1. Dr Cleaner For Mac

This how-to shows you the steps using Disk Utility 13 in OS X 10.10 Yosemite, but the process is the same if you’re using OS X 10.9 Mavericks or 10.8 Mountain Lion. Sometimes you want to wipe out all the data that’s on a hard drive or solid-state drive—erase it and start over.

The best way to do this is to format the drive, which both erases the drive and prepares it for storing data by mapping out bad sectors, creating address tables for locating the data on the disk, and more. Similarly, you may have purchased a new drive that was formatted for Windows out of the box. You'll want to reformat that drive for your Mac. But formatting a drive so that it can be used as your Mac’s startup drive requires a slightly different procedure than formatting it for use as a secondary drive for storing data. Click the Erase tab if it’s not already selected. At the bottom of the window, you’ll see some information about the drive you have selected.

Look at the Partition Map Scheme entry. If it says GUID Partition Table, you can format the drive by selecting Mac OS X Extended (Journaled) in the Format pop-up menu, giving the drive a name, and then clicking Erase. (Remember: This erases everything on the drive!) You can now skip directly to Step 8.

If the Partition Map Scheme says Master Boot Record or Apple Partition Map, you need to continue to step 5.

Apple's photo management software for the Mac, has grown to be a fairly competent all-purpose storage locker. But as your photo and video library grows — and especially if you've taken advantage of — you may find that your Photos library strains to fit on your Mac's hard drive. While there are options to keep your Mac from running out of space, like if you use iCloud Photo Library, it comes at a cost: Without a fully-stored Photos library, you won't be able to create secondary. (And as good as iCloud has become, your photos and video are precious enough that they're worth keeping backed up in multiple places.) There is an alternative: Moving your Photos library to an external drive (or creating an entirely separate library and syncing it with iCloud). Here's how to do it, and some reasons why you should — and shouldn't! — consider it for your needs.
