How to Recover files on Mac OS X Yosemite

Mac hard drive recovery can be tricky. The good news is, Disk Drill takes a complicated task and makes it simple. When you need to recover files from a Mac hard drive — either internal or external, Disk Drill can help you get your data back quickly. MacOS Big Sur Ready!
If you’ve upgraded to Apple’s OS X Yosemite, you may have lost critical files either during the upgrade or afterwards. In particular, some Mac users are reporting problems with lost Boot Camp Windows partitions after upgrading. And even worse, Time Machine does not typically back up files on Boot Camp partitions.

While losing data is always scary and frustrating, the good news is that Disk Drill is fully compatible with Yosemite (even the new Core Storage partition) and can help you find your lost data.

#1 Download and Install Disk Drill

If you are recovering from your Mac’s internal hard drive, then save the application to an external hard drive or USB flash drive, in order to avoid overwriting any data. To do this, download Disk Drill to your MacBook as you normally would from the CleverFiles website, double-click the disk image and then drag the Disk Drill icon to your external drive. If you are not recovering files from your internal hard drive, then you can drag the icon to your Applications folder.
