I have a Black MacBook (Early 2008). I think that I still have the factory standard RAM sticks (I bought the Mac used from a friend). I noticed today that I am running on only one gig of RAM even though I have two gigs of memory.
I installed 4x2GB memory modules. Now, I have a "Memory Slot Utility" pop-up(The memory modules are installed in the recommended slots) that pops up every time I start my computer. How do I get rid of this notice permanently?
While browsing around I've stumbled over a few references to things like "tri-channel memory" and such. From what I understand (not that good with these things) some computer architectures / CPUs are optimized for using 3 memory modules, and some for using pairs (2 or 4).
I just read some benchmark tests of the i7 with different memory configurations, and the 12Gb was is most cases on par or better than all the others when it came to performance, even better than the 16Gb one. Is the new iMac (i7) best suited to use 3 memory modules?
I bought a refurbished Mac Pro (8 core) from the apple store and added 4 Gb (2x2Gb) to the 2 Gb tht came installed. I am having a peculiar problem in seeing all four of the memory modules. The only setup that shows all 6 Gb of the memory is to have the modules in the following format: a) 2Gb modules on Riser A, positions 1 and 3 plus 1 Gb mods on Riser B positions 1 and 3; b) 2 Gb and 1 Gb mods on Riser A positions 1 and 3, respectively, and the same on Riser B.
When I put them in the logically (and aesthetically better) intuitive configuration of paired mods in positions 1 and 2 of each Riser, I can only see the modules that are in position 1 of each riser. Is this something expected in the new MacPros? Is there a disadvantage of keeping this configuration? I note that a memory installation video on line stated that the way memory is installed in the early 2008 Mac Pros has changed. Does this issue result from that change?
I'm in the process of upgrading the memory on my 1st gen Mac Pro. (2 x 3.0 Ghz Xeon). Apple publishes a memory max of 16GB., but I have seen references to these machines running more. My question is, has anyone successfully run larger configurations of memory, and will these systems recognize 4GB modules?
I get the message: the memory modules are installed in the recommended slots. Every time I restart my 2010 Mac Pro. I upgraded my memory with 3 x 2GB OWC memories. They are properly detected, and the system is working fine.
I have a 2010 i7 MacBook Pro. I came across GeForce Mac OS X Driver Release 19.5.8 and CUDA 3.0 from the website: http://tonymacx86.blogspot.com/2010_06_01_archive.html(under Mac OS X 10.6.4 Update->What we know about 10.6.4 so far...)Is it advisable to install these drivers on the new 2010 MBP? I assume that whatever included in the official Mac OS/X update have been tested. If we download and install drivers from parts manufactures such as Nvidia, we risk possible untested, compatibility problems.
My air has an interesting case of uneven backlighting especially at the edges. This is not bothering to me because I think it's a result of the very thinly made LCD, which helps this computer be so small.
Test your MacBook Air 11.6" by downloading this image and putting it in fullscreen to see if your backlighting is uneven.
I was just noticing on my shiny new unibody MacBook Pro that the glass trackpad is uneven. At the bottom left side, it's basically flush with the surrounding case. But then it dips down on the bottom right to below the surrounding case. Is this normal, and has anyone else seen the same?
With the laptop open and sitting on a flat surface (granite countertop), I can press the lower left corner of the laptop down about 0.5 -1 mm and the computer wobbles a bit. It seems that the little black feet are not the same thickness all around. I am really surprised because Apple is so fanatical about having such low manufacturing tolerances... yet they somehow overlook the feet. Anyone else out there having this issue on their brand new unibody Macbook Pro? Does this go away after the feet have time to wear down a little?
I bought the new macbook pro 15inch 4 days ago. Today I just noticed that the hinge on the back of my laptop is uneven can I ask for a replacement? I still have the 14 day warranty.
Got my Macbook Pro i7 back from Apple today. First thing I notice is that the lid is uneven on one side. Second, I also have a small nick on the lid. (extremely small but none the less.) This is outrageous. This is there store you would think they would know how to treat their products perfectly. What should I do?
Moreover I found that the display is definitely NOT new. Hate to buy from apple store. Better switch to Amazon folks. Amazon offers a better costumer serivce.
I have 2 1GB sticks left over after updating my 2.2GHZ Macbook's RAM to 4GB. My friend wants my old RAM modules, but his macbook is the black one from 2006. Will this RAM work in his blackbook?
I have a macbook pro of 8months old.The machine is fitted with 4gb ram, 2 x 2, but is able to be fitted with 8 gb.I bought 2 x 4gb of the same type of ram: 1067 MHz DDR3When it was fitted, the computer performed great, Autocad was flying. Alas, after a few hours the computer went berserk and started to behave odd, refused to open a prog, refused to stop and finally refused to re-start. When I removed the new ram modules and re-fitted the old ones, I found out that my hdd was not mountable. I did resolve the issue but lost some data in the process.
