My iMac 27" (mid-2010) won't boot up.

I had recently received a warning that the hard disk was nearly full. Now what I get is the grey screen with the apple logo and spinning 'gear'. For a brief time (1-2 minutes) there will be a status bar below the spinning gear. This appears to show about 5% progress, then disappears and just the logo and spinning gear are left and it just stays like this. I had hoped installing additional RAM would help and upgraded from 4 to 8 GBs (purchased through OWC). This did not help. I have tried booting up in safe mode (holding down the shift key) and the "DVRAM zap" (holding down the Control, Option R & P keys) when starting the computer. I have also tried starting using the OSX Tiger install disk (10.4.3) while holding down the C key. I keep getting the same result. One thing to note is I am trying this with the wireless keyboard. I do not have a USB keyboard. Will these attempts be "recognized" with a wireless keyboard or do I need to use a USB keyboard? Also, not sure what OS I'm running currently.
Thank you for your help.

Tiger will not boot a 2010 Mac. The oldest operating system that might work is Snow Leopard (10.6). Being it is mid-2010 iMac, it has to be the pre bundled 10.6 installer disc that came with it from Apple labelled iMac. If you are missing that disc, call AppleCare.
DVRAM is not what it is called. NVRAM and PRAM can be reset, if the machine is under 4 years old. Over 4 years old, the PRAM battery may be too old and cause the machine to be frozen until the PRAM battery is replaced.
A too full hard drive often lends itself to a corrupted directory and trouble booting up. Once your hard drive exceeds 85% capacity, it should be cleared, and excess data archived away on other other media that you don't regularly backup in a clone or otherwise.
Upgrading the RAM may help speed things up, but does nothing to help the hard drive is too close to capacity.
So the big question is, is your data backed up or not?
If not, you may need to get a larger hard drive to recover data to as documented here:
https://discussions.apple.com/docs/DOC-1689
You need to get a USB keyboard, preferably an Apple or MacAlly if you want to boot the machine with the startup manager.

MacBook Pro 15 '' (mid 2010) won't boot up

Hi,
This is my first post in the Apple Foruns, been lurking for awhile, however, have never run into any problems with my MacBook Pro.
A couple of days ago, I hav had several situations where while using my Macbook, it would crash, the Beachball would come up and he would not respond to any commands, only by pressing the power button to Force Shut Down would work.
After this started happening, during a boot, I got the prohibitory sign .
After this happened, everytime I boot it up, it sometimes boots, but most of the time, it doesn't. I have tried:
- Safeboot (Shift-Command-V - and I do see an error 19 that mentions that the System cannot mount the drive)
- Tried booting from my BootCamp partition, but that also does not boot, mentions that it should run the StartUp repair from Windows, but will not load.
I think this might be a faulty HDD, so in one of the times I managed to boot to OS X, I used the Disk Utility, Verified the Disk and it stops midway with an error stating that the "Volume is corrupt" and must be repaired using the Disk Utility from the Mac OS X Install DVD.
As I do not know where my Install DVD is, I tried booting in single user mode, performed a fsck, which detected some issues, repaired them (ran fsck 3 times before it gave the "Volume is ok" message) and rebooted.
Got in to OS X, ran Disk Utility again just to double check, and it gave the same "Volume is corrupt" message.
Booted to Single User mode once more, ran the fsck again, which gave the message that the "Volume is ok".
I wonder, since I carry my laptop around with me, no second skin, and have to say it has suffered some several bumps and shocks, it can be the HDD which has died?
This was hinted by:
- Safeboot (Shift-Command-V - and I do see an error 19 that mentions that the System cannot mount the drive)
- BootCamp partition also does not boot, mentions that it should run the StartUp repair from Windows, but will not load.
- Having the Volume stated Corrupt by Disk Utility inside the OS, but having fsck stating it's ok
Now, I am confortable with buying a new HDD, install it and re-install the OS, but should I still try to format my current HDD and re-install the OS on it?
Also I do not have my Install DVD's, if I phone Apple (I'm from Portugal) will they provide Replacement DVD's?

