nvram

I've been using TotalFinder for ages because of its visor and all of the convenience and aesthetic features that are superior to Apple's Finder, and I have no interest in going back to Apple's ghetto Finder. Unfortunately with Apple being a totalitarian corporation it has been increasing the...

I just woke this mornig with an idea, like to poll the interest for an opensource project for solving NVRAM / BootROM headaches and accelerate BootROM / UEFI / GPU Rom / GOP developments. There are so many users around doing critical NVRAM / GPU card flashing which costs a lot of time while...

Hello Mac friends. On this Late 2015 iMac 5K w/ Monterey latest (iMac's firmware hav all been updated), I've reset he SMC and NVRAM/PRAM, I've reset the Bluetooth using Terminal, I've diagnosed it with the built-in Hardware Diagnostics which says everything is ok but does the screenshot indicate...

I kept getting that screen with the little folder with a question mark in the middle of it. Sent it to be serviced as the apple advisor recommended instead of buying a new one like i should've.... They said it was a battery issue and that I should change out my screen as well. Paid 500+ bucks...

Hi everyone, I would appreciate a bit of a help here. I've a Mac Pro 5.1, and I've recently updated to High Sierra, the problem I'm facing is that the NVRAM variables are removed after restart of the machine. I'm using GTX 980 ti GPU and it was working fine with El Capitan, it should work...

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...

Can anybody type "nvram -p" in Terminal on new MacBook Air 2018 just to see what is the default parameters, especially if there any string called "AutoBoot" and any parameters for that? Because for now I'm in some experiment with this setting. For example, as you may know, "AutoBoot=%00" turns...

I’ll try to explain my situation as the detailed as possible. I have a 2009 4,1 Mac Pro I bought from someone about a month ago. Since purchasing it, I’ve flashed the firmware to 5,1 and began doing hardware upgrades. So far I’ve installed the X5690 Xeon (it’s a single CPU tray version), added...

I'm running Mojave on a 2018 13" MacBook Pro (2.3GHz i5/16GB) and there's a frequent graphics issue where the whole system stalls every few seconds. Even under low/no load, if I move the cursor around it'll freeze and then jump to another spot ever two or three seconds. If a video's playing...

I'm attempting to try out Next Loader. However I've run into a problem with the `bless` command (not with Next Loader itself). `bless` can't seem to change or read the efi-boot-device NVRAM variable. This is on a MacPro4,1 flashed to a 5,1 running macOS 10.13.6 from a SATA SSD formatted as...

The keyboard and trackpad of my MacBook Pro 2015 suddenly stopped working. I searched the Internet and did a SMC and PRAM (NVRAM) reset with an external keyboard. The PRAM reset (I reset the PRAM with command+option+P+R as explained here) helped solve the issue: I could use the keyboard and...

I recently switched from a 2017 MBP to the new MBP. I don't quite remember what combination of settings I had on the older MBP, but I used to be able to plug it in (with the lid closed), and it would turn on automatically. I would plug it into a USB-C hub that was connected to power and to an...

It has been happening for 2 months or so. I though it was a heat related problem. I changed the thermal paste on the CPU and GPU. Heat seems to make the crashes more frequent but it happens when it is cold, too. I tried to reinstall the OS. Now it runs a lot cooler but it still freeze every...

I have a mid '14 MacBook Pro 15" that will not boot due to a (1) typo I made in the nvram's boot-args, and (2) inability to reset the nvram. I suspect this is because my machine has a dead firmware battery, which it may have always had- I've always noticed that exhausting the main battery would...

Hello Community, a few days ago I bought an used MacBook Air. Everything's alright so far. After connecting to my Apple AirPort Express I noticed that the Wifi connection is slower than I ever experienced. The Wifi-module must be working as I can connect and use my browser. To open the Apple...

I have a huge problem after installing rEFIt. After i used the installer and restarted my Mac 10.9.5 wont start again. I know there is the option within safeMode (holding down shift key), but i cant get in to safeMode start up somehow. Even when I inserted a USB drive with the Mac installation...

Hi there, I have been scouring the net for a solution to my issue, and none of the responses have worked so I hoped I might be able to get some new advice. I opened the lid of my A1398 (2012 Macbook Pro 15" Retina, 256gb SSD) this morning and the trackpad and keyboard had stopped working. I...
