The Most Common Question We Get Asked

Why is it slow? How can I speed up my Mac? Why does my Mac take forever to load?

If we had a Pound coin for every time we got asked that we could probably buy a Mac Pro.

So as part of a FAQ series on iMendMacs we are going to help explain what’s wrong, & what you can do to make it better in the short term and even fix it long term.

Speed is subjective, you may not even notice your machine is slowing down, however, there is software out there to help identify any issues. This is the only time we shall mention 3rd party software, a lot of “Clean/Fix/Remover” software is generally Malware which could impact your security & won’t fix your Mac.

1. Speed up your Startup

One of the most noticeable parts of a slow Mac.

You walk into the office & power on your machine, & by the time you’ve made a brew it is still loading all your Application & windows.

Well, this is User Specific, however, if you don’t want that to always be the case, you can change some settings.

Firstly when you are Shutting your Machine down (Something you definitely should do, don’t just put it to sleep…see point 5) you get a prompt asking to “Reopen All Windows when logging back in” So EVERYTHING you have open will reload.

Useful if you carry on with tasks day to day, very annoying if you just want to start your browser & watch Netflix.

Firstly when you are shutting down, uncheck that checkbox & it will calm everything down on the next startup.

Secondly, you can edit what loads on startup when that checkbox is unticked.

You do this by going into , System Preferences, Users & Groups, Login Items. Use the minus (-) button at the bottom to remove the ones you don’t wish to load.

2: Restart your Mac

So people will advise you to “Delete Temporary Files” “Clear the Cache”

But you don’t need to do this, simply restart your computer.

Much like me & you, we all need a rest & recuperation.

By restarting your Mac it deletes the temporary files & clears the cache

Whilst we are here, you need to shut down your machine at LEAST once a week.

This will stop Wear & Tear & other components being in use when your machine is in Sleep Mode

3. Turn off Indexing

Indexing is how your Spotlight manages files in the background. Like having a personal assistant filing your documents away & remembering where they are.

It is very useful but if your Mac is running slow its a sacrifice you can make to get a little speed back.

You can select items to remove from indexing, so things you use/change more regular can stay switched on.

To turn off indexing , System Preferences, Spotlight & untick what you don’t need.

4. Put your Apps on a Fast, so your Mac Goes Faster

Some apps are hungry for memory, more so than other apps. If your Mac suddenly drops in speed, it is likely that a particular app is draining all of your memory and is bringing your Mac to a stand-still.

Thankfully, there is a way to find these data thieves and cancel out the culprits.

Enter… Activity monitor. Your new best friend!

To access it, use Spotlight search or the App is usually in the “Other” folder of your Applications.

Activity monitor monitors five different things… CPU, Memory, Energy, Disk, and Network usage.

If your Mac is running slow, the thing you want to focus on is CPU Usage. As you can see in the image below, you can select the CPU tab to view this particular data.

5. Upgrade, Replace, Refurbish

One of the best ways to speed up your Mac is to buy a new one. However, if you’ve spent upwards of £1000 on a Machine 2 years ago you shouldn’t have to spend more.

So you have 3 options. Upgrade the machine you have. Replace your Hard Drive or purchase a Refurbished Machine.


Older Machines have removable & upgradable RAM, the RAM is the Forklift truck of your machine, it takes the information & moves it around.

Much like a forklift, you can either have one with a Fiesta engine or a Ferrari engine.

The larger the GB the faster & more it can cope with.

If you wish to upgrade your RAM & don’t know what size you can have, Contact us.


Hard Drives wear out, over time, much like me & you. The more it works (Why you should shut it down not put it to sleep) the more it wears out.

So you should replace it with an SSD. An SSD is a Chipset, not a moveable part, so won’t wear out.

It’s THE best thing you can do to speed up your older machine, we’ve fitted them to machines that are 10 years old & they are faster & more reliable than they’ve ever been before.

We replace HDD’s with SSD’s pretty much 3 or 4 times a day if you want one get in touch.


Situations can change & the reason you use your Mac can also.

4 Years ago you might have been in School, now you might be a junior Graphic Designer, using Photoshop & Illustrator & your machine can’t keep up.

So pop along to our Refurb Store to see what machines we have to give you a spec bump.
