If you don’t get this warning, you can find Disk Utility at Applications/Utilities/Disk Utility.app You will likely get a dialog box stating that a drive is “unreadable.” Click the “Initialize” button to open Disk Utility.Restart your computer and boot to the internal hard drive like normal.Install your SSD in your Mac mini, following the instructions.

Make sure your data is backed up, just to be safe.

Perform the following steps in order to format your SSD and transfer your OS and data from your original drive. The preferred method is the “Internet Restore” method. If you are one of the affected Mac mini owners, then installing an SSD is a little different. If one or more of these factors are not involved, then you don’t have to worry, you can proceed as normal. If your installation involves all three factors, then you need to pay attention, as your installation will be affected.

You are adding an SSD to this Mac mini as a second drive, alongside the existing Hard Drive using an OWC Data Doubler Kit.

That 2012 Mac mini shipped with Mac OS X 10.8.2.

This particular instance affects you only if: It’s a bit of a “perfect storm,” but it’s worth noting if you’re adding an SSD as a second drive in your Mac mini. Let’s get into how to identify whether a Mac is a good candidate or not.The “Fusion Drive” option for the 2012 Mac minis can cause some severe data loss if you’re not careful. But, again, not all Macs need to be defragged.

There can be a few reasons why a Mac could be slow, but defragging may help. In general, it’s a good idea to defrag Macs or PCs with HDDs about once a month. Defragging also restores unusable capacity by reducing the space wasted between saved data. This unsystematic storage also creates spaces between saved data on the disk that aren’t usable, reducing storage capacity.ĭefragmenting basically reorders the data on the hard disk and bunches those bits together, making it faster and more efficient to access save files. This creates inefficiency, as the mechanical arm accessing a file must move to multiple sectors to collect the various bits of data a computer needs to read and open it. Over time, the data for a saved file becomes fragmented, meaning parts of the file are stored on different sectors of the disk. Hard disk drives (HDDs) store data on a spinning platter that’s divided into sectors.
