MacBook :: Using Corsair 4GB Kit?

Apr 10, 2009

I bought two sitcks of ram made by corsair (CM3X2GSD1066). I installed them in my macbook aluminiun 2.4 and I have some stability issues. All memory tests using even apple hardware test say that there is no problem but when watching videos or doing random taskes the computer hangs and the image gets distorted. Is there any way of making this memory work as I have seen that it works fine for other people in their macs.

MacBook Pro :: Working Experience With The Corsair 256GB SSD On The Mid-09 UMBP?

Aug 11, 2009

From reviews, it looks like the Corsair 256GB SSD is not bad except the random write speed.

Anybody is using this SSD on the mid-09 uMBP? any issues? I'm considering a SSD for my mid-09 15" 2.53GHz uMBP, but it seems that several members have reported issues for using OCZ SSDs on mid-09 uMBP.

MacBook :: Screen Doesn't Come On When Opening Computer?

May 2, 2009

My wife is having an issue with her Macbook. The screen works great, when it comes on. However, 80% of the time, when she opens the laptop, she has to jiggle the screen back and forth to get it to come on. Sometimes it takes several minutes.

Any idea what that could be and what the solution would be? Could it just be a loose connection somewhere?

Power Mac :: G5 Doesn't Boot - Making It Boot?

Jun 11, 2012

my old 2x2Ghz PM G5 (late2004) doesn't launch the boot sequence:

- when pushing power button, the blue led turn ON as long as I keep it pushed. If not pushed, it light off but yet the fan are running.

- no chime

- the fans turn on normally and the hard drive start a little to make noise once powered up.

- no video on display, the screen is black.

- the keyboard is not recognized anywhere I plug it.  

- after a minute or two of non activity, the fans start to blow full speed (guess its a security measure for saving processor) 

I ve done the reset of PMU several time (unplug the power cord then push the button at bottom of mother board)As i dont have access to keyboard, I can't start on Target mode to check if the HD is failing all.I ve removed all RAM extensions and left only one pair in slot 1 (J0), and changed the pair to avoid a faulty RAM.I only have a redlight on motherboard if I don t put back the glass panel.I ve check the voltage of the lithium battery, and yet its the original, the voltmeter says its 3,6V...

MacBook Pro :: Computer Doesn't Seem To Have The Appropriate Soundcard To Produce 5.1 Sound

Sep 4, 2010

I have just purchased a set of logitech x-530 speakers to go with my 2010 MBP. It was a bit of a rushed buy without much research and as such I have realised that the computer doesn't seem to have the appropriate soundcard to produce 5.1 sound (is this correct). At the moment I can only play 2 channel sound leaving the other 3 speakers hanging about. Do I need to buy a external sound card or is there an adaptor

MacBook Air :: Battery Runs Out / Computer Doesn't Go To Sleep

Feb 28, 2012

Anyway, sometimes I'll leave my MacBook Air on without the power adaptor attached, and the battery will drain.That's all fine and dandy.The problem is, is that instead of going to sleep LIKE IT SHOULD, it will completely turn off, and everything I had up (web pages, anything and everything) will be GONE when it starts back up.

OS X V10.7 Lion :: MBP Doesn't Boot Into Safe Mode And Doesn't Wake Up "normally"

Feb 22, 2012

I am using a 15" MacBook Pro Santa Rosa (mid 2007), 2.2 GHz Intel Core 2 Duo, 6 GB memory, with a 240GB OWC Mercury Extreme Pro SSD (15 months old). Lion 10.7.3. Computer doesn't boot into Safe Mode AND also if it "goes to sleep by itself" (I don't touch it for a while, then it falls asleep) after some time when I try to wake it up I get the Spinning Ball of Death or a black screen and the only thing I can do is press the power button for some seconds to power off. It wakes up OK if I, either close the lid or Apple icon-> Sleep. 

WHEN TRY TO BOOT INTO SAFE MODE: Immediately after the startup chime I press the Shift key, after 2-3 seconds get the login window, key in my password. Instead of logging in, it goes to a screen with the Apple icon, underneath it, the Apple spinning gear and underneath that a loading bar.  After quite some time the loading bar disappears, the gear goes on spinning for a LONG time, then black screen, startup chime again and login window. Then, when I key in my password, it just logs in as usual, no safe mode. 

I tried to write in Terminal “sudo nvram boot-args="-x"”, BIG mistake! It got my computer into a  loop of those screens. I don’t exactly remember what eventually got me out of this loop (I think I booted from a clone, then started with the Lion CD and wrote back “sudo nvram boot-args=""” in Terminal.  Also set up an additional administrator account but all was the same. Tried verify/repair disk, everything OK. Eventually I erased completely the HD (not Recovery HD) reinstalled Tiger, Snow Leopard and Lion again, downloaded all applications/software/programs I had, from scratch and only copied the data from a backup, being sure that after that all problems will be over, but... everything like it was, no "normal sleeping" and no SM booting.

MacBook :: Unable To Charge Battery / Computer Doesn't Recorgnize The Charger

Jun 14, 2008

I have had my MacBook (aluminum) for 6 days, and all of a sudden i go to plug it in to charge (10% left) and the led on the magsafe doesn't come on and the computer doesn't recorgnize the charger (even in system profiler).

upon closer inspection i noticed the LED is on on the magsafe, it is just a very faint shade of green.I have tried a charger from a different MacBook but no luck. And i have also tried my charger and a different macbook and it charged it just fine.. so it's probably not my charger.

