Mac mini freezing with squares on the screen
I have a mid 2011 mac mini which recently started freezing fairly regularly. It will make a static noise and the screen will show a lot of squares which is odd. It has 3rd party ram, but the issue is reproducable with the standard ram.
Here is the log (I think). Any help wouyld be appreciated as it is preventing me from doing some important work:

Hmmm, with the static noise... could you have develop a Ground Loop somewhere, or in some Peripheral?

Mid 2011 Mac MIni Freezing with OSX 10.8.2
My Mid 2011 Mac Mini running OS X 10.8.2 has been Freezing (The baloon spins often) over random things. Is there a scan I can do to check problems. This is my first experience with a Mac and thought they weren't supposed to freeze. I run a few programs at a time but I do have 8g of ram with 2.3 GHz Intel Core i5.
The next time you have the problem, note the exact times when it starts and ends: hour, minute, second.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Scroll back in the log to the time you noted above. Post any messages timestamped during that interval – the text, please, not a screenshot.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into a message.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting. -
T540p freezes with bars across the screen
I have a T540p with Win7 ultimate. It occurres randomly that all of the sudden it freezes and I get horizontal rectangles all accross the screen. Also on the speakers I get a 0.5sec loop noise.
The only way to get it back in order is to do a hard reboot (press the power button until it switches off).
Does anyone experience the same and even better - has a solution to that?
Best regards,

Mac mini freezes at startup showing the apple and spinning gear
Went through a software update and it prompted me to restart the computer and it has been frozen ever since on the same startup screen
Assuming you're running either Lion or Mountain Lion, restart using the Command+R keys which should boot you into the Recovery HD. From there, go into DIsk Utilities and Verify the disk. If there any errors, run the Repair. You may also want to Verify/Repair permissions while you're in there.

My Mac Mini won't get past the initial startup screen with the Apple logo. What can I do?
After a long distance move, my Mac Mini won't startup past the logo screen. What can I do?
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, boot from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. -
Issues with lines across the screen, as well as freezing
Issues with lines across the screen, as well as freezing
Hello all
Got an iMac since January 2008 and I do like it a lot, even though it has some issues:
-- It displays (quite often) lines partially across the screen
-- Lines appear as well when opening applications or when menus come up
-- The system freezes more than I like to admit (more than my Windows/Ubuntu box)
I don't know if the freezing has to do with the lines that are shown on my screen. But I assume that both issues relate to some video card problem. I can't be sure - but that's what I assume from living with this issue day to day.
The line on the desktop (most of the time it is there before login) I can always get rid of by changing the display resolution to something else and then changing it back. Normally the line is gone, or, reappears on a different spot on the desktop. But repeating the procedure removes the line.
However, this does not mean that the lines are not showing up again when launching apps or displaying menus!
And since those lines appear to happen randomly, I think it's safe to assume that we're not talking dead pixels here, either...
About the freezing:
My iMac freezes sometimes when I move the mouse around, when switching desktops using "spaces" or when the zoom function of the Dock kicks in. Sometimes the screen goes completely black, sometimes completely white. The mouse, however, always works. But the system requires a reboot.
Again, this happens too often to feel comfy about it.
With my little knowledge of Mac troubleshooting I assume that there's something wrong with the ATI card that's built into my Mac. On the other hand, some people say that they started getting similar issues after updating their OS to Leopard. Again other people say that such issues stem from an ATI revision that is too old and the Mac should get a new ATI card. And how would that work? Isn't that an "all-in-one" machine with everything soldered onto the mainboard?
So, any help in this matter is greatly appreciated...
Cheers,
RainerHere are a few screen photos I've taken (not screenshots, as the lines are not visible when taking screenshots. I used my digicam to snap those...).
Here's the link to those screen photos displaying some of the many lines I keep having:

MAC MINI BLOCKED AND PASS OUT THE OPENING SESSION SCREEN
Hi, i hope someone can help me.
(i'm a french user, so i'll try to write a good english)
I've a mac MINI (2006) Intel Core Solo
Mac OSX 10.4.11 Tiger
I've no problem since some days.
I'm not the usual user.
Is the problem description :
• I start my Mac mini by pressing the button.
• "dong"
• I see the apple on the screen with spiral progression, all right.
• after around 15 sec. normally, at this moment, the opening session screen must appear… (there are 2 users, one administrator [with password] and one guest without password) but it don't.
• After a brief flash between two different screens (blue-gray),
the gray screen with the apple and the spiral progression re-appear but BLOCKED.
• There are some pixels lost in disorder at the top-left of the screen (the place of the starting mouse-arrow).
• After some minutes, or when i click away (i really don't now exactly when…)
The session of the guest starting normally (with some slownesses)
• I've a AirPort connexion with an iMac (Leopard 10.5.5).
• I've noted that someday, my usual network connexion have been changed (on the mac mini only), and my Mini tryed to connect with the connection of a neighbor.
As if this connexion have been selected by default.
•• I've tryed to restart, close the session etc.
•• I've lunched the disc utility to verify the HD…
•• And finally, I've passed out the problem with changing the account parameters :
Open the session automaticaly as a guest. Passed out but not resolved !!
••• THE PROBLEM STILL HERE, but for a few seconds only
(blocking lasts only two seconds).
So, can someone help me ?
What type of problem can it be ?
I hope someone has allready resolved it !
Thanks for reading.Hi you, i love your post…
So, i suggest you :
- In the account parameters (in préf. sys.)
- Delete the guest account created.
- Specify start automatically as "your Admin. name"
- Restart your computer.
- Go one more time in the Account param. pane
- Create a new guest account and modify some settings (such as display of the file for users in opening session screen etc.)
- Specify automatic start with guest
- Restart you Mac Mini.
Of course you have note that i've solved (for the moment only ?) the problem.
But i must say it for others, if someone has the same pb.
When my Mac Mini was Blocked, in fact, the computer seems all right but the display not. As the opening session screen was behind this static grey-apple-screen.
In addition, i've forgotten that there is an other screen with
"Démarrage de Mac OS X en cours…"
So, when i've unplugged my screen during the blocked screen,
and re-plugged it, all returns right : i can see my opening session screen…
So, if some one can tell me what is the problem exactly…
I'm curious.
So, at this moment, i've started my Mini once time only.
I hope all stay right in future…
Thanks so munch to me for my response.

