mail/Envelope Index
Sizewise ~/Library/Mail is 16G in size.
How long should this process take? I'm closing in on 5 hours with mail shut down.
thanks
johnI had the same experience and after 20 minutes I did it the crazy way. I disconnected it from USB iTunes and after 2 or 3 reconnections it happened the restore was ended and it was all OK.
Be carefull: this is something to recomended by Apple but... what can you do. ??? -
My iPhone 4 has been dead for 24 hours and I've been charging it for 12 hours and it still won't turn on. I have tried holding the lock button and home button down, even connected it to computer but nothing's happening, it randomly died on me.
Hi Lauren,
When troubleshooting power issues, we want to make sure we have followed all steps outlined in the following article:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
Will not turn on, will not turn on unless connected to power, or unexpected power off
- Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
- Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion.
Learn about LCIs and corrosion.
- Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
- After at least 15 minutes, if:
- The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
- The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
- Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
- If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
- If the display turns on, go to step 4.
- If the display remains black, go to next step.
- Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to
restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
- If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Thanks,
Matt M. -
I rented a movie, watched half of it. Had 27 days left until it expired. After 3 days, received a message saying the movie had expired and it appears deleted from my rental folder. Any ideas how I can get this movie back?
You would have to rent it again.
Once started the movie you have 24 hours to complete viewing.
How long do I have to watch a rented movie?
You have 30 days from the time of rental to watch your movie, and 24 hours (in the US) or 48 hours (elsewhere) after you've started viewing to finish it. Once the rental period expires, the movie will disappear from your iTunes library.
