My brand new iMac "Late 2015" is SO SLOW. Why?

You’re trying to use computer hardware/software resource intense graphics apps like Adobe CC and Quark Xpress on a low end, base model iMac.

There isn’t much you can do about your situation.

Here's the BIG issues with all, but the topped out, 2013-2015, slimline, 21 inch screen iMac.

The 2013-2015 slim profile 21 inch screen iMacs that Apple had offered are, IMSO, "downgrades" from the previous 2009 thru 2011 21 inch iMacs models.

The 2013-2015 slim profile, "slimline", 21 inch screen model iMac are, basically, sealed up, glued up, basic computing appliances, now, with only the "top of the line" with all the top options (top i7 CPU, 16 GBs of RAM, 256 or 512 SSD) being the only viable option to use as a standard to medium professional grade, work related, iMac with just enough power for professional and creative use.

There is nothing in the 2013-2015, 21 inch screen iMacs the is user upgradeable OR serviceable, any longer.

Slower laptop 5400 RPM hard drive/fusion drives, limited RAM (the 2010, 2011 i5 CPU models and higher could take up to 32 GBs of RAM).

These 2012-2015 slimline 21 inch screen iMacs are limited to just 16 GBs of RAM.

Slower 5400 RPM laptop standard/style hard drives are 33% slower than the equivalent storage size in a "desktop standard" 7200 RPM hard drive.

This means 33% slower read/writes to the drive, in addition to other system delays.

Also, like laptop models, these older 2013-2015, 21 inch screen iMacs no longer use dedicated, discreet and independent GPUs.

These older slimline 21 inch screen iMacs use the "so-called" integrated (soldered) Intel Iris ”Pro" GPUs, now!

Meaning that in any of the newer 21 inch screen model iMacs, if you get one with the max 16 GBs of RAM, a little bit to quite a bit of that installed RAM is being used for the GPU's VRAM!

Meaning that the GPUs in these newer 21 inch screen model iMacs is stealing away physical RAM, for use by the GPU, for the GPU's VRAM, that could be needed for any other possible RAM intensive tasks depending on the apps being used or what combination of apps is being used together.

The GPU will automatically steal whatever the amount of physical RAM the the GPU needs for any type GPU related task.

This would not be as big an issue if you could install more than 16 GBs (which there is no way to do this in these 2013-2015 , 21 inch screen iMacs as Apple has soldered every single component to the logic board).

The 2012-2015 baseline 21 inch screen iMac models only come with 8 GBs of RAM standard.

New versions of the Mac OS need a base MINIMUM RAM of 8 GBs, now.

So, 8 GBs of RAM is really not enough RAM to run both the OS AND any additional applications.

Especially the type of applications that are SERIOUS hardware resource intensive!

To get a better performing iMac, now, you would have to spend the money for all of the top end options for the new 21 inch screen model iMacs to ensure better longevity and "futureproofing"

OR

You would really have to graduate up to the more expensive 27 inch screen iMacs that still have 7200 RPM hard drives/fusion drives, independent GPUs and user installable/upgradeable RAM.

I am NOT a big fan of these 2013-2015, 21 inch screen iMac models, at all!

Other than a top shelf version 21 inch screen model, the other 21 inch screen model options are like a Mac Mini with a screen, now, or like a laptop/desktop hybrid, sealed up appliance.

This is the only way to make these newer slimline, 21 inch screen iMacs faster.

To greatly improve the speed and performance of your 2013, 21 inch screen iMac, you are going to have to spend some significant more cash for this to happen.

My solution is to go the less difficult plug and play (somewhat) route.

Purchase an externally enclosed USB 3.0 or Thunderbolt connected large capacity SSD.

Format the SSD for Mac OS extended (journaled) with GUID partition scheme and then purchase data cloning software, like Bombich Software's CarbonCopyCloner or Shirt Pocket's SuperDuper to make a bootable clone of your current system to the SSD and boot and run your iMac, exclusively from the externally connected and enclosed SSD.

Your iMac will run A WHOLE LOT FASTER from an externally connected and enclosed SSD!

You can either opt to use your internal iMac's hard drive to just store data OR purchase, yet, another external USB 3.0 or Thunderbolt connected 7200 RPM mechanically spinning hard drive to use as your primary data storage and data backup.

If you are from the U.S., here is a good Mac/Apple source for external SSDs and standard 7200 RPM hard drives here.

https://eshop.macsales.com/shop/external-storage

You can call them to speak with a sales/technical rep or contact by email

RAM and GPU are still problematic in these 2013-2015, 21 inch screen iMacs, though.

There is nothing to be done with that!

You SHOULD BE running Photoshop alone with no other background apps running, when working exclusively and extensively with Photoshop.

