How To Make Your Mac Start Up Faster

Is your Mac taking forever to boot? Here’s how to speed it up.


We showed you how to speed up your Mac’s shut down process Mac Taking Too Long to Shut Down? 7 Tips and Fixes to Try Does your Mac take forever to shut down? Try these tips to troubleshoot slow macOS shutdowns. Read More , but for some reason we’ve never provided a list of ways to speed up boot. It turns out there are a bunch of things you can do to potentially speed the process along, starting out simple and working up to bigger things.

The ultimate fix is to boot OS X from a solid state drive 101 Guide To Solid State Drives Solid State Drives (SSDs) have really taken the mid-range to high end computing world by storm. But what are they? Read More , commonly called an SSD. We’ll get to that later in this list, but first let’s go over some of the more immediate ways you can potentially speed up your boot time.

Most of what we have outlined here shouldn’t cause data loss, but it’s better to be safe than sorry. Make sure you have a backup system for your Mac The Ultimate Triple Backup Solution For Your Mac [Mac OSX] As the developer here at MakeUseOf and as someone who earns their entire income from working online, it's fair to say my computer and data are quite important. They’re set up perfectly for productivity with... Read More , and that your backups are up-to-date, before trying anything outlined here.

Verify Your Hard Drive And Permissions

Scan for and fix hard drive issues that could be causing your boot to hang.

This is a simple thing to try first. Open Disk Utility, which you can find using Spotlight, or using the Finder by heading to Applications, then Utilities.



In the left panel you’ll see your hard drives. Click your boot partition, then click Verify Disk Partitions. If Disk Utility reports a problem, click Repair Disk Permissions. When that’s done, click Verify Disk to check for errors; again, if Disk Utility reports a problem, click “Repair Disk”.


Clear settings your Mac uses at startup, including incorrect ones that might be slowing you down.

If you hit “Mute” on your Mac and then restart it, you won’t hear the signature startup sound when it turns on.


How does your Mac know your Mac is muted, before the operating system starts up? Because of PRAM.

Your Mac has a special kind of memory called PRAM, or NVRAM on newer Macs. This memory is unlike other RAM as it is not cleared at power-off, and stores all kinds of settings like your system volume and designated startup disk.

Sometimes it’s looking for the wrong startup disk, however, and when that happens you should reset your Mac’s PRAM How to Do an SMC and PRAM/NVRAM Reset on Your Mac A reset of the SMC and PRAM/NVRAM can help any Mac, including MacBook Pro and MacBook Air, run smoothly again. Read More . Doing so is simple: first, turn off your Mac. Then, when you start it up, press Command, Option, P, and R keys at the same time.

Check Your Startup Apps & Login Items

Stop programs from automatically opening at boot, so they don’t slow down your startup.


Your Mac probably starts a few programs when you log in, which takes time. If you’d rather start these programs yourself later, head to System Preferences, click Users and Select your User, then hit the Login Items button.


Remove anything from this list that you don’t want to start at boot.

Some programs start before you log in – removing them takes a bit more work. Open Finder, then (in the menu bar at the top of the screen) click Go followed by Go To Folder. In the window that pops up, enter /Volumes/Macintosh HD/Library/StartupItems/



If your boot partition is called something besides “Macintosh HD”, use that instead.


You are now looking at the hidden folder that tells your Mac what applications to start at boot. If you recognize anything here you no longer have installed, delete the relevant folders.

One last thing: by default, your Mac will re-open programs at boot that you had open at shutdown. You can turn this off before shutting down, with a simple checkmark:


For a faster restart, make sure this box isn’t checked.

Free Up Space On Your Hard Drive

It’s unlikely, but insufficient free space on your boot drive can cause issues at boot. Delete a few things to speed things along.

If your startup disk is nearly full, it might be slowing down your boot time.

Delete Unused Fonts

Delete fonts you don’t use, so your Mac doesn’t need to initialise them at startup.

You can use Fontbook to manage fonts on your Mac Manage Your Fonts With The Fonts Panel & Font Book [Mac] Read More , and if your concerned about boot time it’s a good idea to clean this out from time to time.

Turn On Automatic Login

Login automatically, so you don’t have to type your password halfway through the startup process

This won’t necessarily speed up booting your Mac, but it does remove a step from the process. With automatic login turned on, you can walk away from your booting Mac until your system is completely ready to go, without the need to type your password halfway through the process. While there are security problems with this approach, it certainly speeds things up.


In System Preferences, click Users, then find the Login Options button at bottom-left. From here you can enable automatic login.

Reinstall OS X

If nothing seems to work, why not start over?

If your Mac still starts up slowly then the problem is your hardware.

Get An SSD For Really Fast Boot Times

The ultimate fix: replace your hard drive with a much faster SSD .

If you want your Mac to boot faster (and do just about everything else faster too), this is the single most powerful fix – a solid state drive.

All new MacBooks come with an SSD, and many newer iMacs and Mac mini also come with them (or a hybrid known as Fusion Drive What is Apple's Fusion Drive & How Does It Work? Solid state drives are awesome. The only snag is that solid state storage is still prohibitively expensive for storing lots of data. The days of cheap SSDs are probably not that far away, but for... Read More ). If your Mac isn’t one of them, though, you can replace your current drive with an SSD. The catch? Unless you have infinite funds, you’ll probably end up with less hard drive space. If you’re interested, this thread on Apple’s support forums has all the information you could possibly need.

    There's often a bunch of stuff in /Library/LaunchAgents /Library/LaunchDaemons and ditto ~/Library ... ( don't mess with /System/Library/Launch* unless you want to live dangerously). If there is stuff in those places that you really don't want then remove and reboot. \

    Awesome guide. For the cleaning part, one tip to add - the free app MacClean can do most of the cleaning jobs well and fast. It works great for me. Maybe you can have a try as well.
