I have some serious problems with my iMac that I've been experiencing for a long time now, but they're really getting on my nerves now!
I have a 2006 20" iMac (the last revision of the white ones before the aluminum redesign), 2.16 GHz, 2 GB ram, 250 gig hard, 128MB ATI X1600 Mobility.
I have a 2009 Mac Pro that is running 10.10.1. It is using a Radeon 4870 still from the factory. I have had a mostly flawless experience in the last 5 years with the system, but it has lately been displaying graphical problems and then freezing completely. After the display does quirky stuff that I am attaching in the image, I can only move the cursor. No other actions can be performed, and the only option I have is a hard shutdown with the power button. Usually after I do this, the machine will boot with the chime, but no startup screen will ever appear. It just sets blank. The only way I have found around this is to hold the option key, then boot to my primary drive.
I notice this seems to happen after the computer has woken from sleep. But, the issue originally appeared for the first time after updating to the newest Logitech Control panel for my mouse. I thought it was that, so I removed it and am no longer using that at all. The issue still exists.
Here is an image of what the screen typically does.

Mac Pro, OS X Yosemite (10.10.1), (Nehalem)
Ive had my macbook for about 2 months and its seemed to working just fine. However today while listening to music it decided to lock up and freeze for a good minute before it would unlock and continue playing the music through itunes. It did this a few times so I finally decided to restart the computer. The first time I booted it it froze on the apple logo and the loading circle. I killed it and rebooted, it takes about four to five minutes to get to the desktop picture, and another five to pull up the main menu bar. I am going to let it sit over night and see if it gives me any error messages, however; I still haven't seen the dock at all, and ive let it start for about twenty minutes now. It will usually show the top menu bar and then the mouse will give me the sbod while it slowly loads up the top menu bar, and usually the clock is a good few minutes behind.
I have tried a pram zap, draining the power off the board, checking the sata connection, unplugging the power, and I ran a hardware check at start up and it said everything was ok. I am currently typing on my tank of a toshiba laptop that still works after being dropped multiple times and has been heavily used for a good 3 years. The mac has been completely useless is most work situations. Its a refurbished 2.53ghz 4gb ram 9600m 512mb 15" mbp. I am thinking of reformatting it and hoping it works, and then selling it and using the money for a new toshiba or a custom built desktop, because I just cant deal with the amount of money and time I have lost trying to deal with this thing while I could have been getting work done.
We're running an IMac G4, 700 Mhz, 768 Mb Ram with OSX 10.3.9. We have been having a problem with freezing/crashes for a long time, accompanied by distorted graphics and have been unable to get to the bottom of it. A screenshot of what happens is linked below. The pattern is that we will start working on something, then the graphics will become distorted in a small area. Then sometimes we'll get away with working for a bit longer, or sometimes it goes wrong right away. The graphics distortion spreads, and either the computer freezes and has to be restarted or we get the grey error box saying to restart. We've tried: adding more ram - it still crashes even with simple apps. using macaroni to schedule maintenance tasks unplugging hardware to see if there's a conflict. Have also tried clearing the PRAM on reboot, which seems to increase the chance of it working for a while.
View 2 Replies View RelatedI desperately seek help from the community as Apple itself doesn't seem to care much.After updating to 10.7.4 my Imac has become unusable. It goes into a loading state just about every 10 minutes at which i can do little more than move the mouse around. I know it is the new update causing this (and not the hardware) because i also have a Bootcamp partition which works totally fine. Does anyone have any advice or solutions? Unfortunately i am currently not in the position to reinstall my system. I have no more space on my external HD to back up everything and am not in the position to purchase a new hard drive. And in my opinion, i shouldn't have to resort to such drastic measures because Apple released such a terrible update.

iMac (27-inch Late 2009), Mac OS X (10.7.4)
I've had my 27" iMac (3.06GHz) for a few weeks now and yesterday I noticed some weird artifacts appearing on the screen, very randomly.
They will pop up all over the screen but if I "Show desktop", they will go away for a bit but sometimes reappear again in different areas of the screen. I restarted the computer but that only temporarily fixed the problem.
Anyone know what's causing this and how to fix it?
Have a late 09 i7 27" iMac with XP SP3 installed on Bootcamp partition. Even after turning down brightness in BootCamp control panel all the way down, I still feel like I'm staring at the sun. Screen is still way too bright. No such issue in OS X. Is there any Windows app (similar to Shades) that allows further brightness reduction? With brightness as is, Bootcamp is pretty much unusable to me.