Any ideas?? i know i can go get it replaced.. but i would really like to not have to take a 45 minute drive to the apple store if i can avoid it.. (unless this problem is serious and should be replaced) also, if i get a replacement is it possible for them to just swap my HDD with the new one?

MacBook Pro :: After Sleep Mode Computer Sometimes Doesn't Recognize Wireless Connection

Jun 22, 2012

After using my MacBook Pro I close the laptop and it goes to sleep. Later when I return to it and open it, sometimes it can't find the network. The computer is able to see that I have an Apple Network available, but it won't connect.Sometimes when I try to connect, it gives me a timeout. How I fix it is to walk over to the router and unplug it and plug it back in. After I get the green light again, I go to the Apple Network and it works.

MacBook Pro :: Motu Ultralite / New SR MBP / Boot Camp Doesn't Work

Jun 14, 2007

I installed Boot Camp 1.3 so I could run Windows XP on a partition (use it for music); no problem. Set up my Motu Ultralite on the OSX side, no problem.

HOWEVER: The Motu UltraLite doesn't work on the XP partition, at all. It shows up, but no audio can be routed through it. It's a firewire audio card, if you're not familiar with it.

MacBook Pro :: Ethernet Port Doesn't Work In OSX But Does In Boot Camp

Nov 30, 2007

Been troubleshooting this one awhile...I even did an Archive and Reinstall....my Ethernet port on my 2.16Ghz MBP won't connect to anything. I get an IPv6 address when plugging into a router, but DHCP never works and a manually assigned IP doesn't work either. Reboot into Windows and it works fine...I've tried removing the Ethernet port, and have futzed with all the settings trying to reset it, but no dice. Problem started somewhere around 10.4.9, I think...I'm on 10.4.11...I reinstalled to .8 and worked my way back up...never works.

OS X :: Macbook Doesn't Boot - Blank Grey Screen, CDs Not Recognised

Nov 24, 2008

My Macbook will not boot up. I am now faced with a plain grey screen with no apple logo, chime sound or activity wheel appearing.

Like most Macbook users I know, I rarely go through the booting up process from day to day use unless the System Updater requires a restart, but this time there was a different reason for me restarting the system.

When I was expanding an archive with Stuffit Expander, the app froze up. I went and deleted the archive file knowing that it was corrupt, but I did this too soon before the app had a chance to close down properly. It became stuck as a process that couldn't be closed down. Its dock icon didn't have a 'Force Quit' menu option so, I chose to perform a restart.

The Macbook went through the startup process but took a very long time. (I guess after reading around the forums this was fsck attempting to scan and repair the potentially damaged hard drive). I mistakenly performed a hard reboot thinking the system had hung.

The second time, it displayed the apple logo and wheel for about 2 minutes before showing a circle with a line through it and no further activity. When I rebooted again the apple logo and wheel were displayed with the hard drive activity audibly in a repetitive on and off state. I left this for about 15 minutes before deciding to turn it off. At the present moment it starts up to a plain grey screen as mentioned at the beginning. I tried experimenting with removing the extra 2gb memory module but there was no difference with or without it. I tried resting the NVRAM with Option-Command-P-R but all I got back was the startup chime (i.e. the muted volume I had it at has now reset to the default level).

When Option is held down on booting, the mouse cursor is visible over the same blank grey screen. No volumes show up. I have selected the Finder Preferences option to hide all volumes from showing up on the desktop, but I doubt this would affect volumes from showing up on the boot up screen.

I have tried booting from the 10.4 CD that came with the Macbook and the 10.5 (retail) DVD. The 'C' or 'D' keys do not have any effect either.

I think my options now are either to try and obtain a firmware reset CD which might make it possible to recognise volumes again, or there's the possibility that I'll have to get a new hard drive. Can you suggest anything else I might be able to try?

On the subject of hard drives, if it turns out that the Macbook's hard drive is beyond repair and I need a new drive I only have a caddy for 3.5" PATA drives which I use for Time Machine. With an appropriate 2.5" SATA caddy is there any way I could access the filesystem in Windows? How else could I format the drive to the correct FS?

MacBook :: Computer Will Not Boot?

May 25, 2012

I have a mid-2010 MBP. Earlier when I was not actively using it, it started beeping very loudly in evenly spaced intervals every few seconds.  It seemed unresponsive, so I turned it off by holding the power button. Now it will not boot up. The little white indicator light comes on and I can hear the fans turn on, but that is it. It will not even go to the boot screen. 

I had the logic board replaced about a week ago, but otherwise nothing new has been installed software or hardware.

OS X :: Macbook Pro (2007) Black & White Horizontal Lines & Doesn't Boot Up?

Dec 18, 2009

There's some known documented issues concerning the Nvidia graphics chip in the particular model of macbook pro I have.

Basically when turning on the machine, the screen is filled with black & white horizontal strips like a piano keyboard, but thats it - it doesn't actually boot up fully at all, you cannot hear the hard drive running !

Would the hard drive have anything to do with this ?

I explained this to apple telephone support & they informed of the article

& stated that the symptoms were linked.

On taking the mac to an apple store they ran a special 'firmware' boot up 'test' using an instore ipod to determine if it was a faulty Nvidia chip, so as to prove to Nvidia, the company funding the repairs whether it is that to blame.

Because the machine didn't even boot up & complete the 'test' they couldn't say whether it was the graphics chip - so 'no free repair' under extended warranty & the final answer was as usual ' buy a new logic board' that will cure it !
