Boot Rom/BIOS emulation issue with latest iMacs?

Hi,
Firstly thanks for viewing.
We've just bought 34 new iMac's and previously had (and still have) 60 odd Aluminum iMac's dual booting OS X/Windows which have no problems.
The new iMacs though seem to be having huge issues with booting Window's the first 2 attempts wether using Apple's Startup Manager or rEFIt.
The first attempt the machine will just hang after at a grey screen after volume selection and the second attempt you will receive a "Disk Read Error" and the third attempt the machine will boot normally and this behavior is happening on all of the brand new 34 iMac's.
rEFIt produces the following error:
Error: Not found return from legacy loader;
Error: not found from locatedevicepath;
Error: not found from locatedevicepath;
Error: load error while (re)opening our installation volume;
Which leads me to believe the issue lies with Apple's Boot Rom and the hand over between EFI and BIOS emulation.
I have tried multiple installs of OS X Snow Leopard with 32 bit XP, 32 bit Vista and & 32 bit Windows 7 as well as using Bootcamp 3.1 which really only add's driver support for Windows 7 no Boot Rom updates.
If anyone is having similar issue's I'd love to hear and any work arounds you may have.
Thanks for taking the time to read my post.

Hi Sea Dog,
Thanks for your reply . But I cannot find anything related to my problem in the link you attached (or it’s “sublinks”). One sublink is about an annoying usb3 bug with some problem related to the S3 sleep state. (Maybe this is the one you are referring to?) But I do not have this problem, I can wake my PC from the S3 sleep state via my connected USB devices. The problem I have is that I also start my PC after a shutdown (=S5 state I assume) via my connected USB devices, which I do not want to happen since too easy to start the PC accidently for example by just moving the mouse a little bit. As I write above, I think this is caused by MSI:s choice to configure their BIOS regarding “Resume from S3/S4/S5 by USB Device”. If I am right about the cause to my problem, I guess MSI should have chosen this resume option without the "…S4/S5…" or at least without the "S5" (By the way, I seem to have version C2 of the Z87 chipset if I understand a note correct on the MB box.)
Again, am I correct about my idea to the cause of this problem?? Can someone please advise how to solve it if possible??

Take each of the following steps that you haven't already tried.
1. If you've recently plugged anything into the audio-out (headphone) port, plug and unplug it a couple of times.
2. From the menu bar, select
 ▹ System Preferences ▹ Sound ▹ Output
Check the settings. The internal speakers should be selected as the output device, the Mute box should not be checked, and the volume slider should be at least halfway to the right.
3. Look inside the headphone port. If a red light is coming from the port, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a headphone mini-stereo jack of the proper size.Inserting any kind of tool in the port may cause damage that won't be covered by your warranty.
4. Boot in safe mode by holding down the shift key at the startup chime. It will take much longer than usual. You don't have to log in; just reboot as usual (without holding any keys) when the login screen appears. (Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.)
5. Reset the NVRAM.
6. Reset the SMC.
7. Reinstall OS X after backing up all data as a precaution. You won't need your backup unless something goes wrong.
8. Make a "Genius" appointment at an Apple Store.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to bare metal from any of them.) Don’t erase the recovery partition, if present.
*An SSD doesn't need to be zeroed.

Wake issues with 24" iMac

I am having the issue with my iMac lab. Units will go to sleep and when a student tries to use the unit there is no response from keyboard but mouse will respond. They need to be restarted to resolve the issue but should it go to sleep again we start the process all over. I have 17 in this lab and have been sending them in for repair two at a time. They replaced the DC/SATA cable on the first two and it resolved nothing. Resetting PRAM and PMU also did not correct the issue.
Any ideas? Hardware? Software?

I have a computer lab with 25 with the same problem. I found this happened after they keyboard update. Has anyone really solved this problem with the keyboards not responding after the computers go to sleep? We have to restart several every day, every hour. What is apple doing with this?

IMac isn't loading a specific website (can't connect to that server), regardless of browser, though the same website will load on other computers on same network. Is it an issue with the iMac's settings?

