A Mac with an extremely slow startup is arguably the worst and most exasperating of things to be faced with, particularly when you simply have to sit down and actually start work. The slow Mac boot and the reason you want to know how to fix slow boot mac is something that millions of Mac owners ask themselves on a daily basis. Fortunately for these million-or-so users and many more around the globe, almost every slow boot is actually quite a fixable problem that requires no specific or technical skills at all to resolve. The first and most important stage of fixing a slow Mac startup is discovering what the root cause of it is.

Reasons for a slow Mac boot include having too many applications open at login, a full hard drive, older Mac operating software, or even failing hardware. In this article, we will take a look at each and every reason for a slow Mac startup and provide detailed instructions so that the user can perform simple fixes to eradicate any lingering slowness at boot. Even if the Mac is relatively young at just 2 years old or somewhat older and is in its seventh year of service, being able to fix slow boot Mac will have an immediate positive effect on daily Mac usage.

Slow Boot Mac: How To Fix - Starting at the beginning

It is also best to check for the simple problems first before trying to go down a more complex fix path. It could be that an issue has only occurred quite recently, for instance, following an OS update, or possibly another peripheral that is conflicting.

Proper restart the Mac

When we put our Mac to sleep, rather than performing a shutdown, the processes do not clear themselves away fully. These tend to build up over time and will slow your Mac down as they take up precious processing power. A proper shutdown will give your Mac a clear slate.

Remove all external devices

Anything you have plugged into the Mac, from external hard drives and USB sticks to some types of monitors, will cause the Mac to try to boot off this, causing a delay in the boot process. Unplug everything other than the necessary hardware.

Update your Mac

Head into System Settings > General > Software Update. Running the latest available version of macOS is incredibly important for performance, as Apple rolls out patches that solve numerous small issues that can collectively impact your boot time, much like how managing tasks such as incognito history delete Chrome helps maintain overall system efficiency and privacy.

Get Rid of Login Items that are slowing down your start-up

If you want to find a quick fix for how to speed up Mac startup, look no further. Each and every application you have open when you log into your Mac all add to startup time, and every application you install often places an application in your login items that is unnoticeable and very often unnecessary.

If you are using macOS Ventura or newer, here’s how to get rid of login items:

1. Open system preferences

2. Navigate to General

3. Select Login Items and Extensions

4. Examine your "Open at Login" section, turn off any programs that do not require starting up when you first boot into your Mac.

Examples of such programs that appear on login items are Spotify, Slack, Dropbox, Google Drive, and Steam. These are very common applications that register a login item during the installation, and no warning is given. Getting rid of even three or four of these is one of the simplest ways to how to fix slow boot Mac and can cut down your boot time by nearly half.

If you are using older macOS versions (Monterey or earlier) you can find login items via system preferences by navigating through users and groups, selecting your username, and then login items, where you can see a list of applications to remove (press - for removing them.

The more discerning you are with these, the quicker the startup will be. Remember that although programs such as Dropbox, Google Drive, cloud storage applications, and Antivirus software need to start when your Mac starts, if, for example, you don’t use the Steam app regularly, then turning that off at startup is definitely going to help with boot speed.

Reclaim your Disk Space. This will accelerate boot time.

The obvious sign that your Mac's disk space is nearing capacity, when you can see the drive space remaining, is when it actually slows down a noticeable amount when starting up.  If you're trying to figure out how to fix slow boot Mac, a nearly full drive is one of the first things to check. MacOS needs some space available for writing temp files, virtual memory, and to load the OS up correctly. Simply filling up your drive with enough data could already explain why your startup is slow.

To reclaim your disk space:

1. Launch the Apple menu and open up System Settings (or Preferences, as it's called).

2. On the System settings panel, go to General, and then select Storage.

3. MacOS will then display the storage consumed by your Mac, broken down into various sections.

Here you can identify these locations that are taking up too much space:

●     Applications: Delete any applications you have not opened in months. Do not merely move to trash; make sure to delete them completely using the proper uninstall method or by dragging the application folder directly from Finder.

●     Documents and Downloads: It is highly probable that your downloads folder is where the largest storage consumption has gone unnoticed. Users tend to forget that they downloaded files. Sort them by file size, and you can quickly delete any data you have no use for.

●     System Data: This is somewhat harder to manage and stores caches and log files. You could use macOS built in 'Reduce clutter' option, or if you know how, you can go straight to the ~/Library/Caches folder and delete the contents inside all the subfolders, NOT the folders.

●     iCloud Optimization: Turn this on if you rely heavily on iCloud Drive.

Level up Your Storage: Swap the HDD for an SSD

If your Mac is over 5 years old, still has a traditional spinning hard disk drive, then it is the largest contributing factor as to why your machine is slow on boot up. This is particularly applicable for older 2015 to 2019 iMac and MacBook Pros, which were originally shipped with an HDD:

An SSD (solid-state drive) has no moving parts, which means it reads and writes data dramatically faster than a traditional hard drive. Replacing a HDD with an SSD on a compatible Mac can take how to fix slow boot Mac from over a minute down to under 15 seconds. The difference is that stark.