...and the boot up media i'm using are the origianl 10.6 and 10.5 disc.
Your mid-2010 computer requires a minimum of OS X 10.6.3 to boot. Only the disc that was shipped with it contains the necessary version. A retail 10.6 disc can't boot it, and no 10.5.x disc can boot it. Use the one that was shipped with it and no other.

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard (via my MacBookPro), either from the HD or DVD drive. Can't get it to run Hardware Test. Disk Utility says disk OK - files are there. What can I do?

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard. I erased and re-installed by putting the iMac in Target Disk mode and usin my MacBookPro as the host. But after numerous attempts I still can't get it to boot either from the HD or DVD drive. I just get the white screen after the wheel stops spinning. I can't get it to run Hardware Test - just get the white screen. If I use Disk Utility via my MBP it says the disk appears OK. All the Snow Leopad files appear to have been installed. What can I do?

Perhaps you installed the wrong version OS X onto the iMac, you can't use the disk from another Mac.
clean the disk.
If it's not working then use this method to create a bootable 10.6 USB from the iMac machine specific 10.6 disk or the 10.6.3 retail disk on your other Mac, use it to boot the iMac with.

IMac 27" mid-2010 as a second screen

Hi,
I recently got a MacBook Pro Retina 13" (2015) and I would like to use my iMac 27" (mid-2010) as a second screen.
I already tried it by using a HDMI to Mini DisplayPort cable but it didn't work.
So I've checked on the Internet and as stated in this forum thread (Macbook pro 2014 connect to imac 27 2010), I need to use a Mini DisplayPort to Mini DisplayPort cable and since the Thunderbolt port on my MacBook Pro should handle it.
So I hope someone can confirm me this solution will work.
Thank you by advance.

It's correct.

IMac 27" (mid 2010): Will replacing the HD cause fan problems?

Hi,
I have an iMac 27" (mid 2010). My HD is broken, and I'd like to replace it. I've already installed an SSD, so replacing the HD shouldn't be much of a problem.
However I've read that replacing the HD causes the fan to spin up all the time. Some sites say this started one generation later, but some remain unspecific or say that this problem affects all iMacs. Before I replace my HD, I'd like to know what to expect.
So my question is: in my 2010 iMac, can I replace the HD without causing fan problems (provided I put the temp plug in the right place )?
Best regards,
F

OWC is mistaken. I don't know why they keep saying that. (I'm not even certain the OWC blog linked above related to using the same make drive on the late 2009s was ever correct. I had a long phone conversation with an upper level WD tech some time ago who said that the originals were special ordered by Apple.) Those drives have Apple proprietary firmware which puts the temp sensor output to the jumper block, and you cannot just replace with a drive of the same manufacturer. A non-Apple WD drive will not have that connection at the jumper block.
Two possibilities: Get an external stick-on temp sensor that will work with your model or use SSD Fan Control.
http://exirion.net/ssdfanctrl/
If I'm mistaken and you do get it to work directly with a replacement WD drive I will be pleasantly surprised, since I have a Late 2009 which will need a new drive sooner or later. Please post back with your results.

Is iMac 27" (mid 2010) Quad-Core Intel Core i7 64-bit kernel ???

Hello,
Sorry I'm not familiar with 64-bit term and would like to know is iMac 27" (mid 2010) Quad-Core Intel Core i7 a 64-bit processor and does it support in Mac OS X?? I'm confused as I from the Apple list "Mac OS X v10.6: Macs that use the 64-bit kernel" does not have latest iMac models. I plan to buy iMac 27" Core i7 for video editing and also like to know does Final Cut support 64-bit too. Appreciate all kind advise please.
Thanks in advance.

