Mac Optimization FAQ

How can I make my Mac run faster with MacKeeper?

The following steps may optimize the speed of your Mac:

1. Save progress in all applications that you have active documents opened in (Microsoft Office, Apple Keynote, Numbers, Pages). Click the Apple logo in the upper left corner of the screen, and select Force Quit..., highlight applications one by one (all of them except Finder and MacKeeper), and select Force Quit.

2. Run MacKeeper's Safe Cleanup and remove all the junk files

3. Remove all the unnecessary items listed on MacKeeper's Login Items list. This is the way they slow down your Mac startup time.

4. Run MacKeeper's Memory Cleaner tool, and clear your memory on the Memory Usage tab

5. Run MacKeeper’s Duplicates Finder, delete the items detected by clicking Remove Duplicates

6. Restart your Mac: click the Apple logo and select Restart

How can I update my applications?

MacKeeper's Update Tracker checks each application installed on your Mac for the newest version available. To find the latest updates for your apps, do the following:

Step 1. Open MacKeeper, and select Update Tracker from the left sidebar.

Step 2. Next, click the blue Scan for Updates button.

Step 3. Select checkboxes for apps you want to update and click the blue Update button.

Step 4. If you want to install all updates MacKeeper found, click the blue Update All button.

I don't want applications to start up automatically once I turn on my Mac. What can I do?

The Login Items tool helps you control startup programs on your Mac quickly and easily. Removing startup items can help your macOS load faster because it won’t waste resources on loading unnecessary apps:

Step 1. Open MacKeeper, select Login Items from the left sidebar, and click Start Scan.

Step 2. Select the items you don't want to launch during the startup. Be careful though, ignore the items with a lock sign.

Step 3. Hit the blue Remove button at the bottom of the screen.
