I found that the EFI Partition was faulty and that I still can boot into my Debian 10 Live Medium so the solution was to reinstall macOS or to fix the EFI partition In my case, I simply need to reinstall macOS/OS X Snow Leopard and then repatch the El Capitan installer and install and then, I'm done (Yes, I can just repair the EFI partition but I've erased ...

It’s the I/o, disconnect it and it will work again. Or change the I/o board. Tried it and it worked! Good luck

There is a Ubuntu Live USB distribution called LivelyLinux that boots from Mac. It costs $29.99 and is available in two editions: Ubuntu 20.10 and Ubuntu 20.04.1. It works on Macbook Pro 2016 with WiFi, touchpad, etc. Probably should work on later models as well.

I also have MacbookPro2,1 model A1211 upgraded to 3GB and have Windows 10 64bit installed. I clean installed Windows 10 Technical Preview in 2014 (without earlier Windows version) and have been upgrading it since to version 1909 currently. To install Windows you need to ensure the disk is partitioned correctly (with hybrid MBR), somehow get the Windows files ...

One technical reason you can not use rEFInd is that rEFInd is a boot manager. To boot Windows you need a boot loader. The rEFInd boot manager instructs the firmware which file or data to boot from. The actual booting is not done by rEFInd. Grub is a boot loader. Grub may be able to boot Windows. However, Windows on your model Mac needs to interact with a ...

I would buy a cheap PC or newer used Mac. You will face a lot of hurdles with that era hardware. Let it be with Debian until you decide to replace it with a raspberry PI for $50 and run Linux on a new SOC platform.

If your installer/boot media works fine on a different Mac but fails on your MacBook Air, the issue is likely hardware (logic board). You don't need a drive to load the installer. If you boot from USB or boot from the network (Internet), it is caching the installer in memory. If you're to run diskutil list command while the installer is running, you'll ...

I recently had this exact same issue. Hardware test said I had no issues. After about another two weeks of use, my internal ssd went dead, and i had to replace it. After replacement, all is speedy again. So if its not a corrupt efi or boot partition, i would suspect you might have a failing hard drive.

Using CheckM8 Exploit, you can remove the system PIN lock, but only on a Mac device with an Apple T2 security chip.

Sad but true, same answer as stated by @Tetsujin in other words, obviously this rule holds: You can safely go back without risk to any version that came out after the Mac model came out. Else you run the risk that the old OS X doesn't know what to do with the new hardware features and becomes unstable. Reference found in Apple Support Communities

Your sticking point is actually much simpler than that. No Mac can boot to an OS older than itself. There's the occasional edge-case when a new Mac is released right on the cusp of a new OS, but otherwise, it's simply not possible. There are no drivers for the hardware in the older OS, as the hardware hadn't been invented yet, so Apple stops you from even ...

Based on klanomath's answer to the question OS volume shows as type 'FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF', you should proceed as follows. Boot to Internet Recovery Mode (or a third party drive). Open Terminal in the menubar Utilities > Terminal Get an overview with diskutil list. Assuming the disk identifier for the internal drive is still disk14, ...

A 2019 Mac is much too new to be able to boot High Sierra. In general, a Mac cannot run any macOS version whose release date is earlier than the release date of the Mac. If you have a specific need to run an older macOS version (but no older than Lion, or at most Snow Leopard Server), you can do so in a virtual machine using software like Parallels or VMware ...

This is by design. I've tested this on several iOS devices of various iOS versions (iOS 9, 13, 14 and iPadOS 14) and all do the same thing. I haven't found anything that specifically says so, but it makes sense so that if it's ever lost/stolen while in Airplane mode (WiFi/Bluetooth/Cellular off) when it comes back on after a period of time, it will ...

There are two possibilities: 1. The SATA cable connecting your SSD to the Mac is intermittently failing. This is a common problem in MBPs of that vintage. The good news is that this means the data itself on the drive is ok, and the internal cable just needs replacing. Alternatively, you could get an external USB enclosure (a box with a USB cable), and put ...

I'd try an Apple keyboard. One of my Mac Pros has a Logitech Windows keyboard, which it completely ignores if I want to do diagnostics. I have to use one of the Apple keyboards to get it to listen.

When you have power issues, the most likely cause is hardware. Follow precisely the steps to reset your SMC https://support.apple.com/en-us/HT201295 This is something you want to do once, not regularly reset it - more than three resets in a month = a trip to repair for us at work. Your machine has a T2 chip, so that also controls power on, so in rare cases ...
