How to reinstall macOS from macOS Recovery.With your drive installed restart your system and hold the Option, Command (⌘) and R keys to enter into Internet Recovery making sure you have internet access via WiFi or better via Ethernet.
The first is to leverage internet recovery which if your system has the newer firmware should be able to gain access to it. There are a few different ways to do this.

If not, you’ll need to install a fresh OS. Hopefully you still have a bootable drive. While I’ve gone over the hardware side of things you still likely have corruptions on the drive. Using it to create the clean arcs where the cable needs to bend around the corners, its radius is as tight as you want the cable to bend. Instead find an old BIC ballpoint pen to get the ink straw out, we’ll use it as a forming brake. Don’t crease it! That damages the thin foil wires within the cable. The second is not damaging the cable in the process of installing it.

And here’s the guide to put it in MacBook Pro 13" Unibody Late 2011 Hard Drive Cable ReplacementĮven still we need to address two things besides replacing the cable, as you read in the link above we need to place a strip of electricians tape on the uppercase where the cable crosses over so you protect it from abrasion from the rough aluminum. So here’s the needed part MacBook Pro 13" Unibody (Mid 2012) Hard Drive Cable And yes this is a 2012 version of the cable which is the better one. Here’s a bit more on the details Your Hard Drive Cable Is A Ticking Time Bomb I think the title says it all!
#MAC OS X LION RELEASE DATE UPGRADE#
OK, let me explain… The Unibody MacBook Pro’s often need a new HD SATA cable and more so when you upgrade a HDD to a SSD.
If you didn’t altered your drive and only noted your system stopped working (you got the blinking question mark in a folder) Then you have in fact a hardware issues not software! Is there a strong reason why you are going this far back? While we can get around that using a different approach I think you’ve making this harder than it needs to be. Sadly Lion and Mountain Lion did not get updated. Here’s a bit more on it If you've got an old macOS install image, it will probably stop working todayĪpple did fix their blonder on the newest versions as they expired prematurely, reissuing Mojave back to El Capitan. Your hitting an Apple imposted brick wall! Apple puts an expiration date within its OS installers (certificate). i also removed one ram stick to have only 2 gb of ram.i also removed my hdd (replacing the optical reader) to make sure it does not interfere.Why is the system looking for files on the internet though it is launched via usb? This did not change anything…Īdditional info, collected on the internet: When trying the usb install, i ve shut down all internet connections. Same error message… As suggested in another post of the forum, I changed the date of the system (via terminal) to somewhere in 2012. But when I select it, and launch the install of the OS, the process is still looking for additionnal components, and therefore stops exactly like it did before with the internet recovery. I only have access to a PC to create the stick…Īfter several trials, I can now see the usb when pressing Option during the Mac start. I restored on the USB stick the file InstallESD.dmg (3,664 Ko). app file from a friend owning a Macbook Pro running Lion. So I created a bootable USB drive via TransMac, with a Lion OS. I tested my internet connection with the Safari help tool: internet works via Ethernet (command + D) Internet recovery didn’t work, I got the cannot download additional component error. My Macbook Pro 2011’s SSD disk is erased. I have been stuck for a couple of days and can’t find the solution…
