IMac :: Does 8gb Of RAM Make A Major Real-world Difference

Nov 18, 2009

Just wondering if it's worth getting a machine with 8Gb of RAM over the standard 4Gb for things like video editing, aperture etc. Can most of today's apps even use 8 gigs of memory? I assume the biggest advantage would be for running a virtual windows machine within OSX and things like that.

OS X :: Western Digital My Book World Edition II Connected To IMAC?

Mar 19, 2010

Just got a WD My Book World Edition II 2TB. I would like to reformat this drive specifically for mac. It's sole purpose is to be used with Time Machine.

I currently have the drive connected to my IMAC via ethernet. Finder shows the external HD listed under Shared as MyBookWorld and another one as MyBookWorld-Backup. Time Machine preferences/select disk shows this drive as "WD_Backup on MyBookWorld-Backup".

Using DiskUtility.app the drive DOES NOT show up!

Should I send this drive back from where I ordered? Anyone have any experience with this drive? Should I even bother to reformat?

I have NOT installed the software that came with the drive? Why should I?

IMac :: How To Delete A User From IMac After Reboot, Using Os X Install Dvd To Reset Keychain

May 25, 2010

I forgot my admin password on my iMac recently and so i used the reboot with OS X snow leopard install disc to reset the keychain, but now on my login screen, it used to be just my account name, there is one called "Other" so i went into accounts in system preferences and tried to delete it but it isnt there?is really annoying me p.s. the "other account" isnt actually an account it says "Other" and when you click on it asks for your username and password...so i type in the admin accounts name and password (admin account is the only one on this computer), and it just opens up my admin account.

OS X :: IMac 10.6.3 Takes 15 Minutes To Reboot?

Apr 8, 2010

For about a week now, every time I boot my iMac mid-2007 20" running 10.6.3 I get the following problems

-Booting takes about 15 minutes of seeing the apple logo, and a bar that fills slowly under it...

-When it finally boots all the dock icons are reset to the ones you get with a brand new mac, spaces and expose is reset as well.

-Spotlight reindexes Macintosh HD.

-Adium loses all contact icons

-Mouse loses all it's custom settings.

-Login items are gone, I have tried not to re-enable those.

-Shut down takes about 10 minutes as well, while I see only the blue screen of shut down...

It seems that it is losing more and more settings every day. Today I had to turn on time machine again, although it was on before shut down...

Is this like losing an application support folder or something like that?

Applications do not seem intact as well.

Safari loses all web screenshots from cover flow iTunes reupdates the library etc....

What's up witn all these?

IMac PPC :: G5 Stuck On A Reboot Loop

Jun 4, 2012

I received an iMac G5 from this old couple, they were going to throw it out, but all it needed was a power supply which I bought and replaced. It's been about 9 months and everything worked great, no problems whatsoever. 

Three days ago, I shutdown the computer and when I booted the next day, it would only reach the Apple logo and the spining wheel, the fans would blast loud and then it would shut down and restart again, repeating the same thing over and over.  I cannot start it under Safe Mode nor it recognizes the CD when booting.

IMac :: Screen Brightness Adjusts Itself After Reboot?

Aug 25, 2009

After every reboot, the brightness of my iMac's screen changes to 100% brightness, which is slightly annoying. Does anyone know why this happens? By the way, I'd say it does it since 10.5.8.

Software :: IMac Shuts Off At Random And Not Reboot

Jun 28, 2008

I have a G5 iMac, 1G ram, with three external HD, a MIDI keyboard, and an all-in-one Canon print/copy/scan, running Leopard. Lately, my iMac has been turning off seemingly at random, like someone has hit the power strip (although other things plugged into the strip stay on). Sometimes it will reboot when I turn it back on, sometimes not. When it doesn't, it will get partway through startup, then turn off again. There is no apparent pattern to the point during startup where this happens, it's different every time. Sometimes, it barely spins the HD before going dark again.

I took off the back and checked the power supply LED. It says the power supply is OK. I rebooted via the internal power button, and everything was fine for a couple of days. I set the preferences to "reboot after power failure" so it will reboot when I'm at work. I can go through the Time Machine backup list and see how many times it shut down and rebooted during the day (TM backs up once per hour, so when there is a significant length of time between backups, I know it shut down for awhile). The only recent addition is the installation of MoneyWell software, but this app isn't always running when the comp goes black.

Software :: IMac Starts Itself With Reboot Screen

Jan 9, 2009

In the last three days my iMac desktop has begun starting itself up. There is an audible beeping (three or four beeps) and the on/off indicator light blinks rapidly. When the screen comes up there is no desktop but a gray background with reboot instructions. When I type the reboot words "mac-reboot" the desktop comes back.

