Don't post in all caps. Besides being more difficult to read it's tantamount to shouting and is considered rude in forums. What problems are you having? What model Mac do you have, how much RAM and free space on the boot drive?
Boot into the Recovery volume (boot with the Command + R keys held down) and try the following in order as needed:
1 - select Disk Utility and repair both the disk and disk permissions. Reboot normally.
2 - reinstall the Mavericks system.

Update Error and now computer is acting strange

ok so i was downloading the new update from mac. I left my Macbook Pro by itself for a while and came back to see just a blue screen. I left it for a while and it was still blue having never restarted. I have no idea if the update was successful now. And now when i boot my mac 3 windows pop up and say "the disc you inserted is not readable. and when i go into disk utilities instead of saying Macintosh HD it says disk0s2. I think my computer is acting normal besides that and i purchased this mac only a few months ago. How do i fix this or make it go back to normal?
I have time machine too in case i have to do something drastic.

ok this does not seem to have anything to do with the update.
i just read this

Computer doesnt start up properly ?

Any help out there ?.
Had to unplug computer the other day ,as it was blocked and couldnt close down any other way . And since then doesnt start up properly,either takes a long time to start up or just remains with progress bar ,say looking for local discs .
I have it set to turn on automatically at 6.30am and this doesnt work anymore .
Any genius out there ??
Thank you.

Hello martin,
The first thing to try would be to reset the PRAM.
Resetting the PRAM and NVRAM.
If that does not improve things then run Repair Disk from your Install CD.
To do this: Insert the Install Disk 1 into the drive and then select Restart; when you hear the chime hold down C key until the apple logo appears.
This will take you to the installation software, but you do not want to install.
Select your language, then go up to the top menu bar to Installer and navigate to the Disk Utility application.
Select the start up drive, then go to the First Aid pane where you can click on Repair Disk.
If it finds errors, repeat the process until it reports no errors.
After these repairs, quit the application, and restart normally.
Once restarted normally run Repair Permissions from the Disk Utility application found on your hard drive in Application/Utilities.

Downloaded security update 2014-002 now computer is freezing. Can I uninstall it?

Can I uninstall security update for Lion 2014-002? Afte repairing permissions before and after the download, the computer is freezing and needs restarting if not in use for several minutes.

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
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.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was started. Now clear the search box and scroll back in the log to the last boot time after you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V. Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post any other kind of report—it will be very long and not helpful.

Tried to replace RAM but now computer not starting...PowerMac G5 dual 2.0 - are my hard drives safe? What's up?

Hello - I tried to increase the RAM in my old and trusted Power Mac G5 (dual 2.0...2005) tonight and now I'm in trouble. It has only 4 slots for RAM. It came installed with 2X256 and 2X512 ram cards. I bought 2X 1GB of Ram from Crucial.com after sending them the specs of my computer they assured me it was the right RAM. I installed the RAM just how the youtube tutorials instructed.... I replaced the 2 256 cards with the new 1GB cards and closed up the computer......note: I also "dusted" the inside of the mac very carefully and lightly with a barely damp rag.....
I plugged her in and the power button light immediately went on but the computer did not. The button wouldn't respond to being held down either. No sign of a startup or a fan noise. Nothing on the screen, no signal.... Nothing..... So I tried reversing the order of the RAM, I installed the 1GB along with the 512's. Nothing again, just the light turns on when I plug her in. Then I returned the RAM to the original configuration.....again NOTHING...just the light on.
I reset the SMU. (little button underneath the RAM area) I haven't tried to reset the PRAM yet, but I'm pretty sure that will not work either as she is not starting up at all....just the light is on... I didn't get a noticeable shock or static spark during the entire operation either. ****....whats up?
Are my Hard Drives safe in there?
Any ideas out there? Thanks in advance to your advice, T

Ouch! That was not the way to get dust out. Running that damp rag anywhere near an electronic component, even if you were wearing a properly grounded writs strap, was way dangerous.
Did you lay the machine on its left side when you replaced the RAM? That is much safer (though the recommendation only shows up in the service documentation, not the user guide, for some reason).
What I would do at this point is to remove all RAM and try to power the machine. If other stuff is OK, you won't start but you will see the lunar LED flashing in a repetitive pattern above the power switch. If you don't see that happening, then things are exceptionally serious.

Installed new RAM now computer wont start up

I just installed 2GB of RAM in my iMac and removed the 512mb card it had originally.when i pressed the power button it beeps fast a few time then the fan starts working really fast. The screen doesnt turn on only the sleep light blinks as the fan runs. I replaced one of the new cards with the original 512mb card and it starts but when i check the memory the slot where the new 1GB card appears "empty" why could this be? did i install incorrectly?

When you install new RAM you have to push much harder than you think you should. You won't damage the RAM, but you have t give a mighty push to seat it, make sure you hear a click.

