Since the computer is running a fully operational clone, you can now download a free copy of Mac OS X 10.10.# from the Mac app store. Step 03: download a free copy of Mac OS from the Mac app store It really depends on the computer's hardware including the disk being wiped. If the dialogue appears simply confirm the action and forget about this for an estimated thirty-six hours. I assume since you are advanced enough to reinstall Mac OS you are also advanced enough to know about partitioning and what type of partition scheme Mac OS requires, which is selected by default as is the file system. As I recall, a warning dialogue appears which states the disk will be formatted and repartitioned. Navigate to and activate the Erase button located to the right of the Security Options button. If you wish to rename the volume Disk Utility is about to erase navigate to the text field which is to the left of the Erase Free Space button and enter what you wish. Navigate to and activate the Security Options button then move the slider to 100% and save the changes. You are using the clone so to destroy the source is okay.

Select the source disk вЂ“ NOT the source volume. The disks are always before the encompassed volumes. To the far left is a table of both the disks and volumes. To do this, launch Disk Utility which is located in the utilities folder. Seven is not foolproof but that is the maximum security setting permitted by Disk Utility

The remainder of what was still is if you or another knows how to recover the data. It is wholeheartedly recommended you wipe the hard disk because to simply reinstall Mac OS on a newly formatted disk does NOT make the installation any more вЂњcleanвЂ™ it only makes it so to both the user and operating system. The passes are unable to be customised or verified but it should suffice. Mine is 1.82 TiB so the entire task took days to complete. I could have used BCWipe but I chose to travel the easy route and use Disk Utility to perform a seven-pass wipe on the entire primary hard disk. Now that your fully operational bootable clone is just that вЂ“ fully operational, it is time to have some fun and give yourself some piece of mind. Step 02: boot from the clone and permanently destroy your primary operating system When the cloned operating system is ready for live production, test it because it will be what you will use for the next two days if you follow my process exactly as I explain it aside from the particularities of my Carbon Copy Cloner task schedule. I mentioned the Recovery HD partition above and the relevant setting for that is located on the General pane in the preferences window. That is how I do things and I know others вЂ“ especially average every day users will never delve nearly as deep into the software.

SafetyNet is off thus a deletion pass will be performed if required space is insufficient.

a full clone will be ensured with incremental updates every four hours.

The particular schedule I set up states the following: I personally use Mike Bombich's Carbon Copy Cloner to successfully accomplish this. By a clone I mean a fully working bootable clone complete with the Recovery HD partition.

If you do not wish to read this is not for you.Д«efore you do anything, it is wholeheartedly recommended you clone вЂ“ not back up, synchronise, copy et cetera the current iteration as it is of the primary operating system in use. Folks may disagree with some of it but thus far nobody has outlined their process. Below is an outline of the process I used with nothing but successful success. Reinstalling does some serious good for a machine in such a scenario. Sure, the user account was completely obliterated via Users and Groups, but the select lot of us know Mac OS's digital trails from yesteryear were clearly visible if one knew how and where to search. This late 2009 model iMac was provided to me last year thus it had five years of build-up including mine when I began to use it till I did what I will outline below. As the story begins, I did this on Sunday 05 April 2015.
