Yes, this may seem a bit tedious, but after installing a fresh 250GB SSD and with this Ubuntu 20.04 install procedure, our 2009 imac is running impressively well - almost too good to be true, really. Imac with Ubuntu (Lubuntu 20.04) - Controlling fan speed It looks pretty similar to what you tried, so I think maybe your problem is you didn't do step 1.įinally, I installed mbpfan so the fans were not always running on high, using the procedure in this post. So you skip the last steps in the post in #1 above, and instead follow this second procedure here: Help needed with Ubuntu 20.04 on iMac late 2009. For us, it was the NVIDIA "GeForce 9400". You need to install the proper NVIDIA drivers for the video card on your machine. One minor point is 3/4 of the way down the page, you need to add "sudo" to one of the lines: sudo mount -bind /dev /mnt/dev If you do it on an EFI partition, you will have all kinds of problems with the video card, even if you install the right drivers. You basically start with an EFI install procedure from the liveboot disk and then convert it to a BIOS one.
There is also a paid software called Parallels. I followed the "Option B" procedure in this post. As you already know, there are ways to install Windows 10 on a Mac. The first critical point is that the install must be done on a BIOS partition (not an EFI one).We have Ubuntu 20.04 working on a Late 2009 imac (in December 2021) and ran into these same kinds of issues but were able to successfully work through them.