You maybe able to run InDesign and Illustrator together (assuming that the file sizes in InDesign/Illustrator are unusually large) and if using Quark Xpress, you need to be just running one page layout app at a time with Adobe Illustrator

With only 8 GBs of RAM and with the iMac and the Mac OS using your iMac's available RAM, you really need to be using only one graphics app at a time when working exclusively in one of these graphics/drawing/photo/painting apps.

You’re iMac simply is underpowered for what you are using it for. Plain and simple.

Good Luck!

I have 21.5 inch 4K iMac from late 2015 with 1 TB fusion drive, 3.1 GHz i5, 8 GB.

It became exceptionally slow over the past year. I also had free Avira antivirus installed.

My hard drive was only half full. Checking on Activity Monitor my RAM was most of the time only 60-70% busy and always in the green zone.

I finally decided to deal with slowness. I cleaned up quite a lot cached files (In macOS High Sierra: About this Mac -> Storage -> Manage -> Documents -> File Browser tab), but it didn't help.

Then I decided to uninstall Avira antivirus. Suddenly the computer became much quicker and slowness disappeared!

I would highly recommend uninstalling any cleaning/antivirus software. Also clean up your hard drive from big cache files and any other unused files .

Hope this helps. As my RAM was running at around 60% most of the time, I don't think 8 GB RAM is an issue with these computers, unless your activity shows it's running full.

You need to completely rid your system of Kaspersky.

You still have all sorts of vestiges of Kaspersky infecting your system.

Uninstall it per the developer’s instructions.

Install more RAM.

You MUST use THE EXACT RAM that your model iMac is spec'd for.

and reliable Mac RAM can ONLY be purchased from online Mac RAM sources Crucial memory (crucial .com) or OWC, aka, Other World Computing (macsales.com).

When buying RAM for Macs from Crucial memory, purchase ONLY directly from the Crucial memory website. NOT from some other online source.

RAM modules are, relatively, easy to install.

Good Luck!

Remove/properly uninstall the Norton Antivirus software per the developer's instructions.

Uninstall CleanMyMac per the developer's instructions.

Get rid of the encryption and the VPN

macOS doesn’t need all of this!

macOS has always had great security and up to date versions of Safari are secure, also!

I do have the same problem with my mac

Thank you, you are really helpful. I don't live in the U.S. so unfortunately i can't shop anything from the store you told me. But this is not the case anyway!

I think the best solution is to format and shell this piece of s...!

The fault was mine, as i didn't know enough when i bought this machine.

Thanks again for your advices

The brand new 2017 21 inch iMac models are a quite a bit better, now, as they have RAM that can be expanded later on, but ONLY Apple can do this.

Apple has also returned the 2017, 21 inch screen models to having an independent, discreet GPU, now!

So, get an iMac with the most powerful GPU option you can afford.

Also, Apple is still sacking the 21 inch screen 2017 models with slow 5400 RPM hard drives/fusion drives.

If you purchase a new 2017, 21 inch screen iMac, forget the slow, mechanical spinning hard drives/fusion drive combos, and go straight for the SSD options (256 GBs, 512 GBs or 1 TB size SSDs).

Good Luck to you with any future iMac purchase!

Hello I have the same problem as others on this thread and I've just done the EtreCheck posted below. Any suggestions - apart from switching off Kaspersky?! (already done!) This iMac is a refurbished one from Apple (bought in July) and is still under warranty. Its so much slower than my previous 2009 27" iMac which is hugely disappointing. Any suggestions would be much appreciated. Thank you so much.

I have no clue, but you seem to have a lot of virtual disks that appear to be encrypted and the use of a VPN?

Why all the hyper security?

You work for some sort of government agency or something?

Paranoid much?

You are on the latest macOS with plenty of RAM.

You are running your Mac from an internal SSD.

This Mac should be blazing fast on an SSD!

I wonder if with the VPN and all the disk encryption is why your Mac is crashing and/or slow.

Macs don’t need all of this data encryption.

Security on the macOS is built-in and is pretty secure.

I can’t find any other issues that would cause this.

Don’t really see anything else that could be problematic, but that.

Don’t really know.

Good Luck!

Hi I'm having the same problem, my old imac got zapped by lightning last year and the insurance co replaced it with a new 2015 model, assuring me it would be just as fast, even though I expressed concerns it wouldnt be. Turns out I was right, its unbelievably slow at times! here's the Etre report in case you can shed any light? Thanks!

Problem description:

Beach ball all the time for simple tasks

Freezing on system upgrades

Generally poorer performance than my old 2009 imac (this new one is an unfortunate insurance replacement after old one got zapped by lightning)

Hi, I have the exact same iMac as Denmarkujin, and the same problem. Thanks for the useful information provided, in particular by MichelPM. Before I choose between the 2 solutions I get from the discussion here, i.e. buying an external SSD drive or just selling my iMac to buy a better model, could you please give me advice based on my EtreCheck Report?

I have the same problem.

It might have something to do with Dropbox

It takes 20 seconds to open a simple app or my preference panel.
