OH, unless TBar can confirm whether a Flashed 4,1 to 5,1 status will allow you to Upgrade to High Sierra. TBar can confirm and give you proper assistance with that modification. TBar is RIGHT about the Limitations of El Capitan BUT, IF what I've found IS true for your System - AGAIN, you SHOULD be able to get to Sierra 10.12.6 and be able to run CUDA90. Look here at the 2009 4,1 2.26GHz CPU Hardware Upgrade Possibilities.ĪND, your RAM SHOULD be 1066MHz, NOT 1333MHz - BUT, IF it's 1333MHz the System is slowing that down to 1066MHz. (Based on your 2.26GHz CPUs.) You CAN upgrade to Sierra 10.12.6.
You have a 2009 4,1 possibly Flashed to 5,1 and are on El Capitan. My Mac Pro tops out at 10.11 (El Capitan).Īctually, I found your System on iBuildMacs. My Mid-2010 Mac Pro 5,1 is Dual Xeon 2.4GHz CPUs, 64GB ECC DDR3 1066MHz RAM, the GPUs mentioned above, one Samsung VNAND 860 EVO 1TB SSD with High Sierra 10.13.6 (17G8037 - HFS+) with NVIDIA Web Driver 387.10.10.10.40.131 and NVIDIA CUDA Driver 418.163, one Samsung VNAND 860 EVO 1TB SSD with Sierra 10.12.1 - (HFS+), one Samsung VNAND 860 EVO 1TB SSD - BootCamp Win 7 Pro 圆4, and one Western Digital Black SATA 2TB HD - one 1TB Partition for Time Machine, and one 1TB Partition for Blizzard Games, both Partitions in HFS+ Format. MacVidCards' Flashed Sapphire Pulse RX580 8GB Card - NEW in Retail Packaging: $374.95. Apple has seen fit to kill off the cMPs with Catalina making Mojave the LAST OS that a 5,1 can take. This WILL allow you to take the Mac Pro 5,1 up to Mojave, BUT NOT up to Catalina.
IF a more modern and up to date OS is important to you, you MUST go AMD/ATI and could install a Sapphire Pulse RX580 8GB Card. As TBar mentioned, to make use of the NVIDIA Cards, the Mac Pro CANNOT go above High Sierra. I use TBar's CUDA90 App on both my Mac Pro 5,1 AND my Hackintosh with MacVidCards' GTX-1070 8GB Card AND a Secondary EVGA GTX-1050. An ordinary off the shelf GTX-970 Card WILL work, BUT NO Boot Screen. The Mac Flashed EFI is IMPORTANT for a Real Mac Pro 5,1 in order to have Boot Screen, (with Apple Logo and Progress Bar), visible. Silver NVIDIA GTX-970 4GB Card, 3 DP, 1 DVI, and 1 HDMI - $375. MacVidCards STILL sells the GTX-970, BUT is MUCH higher priced at $375 - AND is out of stock at MacVidCards.
The 1050 is Low Power and pulls directly from the Motherboard up to 65 Watts, (75 Max), and I don't remember what the wattage is on the GTX-970, BUT the 970 REQUIRES dual 6-Pin Connectors - the 6-Pin Cables come with the Card. I also have one off the shelf EVGA GTX-1050 2GB GDDR5 VRAM Card. I have one Mac Flashed NVIDIA GTX-970 4GB GDDR5 VRAM Card, (used), that I paid $329 for off of e-Bay. My Mid-2010 Mac Pro 5,1 is on High Sierra, 10.13.6 with current Security Update.
