I use Linux Mint on my main laptop and that was all I had available.

I then turned to attempting to make a bootable USB stick of OS X El Capitan from an image downloaded from Apple. I also tried Internet Recovery (Command+Option+R) but that gave exactly the same error (and would also only have installed OS X Mountain Lion). The detailed error log says вЂњChunk validation failed, retryingвЂќ about 1000 times and eventually gives up altogether.ДЇurther investigation suggests this may be something to do with security certificates having expired and hence the machine not being able to download the necessary files from AppleвЂ™s servers, but it seems the error can appear for all sorts of reasons.

After about 30 seconds, a window pops up saying вЂњ CanвЂ™t download the additional components needed to install Mac OS XвЂќ and the installation gives up. I tried that with this machine, and upon hitting вЂњReinstall MacOS XвЂќ was greeted with a prompt telling me it would take -2,148,456,222 days and 8 hours (an uncaught buffer overflow, me thinks). Having recently fixed a busted MacBook Air I had learned a bit about Recovery Mode (hold Command+R whilst pushing the Power button and release a few seconds after the machine wakes up). Since there wasnвЂ™t much worth saving I wiped it and initiated recovery mode in order to re-install OS X (El Capitan). I was recently given a 2011 MacBook Pro that had been вЂњwell-lovedвЂќ and was therefore a mess of missing applications, ghost files and generally slow-as-hell.
