This would make a fabulous Fedora workstation! However, I have had trouble
getting Fedora installer to run much at all.
I have an F38 install ISO dd'd to a thumb disk. On my Dell laptop, the
installer starts fine.
When I put the thumb disk on the iMac and hold <alt> during boot, I see "EFI
Boot" without issue., but every attempt I've tried to get it to boot or start
into the installer has failed.
There are some systems that won't boot the F38 installer. Workaround is to install
F37 and upgrade. With a bit of fiddling you can install Fedora to an external drive
with extra drivers so it runs on a variety of boxes.
Is there anybody here who has had success loading/running Fedora 37/38 on
Intel iMacs?
My wife's late 2012 iMac with the hybrid drive has a failed SSD, so she gave it to
me. I installed F36 and it has now been upgraded twice to F38. I installed Fedora
on a recycled 128 GB nvme SSD in a USB3 case. It boots 3x faster than using the
iMac's slow internal HD.
My model has an Nvidia GPU that Nvidia no longer supports (so will never support Wayland).
You can get a port of the Nvidia 470xx driver from rpmfusion-nonfree-release-38-1.noarch
(xorg-x11-drv-nvidia-470xx and akmod-nvidia-470xx). I did check that this installs without
Wayland or a text console support, so I'm using the nouveau driver with Wayland.
There is a "forever" bug in nouveau that triggers often under 6.2 kernels. A patch is in the works,
but I haven't had any issues, so maybe it isn't triggered on such old hardware.
There have been issues with wifi and sound, which is one reason it is nice to have a console
so I can see issues while booting. Having many years of experience installing linux on older
unused, unloved, and unwanted PC's, I have a 10base-T drop and keep some USB
sound devices and also a USB wifi dongle so I can ignore non-working network and sound
devices.
Before I retired I used a 27" Retina iMac that was excellent with macOS and Linux. The
current screen isn't as nice, but still excellent.
