The Mac Pro 2009 (Model 4,1) is a legendary machine, but its original firmware limits it to older macOS versions and slower CPUs. By using the Mac Pro 2009 to 2010 Firmware Tool, you can "upgrade" your machine to a Model 5,1. This unlocks support for faster Westmere Xeon processors, higher-speed 1333MHz RAM, and official compatibility with newer operating systems like macOS High Sierra and beyond. Many users encounter a "script error" or "server connection error" when using the original tool because the servers hosting the firmware files are no longer active. Below is the fixed method to get your Mac Pro updated. Preparation Requirements Before starting, ensure your system meets these criteria: A Mac Pro Early 2009 (4,1). macOS High Sierra (10.13.6) or earlier installed. System Integrity Protection (SIP) must be disabled. An active internet connection (to download the official Apple support packages). Step 1: Disable System Integrity Protection (SIP) The firmware tool modifies system-level files, which modern macOS security blocks. Restart your Mac and hold Command (⌘) + R to enter Recovery Mode. Go to Utilities > Terminal. Type csrutil disable and press Enter. Restart your Mac normally. Step 2: Download the Fixed Tool and Support Package Because the original tool’s automated download fails, you must provide the firmware manually. Download the "Mac Pro 2009-2010 Firmware Tool" from community mirrors (like Netkas or MacRumors). Download the official "Mac Pro EFI Firmware Update 1.5" directly from the Apple Support website. Mount the Apple .dmg file so the "MacProEFIUpdate.pkg" is visible on your desktop, but do not run it. Step 3: Run the Firmware Upgrade Open the Firmware Tool. Click "Upgrade to 2010 Firmware." If the tool asks for the file, point it to the mounted Apple Firmware DMG. Once the tool finishes, it will instruct you to shut down your Mac. Step 4: Flash the Hardware Shut down the Mac Pro completely. Press and hold the Power Button until the power light flashes rapidly or you hear a long, steady tone. Release the button. A grey screen with a progress bar will appear. Do not unplug the Mac during this process. The tray will eject; this is normal. Troubleshooting Common Errors Script Error / File Not Found This happens because the tool looks for a dead URL. Ensure you have the Apple EFI 1.5 DMG mounted on your desktop before clicking the "Upgrade" button. The tool is designed to "scrape" the data from that package locally if it can't find it online. 5,1 to 4,1 Downgrade If you ever need to revert, the tool also supports a "Downgrade to 2009 Firmware" option. This is rarely necessary unless you are selling the machine in its stock configuration. Benefits of the 5,1 Upgrade Once the "About This Mac" section shows "Mac Pro (Mid 2010)," you can enjoy: CPU Upgrades: Install 6-core or 12-core Intel Xeon X5680 or X5690 processors. RAM Speed: Memory will now run at 1333MHz (if the CPU supports it) instead of 1066MHz. OS Support: Native installation of macOS Mojave (with a Metal-capable GPU). If you hit a snag, let me know: What macOS version are you currently running? Are you getting a specific error code ? Do you have the original Apple EFI DMG downloaded?
