However, I’ve found that installing rEFInd via a Linux session works just as well. The proper installation is demonstrated by this youtube video: rEFInd: How to Install and Boot Alternative OS on Mac. The file you want is the binary zip file found on the getting rEFInd from Sourceforge page via the rodsbooks website. The Catalina Patcher will allow the creation of install media (19H2) and the CatalinaOTAswufix will allow update to the latest version (19H524) after installation. Thread from macrumors: Catalina on Unsupported Macs.Links to run macOS Catalina on your Unsupported Mac: If you are going to dual boot / repartition you might as well bring that unsupported macBook up to a currently supported OS. help please.Personally I would not dual boot and just run Linux on that old mac but… Looks like no matter what, as soon as I install rEFIt i get a bogus 'Linux HD' option and somehow it prevents the real one 'Linux from partition 3' to work.Ĭan't figure out what's going on.

I could understand : 'Partition at LBA 430097144: Boot Code: GRUB' - that is the Linux partition where I told the installer to put the boot loader, but what is the other one ?Įven before installing Ubuntu rEFIt was giving me 2 options : 'Mac OS' and 'Linux HD'.Īfter installing Ubuntu (in the newly created /dev/sda3 partition) rEFIt gives me 3 options : 'Mac OS', 'Linux HD' and 'Linux from partition 3' ! Same result.Ĭan someone help me understand what is the meaning of : 'MBR contents: Boot Code: GRUB' I tried booting with rEFIt as well as by pressing the 'alt' key during the start up. Listed in MBR as partition 4, type 82 Linux swap / Solaris Listed in GPT as partition 4, type Linux Swap Listed in MBR as partition 3, type 83 Linux Listed in GPT as partition 3, type Basic Data Listed in MBR as partition 2, type af Mac OS X HFS+, active Listed in GPT as partition 2, type Mac OS X HFS+ Listed in GPT as partition 1, type EFI System (FAT) This is the partition info from Mac's Partition Inspector :Ĥ 608349420 625137344 82 Linux swap / Solarisīoot Code: None (Non-system disk message) Everything run smoothly but when trying to boot the Linux OS I get a black screen with a blinking cursor.

I asked the installer to put the boot loader in the Linux partition. Then in the Ubuntu installer, using GParted I created an ext4 partition for Linux and a Linux-swap partition. I installed rEFIt and and used Disk Utility to create a free space after the Mac HFS+ partition. I am trying to create a dual-boot setup on a MacBookPro 5,4 with OS X 10.6.7 and Ubuntu 10.04LTS 64bit.
