Users who are running OS X 10.10 (Yosemite) should upgrade their OS before updating.Even 14 years into its existence, I’m finding my Mac Pro 1,1 to be one of the most incredible investments I’ve ever made. It came with 16GB RAM, the awful 7300GT, and the mid range 2.66 GHz x5150 CPUs.Users who are running macOS 10.13.1 should update to 10.13.2 before. I acquired my first one in early 2016 for 130 dollars. Hello everyone I am the owner of two Mac Pro 1,1 Computers and they are absolute beasts It blows my mind that they have the performance they do from 2006. OS X El Capitan Features Compatibility All of the above Macs support the operating system interface refinements as well as the updated Safari, Mail, Notes, and Spotlight applications.Hi Low Enders! It’s the Bash man again, with another happy episode of trials and tribulations getting my Mac Pro 2,1 in a stable triple boot state (queue crickets, darkness, and crackling campfire as you roast marshmallows and read on).The whole idea of upgrading a Mac Pro 1,1 for me started out of a curiosity: I began researching how to use the nVidia 210 Silent video card (with no native Mac drivers) in my Mac Pro 1,1 and was disappointed after many dead-ends, finding no readily available answers, but I refused to give up.Mac Pro 1,1 GPU/CPU upgrade. If your Mac isn't listed above, and it was released before June 13, 2016, it isn't compatible with OS X El Capitan (10.11).
Best Video Card Pro 1,1 El Capitan Mac OS X 10Secondary optical updated to an LG BD-XL/DVD-RWThe only drawback is that the 1,1 and 2,1 max out unofficially at Mac OS X 10.11 El Capitan (and you need to avoid installing a specific security update for El Capitan which breaks the 1,1 and 2,1 from booting into El Capitan any longer), but how can one complain running 14-year old hardware that was supposed to have reached the end of its line at Mac OS X 10.7 Lion, which was released 9 years ago?! I have Mac OS X 10.10 Yosemite on mine, which is perfectly stable for now and worlds ahead of Lion. Added a GeForce 980Ti and most recently a Radeon HD2600 XT to my repertoire of GPUs Added an extra SSD to serve as a dedicated Windows Boot Camp Disk Dual Xeon 5365 CPUs and firmware flash to a 2,1 I’ve upgraded away though and have really made this thing a beast by adding the following since the initial purchase from a LEM swap lister:That’s where the GeForce 980Ti comes in. How can you expect to play modern games and squeeze the most life out of your applications with an official Apple AMD Radeon (X1900, HD 2600 XT, 5770/5870, etc.) or Apple NVidia card (7300, 8800, GT120, etc)? While these were all competent GPUs in their day and generate boot screens, they are now getting too long in the tooth for many things – especially for use with gaming and some of the most recent web applications. From the point I got my OSes where I wanted, sure – I could have just used one EFI supported GPU and called it a day, but that would not do. The point of this article is how on Earth can one get the absolute most out of this machine in a Tri-Boot scenario of OSes that have different fundamental requirements?So how did I do it personally to get the absolute most out of it with three different OSes that have different needs? I have Yosemite and Mac OS X 10.6 Snow Leopard on one SSD and Windows 10 (64-bit) on its own SSD for Boot Camp (getting 64-bit versions of Windows also requires a bit of a hack but is completely stable). ![]() At first I thought I had pinned it down to the fact that the Cinema displays used single link DVI and I had a mix of single link DVI, dual link DVI and HDMI cables to adapters running, but that theory was short lived as that too wound up failing, so it had to be the KVM right? Nope – even connecting displays directly proved to cause issues (unless you only connected one display per GPU). This would all prove to work in Snow Leopard just fine and it would work in Windows 10 perfectly with any combination of the GPUs being actively displayed, but almost every single time the 980Ti had displays plugged in and when I had the NVidia drivers in Yosemite being loaded at boot (to enable the 980Ti), it would crash or go into a boot loop or would simply revert to Snow Leopard or Windows.I tried a myriad of adapters and connection types. My goal was to split off the Apple Displays into 2 viewable sets of 4 “displays” on the KVM (dual outputs of HDMI and DVI from the GTX 980Ti) on one set of inputs on the KVM and dual outputs from the flashed 5670 (again HDMI and DVI) on another set of inputs on the KVM and again – an isolated input from the Radeon 2600 on the Dell display (I also tried with the third input from the 5670 via VGA on the Dell). Unfortunately, since adding the HD 2600 and KVM back into the mix, I ran into all kinds of stability issues. I also initially added a third display when moving to the HD 2600 as a third card – a Dell 2007FP (4:3 aspect) at 1600×1200 so I could get boot screens and keep it isolated.I then added the Apple Cinema displays to my resurrected dual head DVI KVM (IOGear Miniview GCS1644), which was fixed by a stroke of luck of simply replacing the PSU (it had died a few months ago and I set aside). This surely was not good on the PRAM battery or the long term health of the system, so I was searching for a better solution and found that the Radeon HD 2600 XT (stock card from the Mac Pro 3,1) was both bus powered and fully supported in Snow Leopard and Yosemite. Chrome os mac emulatorI wound up moving my 50″ Pioneer 101FD Elite (9.5G Kuro) to the office from the gaming loft. So what does a die hard gamer do?I abandoned the dual display concept, which I do like to have at times and went big… real big (and also gained/upgraded in several other areas by making this swap). Not an ideal solution either (slightly better most likely than zapping PRAM every time for several scenarios), but not very seamless. I even have a spare VGA connection that I could add the MDD G4 or Cube to. It all works perfectly and without mirroring needed! Since the display settings are saved, the proper primary displays will work under each of their respective OSes until the PRAM dies or if I have to reset the PRAM. When I want to play games or do certain things in Snow Leopard that need more power, or if I wanted to boot with Mac Drivers in Yosemite, I simply select the input with the flashed 5670 and when I’m booting into Yosemite with NVidia drivers loaded or Windows 10, I just select the input with the 980Ti connected. During boot if I need to change OSes, all I have to do is select the input on the Pioneer with the 2600HD connected to it to get the boot screen. I just switch the inputs based on what I want to do.
