Using an OS X Mavericks Cache Cleaner to Make Mac Faster. You can further improve Mac performance in Mavericks by cleaning out the cache. The cache in Mavericks stores temporary information like the websites you’ve visited, videos you may have watched, etc. Over time, the cache can become larger than it should be and bog down performance.

Reinstall from macOS Recovery
macOS Recovery makes it easy to reinstall the Mac operating system, even if you need to erase your startup disk first. All you need is a connection to the Internet. If a wireless network is available, you can choose it from the Wi-Fi menu , which is also available in macOS Recovery.
1. Start up from macOS Recovery
To start up from macOS Recovery, turn on your Mac and immediately press and hold one of the following sets of keys on your keyboard. Release the keys when you see an Apple logo, spinning globe, or other startup screen.
Command (⌘)-R
Reinstall the latest macOS that was installed on your Mac (recommended).
Option-⌘-R
Upgrade to the latest macOS that is compatible with your Mac.
Shift-Option-⌘-R
Reinstall the macOS that came with your Mac, or the closest version still available.
You might be prompted to enter a password, such as a firmware password or the password of a user who is an administrator of this Mac. Enter the requested password to continue.
When you see the utilities window, you have started up from macOS Recovery.
2. Decide whether to erase (format) your disk

You probably don't need to erase, unless you're selling, trading in, or giving away your Mac, or you have an issue that requires you to erase. If you need to erase before installing macOS, select Disk Utility from the Utilities window, then click Continue. Learn more about when and how to erase.

- If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
- If the installer doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.

Mavericks Mac
Please allow installation to complete without putting your Mac to sleep or closing its lid. During installation, your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.
If your Mac restarts to a setup assistant, but you're selling, trading in, or giving away your Mac, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.
macOS Recovery exceptions
The version of macOS offered by macOS Recovery might vary in some cases:
![Mavericks Mavericks](/uploads/1/1/7/8/117802717/718117267.jpg)
- If macOS Sierra 10.12.4 or later has never been installed on this Mac, Option-Command-R installs the macOS that came with your Mac, or the closest version still available. And Shift-Option-Command-R isn't available.
- If you erased your entire disk instead of just the startup volume on that disk, macOS Recovery might offer only the macOS that came with your Mac, or the closest version still available. You can upgrade to a later version afterward.
- If your Mac has the Apple T2 Security Chip and you never installed a macOS update, Option-Command-R installs the latest macOS that was installed on your Mac.
- If you just had your Mac logic board replaced during a repair, macOS Recovery might offer only the latest macOS that is compatible with your Mac.
If you can't get macOS Recovery to offer the installer you want, you might be able to use one of the other ways to install macOS.
Other ways to install macOS

- You can also install macOS from the App Store or Software Update preferences. If you can't install macOS Catalina, you might be able to install an earlier macOS, such as macOS Mojave, High Sierra, Sierra, El Capitan, or Yosemite.
- Or create a bootable installer disk, then use that disk to install macOS on your Mac or another Mac.
M audio radium 49 driver for mac. One of the great things about OS X is that it basically runs itself. Left to its own devices Apple’s operating system will keep itself pretty clean and issue-free, but even with this there are times that you need to intervene to do some good old-fashioned manual maintenance.
The 5 tips outlined below can be done whenever your Mac is starting to run slower or if random issues start to pop up. You won’t hurt anything by running these actions, so if you’re experiencing any issues give them a try first.
1. Verify and Repair Permissions
Before going any farther, it’s probably a good idea to mention what exactly disk permissions are. Every file on your Mac has a set of permissions attached to it. These are basically settings that tell the operating system what users and application have access to each file. If permissions get out of whack you can experience issues with logging in, email, printing, or applications loading.
The first step is to verify disk permissions to see if it’s even worth repairing them. To do this go to Applications > Utilities > DiskUtility. From here, select the drive that OS X is installed on, then click Verify Disk Permissions.
If there are any issues in the history window like those seen in the example above, you would then click Repair Disk Permissions. This will get OS X going on realigning the permissions of system and application files so they run smoother and more reliably.
2. Verify and Repair Disk
If the problems with your Mac go beyond simple permissions issues, you may need to repair the disk. Just as with permissions you need to verify the disk first and if there are issues present you can repair it.
Repair Disk can fix any drive that is attached to your machine, but to run it on your startup disk you’ll need to boot into Recovery Mode or boot to an external install of OSX and run the command from there.
Repair Disk is most often done when a drive becomes unresponsive or data seems corrupted. It’s not often that you need to run Repair Disk on your startup disk, but it can help if you’re experiencing major issues. More on this can be found on Apple’s support page.

3. Running Maintenance Scripts
Your Mac is a UNIX-based system and as such it runs scheduled maintenance scripts to clean up logs and temporary files. By default these run between 3:15 and 5:30 in the morning. If your computer isn’t on or if its in sleep mode during this time the scripts never get run.
You can run them yourself however to make sure everything is clear and log files are rotated as planned. This is most easily done via Terminal. All you have to do is copy and paste this command into Terminal (Applications > Utilities > Terminal) and hit Enter:
sudo periodic daily weekly monthly
Enter your administrator password and the scripts will run. The daily, weekly, and monthly parts of that command refer to the specific log files it is clearing. You can run one of them or all of them, but unless you sift through log files regularly you might as well clear them all out. Here’s some more information on what these scripts do and how to see when they ran last.

4. Clean Your Desktop

Sometimes a clean desktop can do as much for speeding up your computer as all the other maintenance tips combined. Since OS X shows you a preview of every icon you can see, each one eats up a tiny bit of memory. Your desktop is also tied to the Finder, so a desktop full of icons can make your folder system run slower.
Move as many files as possible off of the desktop and organize them into folders. Not only will it help you organize your computer better, but it will help your speed, too.
5. Manage Login Items
Login items are the programs and files that load when you turn your Mac on.Having these out of control hurts you in two ways. First, this can dramatically affect the time it takes to start your Mac up and secondly these apps remain running after startup, so they slow you down even after startup.
To get Login items cleared up head over to System Preferences > Users & Groups. Select the user you want to look at (usually yourself) and click Login Items.
The Login Items page can be somewhat confusing at first. The check boxes you see to the left are not for running or not running the application. These are merely if the item is hidden or not after startup. To add or remove startup items click the lock and enter your admin password, then click the + or – buttons at the bottom of the window.

Remove any items you don’t want loading when your computer starts up. Ideally only leave items in here that are background applications like Dropbox or iTunesHelper. These need to run so their respective services operate as expected.

Wrap-Up
Macs are pretty great at “just working” so you don’t have to do a lot of maintenance to them. The heavier of a user you are, however, the more you have to check up on.
