What are the benefits of buying a MacVidCards flashed card?
You may question why you should install a MacVidCards flashed graphics card with a Mac BIOS as opposed to an official Apple released card or a stock PC graphics card. Here are a few of the benefits:
1. You can use the latest and greatest graphics cards on the market with Metal support instead of older official Apple cards. Modern cards are not only performing multiple times faster but also take less power. Only MacVidCards flashed cards gives the possibility to run the latest AMD Radeon RX6000 and Radeon Pro W6000 series in a classic Mac Pro. Standard PC cards won't even boot, despite driver support in macOS or Windows and there is no way to overcome this via any software method.
2. It enables gray boot screen with Apple logo on startup as well as boot selector, where you can select which OS do you want to boot (also on 4K displays). There is no need to use any tweaks or patchers as it always work even with no hard drive installed.
3. It allows to start macOS from Recovery partition in order to perform tasks like macOS recovery from Time Capsule or other backup devices, disabling SIP (System Integrity Protection), reinstalling macOS, fixing disk errors using Disk Utility etc.
4. It enables full PCI-Express 2.0 (5,0 GT/s) bandwidth both under macOS and Windows. Standard unflashed PC cards run the outdated PCI-Express 1.1 (2,5 GT/s) standard unless you use Mac Pro 5,1 with the latest Boot ROM version.
5. It allows to boot into macOS even with no macOS driver installed, which is very important for NVIDIA cards requiring NVIDIA drivers for proper operation. Since every new macOS release or security update requires a new driver, with a standard unflashed PC card you would have to remount the original Apple card in order to install the NVIDIA driver and then remount the unflashed PC card again. This also allows Kepler based NVIDIA cards to boot into macOS Monterey and install GeForce Kepler patcher, so they operate normally just like on previous versions of macOS.
6. It allows to install Windows from boot picker screen, even when there is no macOS drive installed or BootCamp assistant isn't working.
7. It allows to install Windows 10/11 in UEFI mode which is the most current way to boot Windows. It's faster, it's much more secure and allows you to boot from partitions larger than 2.2 TB.
8. It enables suspend and resume under Windows in UEFI mode.
9. It fixes non-existing 640x480 secondary display issue, where some software start minimized and cannot be maximized or their new dialog windows aren't showing and cursor going outside the physicial display to a non-existing display.
10. It allows to easily upgrade Mac Pro 5,1 Boot ROM with progress bar on the screen.
11. It allows to boot the system without acceleration if your old card does not boot modern macOS versions and perform update to the latest supported system.
12. It allows to set proper NVRAM variables for macOS Big Sur/Monterey on boot picker allowing you to run these systems natively without OpenCore Legacy Patcher.
13. It also works as eGPU (external graphics card) with Mac Pro 6,1 under macOS and Windows enabling support for 5K/6K displays like Apple Studio Display or Apple Pro Display XDR and much better performance than standard AMD FirePro D300/D500/D700 cards.
