I am repairing an iMac 27" , late 2009 model (EMC 2374), 2.8 gHZ.  It has a bad video card causing stripes on the screen and problems booting.  The video card is an AMD ATI Radeon HD 4850 Video Card.   This model is very hard to find and very expensive.  Does anyone know of any other compatible video cards for this model apple machine?  thanks

I have the ATI Radeon HD 4850 graphics processor with 512MB of GDDR3 memory installed on an . Given that my current card is malfunctioning and that versions of that card are prohibitively expensive, which cards could I theoretically upgrade to?

Has anyone had the chance to test the compatibility of MacTeX on the new M1 Macs (Mac Mini, Macbook Air and Macbook Pro)? What is the performance like?

I have a macbook (2.26 GHz Intel Core 2 Duo upgraded to 8GB 1067 MHz DDR3 RAM) running OS X version 10.6.8. I do a lot of prototyping for high performance computing on this macbook (running c++, fortran, mathematica, matlab, etc) and often work in parallel.  I have noticed that my computer gets hot so I have installed 'Temperature Monitor' and find that, when running difficult jobs, it can break into the 90 degree (C) range. I know this is not good, but is this incredibly dangerous? after seeing what values should i begin to get worried?  Secondly, I would like to clean (and maybe even replace?) the fan to make sure I am getting the best ventilation possible. Will a can of compressed air do the trick? how expensive/worthwhile would it be to open up the case and replace the fan?  Any help would be great - thanks!

I would like to know the model of my graphics card. I think it may be an ATI, but I want to be sure!   I have Ubuntu 11.10 (32 bit) and an Asus A6 VA laptop.

My question:   Can anyone confirm or disprove the support of NVMe drives (like the Samsung 960) by the Sintech M.2 PCIe SSD MacBook adapters for macOS Sierra and High Sierra, or would you have any information that could help me confirm or disprove this support?  Below are the results of my research so far.    SSDs comparison  "Official" MacBook SSDs  Officially supported MacBook SSDs are really expensive. For example, with the Macbook Air/Pro 2013, 2014 and 2015 models:   : $299 for , $399 for , $649 for  : $524 for 256GB, $649 for 512GB, $949 for 1TB.   Equivalent PC SSDs  Globally, an officially supported MacBook SSD (PCIe M.2 AHCI with a proprietary 12+16pin connector) cost from about $1 to $2 per GB, while equivalent PC SSD (PCIe M.2 AHCI and NVMe with a key M connector) cost from about $0.4 to $1 per GB.  NVMe:   : $196 for 512GB (low quality) : $219 for 500GB : $316 for 480GB   AHCI:   : $300 for 480GB : $450 for 512GB   So standard PCIe M.2 devices seems to be up to 3x cheaper than the MacBook PCIe M.2 SSD. Plus, NVMe SSD are globally way faster.    NVMe SSD compatibility?  Connector adapter  At first for the connector, I often seen the   recommended to use the AHCI SSD above in a MacBook Air/Pro. The product page clearly stipules only compatible with a limited set of AHCI SSDs, but I do not see any reason for these "incompatibilities", as there is no other software/hardware standards for the PCIe M.2 AHCI models. It seems they simply give as compatible the list of the AHCI SSDs they've tested, and as incompatible the most known NVMe SSD models.  Interface compatibility  Then for the interface, what I understand from AHCI/NVMe is that it is only a controller interface, depending on the system drivers on the MacBook and not on the hardware itself.  Which seems to be consistant with:     I emailed the store which sell that adapter and problem is that macOS doesn't support 3rd party NVMe SSDs, but Windows 10 and Linux do.      -- From a  on a upgrade video with a AHCI SSD and the Sintech adapter.   So Sintech may have given these NVMe SSD as incompatible not because of the adapter incompatibility, but because of the destination OS incompatibility.  System support  Finally for the system, macOS now support NVMe SSDs, from unofficially OSX El Capitan (with a  to boot) and natively macOS High Sierra (even as boot, see an article about the  and a confirmation from the ).  I sent an email to Sintech to get more informations on their adapter. I got a reply with some references (added to this post), but no answer since.  Edit (23/06):     Unfortunately, we are busy in other projects, and still can't get new system to test it.     Similar researches  After I created this post, I seen there is some people with the same question in other communities, waiting at the same step. I share the links there in case of some of them got a return from a test with the Sintech adapter or an other one.  On    Por Chumjan (02/27/2016):     I think about to upgrade. Samsung 950 pro is interesting. But i'm not sure it can use for this model.  trumanhw (12/21/2016):     You can buy an adapter from M.2 to MBPr or Air for about $20... (...) The REAL question is if the NVMe protocol will be a hiccup (as in, I don't personally know that answer) ... and if it'll get the full speed of the 950. In principle, I don't see why it wouldn't. And I WILL be testing this out.  Fabio (06/10/2017):     [ About the patch ]. It is meant to be used on hackintosh but I think it might work on a macbook pro from 2015 with the adapter and a nvme ssd like the samsung 960/950 evo/pro. If someone tries or has tried it please let me know.

