I got my AirPods Pro new four months ago. They worked great until last night. I used them yesterday morning. When I finished the case and the pods were each about half charged. I left them by my bed all day, not plugged in to charge, but with the pods in the case and the case closed normally. I...

Hi, I have an MBP 15 "mid 2014. After upgrading to Big Sur I found that the processor could not be undervolted, it is caused by the last firmware .431 that was installed together with Big Sur. Is there a way to downgrade to Catalina or older firmware? Thank you .

MacBook Pro (Retina, 13-inch, Early 2015), has Latest OS, Big Sur, 11.5.2 (20G95), and System Firmware Version: 427.140.8.0.0. Whenever I try to boot it normally, into recovery mode, Safe mode there is a delay of 2 minutes between pressing the power button and the startup chime and apple...

I bought a USB 3.0 (USB-A) to HDMI adapter but was too late to notice it wouldn't work with Mac - Windows only; as such my Mac simply won't recognize my Sony TV. Unfortunately a return is not possible due to the damaged package, so I thought since there's the Device Firmware Update mode which is...

I need some help from the many Mac Pro experts that populate this outstanding forum :) I was commissioned to upgrade a dual 4,1 (dual quad 2.93GHz) to a fully fledged 5,1 running dual X5680’s. The machine temps were running a little high and the fans were running speedier than usual, but I...

Hello guys, on my MacBook Pro 13-inch Mid 2010 + 2+2GB ram I changed from HDD(macOS Mountain Lion) to SSD(empty) and a new keyboard(not genuine), after this process, I did a clean macOS upgraded from Mountain Lion to High Sierra, during the upgrade was some firmware upgrade and it showed...

Does anyone else have constant weird issues with the keyboard on their T1 MacBook Pro? So like... my keyboard works fine but randomly pressing the spacebar will perform the action in the wrong spot. I.e. YouTube's search bar in safari won't accept a space today. If I press spacebar with the text...

(edited for clarity) Hey guys! The last time I posted you guys were incredibly helpful, and I hope someone can point me in the right direction. Current specs: And the hard drive setup: I bought this computer as-is from my old place of work. The drives are all probably non-OEM, and I'm...

An old version of Mactracker once had links within the app to the latest Apple Boot ROM / Firmware Update, if it was available. This information is no longer listed and I can't seem to find a comprehensive table of all the old updates. To assist anyone looking for these updates, I propose we...

After having issues with my MP5.1 and it not playing the chime anymore, I followed @tsialex instructions and desoldered the SPI flash, then dumped the BootROM. My plan was to verify and flash the dump or reconstruct if corrupted. I extracted the NVRAM section and it still has SON and UUID...

Sorry for a lengthy post. This is an uncommon situation for most people so please read only if the topic particularly interests you. I bought a used MacBook Air 7,2 (MBA1) last summer, which came with no SSD. I thought it was no biggie because it was my plan to install an M.2 NVMe SSD anyway...

Hello and Merry Christmas/Happy Holidays, I have a mid-2012 13” MBP running on 10.12.6 Sierra, which I’ve been trying to update to the latest OS for some time now. Any update that is newer than Sierra throws a “An error occurred while verifying firmware” error. After removing the CD/DVD drive...

Just got a 2017 Macbook Pro with 16GB Ram, 560 Radeon and 512 SSD. It was an unbeatable offer, so I couldn’t pass it up. The person who owned it before me used it to live stream, and has installed different versions of free streaming and server software - only heaven knows what else on it. The...

Hi folks, my 2019 5K iMac (which came with Mojave from factory) doesn't recognize when booting (with alt key pressed to access the boot options) a USB installer of Mojave and backwards (El Capitan etc), they literally don't show up when boot options appear. Funny thing is, it ONLY recognizes a...

Hello! I hope this is the right place. I tried to post to the Netkas forums but it's not sending me an activation email for some reason. I have an iMac 4,1 I picked up from a garage sale that I'm trying to install Linux to, but can't. I believe the core issue is that I cannot update the boot...

Hey Everyone— Sorry to start a new thread on this, but I wasn't sure which old one to tag onto, and most of them are, well, old. And I'm in a time crunch. I've got a 2009 Mac Pro 4,1 that I need to upgrade to 5,1 firmware, but it just isn't having it. I've upgraded probably a dozen machines in...

I've seen it mentioned a few times that firmware updates don't always work when booting from non-Apple storage. Well, I took a moment to check the firmware on my 'MacBook Pro (Retina, 13-inch, Early 2015)', the MacBookPro12,1 A1502 model, which had its Apple SSD die out of warranty and which now...