Our iMac isn't loading a specific website (we get a message saying it can't connect to that specific server), regardless of browser (I've tried it in Chrome, Safari, and Firefox). However, the same website, which is for a major medical provider, loads without any issue on our other computers on the same wireless network. Is it an issue with the iMac's settings? All other websites seem to be loading without issue on the iMac.

... Is it an issue with the iMac's settings?
Possibly. Make sure you are not using a proxy server. Look in Safari Preferences > Advanced > Proxies > "Change Settings..." This will take you to the applicable Network Preferences. Make sure that nothing is selected in the "select a protocol to configure" list. It should look like this:
Still not working?
Locate your Terminal app. It is in your Utilities folder. Open Terminal.
In Terminal, copy (triple-click) and paste the following line:
osascript -e 'tell application "System Events" to get name of every login item'
This will produce a list of all your account login items.
While you are in Terminal, copy (triple-click) and paste the following line:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'
This will produce a list of all non-Apple kernel extensions. There will be few, if any.
Post the results of the above.

Weird issues with latest X-Fi Driver/Software

-Weird issues with latest X-Fi Driver/SoftwareO So I decided to update my X-fi drivers and software today, but I am running into some issues.
First and foremost is that my Volume Panel no longer works correctly. It brings up this cheap pos window when I click on the Systray icon instead of the corrrect full featured interface.
It lists the merdia source programs and has a volume dial, thats all this new one has.
The other issues are that none of the software updates want to install: Alchemy, Mixer, Mediasource Go
They all give me a message after I being to install that says "can not locate layout.bin please specify the path"? and gives my a "this setip reqires a cd" window and lists a path to a temp folder inside my windows folder.
Installing these for Vista? Ultimate 32-bit.

X99S GAMING 9 AC Not booting - Debug 94 code - Issue with GTX 980 SLI in WoW

Hello, I bought the X99S GAMING 9 AC motherboard but have ran into some issues.
The computer won't boot when I put my second MSI GTX 980 Gaming 4 GB card in the last PCEI 3.0 port (PCIE port 5) and I get the debug LED message 94 on the motherboard. I have a SLI setup.
The first card I have in the second PCIE 3.0 port due to the Noctua U14S CPU fan takes up space for the first slot. So I have been running my grafic cards in PCIE slot 2 and 4 with some issues.
First the card in slot 2 gets really warm over 86 celsius. And second: SLI runs really poorly in World of Warcraft. I get a lot higher performance with just one card activated. I am not sure if it's cause I am not running my cards in the recommended PCIE 3.0 ports or because WoW has some issues with SLI, but I heard other people have no issues at all with WoW in SLI.
I got the same issue with 3Dmark firestrike, the cards perform really poor in SLI. I get higher score with SLI turned off..
Though SLI seems to run pretty well in 3dmark 11 and Diablo 3 Reaper of Souls.
But the main issue right now, is that the computer won't boot with the grafic cards in PCIE port 2 and 5. The solution to run them next to each other is not good, cause it gets really hot and I get bad performance in WoW and Firestrike.
Picture of my setup before I switched places with the grafic cards as you can see, it is really tight:
Any upcoming bios updates (got v1.3) that will solve this issue on the horization? Hopefully this get sorted out really soon..
My whole computer setup:
Intel i7 5820K | MSI X99S Gaming 9 AC (bios 1.3) | SLI MSI GTX 980 Gaming 4GB | Samsung 850 Pro 512 GB | WD Red 4TB | G.Skill Ripjaws DDR4 3000MHz 4x4GB | EVGA SuperNOVA P2 1000W | Noctua NH-U14S PnP | Fractal Design Define XL R2 | 5 Noctua NF-A14 PWM 140mm fans | Windows 7 Pro 64 bit

You must use the recommended PCIE slots as the manual says for your CPU type, PCIE #1 and PCIE #4 if I remember, just open the manual :P for optimal 2Way SLI, also your 5820k will limit to 28 pcie lanes only if you plan to add more vgas...the other problem is your giant CPU air cooler blocking PCIE#1, do a favor to yourself, buy a watercooler for your 5820k and your problems are gone, add some overclock in your system, low noise and better temps.
Here I use 3x980 in SLI with X99S Gaming 9 AC, going soon to WC the VGAs with EK blocks.....3way is far more temperature critical than 2way spaced one.
Cheers