Mac mini freezes and then screen fragments
Our Mac Mini freezes up constantly. Some days it happens after a few minutes of running and other times after a few hors. After the computer freezes, the screen fragments. We seem to have enough memory and so not certain what the problem could be.
AKSHi AKS,
Maybe you have got a temperature problem affected Mac Mini as our Mac Mini Server. You can read about it here:
https://discussions.apple.com/message/13242219#13242219
Such problems sometimes gets worse by time so I suggest you should run the EFI test and then contact Apple service before running out of guarantee.
Good luck!

Podcasts from Current Tv, since three weeks prior to the Nov 2012 election have had a url problem and cannot be played on my mac mini 2011 with 10.8.2 and the latest Itunes? anyone know why> ? I am in contact with Itunes now and they wanted screenshots of the problem, I can get these current tv episodes with a vpn and my isp says they are not blocking them, but i was surprised that prior to the election they were blocked, ?
I also can get them on my Android Samsung Galaxy note 2 with no problem but on the Macmini cannot>/? I Unsubscribed and subscribed many times but still no luck, any ideas? I am waiting for the senior advisor to get back to me on this issue. I am in THailand now where the problem is happening and as I said the ISP says they do not block any podcasts.I also do not want it on my iphone 5, so I have to wait and see why the mac mini is not getting it.I seem to have fixed it by putting <div class="clearfloat"></div> after the navigation bar?

I just purchased the Mac Mini Server with the intention of replacing Lion Server with Lion for the first hard drive while installing Windows 7 thru Bootcamp on the second hard drive. Is it possible for me to do this? Thanks.
I would use Parallels or VMWare and use the second drive to hold the virtual machine. That way the VM only uses the space that it needs and you can still use the remainder of the drive for other things, not to mention that you would not need to reboot to run windows.
Also Time Machine does not back up a boot camp partition. -
I am going to buy a mac mini i7 with 3 thunderbolt displays for forex trading. the question is if i use bootcamp and run windows on the mac mini will the displays still run the same way as if i was running it on Lion?
No idea if Windows will do it, but you can run Windows without Bootcamp & have OSX available at the same time, which should give you all the Monitors that OSX uses.

Apple TV mirroring issues even with Mac mini,airport extreme bought at the end of last year,and an iPad 2
I have the same issue with ATV3 and iPhone 4S. Everything works properly, no buffering issues when watching netflix, vimeo, youtube BUT when I try mirroring even a small 15sec iPhone movie it stutters and buffers and results to a choppy playback..same with larger mp4 files such as 1-1.5GB, buffers forever and never plays, I just re-encoded the same movie to 700MB and plays perfectly..
Why Apple, why?..so close..I can accept the bigger movie files issue, but not being able to playback properly an iPhone movie is funny..I recorded a movie with lower bitrate through Filmic Pro (Economy mode, up to 16Mbps)
and plays properly.
Is there an upcoming software update going to solve the problem or is it hardware related and therefore not fixable.
Please don't reply with a network related answer, by 2012 we know how to set up our networks and everything else runs flawlessly.
I'll apreciate a fast answer, we love Apple, but if it can't play an iphone movie (or a high quality movie from iTunes) it's just not up to my standards.
Thanks again.

How does the mac mini perform with cs5
Just curious
How does the Intel HD Graphics 4000 in the new mac mini perform with cs5 photoshop cs6 photoshop?
thanks
TedJeff, I appreciate your comment, so you haven't had any problem with using the painttools in CS 6 photoshop and the 3d type etc, in other words all the features that CS6 photoshop has.
I was thinking about buying the mac mini but was concerned how it works with CS 5 (which I have) I will have to take another look at the MiniMac server with the 3000 card. I do a lot of Digital Painting primarily Painter 12.2 but and would like to use the Painter brushes in CS 5 ( have not upgraded to CS 6.) My Imac is 6 years old and really is not fast enough.
Thanks for replying
