In my MP 5,1 has 3 boot drives with: Ventura, Monterey, Linux/Ubuntu. I chose this setup so if I somehow "ruined" one of the disk I would still have a bootable system. Also it should allow me to upgrade the Monterey to Sonoma and if that turns out to be a disaster I should be able to fall back...

Hi GNU Linux bootloader friends. I need to have a Windows 11 or 10 USB Installer in a Flashdrive to be on the ready to fix any Windows installation on any computer (Mac or PC) and any EFI (old Macs use EFI) or UEFI (relatively new PCs and new Macs use UEFI). I burn the Windows .iso using Rufus...

Hi, I tried following the instructions on this page to upgrade my Mac Pro (2013) to Sonoma. I got as far as installing the OS, and then I was met with the following screens shown (pics). When I try to reboot or install the old OS, I cannot get the Mac to stop rebooting and start over. Does...

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...

What does it mean when the installer said, “The sampled color is not equal to the first color, this isn't an Apple logo boot image” during install?

Curious as to whether the position of HD/SSD sleds makes any difference between slots one, two, three or four? The presence of a non-bootable—and also unrecognised 8TB HD—in the left-most position, on start-up appeared to prevent the machine from advancing beyond the chime, despite the presence...

Hello, hope anyone has a tip to get my Mac Pro 4,1 booting into the OS. Symptom: no matter what I try, this Mac keeps just booting into recovery mode. (GFX are fine, nice gray screen with apple logo -> recovery-mode) Failed attempts so far: - remove all disks and do clean install from USB-stick...

Hi friends. I was upgrading to Ventura from Monterey 12.4 this morning and my power cut out. My 2019 27inch iMac is now bricked and only runs the fans at max speed after pressing the power button. No screen turn on, all black. I've attempted the usual power cycle, pram, smc, etc to no avail...

!9,1 iMac, macOS 12.6: So I want to boot into web repair mode. I shut down, then hit Power button and hold Apple+Option+R. Why do I have to sign into my network router now, never before On Ethernet? Why is the booting process taking so very long once I sign into my network, the process crawls...

While I guess I’m not completely computer illiterate, as I get older it feels like I’m not far from it. Always before, when I’ve had problems I’ve been able to come here and, after some searching, find the answer to my problem. This time, maybe because I got frustrated, I didn’t think to come...

I tried Googling this but only get generic answers or solutions to different problems. I recently reacquired a Mac Pro (7,1) and it worked well initially. When I added 2x spinning disks and a SATA ssd using a sonnet J3i, it takes a long time to boot. The spinning indicator spins for 3-4...

Hello, I was wondering, if I were to get a FireWire 400 hub, can I boot from things connected to it? I am asking because my iBook G4 only has one FireWire port and I wasn't sure if this is a viable solution. FireWire drives are pricey and I know that I can't boot from a drive connected to my USB...

I own a MacBook Pro from 2017 which originally cost $3,000 direct from Apple. In October, the TSA was doing a random search of by bags during travel and stepped on my MacBook. Despite a clear footprint, they claimed they received it that way. In either case, the left-most 3" and bottom-most 2"...

I've tried two wired keyboards, one of them Apple, but it just goes straight to the internal SSD. No options. How do I fix this? It's a 27 inch 2009 model, feel free to move this to 'Early Intel' if needed. Thanks!! x

Hi, trying to fix a friend's MacBook air (early 2020). A drink was spilt over it last year, so opened it up and it's in great condition as only had to clean the usb-c ports which had gone bit crusty. Then plugged it in to charge and it loads to the last bit of the status bar then will reset the...
