Apple's 21.5-inch iMac Late 2012 Series

We purchased this 21.5-inch iMac back in late 2012 when it originally released because we needed to tear it apart and make sure that Ramjet memory would work on this new mainboard with a upgraded Ivy Bridge Core i5 and i7 processor. Unlike prior iMacs, the 21.5 version (iMac13,1) is not user upgradeable for more RAM or internal SATA3 SSDs. It took THREE of us in the lab to put it all back together! 

A New Era in Non User-Upgradable iMacs

While we were excited to see the first wave of iMacs come with four new USB 3.0 ports and an optional Fusion Drive (SSD Hybrid), getting access to the mainboard proved to be almost impossible for any end-user. After we re-assembled this iMac, I inherited it as my office desktop. It came with 16GB of new Ramjet RAM and a 1TB 5400 RPM hard drive that we were unable to swap out with an internal SSD.

My Personal Experience Over Time

Within a year's time, I could tell that this iMac was slowing down. By mid 2014, I found myself using my Macbook Pro over this machine. It was just snappier. Soon, it became clear than I needed to find a way to revamp this machine and anything internal would not be possible. I created a mirror image of my Macintosh HD and booted from an external SSD.

It Was Like Night and Day

I was blown away by how much faster my new-old iMac became when I went with an external SSD. Not only was my iMac re-booting in a matter of seconds, it was also opening all of my files so much faster. A USB 3.0 port runs at a maximum throughput of 5Gbps and SATA3 SSDs top out at 6Gbps so I knew the external drive nor the cable could be a bottleneck. If you compare with Apple's 1TB 5400RPM hard drive, that was running at less than 1Gbps in comparison. 

The Ramjet Rugged Pro Lazarus Series

What can I say, it felt like I raised my old iMac from the dead. Hence the name. If you own a 21.5-inch iMac 13,1 (2012), iMac 14,1-14,3-14,4 (2013), or iMac 16,1-16,2 (2015), then your upgrade options are limited (to put it mildly). You may want to consider purchasing an external SSD from us and raise your Mac from the dead.

How to Boot Your Same System from an External SSD

Before you get started, be sure to make an external backup of your current Macintosh HD. If you have an extra hard drive lying around, you can easily plug it into one of our affordable docking stations for just $49.99.

Step 1 - Plug your new External SSD into one of your free USB 3.0 ports.
Step 2 - Download free cloning software onto your iMac.

Step 3 - Copy your Macintosh HD (internal hard drive) to your new External SSD. Be sure to select "Backup - all files" as that will ensure that you create a bootable clone. This may take a few hours to complete so be prepared not to use your iMac during this time.
Step 4 - Reboot your iMac like you normally would but when you see the Apple icon, hold down the Alt key until it provides you an option to boot from your SSD. Select your new SSD and if everything looks good but just faster, pat yourself on the back. 

Set Your New External SSD to Be Your Default

If you are loving your new-old iMac, then you can also set it to boot from this drive as a default. Simply go to System Preferences - Startup Disk and select your new SSD to be the system to start your computer.
