Yes of course there is a specific reason. The last version of Xcode needs Yosemite for programing iPad, iPhone or iPod apps. There are prior versions of Xcode but the last version is always desired. Roberto.

Gracias amigo Hervé. It looks like only NVidia could save me. Yesterday I installed Windows 10 Technical Preview on this Dell laptop and works so fine with this hardware. So sad I can not do the same installing Yosemite. Thanks a lot. Roberto.

Amigo Hervé, Thank you so much for still being with me on this thread. After some hours of intense online research I found a couple of cards fully compatible with my Laptop. I also found a great video tutorial on youtube showing how to open and replace the video card securely and easy: - How to Replace the GPU in a Dell XPS M1710 - NEW DELL XPS M1710 or DELL PRECISION M90 512MB FX3500M VIDEO CARD http://www.ebay.com/itm/NEW-DELL-XPS-M1710-PRECISION-M90-512MB-FX3500M-VIDEO-CARD-PR004-YF209-02879y-/121575525864 * Now, asking for advice and experience on NVidia video drivers for Hackintosh, Do you know if this NVidia FX3500M will work on Mac OS X 10.10 ? Are there drivers for it ? Please let me know. Gracias.

Hola amigo Hervé, Thank you so much for your so fast, kind and detailed reply. It is sad that a driver for my GPU is not available for Yosemite. I just bought a SSD drive for this laptop and is performing for my needs quite well and better than new. Since finding a driver will be impossible there is another path I can take. How about buying and installing a new nVidia GPU card module for the Laptop ? Base on your experience is it feasible ? Any nVidia GPU mobile card recommendation ? I am sure this cards are modular, can be replaced and can be found on eBay. Someone has gone this route ? ------------ For the Wi-Fi part of my problem I have found one Wi-Fi USB Stick made by IOGEAR, model GWU625. It is a USB adapter that has drivers at the manufacturer Web site for Mac OS X 10.10 ( Yosemite ): http://www.iogear.com/support/dm/driver/GWU625 It has a nice price of about $18.00 USD plus shipping at the B&H web store: http://www.bhphotovideo.com/c/product/751127-REG/Iogear_GWU625_GWU625_Wireless_N_USB_2_0.html I will buy one on the weekend and give it a try. ---------------- Hope you can help me further with the Video Card problem and possible solutions. Thanks a lot in advance. Roberto.

Hello Forum, Here Roberto from Mexico City needing some help with my Dell Laptop Hackinstosh install. I own a Dell XPS M1710 which has the following main components: - CPU: Intel Core 2 T7200 @ 2.00GHz ( 2 Cores ). - RAM: 4GB ( 2 DDR2 SDRAM Samsung Modules ). - Chipset: Mobile Intel 945PM Express. - GPU: NVidia GeForce Go 7950 GTX ( with 512MB, PCI Express x16 ). - Display: 17 Inches. - Resolution: Max and Native Resolution of 1920x1200x32. I have been successful installing a copy of Mac OS X 10.10 ( Yosemite ) on the laptop following the tutorial at Hackintosh Zone. All is working fine on the laptop ( Power Off and Reset from the OS X, The DVD-ROM, the Ethernet Port, The TrackPad, A Wireless USB Mouse, USB 2.0 Ports ) except the Video and the Wi-Fi. The Chameleon Boot Loader shows the following string about the NVidia card: "UnKnown 512MB NV49 [10de:0297]-[1028:019b] :: PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0," And always boot with a generic Video Driver which is VERY SLOW and set the video resolution to 1280x1024. Yosemite using the "System Information" app shows the following at the Graphics Adapter Section: - Chipset Model: Unknows - Type: GPU - Bus: PCIe - Slot: Slot-1 - PCIe Lane Width: x16 - VRAM (total): 512MB - Vendor: NVIDIA (0x10de) - Device ID: 0x0297 - Revision ID: 0x00a1 - ROM Revision: 5.71.22.45.06 Do you know if a driver exists for my NVidia GPU on Yosemite ? Or any other fix or hack I can use to have the full video speed and resolution I have on Windows ? Please let me know and thanks a lot in advance.
