Yosemite Upgrade - iMac mid-2011 - Stuck on white progress bar screen at about 50%
I have a mid 2011 iMac. I started the upgrade to Yosemite about 4 hours ago. For the last 3 and 1/2 hours it's been "stuck" at the white progress bar screen at about 50%. I hear the harddrive occasionally do reading/writing, but it isn't doing a lot just a tiny bit. I've seen others post across the net with similar situations, but no solutions. I'm willing to wait, but would love to know if it's actually proceeding or simply in some infinite loop.
Anyone know how to tell if it's in a loop or proceeding?
Anyone have any ideas on things to try?
I really don't want to try and interrupt the upgrade, but it doesn't appear it's going to complete.
Ideas?
Thanks for any help you all can provide.

This worked for my MBP 17" mid-2010 after 10 hours of minor panic watching progress bar stuck at 50%:
Reboot and hold SHIFT key to go into Safe Mode and keep holding that SHIFT key.
*Patience is the key to the Shift key*
Keep the Shift key down.
Do not let go of Shift key until you go to Italy when the computer does its Venetian blinds thing and goes into Safe Mode.
Check whether you have any login items. Do this via via Sys Preferences > Users & Groups
It is going to be slow. You are in SafeMode.
Remove any login apps.
Run any updates for Yosemite (e.g. Pages, Numbers, Keynote) within Safe Mode.
Reboot.
Remember, YMMV

I have just switched on my new 5s and gone through the intro sections. After entering my apple id, I selected the icloud update I wanted it to use (from my 4s). It is now stuck on the progress bar screen and has been for hours. Can I get it back to the original settings? I want to set it up as a new phone, until I can get on to a better wi-fi signal. Any help would be great.
Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,

Can't Install OSX Yosemite on iMac Mid-2009 Stuck - No Recovery Partition PLEASE HELP
I had an old iMac Mid-2009 2GB on OSX Lion, which had been kept away in the garage for a while. Pulled it out, ran Lion fine. It was going to be set up as a new computer, so I downloaded OSX Yosemite, planning to wipe and re-install after installation. Took a lot longer than I expected. After a while, the apple logo progress bar froze. I googled it and many people said just to wait it out, it could take up to 12 hours. 1 week later, still there. Fairly confident that nothing was going on on the hard drive. I reset the PRAM, didn't help. So I tried another fix I found which involved booting into the recovery partition. Guess what, no recovery partition . So finally I went to the trouble of creating an install usb. Booted fine, so I went into Disk Utility to erase my hard drive and re-install. But guess what, I couldn't! Can somebody please help! Or is this iMac stuffed?
Finally figured out the solution. My internal HDD appears to be not working after that faulty Yosemite installation. Just got a fast external HDD, plugged it into the iMac. Booted from the USB, went into Disk Utility and formatted it as Mac OS Extended (Journaled) in GUID. Installed and got up an running fine. Finally fixed this after 3 weeks! Hopefully this will help anyone that has the same problem.