I don't know how to update Nvidia graphic card drivers on MacBook Pro Retina. I have been a Windows user and a gamer for a long time where we expect frequent driver updates.   My expectations revolve around whether Nvidia releases graphic driver updates for Mac and how to check for pending updates.  Where can I see the versions of drivers on OS X?

Is the current version of Ubuntu usable on a PPC mac?  I've got a "lamp shade" mac from 2003 that I'd like to recycle into my first Linux computer.  I'm not a programmer.  So it appeals to me that Ubuntu is a download/upload kind of thing.  Apple iMac G4 1.25GHz  Any suggestions?

At that location there is an ISO image which is described as "This image is adjusted to work properly on Mac systems."  What specific problems on the Mac does this image address that the standard images don't? I ask because I need to know which ISO to recommend to Apple Mac users.

I bought an  compatible with a  Socket AM3 processor?  I know strictly speaking, the Lion Square specifies AM2 but I'm a little confused since AM2 and AM3 are suppose to be socket compatible (I'm a little confused here as well but I assume it means an AM3 board will support AM2/AM2+ CPUs).   However, will there be a problem with chip height and spacing? Or do people have experience asking ASUS for a standoff adapter?

So it turns out I can not install Sierra because I have a Mid2009 Macbook Pro. I wanted to update to El Capitan, but it turns out its no longer available on the app store?  Any ideas, how to get El Capitan?

I've never supported Apple in any way, but I like their hardware. As I've just purchased and got working a nice Apple wireless keyboard (bought second-hand!), I'm curious about the possibility of buying a second-hand MacBook and installing Ubuntu on it.   What, of what's important, isn't working? Notably, I do Flash Player development from time to time, so I do at the very least need to get a 32-bit debug player installed. (I usually run 64-bit, so I'm familiar with having to tweak things to get it all working properly) I'd also need to be able to play DVDs with CSS, run Google Chrome, etc. Is it fairly similar in capabilities as a non-Apple computer as far as what I can use? It seems that there's a different architecture used, namely PowerPC, and I don't know what this means to me as an end-user.   Can anyone recommend me for or against installing Ubuntu on MacBookPro?

I noticed in this thread the OP successfully managed to connect a 30" cinema display to the new Macbook Pro USB-C, with full resolution:    I have the official Apple dual DVI adapter, going to a displayport > USB-C adapter like yours, however the screen does not fire up.  I then tried a multi adapter instead of the single displayport > USB-C, which worked but only at 1280 resolution:    Would the official Apple Dual DVI adapter not work?

I've been told it is important to use matching DIMMs when installing memory to take advantage of the 128 bit throughput. I'm looking to buy a new 27" iMac (mid 2011) which has 4 memory slots. If I put matching 2x2GB in 2 of the slots and matching 2x4GB in the other two slots, will that reduce its throughput or cause any problems?   Do all 4 have to match or do each set of 2 need to match?

I have a MacBook Air 13 inch laptop since 2011.  Quite recently the screen had problems.  It start flickering, changing colors, and vertical lines appeared in the middle of the screen.  All these are starting when I move the screen backwards, forward or when I am lightly pressing with the fingers the top of the screen.  This is also the only way to re-adjust to normal operations. Any recommendations?

I want to test the memory of my video card because there are vertical lines on my screen. I have done some basic troubleshooting and it seems that the problem is in the video card. I want to validate that the issue is the video card by testing its memrory. I have found software that is used for Nvidia cards with CUDA support, but my card is the Nvidia GeForce 7600, which has no CUDA support.
