![]() ![]() The pictures above show how this is done: after you get the warning dialog, go to the Apple menu, pick System Preferences, select the Security & Privacy icon, and hit the Open Anyway button. ![]() Instead, you should manually authorize each “unidentified developer” app the first time it launches. In the name of security (and popularizing the Mac App Store), Apple introduced a new dialog box several years ago, warning users the first time they click on an app from “an unidentified developer.” This warning has probably stopped some people from opening malware, but it also blocks completely safe apps by trustworthy developers who haven’t sought Apple’s approval.įor most people, the right solution isn’t to disable this security feature. Step One: Don’t Be Surprised By This OS X Warning GrandPerspective offers a highly visual display of what’s taking up space on your Mac Onyx cleans up the Mac files you’d be afraid to touch yourself… Below, I’ll show you how two completely free Mac programs, GrandPerspective and OnyX, will do all the heavy lifting for you. Next, cleanse the cruft OS X builds up in the background as you use your computer. First, find and delete enough files to leave your Mac at least 50GB of free storage capacity - enough room for the Mac to work without pausing to manage its hard drive space. This How-To article offers a simpler alternative. That’s not as hard as it sounds, but it’s a radical and fairly time-consuming solution. Even die-hard Apple fans will admit that Macs typically run new OS X versions better (faster, and with fewer bugs) if you start with a clean slate: completely wipe your hard drive, do a fresh install of the latest OS X release, and restore only the files you need. I’ve devoted several columns to hardware solutions - replacing old hard drives with fast new SSDs, adding more RAM, and increasing storage capacity using an external drive - but there are software solutions, too. I don't think you will be disappointed.“My Mac used to be fast, but now it’s running so slow.” I’ve heard many versions of this complaint, and they’re always factually true, not just opinions: Macs do become sluggish over time, even if all of their chips and hard drives are working like new. When you hover over a box, the interface tells you what the path is, how big the file is, etc.Īnyway, Grand Perspective is a great little program that does it job well. Wow, that one app is bigger than I thought. The size of the little boxes represents the size of the files. The smaller boxes are the folders or files on the disk. Often it is a folder that needs a little more scrutiny. The app presents the user with a large rectangular box which respresents the container that is being analyzed. ![]() ![]() And it is solid now: I haven't had any trouble in years and years. Now the app is a simple, solid tool, that I only use occasionally, but it absolutely indespensible when I need it. In the early days, there were a few bugs, and I mention this only because the app was so useful, one would put up with a few crashes because Grand Perspective was still the best way to get the job done. In all this time, it has been the best way to figure out what is filling up a disk. I have used this app for many years on various Macs with various versions of Mac OS X.
