Installed the 24.04 LTS release of Ubuntu, Noble Numbat, on Macbook so it dual boots with Sonoma (itś actually a 10 year-old Macbook Pro using OCLP to enable latest version of OSX to run). The only part of getting Ubuntu to dual boot was the actual dual booting itself. All the resizing of partitions and installation of Ubuntu worked great but it just wouldn´t let me choose which OS when the Macboot started up… until I found this post on Tinker Different that gave pointers about how to get OCLP to play nicely with the Ubuntu EFI.
And it works.
My long-term plan is to move completely to Linux on the desktop (and to an Android phone) and beginning to use Noble Numbat as my main OS ongoing (well, Iĺl give it a month). Iḿ already impressed by how speedy the Macbook is running Linux and how good the Ubuntu UI is. Iǘe played with Linux distros before but never was able to get into them.
