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. -- George N. White III
