Doesn't work on my machine. "Secure Boot violation. Invalid signature." I tried following manuals but no clue where to get the shim downloads for Linux MInt. I have secure boot enabled and dual boot with windows 11.
rEFInd is indispensible to set up your Mac to dual boot Linux Mint and MacOS and probably also awesome to select from multiple EFI boot loaders on your Linux box. I wanted to install Linux Mint on an old Macmini (mid-2010) so that if my Linux box failed for some reason and I couldn't get it running, I would have another computer running Linux Mint that I know and love that I could use until I could get my Linux box up and running again. While the Mac provides bootcamp to set up your Mac to dual boot Windows and MacOS, it provides no support to set it up to dual boot Linux and MacOS. To do this, the rEFInd boot manager (which selects a boot loader for each OS) is wonderful. The website for rEFInd has a lot of information and I found that rEFInd was meticulously written and covers the many versions of MacOS. You will probably need to disable MacOS SIP to successfully run rEFInd, and then re-enable it on the Mac. The zip archive that you download from the rEFInd website to your Mac also contains a very useful utility: refind-mkdefault which makes rEFInd the default boot manager and is a lot easier to use than efibootmgr.
