Getting Linux running on your Mac

My ideal scenario would of course be to select either macOS or Linux via the alt-Key in Apple's standard bootloader. David Anderson made a post about this which seems really appealing to me, nonetheless I am a bit sceptical because there are no reviews or answers to his method not questioning his competence and most people recommend using rEFInd anyways.

I am certainly ok with that and I have read the relevant arcticles on Rod Smiths website, but since every new version of macOS especially since the integration of SIP in El Capitan appears to change the way it handles the booting process and the majority of articles regarding this subject is older than My biggest concern regarding rEFInd is the malfunctioning of the hibernation feature other users complain about.

As far as my knowledge goes by now, I am planning to:.

  • Linux Mint Forums;

  • Before you start....

I have read that installing rEFInd on the a seperate hfs partition would fix the hibernation issue. And which volume do I set for the bootloader installation? In another thread a user stated that since El Capitan we were better off installing not installing rEFInd on a seperate hfs, but without stating why. Additionally, a supportive argument for this statement is of course the fact that rEFInd installs itself on the standard EFI partition by default in its newer versions.

Even if would I do everything the default way including the risk of the hibernation issue , what are the correct partition choices while installing Ubuntu?

Do I need to define an new EFI system partition in this case, or not at all? As you may have noticed, I have many questions and I apologize in advance if this post seems confusing to you. I will appreciate any kind of help. You're running into the paradox of choice -- too many options on this matter are creating confusion. In reality, it's hard to say that any one option in this specific issue is really any better than any other option, except in fitting certain very specific goals, most of which you haven't mentioned any preferences on, except:.

In this case, the solution to which you linked makes sense, although I suspect it may be a little bit overly-complex in a couple of points.

You're still relying on separate boot loaders Apple's boot. This is, in some sense, a minor matter of terminology; but it's important to understand that boot managers are user interface tools whereas boot loaders load kernels into memory and execute them, since in some contexts this distinction is very important.

Unfortunately, people tend to be sloppy about this distinction. Yes, the ever-changing nature of macOS booting can be a problem. Although doing this is sometimes necessary, that's rarely the case today.

Re: Dual Boot problem Ubuntu/Mac OSX (Macbook Pro)

Broadly speaking, you're then left with two choices:. Note that GRUB is both a boot manager and a boot loader. This was a big problem a while back, but I haven't seen any recent complaints about it, so I believe that the current defaults in refind-install fix this problem.

  • NVMe Patches.

  • Install rEFInd;

It's possible to switch boot managers and loaders even after you've installed everything. Don't even put a filesystem on it initially. If this resolves the problem, great. If there's even a prompt for where to install the boot loader, it's ignored in EFI mode. It's also worth pointing out that, if you intend to use rEFInd and the EFI stub loader, you can launch the Ubuntu installer by booting into "try before installing" mode, open a Terminal window, and typing ubiquity -b. The -b option tells the installer to not install GRUB.

This will minimize the chance of a boot coup in the future, and it will prevent GRUB from running time-consuming scripts whenever the kernel is updated to modify its configuration files which you wouldn't be using if you're not including GRUB in the boot process. I should also point out that I don't see the point of creating a second ESP in the instructions to which you've linked.

Maybe I'm missing something, though. There's just little or no point to doing so. Since this whole process can take several hours to complete, if you have any data you care about on your macOS, you will have to make sure you have up-to-date, redundant, reliable backups of this data in order to avoid data loss. If all of your data is kept on a single disk, and something happens during the installation process, your data could be lost forever, so make sure that you have backed up your data to more than one location.

If you have several hundred gigabytes of data like I do, this will take several hours if you do not have a fast disk. If you avoid the Apple Store you can actually get them for a very reasonable price. Make sure to keep your encryption keys safe in a good password manager or you will have to start from scratch although linux creds can be reset trivially with a live disk. This will be referred to as the boot partition. Debian can be booted directly by rEFInd if we just tell it where to point to. When you attempt to repaid MacOS you will get This disk cannot be used to start up your computer.
