I deleted my extensions manager and now my Mac won't start up. Please Help!!
I have an IMac, 24" model, running OS X. For the past several days, little warning windows have been popping up with this annoying beep, telling me that my computer was infected with various viruses. 4, to be exact. Also, while on the internet, random pop-up windows have appeared, so I thought I did have a virus. So, to correct the matter (or attempt to), I deleted my preferences folder from the system folder, as well as the extensions manager.
Now, the computer won't start up past the white logo screen with the turning gear thingy. I've tried resetting the PRAM, and starting in safe mode, and safe mode with the progress screen, and even something there while holding the option key (that one gave me an icon of my HD, but clicking on it took me back to an endless wait on the white screen). I've tried starting from the disk that came with the computer (I held the C key) but not only doesn't the computer start from the disk, it spits the disk out. I don't understand. The computer was fine until I deleted the ext. mgr and preferences, so it can't be that the computer went bad or something.
I don't know what else to do here. I do have an extended service warranty with Best Buy, but I wanted to see if there was some way to fix this before hauling this thing off to the store. Any suggestions? I'm desperate here, because anything and everything I've tried (based on all the try-this and try-thats I found on the internet), nothing has worked.
Please help.
Thanks in advance.Well done! You've succeeded in turning your Mac into a useless brick.
Deleting the System/Library/extensions folder and the associated manager removed most of the functionality from your OS.
And all to get rid of what sounds like the MacDefender trojan or a variant.

You may have a slim chance of recovering if it will still boot in Target Disc Mode; in which case you can use another Mac to install the system remotely.
And I doubt your warranty with Best Buy is going to cover user "error."

HELP! I had a Flashback Trojan/Malware on my Mac, I deleted it in trash, and now my Mac won't start.
At first my Mac Finder showed n81, n82, etc when you right-click it, instead of the commands " open new finder window", "hide" etc. I also noticed that sometimes, when I would go to sites such as facebook, it would redirect to a different site and I'd have to type in the address again to get to the site. Nothing else was wrong with it. Safari was not shutting down. It wasn't slow.
I did some research and found that I probably have the Flashback Trojan/Malware virus (whatever that is?) And so I followed what some people did (which got their mac fixed) .. I downloaded clamvax and tinkertool to find the malware (hidden files) and I deleted it in trash.. my computer seemed fine but when I restarted it, it wont turn on anymore.. the screen remains blue, the mouse could still be moved, but it stays that way..
did I lose all my files? am I being hacked as we speak? Is this virus very dangerous?! I am very paranoid and know nothing about this kind of stuff so please help!
BTW, the malware was from the game Farm Frenzy.. I have no idea how I got this... I never play online games.@Thomas, Thanks for jumping in. I had to take my wife to a Doctor appointment and things went down hill from there.
I note that you are using Mac OS X 10.5.x. It's important to understand that the Java vulnerabilities that allowed this malware to get established on your machine cannot be fixed in 10.5.x. You would need to upgrade to at least 10.6 (Snow Leopard) to be able to get a version of Java with those vulnerabilities fixed. (Correct me if I'm wrong there, Al!)
That's 100% correct. Natalia has the distinction of being the first OS X 10.5 user confirmed to be infected by Flashback as far as I can tell. That operating system is becoming increasingly dangerous as the days go by. The OS has not been updated since Aug 2009 and the last Security and Java updates were in June 2011. There is no XProtect system and more and more third party's have dropped support in updating their Applications.

I actually ran disk utility, and it said that the Macintosh HD is fine... I also tried safe mode/safe boot and did the FSCK command.. even that said that my laptop was fine? but somehow it still stays blue when I start up!
And I think it probably is fine, except that something is hanging during the initial loading process. Could be most anything.
As for my files, I appreciate your advice but I am scared I might do something wrong and mess my laptop up even more!
There is almost no chance of that and at this point it should be obvious to you that if the files on your laptop are that important, you should already have a backup.
I will take it to Apple and hopefully they can help me... because it seems that my files aren't wiped out... yet... It still displayed that I had my files in there..
One word of caution, then. I have been told that Apple has instructed their support folks not to attempt to clean up a malware infection. If I were you I wouldn't bring it up unless you have to.
By the way, while the disk was running, it was making very loud noises.. humming/grinding/etc... what could this mean?
Only one thing in my experience, you're hard drive is toast. All the more reason to try and get all the data you can off it immediately.
The only way to test it is to do a surface scan which Disk Utility cannot do. You would need a third party utility to do that. If it tells you there are bad sectors, that is 100% proof that it's going bad, as modern hard drives repair themselves of bad sectors until they run out of reserves to substitute. -
I was trying to install windows, it didn't work. Now my mac won't start. Please help!
I Was installing windows through Bootcamp. There was an error that said that recovered partition should be NtFS type. Now it quit installation and shows me am error message saying, "No bootable device -- insert boot disk and press any key". How do I go back to my Macintosh from this? :/

