Many Mac hard drives break down and stop working. If you are upgrading or replacing a Mac hard drive and you don't have an operating system, this video will.
An Internet Recovery requires that you have qualified hardware: Computers that can be upgraded to use OS X Internet Recovery. If yours is qualified or can be with a firmware upgrade, then do the upgrade before proceeding.
Install OS X Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

Swapping out your old hard drive for a modern SSD is surprisingly affordable and results in 5X better performance: a reputable 500GB MacBook SSD can be had for around $150, while 1TB options are available for around $300 — both considerably cheaper than a new MacBook. It’s also surprisingly easy, even if you don’t know your way around the insides of a Mac.
Fitting a solid state drive in your MacBook Pro is a quick and simple way to boost performance but an upgrade might not always be needed.
If you only really use your Mac to browse the web and do some word processing, your current hard drive is probably fine. If your system feels a bit sluggish, try running CleanMyMac X first to clean away any resource-hogging junk. That might be the only fix you need (this way junk that is clogging up your system, such as old files, images, apps, duplicates and iPhone backups will be cleared away).
If, however, you’re noticing any of the following issues, an SSD upgrade will most certainly help:
To reap the benefits of an SSD, you need a drive that’s up to the task. Here’s what to consider:
Read/write speed — SSDs are rated on their reading and writing speed. The higher the speed, the better the performance. Something in the range of 500MB/s and above is good, although actual speed will be about a third less than what’s advertised.
Memory — MLC (multi-level cell) and SLC (single-level cell) are the two options available. The former is cheaper and capable of holding more information but the latter is more reliable.
Capacity — Get as much space as you can afford. The greater the capacity of an SSD, the more it will benefit Mac performance.
Reliability — Read the reviews. See what the experts and other users say about SSD performance and reliability. You’ll typically find that brand name SSDs rank the highest. Samsung, SanDisk, Crucial, KingSpec, and Transcend are standout brands.
Okay, let’s get down to business. SSD aside, here’s what you’ll need to fit your new hard drive:
Small Phillips screwdriver
Torx T6 screwdriver
To perform a MacBook Pro SSD upgrade you’re first going to need to clone your existing hard drive so that the new one runs like clockwork when it’s installed.
Before you do this, you should use CleanMyMac X to perform a Smart Cleanup. This will clear your system of any junk files so that they’re not transferred over unnecessarily. You can download CleanMyMac X for free, here.
Cloning the hard drive can be done with a tool such as SuperDuper! or Carbon Copy Cleaner, or with Apple’s own Disk Utility program. Here’s how to do it with the latter:
Now it’s time to get hands-on.
See, we told you it was easy!
A new SSD drive for your Mac will make an instant impact. Apps will launch faster, files will save quicker, and multitasking will be a much smoother experience. Use CleanMyMac X to regularly remove junk files from your system and you’ll enjoy slick performance for many a year to come.
CleanMyMac X finds and removes junk files from your MacBook Pro to free up space and keep your system running to its full potential. Make it the first app you install on your new SSD!
