Once you’ve downloaded each app, look in your Mac’s Downloads folder (typically next to your Mac’s trash can on the desktop’s dock), click on OnyX.dmg and GrandPerspective-xxxx.dmg, and drag/drop each app icon into your Applications folder. (A paid alternative to OnyX, Cocktail by Maintain, offers similar functionality for $19.) Every version’s free, and very small, so you aren’t wasting storage space downloading whichever one you need. As they say, “There is a specific version of OnyX for each major version of the system. Use the specific version, and don’t try to use a non-compatible version.” When a new version of OS X comes out, just revisit the OnyX site and grab the latest release. Titanium offers individually optimized OnyX versions for every version of OS X from 10.2 to 10.10. Here’s the link to OnyX by Titanium Software.

(If you’d rather pay for a prettier and more frequently updated app that does the same thing, DaisyDisk from Software Ambience is $10 in the Mac App Store.) But the app still works perfectly under OS X Yosemite, and costs nothing. It’s not a beautiful web site, and my link will take you to the most recent version, which is several years old.

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.

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. “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.
