Give the Mac Finder a Performance Boost by Ditching “All My Files”
Though the All My Files folder is undoubtedly useful, Mac users with limited system resources along with tons of files may notice some sluggishness when using the feature. That can translate into CPU spikes and the perception of a generally slow Finder and Mac, because new windows in the file system default to opening into the “All My Files” view.
To better understand why the performance hit may happen, consider what All My Files is doing; it’s loading every single one of your personal files into a single smart folder, done by actively searching the file system for every document, picture, and media file that is owned by the active user account. Depending on your personal computer use, that can easily amount to 50,000+ items shown within a single folder which is updating live upon every modification of the file system. While some newer Macs with abundant system resources can do this with little impact on system performance, Macs with fewer available resources are usually he ones to notice the CPU spiking and slow refreshing of Finder windows and folders in OS X.
If you notice that opening new Finder windows is sluggish and you use All My Files, there are three fairly simple solutions to address the issue and boost Finder performance a bit.
1: Stop OS X Finder Defaulting to Opening New Windows Into “All My Files”
OS X has defaulted to opening new Finder windows into “All My Files” since the release of Lion, but from Lion through Mavericks you can easily change this and launch a new window into anything else. You can set it to the Home directory, which was the default in OS X for ages, the Desktop, or a folder of your choosing.
- From the Finder, pull down the ‘Finder’ window and choose “Finder Preferences”
- Under the “General” tab pull down the menu under “new Finder windows show:” and select the new default window destination
This speeds up the general experience of interacting with the Finder because new windows no longer have to refresh and show every single user file, instead they’ll just show what’s in the User Home directory, or elsewhere.
2: Choose To Use All My Files Selectively
Now that you don’t have the Finder opening new windows directly into All My Files, just get used to visiting it selectively, and only when it’s needed. The simplest way to do this by selecting it from the Finder window sidebar, say, when you want to get to your recently opened files:
This means you’ll only experience the (potentially) sluggish All My Files searching and redrawing when you want to, not every time you’re in the file system.
3: Close “All My Files” Windows When Finished Using Them
Regardless of when you’re using All My Files, remember to close the folder when you’re done using it. Because All My Files is not your average static folder, leaving it open causes the contents to redraw every time a user owned file is modified, copied, downloaded, or created, and that can cause CPU spikes and create substantial performance reduction if it’s just sitting there refreshing itself in the background while you go about other file system and computing activity.
The solution is so simple, use that little red button when you’re done with the folder! Don’t let it sit open in the background.
Varying Finder Performance Boosts for Old & New Macs
While new Macs may see a Finder performance boost from selectively using All My Files, this should be particularly helpful for Macs with a lot of files but fewer available resources, and used in conjunction with some other tips for speeding up older Macs you can really make a difference in how resource constrained machines perform.
It’s worth pointing out that while All My Files can cause CPU spikes when it’s being used or when it’s left open, it’s completely separate from the continuously high CPU usage problem of when the Finder process stays at 100% for no apparent reason, which is typically caused by a corrupted Finder plist file. That issue can occur on just about every Mac, usually after a system update has been installed.