If this is not something that you feel confident doing yourself, any Apple Authorized Service Provider will carry out the process for you. On an older user-upgradeable Mac, there's arguably no better investment that you could make:

Reset the NVRAM and SMC

An often-overlooked solution to boot-up problems while learning about Mac fast boot issues is the reset NVRAM (Non-Volatile Random-Access Memory) and SMC (System Management Controller).

NVRAM Stores settings like:

●     The current resolution of your display

●     The disk that the computer boots from

●     The volume level, time zone, and more.

If the settings are corrupted, then the Mac might take time to determine how to boot up.

Reset NVRAM on Intel Macs:

●     Turn off the Mac.

●     Immediately press and hold the power button, and then press and hold: Option + Command + P + R.

●     Hold these keys for approximately 20 seconds while your Mac reboots, then release when your Mac chimes a second time or when the Apple logo appears and disappears a second time.

Reset the SMC on Intel Macs (non-T2 chip MacBooks):

●     Turn off the Mac.

●     Hold the Shift + Control + Option on the left side of the keyboard and the power button down simultaneously for about 10 seconds.

●     Release all of the keys, then turn the Mac on again using the power button.

Apple Silicon Macs (M1, M2, M3):

NVRAM gets reset every time your Mac is restarted, and you don’t need to do it manually. There is also no SMC on Apple Silicon Macs. You will only need to restart.

Add More RAM If Possible

 RAM is key to how fast your Mac boots up, and then how well it functions post-boot. The less RAM your Mac has, the more it uses something on your hard disk, known as swap memory, to keep itself running efficiently - which is one reason people look into how to fix slow boot Mac in the first place — the less efficient of the two..

For the older upgradeable Macs(the ones that have Intel chips), the RAM upgrade from 4GB to 8GB, or 8GB to 16GB, will help to improve their speed. To see if it needs RAM, you will need to find Activity Monitor under Applications>Utilities, then click Memory, and if memory pressure constantly says it's busy, you need to increase RAM.

 Macs with Apple Silicon use unified memory and cannot be upgraded once purchased, so when purchasing your new Mac, you should try to determine the RAM amount best suited for you.

Check processes with Activity Monitor

In many cases, it is a runaway application or background process that brings your Mac to its knees as it starts up. Activity Monitor will provide you with insight into exactly what is running and how many of your resources are being consumed.

Here’s how:

●     Open Activity Monitor from Applications and then Utilities

●     Go to the CPU tab and sort by % CPU

●     See if any particular processes are consistently taking a very large % CPU usage

●     You can select the process and then the 'X' button to force quit it, if necessary

Examples of culprits that might show up include stale browser extensions running on the back end, badly coded third-party applications, or stuck system processes looping infinitely. If a process with an unfamiliar name is guzzling up your resources, a quick search of its name should clear up whether you should go ahead and terminate it.

Conclusion

Even if it seems boring to find the reason for a slow startup, the solution is just a few clicks and maybe an hour away from most of the Mac users. Getting rid of unnecessary login items, flushing the cache, resetting NVRAM on your Mac, or fixing possible disk issues with the Disk Utility are common and very specific solutions to a slow booting process. "Fixing a slow Mac" is not a technical procedure that a beginner needs to know how to do.

It's about understanding what's ailing your machine and what you can do about it. Run through the solutions from top to bottom, and most will dramatically improve your boot time in under an hour.  If you're still stuck on how to fix slow boot Mac, upgrading to an SSD on an aging machine that still boots off an HDD is by far the most dramatic difference you can make. A tidy and streamlined Mac is a speedy Mac for years.

FAQS

Q1. How long should a Mac boot time be?

The time a well-working Mac should take to start up should be between 20 to 30 seconds. Any longer than a minute suggests there could be something else wrong.

Q2. How long can it take for a Mac to boot after an update?

The macOS update often involves index rebuilding or certain reconfigurations behind the scenes. Allow for about 30-60 minutes following a large update before concluding that something is wrong.

Q3. Does an abundance of browser tabs affect boot time?

While the presence of so many tabs doesn't necessarily increase boot time, it does affect how long the Mac stays slow following startup if your browser is configured to recover all previous tabs when it opens.

Q4. Does Mac malware affect boot time?

Yes, Mac malware does exist (not nearly as much as on Windows), and yes, malware can influence boot time. Rule this out using a current, reliable anti-malware scan.

Q5. Does restoring my Mac to factory settings help with slow boot times?

Factory resetting your Mac is almost certain to bring your machine back to an earlier, probably less bogged-down state, and will eliminate all the software conflicts that would be causing your slow boot-up.