Hi,
it's in list...
These Macs *support the 64-bit kernel*, but do not use it by default.
*iMac (Early 2008) and later*
MacBook Pro (Early 2008) and later
The keyword is "not by default"

Macbook Pro (mid-2010) Won't Always Boot Following 10.9.4 Update (Error Images Included)

Two days ago I updated my mid-2010 Macbook Pro 13" to OS X 10.9.4 (from previous 10.9.3) and everything went fine as usual. However, yesterday, when I was turning off my laptop since I was out all day the system started behaving strangely. The "Shutdown" or "Restart" dialog's wouldn't do anything. I didn't think much of it at the time and simply held the power button down as I didn't have the time to play proverbial "20 questions" to figure out what was going on.
However, since then, my Mac has been unable to boot to OS X consistently. I tried to repair/verify the disk and permissions from the recovery partition, reset the SMC, and even utilized an old set of recovery tools I had running on a Snow Leopard external drive.
The list of everything I've tried:
Verifying the permissions through recovery which fails with error code 22 (an unknown error occurred) on every permission issue it found (only a few)
Verifying the disk which finds nothing wrong with it through recovery
Utilizing my Snow Leopard recovery tools HDD to just simply verify permissions and the disk. From the SL Recovery Tools HDD the Disk Utility was able to verify and repair any permission issues and as previously said, no disk issues were found
Tried re-installing OS X through Recovery which fails almost immediately due to unknown issues
Reset SMC
Tried "Safe Boot" by holding the Shift Key down
When I boot my Snow Leopard Recovery Tools HDD that I made and run through the verify/repair of disk utility I am able to restart the system and get into OS X Maverics for several reboots before the same errors (included in photos below) occur with 100% consistency.
This is how I was able to set verbose mode to see what was going on even though I haven't the slightest clue (I've never had a problem with OS X till today and I understand how Windows works far more than OS X - in fact I use OS X so I don't have to worry about things like this). Everything on the partition seems to still be in tact, the drive is working, but something is causing what's included in the screenshots to occur - and when these errors occur everything seems to get set into overdrive (the fan spins at max, the processor heats up, and the system in general warms up to what it feels like under very heavy load).

Thank you for your help in advanced.

Verifying a disk or permissions doesn't fix anything. They must be repaired. Then you will need to do a reinstall of OS X:
1. Restart the computer into the Recovery HD:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities 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.
2. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Install OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Upon completion you can reinstall the 10.9.4 update: OS X Mavericks 10.9.4 Update (Combo), if required.

My MacBook Pro 13in Mid-2010 won't start unless I hold the power button for about 10 seconds! Help Please!

Hello.
I have a MacBook Pro 13-inch (mid-2010):
Processor: 2.66GHz Intel Core 2 Duo
Memory: 4GB 1067 Mhz DDR3
Running Mac OS X 10.7.2
Yesterday I opened my computer (was sleeping as usual) and the screen just flasehed white and the computer powered off. The magnetic electricity thingy was connected and was green, so it was fully charged, and connected to the electricity.
Since it powered off, I tried turning it on again, and again, one second after starting to boot up, screen flashed white and the computer powered off.
I read somewhere I should hold down the power button longer, so I did, and it booted up. That's why I am able to write this. But every time I turn it off or put it to sleep, it does the same thing when I boot up.
If I don't hold the power button for 10 seconds or so, the computer won't work.
Then today, I did a backup of my entie hard drive, just in case. Later, I started using Excel, and about 1 hour after I was on it, suddenly it got really slow. Like I would click on a program like Safari, and it would take over 30-45 secs to start and be ready. And my computer is usually really fast!
I went on the Internet again, started in safe mode, boot up with option+command+P+R to reset PRAM, and nothing worked. Then suddenly on one turn-off/turn-on (since I can't restart because the computer only starts if I hold the power button for 10 seconds), again it is working at normal speed.
What can this be? Any ideas?
I really appreciate your time and help in advance
Gaby

Are you running the Apple-supplied RAM? Have you run Apple Hardware Test? I don't know what else you've tried, but this may be time to do a fresh install of Lion if you have not done so since installing Lion.

