How-To: Safely shrink your Mac’s giant photo library, deleting duplicate images to save space
I’ve focused a lot over the last few months on helping readers to speed up and optimize Apple’s Macs — everything from adding RAM to recovering hard drive space and upgrading old hard drives to faster SSDs.
