This is (hopefully) an easy, step-by-step tutorial for installing OSX10.9 (and other Operating Systems) on your M6300. <UPDATE: I was able to update to 10.9.3 just fine after this installation.>
There’s not too much original information here, as it’s all been regurgitated from borrowed ideas in other posts and advice in forums everywhere.
A special THANK YOU to Sergeant for his advice and files that got me started on the right path for this!
Note: The attachments are a PDF with the step-by-step instructions and the files necessary to add to your OSX Installation Boot USB.
Post Install 1: I followed the advice in another post here about the running myHack's myFix to fix the sleep issue. My PC does wake up, but sadly my screen remains black ... However, a nice "side-effect" from running myFix is that my internal WiFi is now working! Yay!
Post Install 2: I've just updated this to 10.9.3 and then immediately (before the reboot) ran myHack's myFix (full). Everything booted up happy happy.
