Decided to experiment with Linux on this Mac. I was curious to see how “modern” I could make this Mac. I installed rEFInd first since I had seen it recommended in various guides online. The install went very well. I also erased the Lion partition and reformatted it as FAT32, per one of the guides I had read online. This left me with just Leopard, which I used to run the rEFInd install script. I then tried to make a bootable lubuntu USB flash drive/SD card because I don’t have any blank DVDs at the moment, but no matter what method I tried, the result was the same: an error message saying something along the lines of “Apple’s firmware has issues booting legacy OS’s from external hard drives.” I then burned an ISO of Ubuntu mini to a CD, but when I tried to boot from it, I got a different error message saying to insert a bootable disk.
I was about to give up when I remembered that I still had my DVD of Ubuntu 18.04 LTS (64-bit), which I made a couple years ago for my Lenovo Ideapad. I couldn’t boot from it at first, getting a message asking me to pick a CD-ROM boot type, but not being able to type anything. Looking around online I found a trick to get past this screen and continue to the installer. After selecting the DVD from the rEFInd boot screen and hitting enter, I held down the 1 key and hit enter a few times whenever the screen cuts to black. The first couple times I tried it, it didn’t work. I either ended up at the same message unable to go forward or I would accidentally skip past the main menu and end up at the Ubuntu desktop, but with no icons on screen. The Ubuntu desktop wouldn’t show up on the built-in display, so I had to hook up the MBP to my multi-sync monitor in order to even see the desktop. Sometimes I would get to the main menu, but I couldn’t use the keyboard. Somehow, after a few more attempts, I reached the main menu with the keyboard usable now. Having read that some users needed to use the nomodeset boot option to get things working correctly, I selected that option and then selected “install Ubuntu.” A few minutes later I was at the desktop and the icons were visible now (still needed to use the multi-sync monitor in order to see the desktop though). I ran the installer and Ubuntu installed successfully. I then hit restart and after exiting the desktop and the DVD being ejected, I got stuck at a purple screen with a blinking cursor. I waited about 10 minutes before giving up and doing a hard shutdown. I turned the Mac back on and saw that there were two entries for Ubuntu plus one for Leopard. I selected the second Ubuntu entry and was taken to the GRUB menu. While I was there I noticed that there were two Mac OS X entries, “Mac OS X(32 bit)” and “Mac OS X(64 bit)”, not sure why it’s like that. Anyway, I booted into Ubuntu from GRUB and was successful. I discovered that I didn’t need to use the multi-sync monitor anymore, I could use the built-in display now. I connected to the internet to run updates and then tested some programs out. The version of Firefox on here is 83 and it runs pretty well. In-browser YouTube playback is smooth at 360p. I discovered that the Discord desktop app works on here too as well as VLC. I edited GRUB to remove the nomodeset parameter and Ubuntu seems to be getting along fine with the Radeon GPU.
I’ve always been quite fond of Ubuntu 18. I used it for about a year or two on my Ideapad, but stopped using it because I needed Windows 10 for specific tasks and every time I booted Windows from GRUB, Windows would become very unstable. I had to change the boot order in my BIOS settings every time I wanted to use Windows 10. I am amazed that Ubuntu 18 runs on this Mac as well as it does. I have not tried booting OS X from GRUB, so I don’t know if OS X has the same problems as Windows 10 does with GRUB.
There are some downsides though. You need a two-button mouse to use the right-click menu (ctrl+click doesn’t work here). Screenshots have to be taken using the PrtSc key, which doesn’t exist on Mac keyboards, so you have to hookup a PC keyboard in order to take a screenshot. Ubuntu does feel a bit sluggish sometimes, which is to be expected given that I am running it on a 2006-vintage C2D. I ordered some blank DVD+Rs and I am thinking of trying lubuntu or Xubuntu and seeing how they perform on here. Ubuntu 18 is usable, but I am worried about how much system resources it is consuming given my Macs specs.
I do not plan on abandoning OS X for Linux, I just wanted to experiment with Linux on here and see how it did and it is doing pretty well.
