How does the Maintenance
module help me?

When we say optimize your Mac, we don’t just mean cleaning up space — we mean optimize. You know, improving its efficiency of retrieval or processing (thanks dictionary). The Maintenance module gives you access to all sorts of Mac optimizing goodies.

Run Maintenance Scripts

When you run maintenance scripts with CleanMyMac 3, you help improve the performance of your Mac by removing and rotating old log files, rebuilding and reorganizing select databases on your Mac, and running other general maintenance tasks. It makes all the complex-sounding stuff simple.

Repair Disk Permissions

Verify and instantly repair broken permissions on your Mac’s operating system to help its performance. By repairing disk permissions, you ensure that your Mac’s system is functioning properly.

Verify Startup Disk

Verifying your startup disk is somewhat similar to Repair Disk Permissions. However, instead of your operating system, it checks your Mac’s file system for errors and repairs them to improve your system’s reading/writing performance and keep your Mac healthy.

Mail Speedup

When Mail gets to be overrun with messages, it can take forever to search for the stuff you need. You can sort all these messages out and fix the lag time by running Mail Speedup to reindex (read: re-organize) the Mail database.

Rebuild Launch Services Database

When you right-click a file in Finder and select “Open With…,” a list of applications is shown. However, if you’re installing and uninstalling applications, this list can become a bit muddled with apps you don’t even have anymore.

By rebuilding the Launch Services Database, you fix these default app associations, check and restore file icons, and solve other app-related issues.

Reindex Spotlight

Spotlight keeps track of all the names and locations of files on your Mac, including every word within the body of each of your documents and their metadata. Crazy, right? Reindexing Spotlight helps improve its searching performance and accuracy.

Flush DNS Cache

When your Mac accesses a website for the first time, it basically asks, “Hey, what’s the IP address for [website]?” The DNS (or Domain Name System) maps website names to IP addresses. For example, blog.macpaw.com to 174.142.192.113.

The memory of all these names and IP addresses is called the DNS Cache. Sometimes this cache becomes corrupt or out of date, resulting in you not being able to access a website. Flushing the DNS Cache can resolve this issue and others.
