I have a Mac Pro 5,1 that stopped booting. (no fans, no chime) plugging / unplugging PSU make red LEDs quickly blink as it is expected. DIAG button only shows yellow 5V LED Power button doesn't do anything. Shorting sys_pwr (vertically or horizontally) doesn't do anything also What I've tried...

This is addressed primarily to owners of 2016+ 13/15-inch MacBook Pro with Boot Camp volume on internal SSD. I'm trying to set Boot Camp volume (located on internal SSD) label displayed in Startup Manager (Option-boot, boot loader) to something different than Windows. The commands I use are...

Both the Terminal and Chrome appeared after I booted up this morning, despite neither of them being set to open at login, or as login items for my user group. I thought it may have been becasue I only closed their windows and didn't quit the actual applications, so I tried to reproduce that, but...

This might be a strange question but here goes. When I use my Mac, it sometimes just cuts power when the battery is at high percentages like 90 percent. I've been able to solve this by calibrating the battery but now I have a new issue. When I get the battery to zero and plug in the charger, my...

Hello, so I downloaded the Minstaller for a LUT package and it decided to instal Python 3 in my core services. It keeps asking me to install developer tools at Startup. I have tracked the file to the core services folder and cannot delete it. Can anyone give me directions how I might? Even if...

I installed Big Sur when the public beta came out, no funny business, all official, and the installation went without a hitch (MacBook Pro, 2017) However, often when waking from sleep I will get the flashing ? folder showing the startup disk is "missing". It's not every time, may 25%. To get it...

Hiya folks. Well, my workstation was having issues. I had another Mac Pro (4 core) that I'm working on now. But my 8-core needed some work. I had two GeForce cards in there, SSD, 4 other drives, PCI SSD, USB3 PCI card...24 GB RAM. It was shutting down, so I thought the power supply couldn't...

Have had kernel panics before, but today it wouldn’t wake up at all. I could get it to come back via an SMC reset, but the minute i plugged a peripheral in, it crashed. Tried again with reset, restarted, but nothing. Now, the SMC doesn’t even seem to work. I’ve also tried the NVRAM reset...

I was recently given an iMac (2008 I think) from an old lady who said it wouldn’t Start up. I thought I’d give it a go but I’m more of a pc guy so could do with some help. It turns on to apple loading screen but stops halfway through & the screen goes dodgy like in the pics. Any idea what this...

I started having problems when my Mac would start, seeming the hard drive had eventually corrupted and couldn't get past the start up bar I have purchased a new drive Sandisk SATA iii 512mb + Heat adapter (OWC) but after checking realised this may not be compatible as the iMac only has SATA II...

Hi folks, I have a fairly old Macbook Pro (I think it's 2011/12). I was using it last night then the battery cut out. When I went to charge it up and power up, it gave me this screen (pic attached). Do you know why this has happened, and do you have any advice as to steps I should take? I...

Just bought another cMP 5,1 Server (Mid 2012) Quad-Core (single CPU). When I first plugged the power cable in it started automatically before I even hit the power button. All good, so I upgraded the firmware from the original 7F to 89, then popped a RX 580 in and upgraded to 144.0.0.0.0, but...

Hi all, I've scoured the forums and reddit and couldnt find a real answer for new macbook pros but start up times (pushing the power button, to the login screen) are substantially slower than my prior 2015 macbook pro on Mojave. Is this normal? Is there a way to optimize? Any help would be...

Hello! A few months back I started to get a screen pop up on startup called windows.plst (see image attached). I have searched online to see how to get rid of this but have come up empty. I was on Sierra previously and upgraded but that has not taken care of this problem. Does anyone know...
