Drive Eraser 6.1.2 and above.

Brief introduction to Apple machines:

Apple Inc. produce a large variety of machines including laptops, desktops, workstations, tablets, servers, mobile phones, watches, etc. These machines have different processors (laptops/desktops/workstations run PowerPC or Intel x86 processors, mobile phones and tablets run ARM-based processors, etc.) i.e. they require different erasure solutions:

If we focus on the Intel-based machines, they are often identified by family (MacBook, MacBook Air, MacBook Pro, iMac, …) and “model”:

Generalities on booting Apple machines:

Blancco Drive Eraser can be booted on Mac laptops and workstations, although in some cases the success of the procedure depends on the Mac model and involves some additional steps:

Handling some specific Apple models:

Some Apple machines (example models: MacBookPro11,1 with OWC Aura SSD, MacBookAir6,1 , MacBook9,1 , MacBook8,1 , MacBookAir7,1) contain drives (mainly ATA SSDs and NVMes) that do not implement any firmware-based erasure command required to perform a “purge-level” erasure (e.g. required if you use the erasure standards “NIST 800-88 Purge” or “Blancco SSD Erasure”). The problem lies in the drive firmware level where the required commands are missing:

Drive Eraser 7.x

With Drive Eraser 7.x Customized booting with a special parameters are recommended on all kind of Macbook models.

Recommended nooting parameters: archisobasedir=arch archisolabel=BLANCCO copytoram cow_spacesize=2G vmalloc=400M memtest=00 flr=disabled noapic nomodeset intremap=nosid

Customized booting option can be configured to a Drive Eraser .7x image with Drive Eraser Configuration tool.

Drive Eraser 6.x

Since 6.1.2, Blancco Drive Eraser has improved its support for newer Apple machines. Nevertheless, some models require the software to be booted with special booting parameters 1,2:

  • As a general recommendation, use preferably the booting option “FLR during startup”. If you use another booting option, make sure that the “splash” parameter is removed (if present).
    • Models successfully tested with this configuration: MacBookAir7,1 , MacBookAir7,2 , MacBookPro11,1 , MacBookPro11,4 , MacBookPro11,3
  • On some models, you need to add the "nomodeset" parameter (if missing).
    • Models successfully tested with this configuration: MacBookPro13,3
  • On some models, you need to add the "noapic" parameter.
    • Models successfully tested with this configuration: MacBook8,1 , iMac17,1 , MacPro6,1 , MacBookPro1,2
  • On some models, if you have troubles with the keyboard, touchpad or TouchBar, try adding the "intremap=nosid" parameter.
    • Models successfully tested with this configuration: MacBookPro13,3 , MacBook9,1
  • Keep in mind that some models need a combination of parameters.
    • As an example the iMac17,1 needs adding “noapic” and removing both “splash” and “nomodeset” (if present).

1: Adding/removing the default booting parameters can be automated if the software image is configured with Blancco Drive Eraser Configuration Tool 2.2 or higher. This can also be carried out manually, as explained below:

  1. Boot the machine, select the booting option (e.g. "FLR during startup"), press "e" to edit the option.
  2. With arrow keys, move the cursor down to the line starting with: "linux /arch/boot/x86_64/vmlinuz img_dev=..."
  3. Move the cursor after “$isofile” and add/remove the boot parameter(s) without quotes.
  4. Press Ctrl + "X" or F10 to continue booting.

2: Please note that newer Blancco Drive Eraser releases (post 6.1.2) may not require any special booting parameter to boot on these machines. Please test and fine-tune the booting parameters of any new Blancco Drive Eraser release before moving it to a Production environment.
