How to delete some system files

Why you incessant little bumbling whootenanny you.....just who do you think you are ? turning off the juice whilst makin a clone.... how dare you !!!!!!

But seriously, you have succeeded in FUBARRING your clone......best to just wipe it clean & start over........just deleting the files, even if you could, will NOT fix the file system damage that occurred when the power went off.......

 

erase the partition in Disk Utility.

 

Terminal > rm -rf filename

 

Just to add, I think you need to "sudo rm -rf filename" for that since its a system file.

 

Hi All!

I have a similar problem - I have some locked system files in two of my old Time Machine backups on external hard drive. I was making a small cleaning and wanted to remove the old backups I don't need anymore. Everything went smooth except for bootX and boot.efi in system / library / core services.

These two files are listed in my actual system / library / core services now as well. What seems a bit odd to me is that a read privilege is awarded to someone called "wheel" and I have no idea who that is. Other read privilege is for "everyone" and the read / write for "system".

Either way, since those system files are backed up, I guess I can delete them, right?

thanks for help
