2008 iMac hung after reboot. Recently installed Mountain Lion.

My 2008 iMac will not reboot after freezing. I had recently added additional RAM to get to 6GB prior to upgrading to Mountain Lion. Everything was fine for two days. However, yesterday Bluetooth was dropped and not showing as being avaialable (managed to fix that). This morning it froze and will not reboot. I am getting the grey screen of death even after trying to reboot in safe mode.
I have also tried an SMC reset with no luck.
Any suggestions?

For what it's worth a situation very similar to yours happened to my 2007 iMac last Saturday. Thanks to Time Machine I was able to erase my hard drive then restore it from a back up. However in no time flat, after I'd opened a few apps, it crashed again. When I attempted another restore it crashed *during* it (grey screen of death!) and I had to conclude my iMac's hard drive had died.
I've since heard, from both an Apple Store Genius and the techies who replaced my busted drive, that an iMac's hard drive lifespan is often around 3 years.
Maybe your hard drive has died?
Good luck! It's very frustrating.

I just recently installed mountain lion and an update for SMC firmware to install power nap. Everything is working except for the menu bar, the icons native to the system do not respond, and features like the clock and battery meter freeze.

I just recently installed mountain lion and an update for SMC firmware to install power nap. Everything is working except for the menu bar, the icons native to the system do not respond, and features like the clock and battery meter freeze.
When I mouse over the icons, the rainbow appears as if it was processing something. The problem is eliminated when I restart my computer but it comes back after a while.
I guess I cant make a backup copy and restore the whole disk because the copy would be made with this error.
Can anyone help me? Anyone with the same issue?

Update: I was able to test out the HDMI adapter as well and the same issue occured. I'm stumped. 10.8.1 maybe.

Problem waking imc after sleep since installing mountain lion

I installed mountain lion and since then when the computer sleeps for more than 1 hour, I come back to a blank screen. Initially I could use the mouse as a chalk board eraser and uncover the login most of the time. This showed a white box erasing a black screen. Recently, I come back to a grey screen with a black box that does not move in response to the mouse or arrows. I have to do a hard shut down and then restart to use the imac. I run Norton antivirus scans regularly and they have not found a virus.

Thanks Paul. I tried it and it didn't work. I completely removed the program.There are reports of MAC mountain lion viruses I found online and I still worried. I did not find any other cause for the situation though. Interestingly, Norton came out with upgrades that claimed to fix the problem I was having and stated it was now compatible with the new OS.
Downloading the newest version of Norton and installing it from scratch ( my subscription was still good) did resolve the issue.
I believe there was some part of the old program that hung around and was not uninstalled completely. This must have been fixed with the latest vs installation.
I have used Norton almost as long as I have been using Macs. ( since the first Macintosh). I have found and been able to remove viruses before. I am skeptical that any OS will eliminate the need for virus protection.

After downloading and installing Mountain Lion my iMac 27" is nearly non-functioning. SLOW beyond endurance on my part! This same thing happened after downloading Lion last year. An Apple advisor had me reload it. Still terrible! Help?

Has anyone had this problem? Any solution(s) welcome!

Thanks for the info. I'll have to check this later this evening, since I'm in my office presently.
However, I do think it is (was) indexing.

After installing Mountain Lion iMac warmer

After I have installed Mountain Lion, I hear for the first time the fan on my iMac running. It's a iMac11,3 (mid 2010 model) with 4GB RAM and a standard configuration. Granted, it is mid summer and around 85 degrees but we had such warm days before in the last two years. And for the first time, the iMac gets very warm and the fan starts to run. It happened right after the install of Mountain Lion so that I don't think it's a problem with the fan.
Has anyone seen similar situations?

As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

Mac Pro intermediate black screen at boot after installing mountain lion

I have a 2008 Mac Pro tower, but since installing Mountain Lion I now get a random black screen at boot. Unplugging the apple cinema 20' power supply for 15 minutes seems to clear the fault. Have had no such problems with other OS until Mountain Lion, seems OK when booting to Snow Lepoard on my other drive?
Anyone have the same fault?

Thanks for trying the help! I tried every version of start up, but with no screen it was no good..
Finally solved the problem, it was the ATI HD 2600 XT graphics card that was dying a very slow death.
Replaced it this morning with a GT120 Nvidia.
Anyone with this card should Google it, as apple did a big recall on these..

Problems with App Store since installing Mountain Lion

I have recently installed Mountain Lion and since then have been unable to use the App Store. When I launch it comes up with an error message stating 'App Store cannot verify a secure connection with the App Store.Would you like to connect anyway?' If you hit continue the application flashes black and white but goes no further. Has anyone else had this problem and what could be done about it.