Complicated Issues With Intel iMac

So here we go:
Recently, after updating my QuickTime I restarted my iMac to a continuous "setup assistant" loop which from further research I came to find out that I wasn't the only one with this issue. So my solution to that was to go to the Apple Store and get an erase and install because I couldn't boot from my disk when the computer would start up.
Currently, my computer is hit or miss on startup. Sometimes it goes into the system like butter and times like today my computer LITERALLY takes 10-15 minutes to load fully. Upon load the computer functions at a fine speed but I don't understand why it would take this long to load the system. I do have an external HDD to use with Time Machine and often thought that that would be the problem on startup (getting confused about the startup disk or something) so I typically unplug it before startup and it still takes 10-15 minutes to reach my desktop. In addition, after the erase and install it never goes to the loading Leopard screen with the blue bar that goes around the screen right before you get to your desktop image.
Several things about this made me feel like resetting the PRAM was a good idea, however, whenever I restart the computer hold down OptionCTRL+PR it's like my computer ignores that. I do it right when the computer turns on and before the gray screen like the document says and the computer just skips it altogether and goes to the apple with the loading wheel. I have no clue what's wrong with my computer and wish it would function like the day before I updated QuickTime!
Any help?

Use the Command key, not the Control key to reset PRAM (Cmd-Opt-P-R).
That said, it appears you have no data on the new iMac to save, so why not proceed with a clean installation? Turn off your iMac, take the gray Installation DVD that came with your iMac and insert it in the DVD slot on the right side of your display case. Hold down the C key while pressing the power button, and let it startup from the DVD. Select English as your language, then select the Erase and Install option, and let the default configuration setup proceed. After about 45 minutes (unless you elected to let it install all the available foreign languages (Options button during setup phase)), it will finish and reboot your Mac.
After restart, answer the questions so it can setup your user account and connect you to the Internet for registration and software updates. You may want to proceed with the Install Bundled Software package on the Installation DVD at this point to get the iLife '08 suite installed, as well.
It would probably be wise to use Disk Utility (Applications/Utilities) to erase your Time Machine external FireWire HD so it can start with a clean drive, as well. You don't want to save the damaged stuff that's surely on that drive if you used it for Time Machine previously. Then, go into System Preferences/Time Machine and select the erased FireWire drive to use it.

Graphic Issues with Leopard - iMac 24" White GeForce 7300 GT

Upon installing Leopard, I've noticed several graphics issues and general lag and delayed response with the interface. I'm running a 24" iMac 2.16ghz White early 2007, 3gb of RAM, with the GeForce 7300GT card. I have Time Machine disabled, and Spotlight has fully indexed.
When installing Leopard, I did an "Erase and Install" and have manually installed my Applications after the Leopard install. I'm using only a few applications that are all "Leopard ready" and have a relatively clean system at this point. I have also cleaned the PRAM, per the recommendations in some of the threads ive read, which didn't seem to correct the issue in this case.
It seems that any time I run any type of video or graphical application, such as Photo Booth, World of Warcraft, iChat, etc, I get a large amount of lag and slow response with the interface. Windows respond very slowly, and the applications freeze for 15-20 seconds. Even when not engaging any applications, opening folders in the finder as well as the dock appear to stall and respond very slowly.
Aside from these issues, Leopard has performed very well and I have had no other issues. Quicklook and coverflow all seem to respond very quickly and smoothly. My guess is that it may be driver related as it seems to be centered around items that are engaging the video card, though it is strange how some graphical effects seem to work smoothly while others are rather choppy. I have been watching the Activity Monitor and there don't appear to be any processes that are sucking up CPU, and nothing obvious that may be reducing performance.
I'm just curious if anyone else has noticed anything similar to this on similar hardware, or possibly may know what the culprit could be. My best guess, again, is that it could be the drivers or firmware with this specific hardware that I'm using.
Thanks for your time

I've had the same graphics issues with my white iMac 24 (serial no starts W8638), but with the GeForce 7600 card. AppleCare got me to do all the usual stuff (reset PRAM, clean Leopard install etc) but problems continued. The usual pattern is that after a while horizontal lines appear (usually in Safari) and things deteriorate form then on until there is so much pixellation that I have to turn off and back on.
Yesterday I ran for several hours using SMCFanControl to set the fans to max and had no problems, so my suspicion is that the additional graphics requirements of Leopard are over-heating the graphics card or logic board.
The Apple engineer took the machine away today and said they'll probably replace the logic board and graphics card (I think they can't change one without the other in the iMac?).
Will be a few days but I'll report back on what repairs they make and whether they solve the problem. My fear is that any changes they make will have no effect if its a design problem and the card is just not up to the job without over-heating. Though it could be the card just needs a good clean
Has anyone else tried increasing fan speed?