I know the Home Folder short name changing issue has been discussed already on here, and most people seem to advise either against it or to backup before proceeding. I just obtained my first MacBook Pro second hand, and it still has the previous owner's Home Folder and Short Name, even though he has deleted all his files from it, and there's only pretty much standard folders within it (Library, Applications), but nothing in them. I've been saving my own stuff elsewhere in another folder I created on the Mac HD drive. Is it fairly safe then to change his name over to my own following the steps on the Apple website, or would his home still be attached to certain important components? I'd rather not create a brand new account where I have to fiddle with settings again for everything, though I'm not sure if I may have to do that anyway. I'm using Leopard, by the way. The login he passed on at start-up still says administrator as a user name, though, not his shortname. Will that change also?
I have 3 problems with my aluminum macbook and I think that they are all related and are caused by each other.1) The hinge creeks sometimes when I slowly close the screen and I'm afraid it will only get worse as this just started happening.) When the macbook is closed, the screen is uneven. The right side does not completely close and there is a gap between the base of the computer and the screen. However, the left side is just fine unless I push down on the right side then the left side just goes up and becomes uneven.
My Air's screen is slightly darker at the bottom (only on a few millimeters, but still). It only happens on a white/light background though (I don't have my dock at the bottom). In comparison, the screen of my MacBook has a very uniform backlight. Does anybody else have this issue?
I just received my new IMac and was starting to do some typing for a school project when I noticed that the keyboard bottom stand was uneven so whenever I type it bounces much like a chair with uneven legs. I was wondering what to do because now I have to stick a credit card underneath it to keep it from moving.
I just bought the base model Mac Mini yesterday, and I am going to tear it open today to put in a bigger hard drive and more RAM. My question is...since I don't need the entire 4GB of RAM, I am happy with 3GB. The system has one 1GB chip in there already, so can I simply just pop in a second 2GB chip for a total of 3GB? I wasn't sure if they had to be installed in pairs or not. Is there any downside besides obviously the memory not being under Apple's warranty?
I have a small issue on my iBook (G4) that's been driving me a bit crazy lately. I noticed a few months ago that when I selected a song/video on iTunes to play, I would get uneven volume output on my two internal speakers. I tried restarting iTunes, restarting the computer, etc. to no avail. In addition, sometimes this problem would not arise for a few days, and then suddenly start up again.
I then dug up the program Audio MIDI Setup and saw that the sliders were uneven . Once I slid them back together, I thought I had solved my problem. Nope! It came back, and I even saw that if I opened up Audio MIDI Setup right after the computer turned on, the sliders would be skewed even before opening iTunes or Safari or some other program that used audio.
I've come accustomed to manually balancing the volume output, but the irregularity of this problem occurring frustrates me. Attached is a screenshot of Audio MIDI Setup with the issue--note the Audio Output sliders.
I want to know if the wool is being pulled over my eyes by OWC. The site says that their 4GB modules for a Mac Pro Intel Xeon Quad-Core 2.66MHz can only be put into the tower if the original Apple modules are first removed. Something makes me think that this is a salesman's bluff. Anyone know for sure? Sorry if an answer to this question has already been given elsewhere.
I know the newer Intel QPI processors have three main-memory channels, and I've seen much discussion and several complaints on these threads that Apple didn't expand their memory risers to squeeze in six DRAM sockets instead of four, so that the module count on each riser could be a multiple of 3. (And also that they should have done this for the 2009 Nehalems).
Here's my question: what kind of performance would I be losing and why if I got one of these new Westmere machines, discarded Apple's stock memory and replaced it with 4--rather than 3--OWC 4GB sticks? What I specifically don't understand is, can't the QPI fetch from any 3 of the 4 modules at once?
I've read many of the threads regarding RAM pricing and configurations for the 6-Core systems. I planned on ordering my Pro with 6Gb instead of the default 3GB, but my friend at Apple forgot when he placed the order. what I understand RAM module placement and type may significantly impact system performance for this platform. As I need to double the RAM, should I purchase 3x1GB modules to add or purchase 3x2GB models and sell the 3x1 that came with the system? Also, which is the best RAM retailer, OWC, Crucial, etc?
So my early 2010 iMac has 8gb of memory (4 x 2GB modules).I happen to have 2 spare 4gb modules that are from a MacBook pro of the same era - i.e they are DD3 1066Mhz and they will fit.So question is - if I take out two of the 2gb modules and replace them with 2 of the 4gb machines - will the machine work and will it see the full 12gb ( 2 x 2gb plus 2 x 4 gb)?
