Chosen Solution
Hi all. I have been updating my late 2006 mac mini. Changed for an SSD, made an efi upgrade and added 4GB of RAM, changed CPU to a T7600. Succeeded in running OSX Lion smoothly. And tried to install El Capitan. It looks like it is installed properly but I can’t really tell, I can’t pass the password screen of the session : my bluetooth keyboard is not recognized because I didn’t have the chance to have it synchronized with this computer under this OS, and when I plugged a USB keyboard, I realized all USB ports are not running (they are are the beginning of the boot, but then not when the system loads). Any idea how I can fix this ? I have 2 OS installed in different partitions on the macmini : this El Capitan stuck and I can boot to a working Lion (if need to make changes to files in the El Capitan partition). Cheers.
Just an educated guess, but I am having a similar problem right now. Looks like the El Capitan goes to 64 bit processing instead of 32 bit. Here’s my issue but it’s on a machine that should take even High Sierra but it won’t go past Yosemite. My next try will be to take it down to 4 GB of RAM Kernel Panic with El Capitan and above
Please check here and there is some usb kexts
7a- We need kexts. We are using tones of kext from TMRJIJ - OS X Hackers (for example, Beta-USB-Kexts). To make things easy, you have them all zipped in this link: all-kexts. Download, unzip and copy them into /Volumes/Capitann/System/Library/Extensions/.
USB Issue using this method: You need to have something connected to one of the USBs when booting if you want El Capitan to detect USB devices. It can be a small USB stick, for example. http://osxhackers.net/elcapitan.html
