IMac does not starts once on sleep mode after last Mavericks update... Anyone with the same problem?

Since the last update, when my iMac goes to sleep mode it seems that the mouse or the keyboard can wake it up. I have to do a "hard reset" everytime. Anyone has this type a problem?

Step 1
Take all the applicable steps in this support article. That's the starting point for any further efforts to solve the problem.
Step 2
If you're running OS X 10.8.5 or earlier, from the menu bar select
 ▹ System Preferences... ▹ Accessibility
If the checkbox at the bottom marked
Enable access for assistive devices
is checked, uncheck it and test.
If you're running OS X 10.9 or later, select
 ▹ System Preferences... ▹ Security & Privacy ▹ Privacy ▹ Accessibility
If any applications are listed on the right and have a checked box next to them, uncheck all the boxes and test. You may first have to click the padlock icon in the lower left corner of the window and authenticate as an administrator to unlock the settings.
Step 3
Disconnect all wired peripherals except those needed to boot, if any. Be sure to disconnect all USB hubs. If you use a keyboard or mouse plugged into a hub, plug the devices directly into a built-in USB port and remove the hub. Test.
Step 4
If you have more than one user account, you must be logged in as an administrator for this step.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
In the Console window, look under the heading DIAGNOSTIC AND USAGE INFORMATION on the left for Diagnostic and Usage Messages. If you don't see that heading, select
View ▹ Show Log List
from the menu bar. In the search box in the window's toolbar, enter "powerd" (without the quotes.) Select the last few messages that appear, if any, and copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).

Anyone with the same problem? My macbook pro is freezing on start up and I get the follin

My macbook pro is freezing on startup lately! It is wierd because I think the computer is still working, I can turn the volume up and down, and change the light in the keyboard and so on... But it still doesnt work.. I took a photo with my iphone? My macbook is kindda old I think it is from 2007. 2,4 ghz, Intel Core 2 Duo, 2gb mhz DDR2 SDRAM
I have installed version 10.6.8 on it..
Hope someone can help!

Did you ever figure this out? I'm having the same problem now... I have a 2008 macbook pro, running mountain lino and it's been doing this.. I tried booking in safe mode and got the same result. Single-user mode didn't even run, and it just kept starting and shutting down without the screen turning on. Really weird.
Anyways, if you found a solution I'd appreciate it if you could let me know. Thanks

Login issues from sleep mode after OSX maverick update

After upgrading to OSX Maverick on my 13" MacBook Pro, I am having issues with logging in after it being in sleep mode. Everytime I close the screen to go somewhere and open it back up to continue what I was working on I type my password in (I am the only user, no other user accounts) it acts like the password is wrong and the only way to get logged in is to hold the power button down to shut the computer off then power it back up, then I can login.

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 the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of certain system caches.
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. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
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? 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.

HT4623 Since I updated to ios my iphone now would not sync and so my music from my comp would nit transfer to my iphone, the prompt " download 10.6.3 " kept comin up but the certain app cannot be downloaded, anyone with the same problem? What did u do?

Since I used ios my iphone now would not sync. So the songs from my computer would not transfer to my iphone, I kept getting " download 10.6.3 version " but this app is impossible to download. Please help... Any suggestions.

You don't provide much info on which version of iOS you started with, what iOS you updated to and what version of iTunes is on your computer. Be nice to know also if you are using a Mac or a pc to sync.
But I'll make a guess that you have a Mac and it has an older version of OSX on it. I'll also guess that you updated to iOS 6.1.3 and now find that iTunes on your Mac will not recognize your iPhone.
iOS 6.1.3 requires iTunes 10.7 or later.
iTunes 10.7 and later ( iTunes 11.0.1 is the cur recent version of iTunes) requires Mac OSX 10.6.8 (Snow Leopard) or later. The latest version of OSX is 10.8.3.
If this is the case for you the only way you can sync with your computer is to upgrade your OSX to at least 10.6.8 and install iTunes 11.
Not all macs can update to OSX 10.6.8.

My iMac does not start.

My iMac does not start. When I turn it on, it stays loading in the half and doesn't continue. Some days before I had updated my iMac to Yosemite 10.10. Everything was ok but yesterday I decided tu reboot it and when it was turning on this happened, it kept stuck at the middle of the bar. I have the latest model of MacBook Air '13.

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 imac does not start anymore (stops at the screen with the apple and a rotating circle). An idea what I could try to make it start again?