Screen on my iMac mid 2011 goes white and I cannot continue
Hi the screen on my iMac mid 2011 goes white and I cannot continue. I tried doing a shut down and re-start, no luck
Work thru the setps at > Mac OS X: Gray screen appears during startup
Then if the problem is not fixed by the time you get down to the "Preform an Archive and Install of Mac OS X" section, go to > OS X: About OS X Recovery -
I have downloaded Yosemite from the App store and I attempted to upgrade from OS X 10.9.5. It is stuck on a white screen with a moveable mouse pointer but that is it. I can't get Command + L to work, so I can see any progress that is being made and I have tried to force boot it twice. Each time I force boot the machine I get a progress bar that goes about half way across and then just a blank white screen. I have read on some blogs that patience is the best procedure for this freeze but I have been waiting for almost 36 hours now and nothing is happening. One thing I want to mention is I have VMWare installed with a virtual machine of 300gigs, could this be the cause of the hangup? My 27inch IMAC is about 3 or 4 years old with a terabyte hard drive and 32gigs of ram. I have unplugged everything from the back except the network cable. Is about 36 hours reasonable for an upgrade? Is there a way to cut my losses and revert back to OS X 10.9.5?
When you start your notebook press F8 to enter Advanced boot options.
Is Repair my computer option available?
If yes choose it and press ENTER. Follow the menu on the screen and when you will see System recovery options try to use System Restore option.
Do you have some important data saved on your notebook?
If not install OS again using HDD recovery option and after 2 hours you will have clean preinstalled OS and everything will be OK again. -
Win 8 pro to win 8.1 pro on Imac mid 2011
Hi Community!
I'm experiencing the same issue as this thread https://discussions.apple.com/message/23429321#23429321
But it's on my Imac mid 2011.
I had windows 7, I upgraded with a windows 8 succesfully but when I want to update to 8.1 I have a black screen at the end of the installation (no lights) exactly like the computer is Off. When I reboot it restore to win 8
So I decided to restore windows 8 with a fresh install (all programs and files deleted) and bootcamp 5 installed before.
I have the same issue , I thought the problem was because of one of my drivers.
But even with a brand new Win8, with last update, The update 8.1 give me this **** black screen!!!
I tried with last AMD HD drivers in case it was the graphic drivers.
I really don't understand what happen!!
I have two sort of error code when It restore to win 8
0x1900101 - 40019 or 0x1900101 - 4000D
Does anyone have a successful update to win 8.1 with an Imac mid 2011?
I try to install with a complete win 8.1 DVD (no update) I will work?
thanks for your helpWell, I have finally figured "my" issue out. For me, it was the video driver for my 6970M adapter. The real kicker is that the driver provided by Microsoft during the windows installation which correctly identified my device was NOT compatible with 8.1 The driver provided by Bootcamp driver installation was NOT compatibile either.
Basically, you have to uninstall the display adapter and have "delete the driver" box checked in device manager. Leave it like that, do NOT reboot and install 8.1 The incompatible driver will put itself back on there again but, at least you'll be able to get into 8.1. You just have to uninstall that device again and go to AMD directly for the latest driver.
So, below is a more step by step of how I got my 8.1 passed the black screen issue.
I did a clean install of Windows 8.
During the installation process, select customize settings and turn OFF automatic windows updates AND turn OFF automatic driver updates.
Once at the desktop, uninstall the device AND device driver (display adapter). Do NOT reboot.
At this point I had to do windows updates to get 8.1 to show up in the windows store. However, if you have to do this, UNCHECK any driver related updates first. It will tell you to reboot, go ahead and do this. Once back at the desktop, go into device manager and make sure the display adapter is uninstalled/driver deleted or its at least the microsoft generic adapter. The point is to make sure no device specific adapter is installed.
Proceed to install 8.1. Let it go through its reboots and setup.
Once at the desktop of 8.1, go into device manager and see if the generic driver is there of it its a device specific driver, uninstall the device/driver, do not reboot.
Go to AMD (my display adapter maker) and get the latest drivers from them directly and make sure its for 8.1
Install that driver and reboot. It should work from there on out. You can then proceed to install other devices and bootcamp drivers.
This is what I had to do for my black screen problem. Its important to note that the black screen issue is common but being caused by a variety of issues. I was on the phone with Microsoft this morning and explained all of this and my steps that were taken. Its clear MS has a bad update package especially since 8.1 isn't playing well (causing black screen) with drivers that Windows itself installed during install. My fix may work for some, but not all. I hope it helps someone. -
Hi
My new Imac mid 2011 has no sound, Here are list of what I have done:
I have reinstalled the OS, but no luck
replaced the memory
ran the hard disk repair
checked the permission
done reset PRAM RESET
Sometimes the sounds comes after i restart the computer a few times, and the sound disapears again if the computer goes into sleep mode or after being idle for sometime, I also changed the settings to not let the Imac sleep but it still lose the sound.
By the way, during the start up if i hear the sound then sound works but many times only dvd driver spinns and no sound.
could be fault in the sound card or motherboard, i am actually new onto Mac world.