It apparently failed two weeks ago, and I just got the machine back after the Apple Store replacing the card.The only graphical glitches I had on the Imac, was the faint line that would run across the screen that you could see on a white background if I left a program's window opened to long; and when using Safari, while encoding a dvd, trying to open up a new tab I would get images of whatever I was encoding in the new safari tab for half a second. Then it would correct itself and bring a blank safari page.
View 2 Replies View RelatedApple on Wednesday afternoon issued a number of updates, addressing high processor usage and other glitches in its 27-inch iMac, as well as various security updates for Mac OS X 10.6 Snow Leopard and Mac OS X 10.5 Leopard.
27-inch iMac updates
Two updates released Wednesday address issues with the 27-inch big screen iMac, released in October 2009.
"27-inch iMac EFI FW Update 1.0" is recommended for all systems with quad-core Intel Core i5 and Core i7 processors. The update resolves an issue that caused high processor utilization when playing audio through the headphone output, and fixes a problem that prevented the display backlight from turning on after powering on the iMac.
The 2.1MB update is available for download from Apple. It requires Mac OS X 10.6.3 or later.
"27-inch iMac SMC Firmware Update 1.0" fixes Target Display Mode compatibility issues on the 27-inch desktop iMac. The 397KB update also requires Mac OS X 10.6.3 or later.
I have just upgraded my iMac from snow leopard to Lion and now it is running incredibly slowly to the point of almost unusable.

