We have some old Apples (2008/9 models) that have become troublesome to manage and were only ever being used as web browsers. So to rejuvenate them and make them into productive systems, we decided to give Cloudready from Neverware as go. This is essential a build of ChromeOS that you can install on a wide range of hardware and for a $15 licence fee you can enroll and manage as any other ChromeOS device. Installation is simple. Just follow the guide to make a bootable USB stick. Pop into your Apple, turn it on and boot to USB and it takes care of the rest. After installation, make sure you remove the stick before booting into ChromeOS for the first time. Video of one of our devices:
