List of installation instructions, updated as I go along. I'm trying this on a 13" Macbook Pro Retina:
- Turn off OS X FileVault - encryption causes problems with rEFInd
- Use OS X Disk Utility to create an additional partition - create as free space. Size depends on how much you can spare - I used 60GB.
- Install rEFInd - this is a bootloader - a program that allows you to choose which operating system to use on reboot.
- Download Fedora 21 Workstation, and burn to DVD.
- Connect to Ethernet - WiFi does not work out of the box, so plug in a Thunderbolt Ethernet adaptor and use that for now.
- Reboot, and run Fedora from the DVD. Note, the DVD can take some time to spin up, so you may need to press ESC until you see it.
- [Reinstall rEFInd] - Not sure why this should be necessary, but when I rebooted after Fedora install, rEFInd did not appear. I had to boot to Apple's standard bootloader (press ALT whilst rebooting), go into OS X, and do step 3 again. rEFInd is now back, but I have several boot options. One is obvious (OS X), the Fedora next to it seems to be the easiest way to boot to Fedora. All a bit niggly, but usable.
Issue 1: WiFi doesn't work. This is basically down to Apple using a wireless card that does not support Free Software. Here are the steps needed to get it to work (which unfortunately requires some proprietary software):
- Enable RPMFusion free and nonfree packages.
- Install some packages to support the wireless card:
sudo yum install kernel-devel akmod-wl
sudo yum install wl
- Update all packages. I found I needed to do this in order to get the WiFi card recognised:
sudo yum update
- Firefox displays web pages a little small on a Retina display. Type about:config into the URL bar, then change layout.css.devPixelsPerPx to 2.
Apple Thunderbolt display: Works absolutely fine, no need for modifications. However, Fedora cannot handle the different DPI of this display and the laptop built-in display very well if both are being used - everything is too big on the external display. Only solution seems to be to disable the built-in display, which is fine as I don't use it with the Thunderbolt display anyway.
Apple wireless keyboard, and wireless trackpad: These work fine with Fedora, but the trackpad seems to have to be re-connected after each reboot (weirdly, the keyboard reconnects automatically). So lid has to be open on reboot so wireless trackpad can be reconnected. Also, they don't work with rEFInd, so you either have to reboot with the lid open or wait a while for the auto-selects.
Apple wireless keyboard mapping: Seems like some mappings e.g. ALT-3, which should be # on a British keyboard, are not working under Fedora. Will need to look into that.
Focusrite Scarlett 2i2: This is a pretty good USB audio device that I have plugged into the USB port on my Apple Thunderbolt display. It works fine with Fedora, no issues. Wow!
Next step: Power management. There are various reports that battery life sucks under Fedora. Under OS X I can get a full day's use on the battery. Wonder what will be achievable initially, and after some tweaking, with Fedora?