Ical syncing issues with iphone/imac after lion OS update.

Hi All,
I upgraded to lion and now have two issues with syncing my iphone and ipad to my imac.
First issue is that calander entries created on the iphone/ipad do not appear in the imac calander after syncing.
Second issue is that if I change an calander entry on my imac, the old entry and the new entry will show up on my iphone. For example. I created an event and accidently clicked out of it before changing the name. I then reopened that entry and changed the name and date. In my imac ical calender I only had one entry at the final date with the correct name. When I synced my iphone and ipad however two events showed up on the iphone and ipad. The original "new event", and the event with the correct name and date.
The same thing happened when I had the same event occuring for 5 days, I manual copied the one event five times on the one day and then dragged them to the correct days in ical on my imac. When I synced my iphone I had both the 5 entries on the one day, as well as the entries on the days I had dragged them to.
In summary, now when I look at my calander in ical on my imac it looks great, but on my iphone it has all these extra entries. It is as though when it syncs it shows me all of my previous entries and changes, instead of the actual current calander.
Any thoughts how I can get the imac and iphone icals to look the same?
and in case you were wondering, I dont use Icloud. I did set it up and turned it off after the duplicate entry problem that everyone has mentioned. I dont have that duplicate entry issue anymore.
Thanks
Adrian

From what your write, it is a little hard to tell, what exactly your problem is, though you may want to try the following, which helped me at time:
step one:
export all of your calendars one by one, including the one with entries giving you problems
step two:
erase all of your calendars and create a dummy character, check if syncing works with that one.
reimport the previously exported calendars one by one, redoing the syncing routines.
In the instances I had problems, I found that exporting and reimporting a calendar file usually did away with the problem
Also, at least on my machines, turning on the birthday link to address book, created some problems, so you might want to try without that feature too.
If you got everything working on one machine, another strategy can be to reinitiate syncing from that one, i.e. erase and reinstall the syncing process on the others. Just make sure you have an up to date back up of your entries.

Sleep Issues with g5 Imac

I have a g5 iMac running OsX Panther. 1.6 Ghz with 256 Ram.
Anyways, the computer randomly and frequently goes to sleep. The hot corners are not set for that, infact in the settings i've set it to never go to sleep. Some days, like in the last hour, the computer will go to sleep, i wake it up, and within a minute, it goes back to sleep. Some days it wont go to sleep at all. The problem seems to be truely random. The only programs running are Entourage, Safari and Adium, sometimes Itunes and Filemaker.
Has anyone heard of a problem like this before? Any tips or trouble shooting ideas?
Thanks.

First read Apple doc.#25801 on sleep settings.
A number of sleep-related issues can appear after incremental Mac OSX updates, including the inability to properly go to sleep, problems waking from sleep, and having your display go to sleep without your Mac going to sleep. The most common culprit is Bluetooth. Try these tips to fix your sleep problems.
WAKE UP
In System Preferences>Bluetooth, uncheck Allow Bluetooth Devices To Wake This Computer. If you are using a Bluetooth mouse and keyboard, you'll have to wake your Mac by pressing the power button.
FILE CORRUPTION
Your Bluetooth preference file may be corrupt-you'll need to delete it. Turn Bluetooth off, then go to the /Users/user name/Library/Preferences folder. Look for a file called com.apple.Bluetooth.plist and trash it.The OS will create a new preference file when you enable Bluetooth again.
ENERGY SAVER
If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:
-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--(username is your name or System Administrators name).
-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.
Some, in these forums, have had luck fixing sleep issues downloading the Combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
Yours could be the 10.3.9 Combo update (you did'nt say what version you are using). Others reading, download the combo update that applies to you!
Cheers!