My Imac does not start anymore.
==> What I have already done:
1) I tried with the tigger dvd to reinstall. It didn't succeed.
2) Via the single mode, when starting I got the message "disk0s2: I/0 error" several times. After that I got "Root device is mounted read-only"
3) Nevertheless, I tried the "fsck -yf" function. After checking "Journal HFS Plus volume", "extends overflow file", "catalog file"... and invalid record count
==> /dev/rdisk0s2 (hfs) EXITED WITH SIGNAL 8
Can someone advices me? I red on the internet I could reformat the disk... loosing all the data I didn't backed up. How am I suppose to reformat?
Thanks in advance,
Fred

Reset the PRAM: http://docs.info.apple.com/article.html?path=Mac/10.6/en/26871.html
Restart the computer while holding down your mouse button which if you hold it down long enough (5 minutes at most) should eject the disk
If the disk still doesn't come out at that point then you need hardware evaluation;
contact Apple, contact an Apple Authorized Service Provider, or make an appointment with an Apple Retail Store.

My iMac does not start up as usual. Start up disk is full message and I do not get normal desk top. Please can you help? Thanks

My iMac does not start up as usual. I now get a ' start up disk is full. You need to make space available on your start up disk by deleting files' message.
I am able to key my log on password however I just get the purple galaxy screen with no desktop.
If I try to use the keyboard I get a tone when pressing the keys.
Has worked perfectly well up until I got this dusk full message.
Can anyone help please. Thanks

Your going to have to follow the Data Recovery Efforts page here to be able to access your drive and remove files without booting the computer.
You can't open the iMac so you will need OS X booted from a external drive or via Firewire Target Disk Mode using another Mac.
https://discussions.apple.com/docs/DOC-3172
I would concentrate on Movies as this is a big source of large files to free up room.
Read Storage Drive here
https://discussions.apple.com/docs/DOC-3045
If you not handy with computers, your going to have to hire a local service or provide the info above to someone you know who can, it's not easy.

HT1751 imac does not start becouse cd i burn fast need help

imac does not start becouse cd i burn fast need help

andres:
Running Repair Disk from your install disk as suggested by neuroanatomist is the best first step. I have outlined the procedure in detail below, with suggestions for what to do if DU reports errors it cannot repair:
Repair Disk
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel, and report if it says anything but Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior
What’s a kernel panic may help you identify the black screen you saw earlier. If it does, post back and let us know.
Good luck.

My MBA does not start up from sleep

My MBA 13" mid 2013 (Mavericks) does not start up from sleep at times, or at least is very slow (1-2minutes)
As far as i remeber the only thing installed fairly resent is Virual Box.
It does connect to my iPhone when its connected to via USB but the sceen stays black.
Anybody else with this problem?

Hi bryan808-
It could be that the failure and installation of the update are simply a coincidence.
Back up. Then try removing all PCI cards and disconnect all external devices except your monitor, keyboard, and mouse. If that configuration will wake from sleep then start adding devices and/or cards one at a time until you find the culprit that keeps your machine from waking.
If you are really running a G4 you will have better luck posting in the appropriate section of that forum: Ctegory: Power Mac G4

My imac does not start and asks for bootdisk

i bought a new imac and connected it with internet to upgrade the drivers. Power went off... and now imac does not start.
When it starts it asks for the boot disk and no boot disk came up with my mac.
Please help how can i reinstall mac.
thanks

None of the options work. I press the power on button keeping the option and R button pressed but the only option that appears is
First blank white screen appears as soon as i power on (option R is pressed) and then the following message
No bootable Device -- Insert boot disk and press any key
(Ethernet cable is connected but it does not go for internet recovery either)
No more activity.
Also if you can guide from where I can download OS X Lion for reinstalling it to the imac, please.
Does every mac come with a restore/bootable disk or not? We ordered two macs but did not get any disk with any of them.
Anxiously waiting for help....

My iMac does not wake from power safe mode

My iMac does not wake from power safe mode when addressed over the network from my Apple TV, until I send a "wake on LAN" command from a utility on my iPad. Is there anyway this can be done directly from Apple TV?

Tons of similar reports all over the web - especially on ATV3 - but no solution, seemingly. Hopefully a software update will fix it one day soon. Sorry.

Ipad is not connecting to wifi in sleep mode after iOS 6 update

I used to be able to receive FaceTime calls when ipad was in sleep mode but ever since this past update I don't. I had problems like everyone else wi connecting to the Internet but I was able to fix that. Is there any way the ipad can stay connected while in sleep mode.

Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
iPad: Issues connecting to Wi-Fi networks http://support.apple.com/kb/ts3304
iOS: Recommended settings for Wi-Fi routers and access points http://support.apple.com/kb/HT4199
Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.