Upgraded to mavericks and now the mac won't start.
It's looping between a grey screen that says "your computer restarted because of a problem..." and code that says "panic CPU..."
I started disk utility and it says that my drive is unrepairable
Any advice?You know what, I think I just solved the issue. Using media browser, I was able to import one MXF file because it combine all of the individual clips into one clip.

Mac won't start after failed OS upgrade
I attempted to upgrade from Leopard to Snow Leopard using an installation disc. The installion failed and now my mac won't start. It hangs on the apple logo screen for about 2 minutes then dies. I've tried booting from the disc and using the repair disk utility but I get an error saying the disk can't be repaired and instructing me to back up my files and erase the disk. Problem is, I can't get to my files because all I can do is boot from the disc drive. Can anyone suggest a way get the installion to work, or a way to back up my files?
iMac is 3 years old, 4 Gb ram and 2.66 Gh processor
Any help would be much appreciated.Possibly we can save some of the files.
When booted from the Install Disc...
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
Hopefully you have another external drive and can Image the whole internal drive to an external. -
I was going to use iExplorer to try to copy Notes from iphone 4 to my iMac but changed my mind after downloading iExplorer to my iMac. Deleted iExplorer from my iMac. Now my Mac won't recognize when my iPhone is plugged in. Is iExplorer the problem? How do I fix this?
I am using the Yosemite OS on mHi TakesTwo2Tango,
Thanks for using Apple Support Communities. It sounds like you should definitely be seeing a plus sign after tapping Edit, so I would try a couple relatively easy things (closing the Music app, resetting the iPhone):

