how to erase mac before sending in for repair

Unfortunately, if it weren't for bad luck I wouldn't have any at all! I'm stuck with a Windows laptop until I get my Mac back, and I stupidly didn't think about that fact. So I think all my bases were covered and it's out for delivery as I'm typing I did end up finding something online that explained how to do it using Disk Utility, which did the trick in under a hour, and was able to update it too. I tried to drag-and-drop, which after almost three hours it had a file count over a million but still said it was preparing to move the files and none had actually been transferred.

The only real trouble I had was transferring my Time Machine backup to my new external hard drive. Otherwise it could take even longer, or worst case scenario they may have to replace my Mac altogetherīut I did get the CCC trial, which was so easy to use I thought I'd done something wrong the first time and started over LOL And also got File Vault enabled too. So I'm crossing my fingers no other damage was done, and they can get a new battery. Still not sure what happened, but something caused the battery to swell, and the base/keyboard was pillow-shaped. I could have rescheduled, but was told it would be at least two weeks before I get my Mac back, and that's best case scenario for a simple battery replacement. I couldn't have pulled this off on my own in the time I had, so thank you all!!

I apologize for the delay in posting an update, but I want to thank everyone for all the help.