Yes at work and no at home but the problem occurs regardless of this

HT4628 My macbook pro will not automatically reconnect to the wifi after a sleep. This has started after having upgraded to mountain Lion (10.8).

Hi
After I have installed Mountain Lion (10.8) - my macbook pro will not connect automatically to my preferred wifi network. It used to do that on the previous versions. It seems that the mac does not recognize the preferred network, as it asks me to choose a network after evey sleep/restart. I have modified the network preference to have my preferred netwrok at the top of the list. I have tried with/without checking the "ask me before joining a new network". It still behaved the same.
Thanks
Eitan

Try making a new network connection and renewing the DCHP lease as detailed here:

Help - I just installed Mountain Lion and now my MacBook Pro crashes all the time

Hi everyone. I've recently installed Mountain Lion on my MacBook Pro and now it randomly crashes. I tried finding the pattern (maybe when I open a specific app, or go through a series of steps) but nothing, it just happens, and it feels random.

Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:
Kernel Extensions in backtrace (with dependencies):
         com.apple.GeForce(6.4.0)@0x82ac4000->0x82b7afff

            dependency: com.apple.iokit.IOGraphicsFamily(2.2.1)@0x8301b000
Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…
So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. They should be more than willing to install a new logic board at no cost. I have no idea why this faulty GPU is making the headline here on the MacBook Pro forum so often now - could it be because Mountain Lion is just bringing the issue to a head more readily? I don't know - I only know that we're seeing more and more of these kernel panics of late.
Good luck,
Clinton

HT3775 i installed mountain lion. Which quicktime do I need?

I recently installed Mountain Lion. Now i have trouble with certain quicktime movies not playing.

There is a Mountain Lion forum:

After installing Mountain Lion iMac i5 runs slow and hard to wake up

After installing OS X10.8 (Mountian Lion) my iMac i5 with 4GB RAM seems to run slower. It also is hard to wake up after sleep mode. Sometimes it even just freezes and when I force quit all the apps the apps can never be launched without a hard reboot.

Open Disk Utility (Application - Utilities - Disk Utility) Repair Disk Permissisons 2-3x. If that doesn't work then restart in Safe Mode to clear some caches and then restart normally. If it still has problems then your install is corrupt and you need to re-download and re-install Mountain Lion from the Mac App Store.

I have bought a new imac late 2012 and I want to wipe clean my 2008 mac and install Mountain Lion on the old computer for my kids to have

I have bought a new imac late 2012 and I want to wipe clean my 2008 mac and install Mountain Lion on the old computer for my kids to have.
What do I need to do?

Boot your Mac from the System Install DVD that came with it, and erase the HD using Disk Utility. Then, reinstall the OS from the disc. Give the disc to your kids since it must always accompany the Mac it came with.
After the OS installation is complete and the Mac restarts to begin its new owner setup procedure, just shut down the Mac. Your kids can take it from there.
If you purchased Lion or Mountain Lion from the App Store, you cannot transfer it. The Apple ID you used to purchase it is required to maintain and / or reinstall the OS. Unless you want to supply your own Apple ID to your children for their use, they must purchase their own copy of Mountain Lion using their own Apple ID.
If they do not already have an Apple ID and you want them to have Mountain Lion, you will need to create one on their behalf. This does not change the above procedure - just give them the Apple ID and password you create in addition to the Mac and its discs.

I want to install Mountain Lion on my 2008 iMac. My current OS is Snow Leopard 10.8.6. I've heard ML may be too much for this iMac. I would appreciate anyone's advice.

I want to install Mountain Lion on my 2008 iMac. My current OS is Snow Leopard 10.8.6 and there is 4GB RAM. I've heard ML may be too much for this iMac and may slow it down. Has anyone had any problems with this upgrade?

See > http://www.apple.com/osx/specs OS X Mountain Lion requires a Mid 2007 iMac or newer, and your iMac can run Mountain Lion without any problem. 4 GB of memory are enough for Mountain Lion, but if you are going to use heavier applications, maybe you will need more RAM
Before upgrading, you must make a Time Machine backup and/or a clone with Carbon Copy Cloner, and check that your applications are supported > http://www.roaringapps.com

Imac does not recognize my usb after installing mountain lion

My imac don´t recognize my usb after installing mountain lion, also don´t let me see all my photos in jpg format

What is "my USB"? If it's an external USB device, is it ML compatible?
Which app do you use to open JPGs? Is it ML compatible?
