firmware

Hi guys. The firmware update on my early 2008 Mac Book Pro failed. The system now turns on and plays the SOS beeps. Instead of running the auto repair the system then reboots and plays the beeps again and so on. I have tried to find firmware recovery disks but none are compatible with this...

Besides switching back to the OEM SSD just to update the EFI firmware. Are there other workarounds? Opening the iMac for each OS Update that requires an updated BootROM will be a pain. If my boot drive is an External NVMe SSD (ex: Samsung X5) will I ever have problems with the BootROM when...

I have an early 2006 Core Duo iMac that I've upgraded the CPU in to a Core 2 Duo 2GHz. I've tried using the Firmware Tool to upgrade the firmware of the computer, however, all I get is error 5530, which I believe is because it tries downloading the firmware from a dead link. I could not find any...

Hi guys, I have a 2014 Macbook pro which has had its screen replaced. The brightness controls have now stopped working after I reinstalled MacOS from El Capitan too Mojave. I know there is a way to fix this by replacing the screen firmware chip to the correct one, suppose to be the E1 chip...

Hello! I've been trying to flash the firmware on my Mac Pro 2009 4 1 to 5 1 in order to be able to upgrade cpu to 12 core as well as RAM. It's currently running Snow Leopard and doesn't have a partitioned drive (no recovery mode, which means I'm unable to disable SIP). I've tried to flash the...

Hi, while browsing to buy a dual cpu mp5,1 I came across a single cpu 4,1 (MB871) where the seller explicitly states that the "drive is unbootable" and that the machine has a firmware lock. He attached photos of a boot-screen that shows a lock and a password field below it. I did some...

I've been running Yosemite for hardware support and aesthetic reasons. (I can theme it so it doesn't look like it was made by color blind slave labor children.) But, Mojave looks livable, and I'm tired of Yosemite's networking issues, so I'm ready to attempt the leap. I intend to install it on...

Hey, so, I know the GTX 670 Works, and is arguably the best price to performance GeForce Card that will work with Macs. Is there any way to flash the Firmware, and have the bootscreen show? I have the 2600 XT, but Mojave literally wont work with the card in it. I'm currently on El Capitan, as I...

Could use some advice here. While I had an RX 580 handy, I thought I'd throw it in a couple of aux/utility Mac Pros and bring their firmware up to 140.0.0.0.0. On the first one, a 12-core 2.66GHz MP4,1>5,1, I observed the first attempt caused the Mojave installer to hang w/ beachball after...

This is an obscure card for the Power Mac G5, but I have heard of it being done and I know someone here did it by replacing the ROM, but I think I have heard of doing it without having to do that. I bought an unused 7800 GT with 256MB of video RAM. Ignoring I have no experience whatsoever with...

Apple mailed me that I have to service my MacBook Pro 2017 13 inch no TouchBar An ssd firmware update needs to be applied in order to prevent possible data loss As I live hundreds of miles away from the closest authorized service can someone who has already done the update give me the version...

Just throwing a post in here in case people don't find their way to the Mac Pro forum. First off, I got my Mac Pro prepped per @tsialex 's fine instructions, found here. Firmware: Got my firmware updated. Read the thread above and follow directions exactly. Graphics: Removed incompatible...

Hi, After a loong time (almost 2 years), I had some time today to try one more time to revive a Mac Pro 4.1 that I had to stash away since it died on me back in April 2017. The original post was this...

I just tried to upgrade to macOS Mojave (from the latest macOS version before Mojave) and I am getting the following error: macOS could not be installed on your computer. An error occurred while updating firmware. Quit the installer to restart your computer and try again. As it suggests, I...

alright I’ll make this quick because I know that there’s an easy answer for it, but I just can find it. I’m trying to update to mojave and since I’m on .0085, it requires a firmware upgrade, I know that to firmware upgrade you need a flashed gpu, the only working flashed gpu I have is a Radeon...

My system is pretty fully loaded with two CalDigit FASTA 6-GU3 Pros connected to 2 internal SSDs internally each as well as connecting to two external docks. This configuration has been in use for 4 years and very stable. After applying the EFI patch the system started becoming unstable. No...

Trying to update firmware on a piece of hardware (zhiyum crane gimbal) with a mac but having trouble with the downloaded software. I've turned off the apple security measures. I keep getting an unmountable disk error with the Zhiyum dmg software. I've tried downloading the software using both...

This is a warning to save time for other people. The High Sierra 10.13.4 installer is bugged. It CANNOT install firmware updates when booted from USB. According to one thread below, it's due to an inability to "bless" the USB drive. In my opinion, it seems more like the USB-booted installer...

I know firmware hacks exist for MacPro1,1-1,2 and MacPro4,1-5,1. I have heard someone claim to have used an Xserve "firmware hack" to enable use of X5690 CPUs and 1333MHz RAM. I can't find any Xserve firmware updaters searching web, aside form Apple's official updates from years back. Anybody...