MacBook Pro Retina 15" mid-2012 won't boot in clamshell mode with an external display attached

I have a 15" MBPr mid-2012 running OS X 10.10.1. The system won't boot in clamshell mode (power is connected, lid shut) with an external display attached via an Apple Thunderbolt->DVI adapter. it boots fine if the lid is open. It isn't the adapter or the display since my 15" MBPr mid-2014 boots up just fine connected to the same adapter and monitor. And this system used to boot like this just fine some while ago (probably before it was upgraded to Yosemite). I've reset the NVRAM (twice) to no avail.
Has anyone encounter this? Anyone have a solution? Should I try an SMC reset (always a bit nervous about that)? Might it be a driver issue in Yosemite?
Thanks.

MacBook Pro (Mid 2010) will only boot in safe mode.

I've been unable to boot my MacBook Pro normally. It will boot in safe mode, and, until today, I was able to get a normal startup after resetting both PRAM and SMC. Running "Repair Disk" on the startup disk did not reveal any problems. I have also done a recovery boot to reinstall OS (10.9.1), which did not help either, though I did not wipe the hard disc first (I did back it up).
Had to take it to Apple back in January when the screen started acting funny, i.e. getting static-y and going blank for seconds at a time but then coming back. Their tests showed that there were no hardware problems, and the screen issue was eventually resolved by doing a PRAM reset. About 14 months ago, I had the logic board replaced.
Also, I'm not sure if this is related, but when I have been able to boot normally, if I quit Google Chrome, the machine will freeze completely.

Any ideas are much appreciated!

First try doing a Software Update.
Then restart and see if that works.
If not then I would update Java.
Restart and see if that works.
If not then delete the following plist items.
[invalid] com.oracle.java.Helper-Tool.plist
[invalid] com.oracle.java.Java-Updater.plist
Should find these in:
/Macintosh HD/Library/LaunchAgents
/Macintosh HD/Library/LaunchDaemons
Now restart & see if that works.
If that doesn't work try deleting everything in:
/Macintosh HD/Library/StartupItems
Hope this helps.

Windows 7 with bootcamp on Imac 27 mid-2010 impossible

I have purchased an IMAC 27 mod 2010 and I would like to install Windows 7 with Bootcamp.
I've tried everything from all sources infos. Impossible to install.
After last screen on windows install, when desktop is created for first user and last boot ... black screen with blinking cursor.
I've been able to run this install from VMWARE from OSX. I've tried to install last version of ATI driver, bootcamp 3.2 ... nothing work.
I'm totally lost from 2 weeks now.
I could I proceed to boot windows 7 on I IMAC ?
Please help

This is an old problem I once ran into, but it's completely unrelated to SP1 which is the purpose of this thread.
Here is the solution:

Mid 2010 Mac Pro boot camp recognizing 1.86GB RAM

I have a mid 2010 Mac Pro w/ 6GB RAM and a dedicated video card. Win7 32-bit is boot camped on it. I know 32-bit Windows can only use 3.75GB of RAM. However, this Mac Pro is only seeing 1.86GB.
Since this is Win7, no boot.ini is available for /3GB switch and editbcd /set increaseuserva 3072 did nothing, even after clearing out the variable and resetting it to 3072.
I came across a post saying UEFI/BIOS for Mac Pros cannot see more than 1.86GB RAM in a Windows 32-bit environment. Is this true? It was only the one post and I forgot where I saw it. If not, how do I resolve this issue? If not, that's fine. I can format and install Win7 64-bit if needed. I want to confirm 64-bit Win7 will recognize more than 1.86GB of RAM. Any input?
Thank you.

64 bit Windows will see and use all your ram.

Mac mini mid-2010 won't shut down

I have the server version of the Mac Mini mid-2010. It is running Mountain Lion (not server). When told to shut down from the Apple icon menu, it won't. The "round thing icon" just spins indefinitely. Can't do an EFI update, of course, because the computer won't shut off to do the update. There are no downloads available... it's up to date at 10.8.2
Ideas??

Make sure all work is saved and backed up; log off all other users if possible. Close all applications except for Terminal.
In Terminal, type
sudo shutdown -h now
Type in your password as requested. The computer should power off immediately.
Restart the computer in Safe mode, examine the console for logs to determine the cause of the problem.

My iMac 27" (mid-2010) won't boot up.