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.
The 5 second timing is important to a successful reset.
There is also a possibility the switch in the headphone jack is stuck. There is a tiny red light that you will see inside the jack if the switch is stuck on. -

Overheating Troubleshooting for 21.5 iMac (mid 2011)?
I have been having issues lately with my 21.5" iMac (mid 2011). It was purchased in June 2011 and is currently running the latest version of OS X.
This issue I am having is that once the computer has been is use for a few minutes (usually around 5-10...depending on usage type), the computer will freeze up and make clicking noises and is very warm to the touch. Specifically, I will be unable to do anything and the cursor will pinwheel. I can usually move the cursor around, but cannot click anything. During the "freeze", there are clicking noises. The clicking is in groups of twos....like Click...Click.....pause for a few seconds, Click.....Click, etc.... The noise sounds like it is coming from around the center bottom of the computer...maybe near or around where the base connects. It sounds like it may be a drive starting and stopping, or a fan stopping and starting....I don't know?....it's a mechanical type clicking it seems. It will freeze for extended periods of time (minutes) then you can usually do something else, but it will just happen again. Sometimes, you have to shut the computer down and when you do it takes forever to boot back up.
Any ideas on what may be causing this or what I can do to troubleshoot the cause? I'm too far away from an Apple Store to just casually take it in to have it looked at.
Thanks.It sounds very likely that the hard drive will require replacement. If you're not comfortable doing the removal and replacement, you'll just have to take it to an Apple authorized service provider to have the drive replaced.
As noted in the tutorial link Old Toad provided, OEM Apple hard drives for the iMac have an internal temperature sensor that is not present in non-OEM Apple models. If you use a non-OEM Apple drive, with the original Apple cable, it's very likely the fans will run at high speed 6000 rpm once the system warms up after power-on.
Replacing a mid-2011 iMac hard drive even WITH a proper sensor cable still requires a few tools and some significant disassembly, including the removal and temporary storage of the LED screen in a relatively dust-free environment, and disconnecting a number of cables in order to replace the drive before subsequent re-assembly.
Other World Computing (www.macsales.com) offers (both hard drives and) a hard drive cable with a thermal sensor that mimics the function of the sensor present in the OEM Apple hard drives. OWC updated both the cable and their original YouTube video for mid-2011 iMac 21.5" hard drive replacement in March 2014: http://www.youtube.com/watch?v=rLuk_8w7KwU
The OWC replacement cable allows you to select most any 3.5" hard drive and still have proper 'factory' fan operation, so the fans aren't racing at full speed all the time.
The full OWC toolkit complete with sensor cable is here: http://eshop.macsales.com/item/OWC/DIYIMACHDD11/
The OWC sensor cable only is here: http://eshop.macsales.com/item/OWC/DIDIMACHDD11/
Then you still need to select and purchase a 3.5" internal hard drive.
I've used OWC for a number of upgrades to the three Macs in our family: mid-2007 MacBook, mid-2009 Unibody MacBook Pro, and mid-2011 iMac. I'm planning to do a hard-drive upgrade to my mid-2011 iMac using the OWC cable, once the AppleCare warranty expires. -
How do I get my iPhoto library from a ppc g5 to an intel iMac mid 2011
How do I get my Iphoto library from a ppc g5 to an intel imac mid 2011?
I recommend tha tyou do not use migration assistant - it has a poor record of moving the iPhoto library successfully
Connect the two Macs together (network, firewire target mode, etc) or use an external hard drive formed Mac OS extended (journaled) and drag the iPhoto library intact as a single entity from the old Mac to the pictures folder of the new Mac - launch iPhoto on the new mac and it will open the library and convert it as needed and you will be ready move forward.