Just got a refurbished 27" Imac I5 with the Radeon 4850 yesterday.This happened twice yesterday, so today, when I powered on I had my blackberry ready to record.As you can see theres a large green band (yesterday it was accompanied with a red one) that spans the vertical aspect of the screen. The bars disappear after 30-1min.I've tried searching and haven't found anyone with a similar problem. http://www.youtube.com/watch?v=mGK3LYb23mc
View 1 Replies View Relatedcurrently i have a blackbook and imac core duo, 17 ". My macbook beats the imac in everything except graphics. Before i got my imac i seriously considered a g5 dual 2.0, but the money wasnt there. I see an apple refurb dual 2.0 for 1599, and im sure i cud get one a lot cheaper used here or on another board. How much of a performance increase will i see IN APERTURE going to the PM, if any? i would need a good increase to justify it, and eve then im not sure my parents would be ok with me spending a few hundred bucks to upgrade
View 5 Replies View RelatedI recently read somewhere that I can actually change the graphics card on my mac. If so where can I buy the ATI Radeon 4850 graphics card? and how much will that set me back?And could I get this upgrade done by my local nextbyte retail store?If it is possible to have nextbyte upgrade my card would they send it off to apple?
I really just need this card so I can play aoe3 on all settings high and be able to handle games like cod4, quake and all those graphic hungry games.
I just installed Windows 7 on my 27" i5 iMac, and it was working fine until just now. It froze completely (I could move the mouse around) for a minute, and then it unfroze.
I kept using it, and then it froze again, but this time I had to restart by holding down the power button. It just happened again, and I had to restart again.
The only thing I have running is Chrome, and this is a fresh install. What's going on?
I have tried many permutations: different settings on the AirPort Express, different configurations of Ethernet cables and Wifi, you name it. In every case, there are at least occasional patches of silence lasting 0.5-5 seconds (playback does not pause during this silence). My findings: If the AirPort Express is not plugged into the Ethernet, but instead forced to use the Wifi coming out of my AirPort Extreme nearby, then the glitches are almost constant. It is so terrible, during five minutes of "playback" there might be thirty seconds of actual sound.
If the AirPort Express is plugged into the Ethernet, it doesn't matter whether my MacBook Pro is plugged in. There will be occasional glitches. At least some of these glitches are coming from the MacBook-end, because they sometimes coincide with Time Machine backups or processor-intensive tasks. What the hell? Is AirTunes just bad? Or is it my MacBook Pro, is it overloaded or does it have some errant process stepping on the AirTunes' toes?
MacBook Pro started giving me terrible glitches, Where 1) Applications will quit unexpectedly and 2) I will get the gray cover over the screen with text saying I need to restart my computer.
This is happening quite often and I would really like it to stop..
I noticed it all started happening after I installed ProTools LE.
I've already erased my internal hard drive and reinstalled snow leopard, then put my necessary files back.
I have also upgraded my RAM and HDD, about 3 months ago and it's been working flawless until I installed ProTools LE.
If I use the arrow-key shortcut (no matter how they are setup in Systems Preferences) whilst holding an App's title-bar, to switch it between spaces, the HUD showing which Space the app has been moved to only shows up sporadically. I've tried changing Spaces settings, turning it on and off, restarted etc. and it still does it. If I use the number key shortcuts it displays fine now matter how quickly I move an app between spaces. If I use the drag method it's also fine... but you can only do that slowly.
If I use the titlebar & arrow keys method very slowly and wait for the HUD to fade out before switching to another space its fine. (i.e move from 1 to 2, HUD shows, wait until it fades out, then move it to space 4, HUD shows). But if I flick an app between spaces quickly the HUD only shows sporadically after the first switch. Sometimes the desktop image will flicker in front of everything for a fraction of a second. I have an Alu MacBook and I can achieve these results after a restart with only the Finder running.
So turned on the computer today after installing Snow Leopard yesterday and first the menubar had graphical glitches but it disappeared when I clicked the icons. Went to my desktop sometime later and I saw this Bug or is my display giving up?
View 16 Replies View RelatedI'm looking to buy Snow Leopard for my early 2007 intel 24" white imac before the end of the year. It currently has Tiger on it. So are SL's glitches being fixed and will all the issues be cleared up before the end of the year?
View 3 Replies View RelatedA while after I installed Snow Leopard I started to notice odd glitches I can't think how to describe them. They appear randomly and don't follow anything specific. Anyway has anyone else experienced these? They only started appearing once I had snow leopard installed. I have an early 2008 Macbook 2.4 GHz with an Intel GMA X3100.
Here are some screenshots so you can see what I'm on about.
I've never really had a problem with my macbook, but for the last two weeks or so, I can't watch any Flash videos like YouTube. It'll work for about fifteen or so seconds and then the whole thing will start skipping and the whole computer acts choppy. Firefox (or Safari) CPU usage spikes, and the computer gets really hot. Then I'll have to wait for a minute or so for the macbook to cool off before I can use it. I've tried downgrading from Flash 10 to Flash 9 -- no better.

Internet seemed very very sluggish when working at home via a wireless access point...
Tested with ping and found the reason:

Yikes... what's going on... almost every packet being dropped causing essentially unusable websites.
Test 1: Unplug wireless access point and plug Ethernet cable directly into MBP

Conclusion 1: It's not the modem or ISP, but the WAP
Test 2: Try wireless with my trusty Linux netbook...
No problems with dropped packets.
Conclusion 2: It is the MBP + wireless that is the problem
Now what can I do about it?
I have googled around and found some older threads about problems with wireless with OS 10.6.3 and various ad hoc solutions, but nothing really current.
Has anyone else with the Alum MacBook loaded Vista and experienced sound glitches when playing any sounds? My machine will have sound stuttering lasting 3-5 sec occuring every 2-3 min. Works fine in OS_X but never in Vista. I,m trying to decide if I need to return or exchange the machine. AppleCare is clueless on the problem other than blaming the drivers. I have reloaded Vista Home prem 32bit, BootCamp 2.0, Updated 2.1 BootCamp drivers, changed the realtek driver in Vista, updated to 1 month old realtek new driver, and lastly disabled the onboard audio and installed a new Creative external USB sound card ALL to NO Avail. I have 5 days left to return the notebook, but otherwise I love the new MacBook.