Under Logs in the system profiler I see the following message:
CGXDDisableUpdate:Updates disabled by connection 0x66-3 for over 1.000000 seconds
and
CGXBlindSurface returns-536870210
The computer is rather old, is running OS X 10.2.8 and has never done anything like this before.

I've just done an install of lion from snow leopard on my IMac. Now when I reboot, I just get the grey brushed aluminum background and apple logo slightly higher than centre and a black arrow cursor. No desktop, no login options, nothing else whatsoever appears on the screen.I've tried resetting the pram, and to access the lion recovery mode (command r on boot up) but this does not even appear. All I can get is the same empty screen and arrow cursor.

OS X Yosemite :: IMac Slow And Reboot Takes 5 Minutes

Dec 8, 2014

I updated my late 2012 27" iMac from the latest Mavericks to Yosemite.  now it takes 30+ second between mouse click and action.  For example, if I click on iTunes it takes 30 seconds to a minute before iTunes opens.  I get the pinwheel while waiting.  I rebooted and the startup hangs on the progress bar for several minutes, then black screen for several minutes, then eventually gets to desktop.

Hardware :: Drive Disconnect Randomly - Can't Mount Unless Reboot Imac

Jan 29, 2009

I purchased a Q-Drive Q 1TB in Dec for my 24" iMac, purchased it at a Apple Store. I was connected with 800firewire cable, all seemed to be working ok, time machine etc. But in the past month the drive has become a nightmare, it will just disconnect at random. At that point i cannot get it to mount, unless I reboot my iMac. I have tried to connect with 400firewire and usb2, but the same problem persists. Needless to say I am somewhat annoyed, it was not cheap. Anyone have any advice on what I should do, I'm scared to go to G-Tech for support as what I could find appears to be a nightmare. Would I be able to return this to the Apple store that I bought it from?

IMac :: Unable To Save Settings / Screen Brightness Goes Up At Reboot

Jul 23, 2010

All of a sudden, every time I reboot, my screen's brightness is all the way up. So, I go to 'Preferences' and bring it down to only happen again the next time I reboot. Not a terrible problem, I hope, but not sure why the settings of this doesn't remain as I left it last. Perhaps I have picked up something OR I have a fault which could get worse?Anyone seen anything like this?

OS X Mavericks :: Killed Runaway Distnoted Process Now IMac Won't Reboot

IMac :: Why Folder Flashing With Question Mark

Nov 15, 2010

So I went to sleep and my computer was just fine, just sitting there being normal as normal gets. I wake up and the cursor is beachballing, no response from anything, holding power button doesn't do anything, so I unplug it. Now when I turn it on it goes to the gray screen with a folder with a question mark blinking. Google told me that this means it can not find the startup disk, and my hard drive is probably toast. Upon advice of forums I grabbed my snow leopard install disk and am going to attempt a boot from disc after work today. If this does not work is it safe to assume I need to replace the hard drive? Computer is out of apple care so this will be a DIY operation.

Computer: 24" iMac, 2.8GHz core 2 duo, 4gb RAM.
Questions:
- What risks are involved with taking apart the iMac? What tools would I need?
- After I install a new hardrive, is it as simple as simply popping Snow Leopard into the disc drive and going from there?
- While I have it open, does anyone know if this model iMac has room for more RAM?

IMac :: Getting Flashing Globe When System Starts?

Jul 21, 2009

Over the last few weeks when I have been starting my computer up I get the white blank screen for a few mins then it goes to a flashing globe for a few more mins then the apple sign then it finally starts. I have been thinking about taking my computer in to get it fixed cause I cant seem to figure out whats wrong with it. I have looked it up on google and everyone seems to be saying to go to startup disk and then pick the right network volume to start up from, but when I go there there is only one choice its called "Network Startup" and there is a globe with a ? on it for the symbol. Also I read a couple places that its the hard drive warning me that its crashing? is this true? I also have had a couple freezes the last couple days.

IMac :: Flashing Folder Icon After Restart

Jun 21, 2010

I have a 24inch aluminum iMac running the latest versions of Snow leopard. It's a little over 2 years old. I can turn my computer on and all is fine, I can keep it running for hours on end and nothing is a problem. However, the moment I turn it off or perform a restart I get the flashing folder icon? It takes about 2 hours before I can boot the computer up again.

I've tried the following:Resetting PRAM and VRAM
Resetting the start up disk information through system preferences
Pulling an individual RAM module, booting up then trying the same with other RAM module (to check to see whether I have some dodgy RAM)

At first I thought it must be the hard drive, but why can I run my computer with no problems at all. I had it running for 2 days, and not a problem! But, the minute I turn it off, that's it, you can forget booting it up for at least another hour.
