Jun 24, 2015 I am rocking a base model 20' iMac Mid 2007 with upgraded Ram to 3GB, 320GB HDD, 2.4GHZ Core 2 Duo, ATI Radeon HD 2600 Pro with 256MB of memory. So this is basically the lowest spec machine (bar the extra gig over minimum of RAM) that will run El Capitan. Dec 10, 2017 The typical mid-2007 24-inch iMac featured a dual-core 2.4 GHz CPU and bus speed of 800 MHz (robust by 2007 standards, but sadly not today).

I decided to upgrade the CPU to a T9500 as well as installing a Sandisk SSD I had laying around. The results are fantastic.

iMac mid 2007 running El Capitan. When you try to boot in normal mode, the progress bar gets about half way across, and then the screen goes blank. It will boot into Recovery mode, and into Safe mode, but is very slow in Safe mode.
Run Disk Utility multiple times and it says there is nothing wrong with the disk. Re-installed El Capitan from download, reset NVRAM, still no joy. Customer did not have recent backup, but managed to copy user folder, and then restored from Time Machine backup from 2018. Still problems booting. There are multiple logs in /Library/Logs pointing to a problem with Windowserver, and looking at /var/log/system.log there are a lot of lines after GPU debug info. Any ideas? I can't get Hardware Diagnostics to start either with D or Option+D. Booting with Command+V to get log files shows it getting as far as networking, and then swaps to a blank gray screen El Capitan For Imac Mid 2007 MacCheck compatibility
