boot

I'm trying to install any debian-based version of linux (ie, Ubuntu) on my Mac Pro 7,1 but am unable. I ran the Ubuntu desktop live-usb one time and managed to get ubuntu mostly installed on a separate nvme drive in a PCIe slot, albeit ruining my windows bootcamp partition on the Apple internal...

I used to use rEFInd as a boot loader, but with the upgrade to Big Sur there have apparently been changes to the firmware that interferes with rEFInd's operation. So I am back to holding down the option key. Yay. <--(sarcasm) If I tried to boot normally, rEFInd should kick in and take me to...

4,1->5,1. Can I boot W10 on a PCIe 2.5" SSD if I'm just cloning my current W10 over, not a clean install (as I understand, you can't clean install over PCIe)? When I was initially installing W10 on this Mac Pro, I remember it was impossible to do thru Bootcamp, although Bootcamp drivers were...

Hi - in my iMac 15,1 I have USB 3.0 and ThunderBolt 2. I am considering an external enclosure connecting via TB as a boot option if I will see appreciable performance gains. I have a 1TB Fusion drive going on now. Looking for connecting 2 NVMe's. A double enclosure would be choice. One...

Hi, I just wanted to introduce myself by asking for help. I was introduced here by B S Magnet because I was told you folks are a community around PowerPC/early Intel-based Macs that are no longer supported by Apple. I know the MacBook I currently have is notorious for its finicky GPU, but with...

Hey guys so I've got an iMac mid 2007 24" model number a1225 and I'm having some issues with it. When I try to boot up the computer I hear the chime and then the screen stays white and I get nothing. I've replaced the hard drive so I know that's good. I have software available to load I've...

Hi all, I have an early 2011 15" Macbook pro, yes the one with the graphics issue ?. Keeping this one alive has been a real struggle, having Apple "repair" it on three different occasions before they accepted fault...anyways I'm having a new issue that is leaving me scratching my head. Several...

Even after I select my Catalina partition as the default, or boot into hard disk selection, my Mac still boots into macOS recovery instead of the OS. Any ideas? It still finds my catalina users which is the first screen on macOS recovery.

Recently my friends macbook updated to Catalina and he had issues with wifi and the screen flashing. He decided to factory reset it and now it won’t boot at all, and booting into recovery mode brings this screen up. Is there anything I can do for this?

Howdy, I bought a 64gb ram upgrade kit from OWC for my brand new 2020 5k iMac, 27 incher. However, strange boot issues abound when I try to install all 4 sticks at once. 2 OEM sticks and 2 empty slots = boot normally 1 OEM stick + 3 OWC sticks = boot normally 4 OWC sticks = failed boot When...

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...

Hey everyone, This morning I woke up to my iPhone X stuck in reboot mode (Black Screen & Apple Logo). I was just on a long trip and accumulated tons of media which is why my storage is completely full. I am desperately trying to figure out how I can fix this WITHOUT performing a factory reset...

On my 27" corei7 mid2010 iMac, i get every now and then a white screen, that seems to cover up the users login page. This occurs just before the Apple logo and the Chime sound. Normally when this occurs, thinking that its a freeze, i do a restart by using the power button. But today i acted as...

The T2 chip and Apple SSD is more interweaved than I or the Apple Tech Support thought. I installed a Samsung Nvme 970 Evo Plus via Pcie slot in my 2019 Mac Pro to serve as the OS drive. This would leave the original 4TB Apple SSD that the Mac came with as my Media drive for video editing...

Bootcamp will not let me install anything besides window 10 and I cannot find the instructions to create a bootable windows 7 usb using catalina anywhere online. Please help!

I purchased this 12-Core Mac Pro 5,1 (see my sig) as-is a few weeks ago from a local reseller for a very low price. They had almost two dozen they were looking to move and in hindsight. I probably should have bought two for parts redundancy alone. My plan was to spec it out (mostly for photo...

Recently I have to inserted functional Windows 10 HD from another Mac Pro 5,1 into one of empty HD bays inside Mac Pro 2,1 2007. I didn't touched Mac OS Drive. Selected Windows volume as startup disk, restarted and Windows successfully worked. But now i want to start Mac OS on another drive and...
