The first sector of the GUID Partition Table (GPT) disk contains is a Master Boot Record (MBR). With my recent purchase of Snow Leopard, I created a second partition to instal 10.

When I run Disk Utility, the 'HD'(name of Mac OS X partition) is grayed out. All i see on the site is 'coming soon', greyed out button no preorder, no pick up, no sold out, no out of stock. What you are referring to is the boot code in the Master Boot Record of disk. The option to expand to fill the unallocated space is greyed out. The cable model number is written in white on your broken cable. Mac OS X has no boot loader in the traditional sense. Cables are NOT interchangeable since they come in entirely different lengths and won't fit right. There are 3-4 different cables for 2009, 2010, 2011, 2012 macbooks so get the right one. Fortunately it is easily purchasable for $10-25 on Amazon (as of 2021) and was pretty easy to install with only a small philips screw driver. Tape is not meant to hold the cable in place, it acts as a comfy bed for the cable.Īpple later made a thicker cable with a diferrent model number to address this issue.

The electrical tape backing is quite a slippery and smooth rubber surface. In the future, place electrical tape on the rough aluminum to reduce abrasion. The cable is the weakest link since it is sandwiched between your hot HDD/SSD and the rough brushed aluminium macbook. This cable's copper is fractured and transmitting data incorrectly making your Mac believe that it cannot find the boot HDD or SSD. The problem was the internal thin black flexible cable (less than 1 mm thick) that connects the drive to your Mac's motherboard. I thought my 8 year old OCZ Vertex 4 SSD was the culprit since my 10 year old Vertex 2 died in a Toshiba laptop. My Mid-2012 Macbook Pro 13" randomly stopped working due to this issue.