Why doesn't the new ram memory for iMac (mid 2011) work (different brand)?
Hello,
I have an Macbook pro at home (early 2011) and an iMac (mid 2011).
My macbook pro had 2 x 2GB ram and I wanted it to be higher, zo I bought 2 x 4GB ram from Kingston. I installed it succesfully in the macbook pro.
I saw that the ram in my macbook and iMac where the same type (1333MHz DDR3), so I figured the Ram-modules were interchangable. The iMac has 2 x 4GB ram put in by Apple itself. It's a weird brand name, something Asian that I hadn't heard off.
I thought I could put the original ones from my macbook pro (brand Samsung) in with the original ones that where already in the iMac.
So the slots would look like:
4GB 4GB -> already in iMac, original modules with brand name I can't remember ;-).
2GB 2GB -> original modules from macbook pro Samsung
I also put in in like shown: the same types next to eachother.
Then I turned my iMac on and it only "beeped".
So I tried to put it in different combinations (4GB next to 2GB etc etc). But it still "beeped".
Very frustrating... because I thought I was doing a good thing by buying Kingston (quite expensive also...).
Now I think I had better purchased new 2 x 4GB Samsung and combined that with the 2 x 2GB Samsung from the macbook and put it all in the iMac. And take those of the iMac (2 x 4GB Asian brand) and put those in the macbook... This way it were all the same brands combined...
But I did by Kingston... so... why can't I combine the original iMac ram modules with the Samung modules from the macbook????? I've read that in older iMac models, the slots are sensitive for different brands, but couldn't find out for sure for my iMac (mid 2011). It's a bit stupid, no... Both mac's are from 2011 and have the same specifications...
Could anyone give me an answer?
A little bit mad at Mac right now ;-).
Thanks in advance!

PS: if it is about the OSX I'm using... can't update to Maverick for software licence reasons... I need the iMac for work a lot...Hello,
I'm sorry if it wasn't clear... but I don't have ram issues with the Kingston type...
I used the new Kinsgtons in my macbook and wanted to take the originals from the macbook (Samsung) and them put in my iMac next to the other modules that were already in the iMac.
I know it's a bit confusing... ;-)
So... I have 2 x 4gb in my iMac from a brand I can't remember the name off... And I also wanted to put in 2 x 2 GB Samsung modules. So that would count up to 12 GB ram. Why? Because I took the Samsung modules out of my macbook and I thought I could reuse them in my iMac since they have the same specifications (1333MHz DDR3). But My iMac won't start up as soon as I insert those 2 Samsung modules. -
I bought a new mac including 10.8 Mountain Lion. (How) can I now install 10.8 on my older iMac (mid-2011) which came with 10.6?
You will need to buy it at the app store. The license for the pre-installed OS on your new machine is only for that machine. Only OS's purchased from the app store can be installed on more than one machine (as long as you own it).

Software Update is not finding latest release (April 3) of Java 2012 001 Update on my iMac mid-2007, but it downloaded it automatically on my iMac mid-2011 yesterday. Both are running Mac OS X Lion 10.7.3. When I try to download the update manually from Apple on my older iMac, it downloads okay, but when I try to open the dmg file, I get a warning message saying that opening this update may make your computer LESS secure. Do you want to proceed? (I did not).
Why would Software Update find this update and install it automatically on one iMac and not the other, if they are both running the same version of Mac OS X Lion? I checked the installed software list on my old iMac and the Java update does not appear there. Why would this update make my old iMac less secure?Recall that Java is not installed as part of Lion.
You have to install it (and are asked if you want to) when you first try to run some java stuff.
Is it possible that the iMac 2007 does not have Java yet?
Try this: open Terminal (from Utilities) and type java -version (exactly like that, with the space before the hyphen).
What do you get?
Consistent with this theory is that the dmg thing gave you the warning - installing java might make your machine less secure because java is a means for bad guys to try to do bad things to your computer.

After the last up date for Safari (Mac OS X 10.8.5 in a iMac mid 2011 21.5 inch 2.8GHz Intel Core i7)
The window don't open or they are there and only in an outline, kind of like they're behind the screen.
I have also done a system update and then a system reinstall.
