If you do the math relative to your hard driveвЂ™s size, youвЂ™ll understandВ how much photo libraries areВ weighing down your computer: theyВ were consuming aroundВ 1/4 of my iMacвЂ™s 1TB ofВ drive space. A window will pop up with a number, which in my MacвЂ™s case was over 236GB between a number of different photo libraries -В AppleвЂ™s Photo Booth, Aperture, iPhoto, and Photos, just to name a few. The simplest technique is to open a Finder window and right-click the Pictures folder under Favorites, choosing Get Info. If youвЂ™re not sure just how much space your photo collectionВ is consuming on your Mac, there are two ways to figure it out. IвЂ™ve usedВ both apps, as well as many others, and can help you choose the one thatвЂ™s best for your needsвЂ¦ ThatвЂ™s an incredible amount of wasted space attributable to duplicates, so itвЂ™s no surprise that a $1 utilityВ called Duplicate Photos Fixer ProВ has recently becomeВ the #1 paidВ Mac App Store app, whileВ a superior alternative called PhotoSweeperВ ($10) is in the top 50. After installingВ OS X 10.10.3, the new Photos app converted my 90GB Aperture library into a 126GB Photos library, and left both on my hard drive. Particularly after installing OS X 10.10.3 with AppleвЂ™s new Photos app, you might be surprised to learn thatВ youвЂ™ve lost a lot of hard drive space, and that there are suddenly tonsВ of duplicate photos on your Mac. TodayвЂ™s How-To is focused on something very specific but with a lot of optimization potential: trimming down your MacвЂ™s photo library. While youвЂ™re editing a photo or video, you can press the arrow keys to switch to other items.IвЂ™ve focused a lot over the last few months on helping readers to speed up and optimizeВ AppleвЂ™s Macs - everything from adding RAM to recovering hard drive space and upgrading old hard drives to faster SSDs.
