He told me that it had Mountain Lion on it when he got it and was upgraded to El Capitan. Suffice it to say that it's old enough to have a Spinning Hard Drive and DVD Drive on it. I told him to investigate a Catalina Upgrade. Anyway, consider this "situation" closed, because a Followup Question by me was about what other Hardware he has? He responded that he has an old Dell in a Closet with XP on it. We agreed that we leave alone the Mac, and make the Dell a "pure Debian Laptop". Thank you and best regards, Kenneth Parker

My friend didn't like my answer (don't use HFS+ for Linux) at all, putting the whole "project" in question. More on another reply. Thanks! Kenneth Parker

Mac El Capitan Dual Boot
I am helping a friend install Debian on an older MacBook, running OS X 10.11 (El Capitan). It currently has a single 300G HFS Plus (Journaled) Partition, with lots of free space. He wants to keep OS X, and use Buster (or Sid, leading to the next Stable Release). He wants to shrink the Mac Partition, create a couple more for this. (I explained the need for two, including a Swap Partition to him). He thinks that Debian should be able to work on the same HFS Plus Disk format. Has anyone tried this? This is all preliminary now, as I am trying to talk him into ext4 for the Debian Partition and, if he needs a place to share files, put a small, fourth vfat Partition in for that. Thanks in advance.
