  • Question AHCI with Bootcamp Windows 7 on Macbook Pro (please help!)

    Hello, I've been running into issues with my Early 2011 15 "Macbook Pro since I used Bootcamp to install Windows 7 64 bit Home Premium on my new Samsung 840 Evo SSD, I installed in it." What I read, it meets the criteria to run AHCI, but for some reason, I can do activate or install the Intel series 6 Chipset AHCI drivers.

    I was thrown around the web with people saying: they got their SSD to work on the Windows partition, but I can't understand what I'm doing wrong.

  • Black screen on startup after update of nvidia driver geforce 8600M GT XP home with Bootcamp on dual-boot MacBook Pro 3.1

    My computer is a 15 "MacBook Pro Intel Core 2 Duo dual boot Windows XP family. I recently upgraded to Bootcamp 3.1 that caused a major graphics display problem: the screen resolution has been set to 640 x 480 and wouldn't all interface fit properly on the screen, making it difficult to use to completely unusable. Finally, I figured out to roll back the Nvidia GeForce 8600 M GT driver of the 197 present in the previous version of 195.

    It's all working again.  XP, the interface and all my apps worked fine.  However, a couple of my applications asked me to update the driver, and I am just curious stupidly.  So, I turned on the system restore, backed up my XP using Winclone partition and tried to update the driver again. This time, the problem is even worse. Once XP has started, the screen goes black and I don't have access to the operating system at all.

    Is it still possible to roll back the graphics card driver without wipe partition, completely reinstall XP through bootcamp Assistant and then reload my clone? I have the XP installation dvd, but do not know how to proceed with him.

    Thank you

    OK, I solved my problem. I managed to solve this problem by booting in safe mode using my installation cd.  This got me to the home user interface screen where I could access the nvidia folder and reinstall the previous version of the driver.

    Hope this helps someone else out there with a similar problem.

    Good luck.

  • Can be upgraded a macbook pro logic?

    I own a macbook pro 15 "retina (mid-2015) 2.2 GHz with intel graphics Iris. Now I regret not getting the AMD graphics card and I was wondering if the two cards (one with the graphics card intel) and one with intel and AMD are intercompatibles? If so, apple would be able to sell me a new logic board and install it for me?

    Bruno

    P.S. I search google and found a lot of "can I put the graphics chip"-> No, I can't, but I can't find anything on the whole logic board.

    First of all, understand that we are all end-users like you and not employees of Apple, so what I say is based on the experience of visiting the stores Apple and reading the reports of similar in these forums requests, only not to have special service Apple policy knowledge.

    You can ask an Apple Store on a such update, but their policy seems to have always been 'replace in kind.' which means that they will put in the same room, you have now, but not an uprated one. Who wouldn't help. If you bought the MBP in the last 14 days directly from Apple you can return the computer "not asked" refund of the upgrade to a more powerful version. If you purchased from a third-pary dealer, this option is not available.

    If you are no longer in the 14-day grace period, then your only real option is to sell the one you have now and apply the product to a new one with the options you need.

  • Should I upgrade my MacBook Pro 17 "2011 at El Capitan?

    Unfortunately, I was one of those who have upgraded to Yosemite when it came out. It affected my logic board and is part of this recall, apple does a year since last February. All has been well. I was wondering if there was some known issues with one of the users who may have upgraded to El Capitan? Thank you for your response.

    I have a 17 "2011 MBP with El Capitan installed without any reported problems.  I have 16 GB of RAM installed and a Crucial SSD 1 TB.

    Understand that the only time where we MUST install a more recent OSX really is if there are applications that need it.  Other wise, it is an option.  That said, I've read some suggesting that El Capitan might be more effective than Yosemite.  I have no reason to say that.

    Ciao.

  • How to upgrade my Macbook Pro RecoveryOS?

    A few months ago, I upgraded to OS X El Capitan. It has been mostly well except for the Protection of the integrity of system (SIP) always so annoying feature. Since I've updated, I found that my boot rEFInd Manager now does not appear at startup, actually, preventing me to boot into my linux partition.

    Just as important, I can not add my unique Esperanto to PressAndHold.app characters because SIP doesn't let me change file permissions. In addition, SIP cannot be disabled because my RecoveryOS is too old for some reason any! According to the profile subject, I have version 1.0 of the RecoveryOS. In order for me to run csrutil disable I must run RecoveryOS version 2.0.

    I am running the latest version of OS X El Capitan (10.11.1), so I don't know why the RecoveryOS did not update during the installation. I have a Mid 2012 15 "Macbook Pro (no Retina Display, identifier (9.1) 2.3 GHz Intel Core i7, 16 GB 1600 MHz DDR3 RAM, a 512GB SSD Samsung Pro 850 and NVIDIA GeForce GT 650 M 512 MB graphics card). Please specify anything in the comments. Thank you.

    To update the recovery system, you will need to reinstall OS X, you can do either in recovery recovery Internet if your model is compatible with it.

  • Upgrades to MacBook Pro 2012

    FYI: It's posted on the forum iPad 2 because it's the registered Apple device I own for the forums, so if a moderator could move to the Mac section, I would appreciate it.

    Hello everyone, first time poster here (and I hope a first time Mac owner, as well). I have the opportunity to purchase a MacBook Pro for $799.99 new 2012. (http://www.ebay.com/itm/Apple-MacBook-Pro-Computer-Intel-Core-i5-13-3-Display-4G B-memory-MD101LL-A/401157900851? hash = ite...) My question is this: it is better to buy a MacBook Pro of 2012 at a low price to exchange the RAM 16 GB and add an SSD? I like the fact that are not fixed the main components of the system board with the Mac, as well as the CD player is a nice bonus, but not a must.

    If someone has done this before, could you share cost & products you used? I'm leaning toward Crucial RAM and an external hard drive Samsung EVO 850. The RAM I could redeem myself, but the player I would have a local shop do ($115 for work).

    Mainly, I'm a student on a budget trying to keep costs down while still being able to move in the Apple computers category. Frankly put, I just got it with Windows. I'm not a graphics design student/etc so the retina does not matter that much to me (and I compared side-by-side at the Apple Store). I really need a high quality machine that will last for a while.

    Thanks for your help.

    With a SSD and extra RAM, it is a very beautiful Mac laptop. Crucial RAM is excellent, and the Samsung should be fine too (although I myself would get that Crucial also).

  • Advice/cost for the upgrade of MacBook Pro memory

    I have a mid-2009 13-inch MacBook Pro. It has 2 GB of RAM and I want to update 8 GB of RAM. I heard it is expensive to have Apple install memory, but I really do not trust myself to install it alone! Does anyone have an idea of what it would cost (for the work of Apple and memory) for this upgrade? And if no Apple, anyone have any suggestions for qualified but cheaper alternatives? Thank you!!

    Dailey,

    You can upgrade RAM yourself at a reasonable cost.