SERIOUS lag issues with Intel iMac

Hello everyone,
I'm pretty frustrated right now. I've been having this serious lag issue with my new iMac for the past few days. I think it may have started after I ran the last security update.
What happens:
When switching between apps, the system will hang for 1-3 seconds between doing anything. This includes typing, mouse requests, etc. It's VERY frustrating. I have activity monitor open currently, and I am seeing both Safari and SystemUIServer hogging up the CPU resources like CRAZY. I've even seen Safari recently give a CPU usage of 120%, right before I loaded this webpage. tis isn't just centralized to Safari too.... I have the following apps running:
Adium 0.89.1
FoireFox 1.5.0.8
Safari
Activity Monitor
My Memory stats currently are:
175MB Wired
708MB Active
618MB Inactive
1.47GB Used
There should be no reason I'm getting these lags with just two web browsers and a chat client open.
Has anyone else expierenced the lags?? Any suggestions? I'm almost ready to reinstall OS X and not run the last security update. Thanks

Hello Matthew
Are you running any maintenance scripts on a regular basis?
http://www.thexlab.com/faqs/maintscripts.html
I would manually run this script from The X Lab, and my load times would improve greatly. The problem was, I would forget to run them untill I noticed web pages loading slow or iTunes and iPhoto taking for ever. It wasn't untill someone here in discussions suggested Anacron that I saw the light. WOW what a difference Anacron has been making in my overall system speed. My iMac has not been shutdown for 11days 5hrs 34mins (sleep or use only) and opening new App's, switching App's and web pages load as fast or faster than after a fresh start up. If your system is operating properly and you are having only what seems to be a slow or sluggish issue Anacron will make a difference.

Is anyone having issues with 27inch iMac late 2012 locking up when processing photos?

Purchased new IMac 27 in July 2013 and 15 Macbook Air in November. I upgraded all my software at the time of the Air purchase. This is my 3rd Mac book and second IMac. Have all the same software on each. The IMac keeps locking up especially when I am processing in Aperture. It is worse when trying to move between Aperture and Elements or Big Aperture. I have not had an issue with Air even when useing same file on same soruce.
I took the IMac to shop for color bleed in moniter and then kept it a week, tested it, replaced the monitor, but said system is fine.
Any one else having an issue. is it my PC or an issue with the software/Maverick.

Got a late 2013 iMac 27". No problem at all. Try going to Disk Utility (in applications>utilities) and repair permissions. And then borrow a copy of Disk Warrior and clean optimize your hard drive.
Within Aperture yourself, do you know how to restore/repair your library? Hold down the apple & option keys and simultaneously start Aperture. You will be prompted on screen. That usually fixes hangups. I do it monthly.

Performance issues with latest iTunes update

Hello everyone,
I'm having somewhat of an issue with the latest update for iTunes (10.5), ever since the update was installed the 'AppleMobileDeviceService.exe' is using all my processing power.
Now I know my laptop isn't the latest spec, but before this was never an issue. The only way I can still work with it is when I turn off the service via the Task Manager.
When I launch the iTunes programme it gets even worse, another service called 'APSdeamon.exe' is eating up the processor aswell, albeit they both consume 50% now. As a result I cannot access the iTunes Store or do much else.
I do have to mention all my music is stored on an external HDD which is connected via USB to my laptop, but this was never any different.
I've reïnstalled all Apple components twice already, one including a specific deletion of all Apple program folders manually.
Since I can always turn off the services manually it isn't a big issue, but does anyone have any suggestions or ideas how this could be resolved?

Hello Mauricio,
Thank you for the details of the issue you are experiencing with installing the latest iTunes update. I recommend following the steps below:
Resolution
Follow these steps to resolve the issue:
Check for .dll files
Go to C:\Program Files (x86)\iTunes and C:\Program Files\iTunes and look for .dll files.

Reboot your computer.
Note: Depending on your operating system, you may only have one of the listed paths.
Uninstall and reinstall iTunes
Uninstall iTunes and all of its related components.
Reboot your computer. If you can't uninstall a piece of Apple software, try using the Microsoft Program Install and Uninstall Utility.
