How to Cleanup Systems w/o CleanMyMac (a.k.a. OS X Cleanup Guide)

Here’re some folders you should check if you want to cleanup your Mac, all the following folders are also frequently scanned by CleanMyMac. Check and remember these then you won’t need CleanMyMac anymore.

Cache Files

All cache files can be deleted, but there’s no need to remove them too often, Homebrew uses the system cache folder to cache libraries.



All logs can be deleted safely.


Internet Plugins

Some of them are default from OS X. Check the bundle .plist to see if they’re shipped by default. In most cases, your user plugins folder shouldn’t be existed, most of them in this folder can be safely removed. AdobeAAMDetect.plugin is stored in system plugins forder.

/Library/Internet Plug-Ins/
~/Library/Internet Plug-Ins/

Launch Agents

All files in these folders are safe to delete. I have com.adobe.AAM.Updater-1.0.plist and com.adobe.AdobeCreativeCloud.plist stored in the system launch agents folder, they can be safely deleted.


Launch Daemons

Some apps stored their daemons app here, such as Clean My Mac and Textmate. They’re safe to delete. There’s no user launch daemons folder by default.


Privileged Helper Tools

Some apps uses privileged helpers to gain more access across different users from your Mac. For example I have com.macpaw.CleanMyMac2.Agent and com.macromates.auth_server in the following folder.


QuickLook Plugins

There’re two default plugins related to iBooks Author and iWork in system QuickLook folder, my user QuickLook folder is empty.


Spotlight Plugins

There’re iBooks Author and iWork plugins, too, plus a Microsoft Office Spotlight plugin shipped with OS X (10.9). My user Spotlight folder is empty.