Help! Just did the Update (ML 10.8.4) after receiving a new HD since mine crashed last week and the shop didn't update it back to Mavricks which I had previously done...and now my Mac won't let me past the log in screen even with correct password entered. It just spins like I'm logging in and then goes back to the user log in screen. I did the process where I restarted and pressed control S and created a new user and password, but once created same issue and can't get passed that screen.
Super frustrated and any help is appreciated!I have decided to dedicate this thread to the wonderful errors of Lion OSX. Each time I find a huge problem with Lion I will make note of it here.
Today I discovered a new treasure of doggie poop in Lion. No Save As......
I repeat. No Save As. In text editor I couldn't save the file with a new extension. I finally accomplished this oh so majorly difficult task (because we all know how difficult it should be to save a file with a new extension) by pressing duplicate and then saving a copy of the file with a new extension. Yet then I had to delete the first copy and send it to trash. And of course then I have to secure empty trash because if I have to do this the rest of my mac's life I will be taking up a quarter of percentage of space with duplicate files. So this is the real reason they got rid of Save As: so that it would garble up some extra GB on the ole hard disk.
So about 20 minutes of my time were wasted while doing my homework and studying for an exam because I had to look up "how to save a file with a new extension in mac Lion" and then wasted time sitting here and ranting on this forum until someone over at Apple wakes up from their OSX-coma.
are you freaking kidding me Apple? I mean REALLY?!!!! who the heck designed this?!!! I want to know. I want his or her name and I want to sit down with them and have a long chat. and then I'd probably splash cold water on their face to wake them up.
I am starting to believe that Apple is Satan. -
Hello
I was having some problems with my Imac, for a while it was slow and often disconneceted from my wifi, while this one worked perfectly (tested with other devices)
I thoug i might have a virus, so i downloaded an antivirus (mac keeper) and started checking.
I also did a scan of my computer using Console or something from the utilities, and then a folder popped witha file I had canceled a while ago. I canceled the file and then my Imac continued to be slow.
i then restarted my Imac, but when it started, the usual grey logo of Apple appeared, and then it shut down suddently.
I tried to reboot it holding the command key and R but nothing, and then i tried holding the shift key and a bar appeared, and at half of the bar it sut itself down again.
I think it is probably a preoblem because I may have cancelled some of the system files from a folder called "private" in the "documents" folder.
Is there any way I can recover some of my files? maybe all of them? I hope so because I have some important files there
Is this a thing I can do myself or do Ineed to go to a MacStore to repair it? Will I need to change HD or just to format it and reinstall? also if there is any way i can recover some of my files that would be great.
Thanks
Ludo
P.S. problems appeared when i installed the Mavericks version.If MacKeeper corrupted the Recovery partition then even I underestimated its potential for damage. Garbage "cleaning" apps will cause misery but I have not found that the Recovery partition to have been affected by using MacKeeper or anything like it. I doubt that it did so, but I have learned not to underestimate the potential for such things to result in system corruption.
Before concluding your Mac has a hardware failure, try booting OS X Internet Recovery by holding command option r on startup (three fingers). That will force your iMac to bypass the Recovery partition altogether, and convey the ability to create a new one.
An Internet connection will be required (wired or wireless).
At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red. If Disk Utility reports "The volume Macintosh HD appears to be OK" in green then you can be reasonably (though not completely) assured your hard disk is in good working order.
Assuming the HD remains usable you can then use Disk Utility to erase it. Reinstall OS X, restore your essential software and other files, and don't reinstall the junk. -
Mac won't start (Kernel Panics)
Hello,
My mac won't start up. It turns on, gets as far as the spinning circle and apple logo then a dark screen comes down with a Kernel Panic message. This occurred roughly three months ago and I ended up taking the mac into the regent street store where it was fixed under apple care warranty. My care has now run out, and the 90 day repair warranty has expired but the problem is back so obviously hasn't been fixed properly. Is there anything that can be done about this?
Every time I boot up the computer the message appears, I have tried rebooting with the safe option as well as re installing OSX from the original disks. The install completes successfully but upon restart it pops up with the original kernel panic message.
Luckily I have everything backed up so am prepared to try anything to get it running.
Thanks.Let us know, but since you obviously have another machine, have you tried Target Disk Mode and then Disk Utility?
use TDM to access Disk Utility.
1. Click the First Aid tab.
2. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
3. Select your Mac OS X volume.
4. Click Repair. Disk Utility checks and repairs the disk.
Please post back, -
My mac won't start up it keeps on chiming tried o
My mac won't start had a power cut and now all it does is chimes.
Tried to press options and c but still continues to chimeYou could try the ol SMC reset.
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
http://support.apple.com/kb/HT3964
If it still does not work, Restart using your 10.5 Install DVD as the boot volume holding down C from chime sound to apple logo appearance, then after selecting your language from the menu bar go to Utilities > Disk Utilities, and run Repair Disk on your Mac's HDD. Afterwards, exit DU, exit Install, restart normally. -
Every other day, my mac won't start up
every other day, my mac won't start up. my keyboard would light up and i hear the system start but nothing is appearing in the screen. i would have to press the start button until the screen actually shows up.. why does it do that?
Have you just tried repairing with Disk Utility?
Repair the Hard Drive and Permissions - Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu. -

Any help would be appreciated.
I have removed the ecp site from default site and attempting to rerun SP1 now. I do not have high hopes. :(Hi,
Thanks for your response.
From the error description, you need to manually remove the ECP with IIS manager in both the Default Web Site and the Exchange Back End firstly. And then continue the upgrade to check the result.
Hope this can be helpful to you.
Best regards,
Amy Wang

Your Mac won't start up in Mac OS X (Mac OS X 10.3.9 or earlier)
I just got off the phone with an AppleCare agent. My iBook OS 10.4 wouldn't start - it just went to a blue screen. I'm happy to say that the agent got everthing working again and said that she would email me an article that would help if it ever happens again. She emailed me "Your Mac won't start up in Mac OS X (Mac OS X 10.3.9 or earlier)" I have 10.4, is this article any use for me or was I emailed the wrong articel. Is there an article "Your Mac won't start up in Mac OS X (Mac OS X 10.4 or later)"????
