MAC PRO EFI FIRMWARE UPDATE 1.5 NOT INSTALLING DRIVER
MAC PRO EFI FIRMWARE UPDATE 1.5 NOT INSTALLING UPGRADE

This happened once or twice, with me pushing Update, then it saying it had been installed.įinally I just went to my computer's Applications -> Utilities folder, loaded the EFI 1.7 installer, and followed the instructions (letting the computer shut down, then turning it back on, waiting for the gray progress bar under the Apple icon as it updates, etc. So I switched to another tab in the App Store and switched back to the Updates tab, where it told me to update again. But then, even once I'd clicked on the Update button, it downloaded it and said it was installed (see screenshot below) but nothing else happened.

The only difference from my last attempt is that, this time, the Software Update feature (in the App Store) discovered that I needed an upgrade to EFI 1.7. I even double-checked System Info again just to be 100% sure that the downgrade had gone through (see two screenshots below). Thanks again for the help! To be completely sure, I just went through the whole process again - in order: resetting SMC -> resetting NVRAM -> downgrading to EFI 1.6 -> upgrading to EFI 1.7. Given these circumstances, and others I have not mentioned, if anyone has the right to say, 'not my problem', it is the SSD manufactures. But people expect the SSD manufactures to somehow support a product the chipset and PC manufacture refuse to support, will never be used in a PC again, and haven't been used for several years.

If Nvidia or Apple would fix the driver software, then these PCs would work with any SATA III SSD. The issue is the obsolete, unsupported Nvidia SATA chipset and driver, not the SSDs. Yet another firmware update is needed to set it back to SATA III. But then the SSD has been turned into a SATA II drive on ANY PC it is used with. The firmware update sets the SATA protocol information from SATA III to SATA II, which the outdated Nvidia controller and driver recognizes, and does not shift into SATA I mode. The only manufacture that is currently doing this is SanDisk, and it is the standard work around for this issue with the Nvidia SATA controller and driver. I must disagree about the 'most other' manufactures updating their firmware to fix this issue, that is not the case.