Updated security 002, now computer is freezing up

This morning I downloaded the security update 2004-002 for OS X. I repaired permissions both before and after the download.
I left the computer for a bit and when I came back I could not access the desktop in any way. I had to force quit and restart. I happened again later this afternoon. I can't think of any other thing I could have done which would be causing this problem.
Thank you for your help!

Dear Mr.Brody,
I am sorry that I did not respond to your recent reply to my freezing computer problem after downloading the security update, but I missed seeing it in my email, before I saw the others who responded.
Those other people provided some answers, but before I could use themthe problem of freezing seemed to resolve on it's own.
My answer to you is that our hard drive is 499.25 GB and it has 83.51 GB available.
The computer is no longer freezing, but I have a different problem. I have tried to burn a few cd"s with about 20 songs on them. When played on our cd player through the stereo system they fail after 3 songs play. The playlists will play on the nano through the stereo system and through the computer without failing, but not on the cd player. I tried some older cd's I had burned a month ago and they work just fine on the cd player.
All this has happened since the security download. I have not tried to do a restore from the backup. My husband has reservations about that. Also I saw that someone else had tried that and it did not work for them.
Thanks for your help in advance.

Did i lose all my files? since my computer doesnt start back up..

I live in a pretty humid place but never had any problems with my computer before. since two days ago it doesn't come back on. it shows a blue screen with a little finder-logo and a question mark- but it won't go past that. the computer makes a strange ticking- sound when i turn it on and it heats up really quickly.
I don't care so much if the computer is not going to survive but the information that is on there is so important, can i still save it?

Welcome to Apple Discussions, kikaway!
There are several options that may get the data off your computer.
* Have you tried starting up from the original CDs that came with the computer? If that works you may be able to back up your file to an external storage device of some kind.
* If you can get access to another Mac with a FireWire port, and a FireWire cable, you can may be able to start your computer in "Target Disk Mode" by holding down the "t" key when starting up. This will cause your computer to look like an external hard drive to the other Mac.
* Someone with the right tools and skills can take the hard drive out of your laptop and read the data off onto another computer.
All of these options assume that the hard drive is still working, at least somewhat. Depending on how vital the data is to you, there are places that can recover data by taking apart the actual hard drive and putting the data platters in other drive mechanisms. This may cost hundreds or even thousands of dollars. I have never looked deeply into it.
Good luck.

Failed attempt to restart after updates, MacBook Pro now frozen on start up.

Hi, please forgive my ignorant description, I am useless outside of emails and documents.
This morning I clicked yes to update my MacBook Pro. I think it was on mountain lion and had an upgrade bundle. During the restart the charger plug was dislodged for a few seconds. It came up with an error message (along the lines of "not all updates successful" and prompted for a restart. I restarted and after the start up sound I am frozen on a white screen that says -
panic (CPU 0 caller 0 xffffff8028e59241): "Unable to find driver for this platform:\"ApCI\".\n"@/SourceCache/xnu/xnu-2050.20.9/iokit/Kernel/IOPlatformExp ert.cpp:1548
Further down it says Mac OS version not yet set.
I tried turning it off and on again and ended up back at the same screen message. Also tried control option escape and nothing happens. I live in regional SE QLD, nearest Apple store is in Brisbane. Is there anything I can do or do I have to wait till I can get it to a professional?
Thanks.

Boot into your Recovery partition (if you can) by holding down the command and R keys whilst booting. Once there elect to resinatll the OS (you may need your Apple ID and password for this). You'll not erase any data, etc., by installing a fresh OS.
Once your OS install is complete, you can restart and go through the update process again, this time remembering not to unplug from mains while the updates are installing.

My computer doesnt start up correctly

I have lion reinstalled since i had a trackpad issue and now after the restart i only get to the gray fabric screen but nothing happens from there, i can only see the mouse pointer and thats it.
There is no picture with a blank space to write my password anymore.
What can i do????

I have tried that one too. The only thing is that i press the option button while starting up in order to select the disk from where i want to start.
Having said that, I verified my disk on disk utility and it has no problems, i repaired all permissions, reinstalled lion and recovered lion from a previous version since reinstall didnt work.
I have done all of these and havent had any good results.
The only thing that i did before having this problem was that i reseted the pram.

After the latest update for firefox, now when I start firefox up I keep getting a pop up window that is a Java Script Application that says TypeError:Components.classes['@softage.ru/skype/skypeFfExtension;1']is undefined.

After closing this Firefox seems to work fine but this happens everytime on startup. How can I get rid of this pop up window starting everytime? Can I re-install firefox? Would I lose my bookmarks etc?

Once I disabled my Ask.com toolbar (that was installed when I installed FoxIt), the error went away.
