Mac slows down, how to optimize?

Question

macOS

Got a new poppy at work.
Filling:

From the applications used:

• Photoshop (3 open layouts with an average size of 20mb take 3.45g of memory)
  
• Chrome (usually up to 20 tabs open)
  
• phpstorm
  
• Messengers Viber, Telegram, Skype
  

At the moment, the memory is loaded up to 6.92g out of 8. The processor is not loaded.
The system freezes, it is uncomfortable to work. The simultaneous use of the storm and Photoshop is almost impossible, you have to either / or. Someone will say - "Chrome eats a lot, leave only the necessary tabs", and I do, but this does not always help.
The car is new, nothing extra was put.
Do all poppies suffer like this? )
How to optimize system performance?
It's worth CleanMyMac, freeing up memory helps for a while.
It also infuriates the periodic freezing of the cursor for 2-3 seconds.

Answer 1

1) Install an SSD if it's not worth it
2) Reinstall the system
3) Enjoy a fast Mac

Answer 2

I have the exact same iMac.
One conclusion was made, everything rests on a small amount of RAM.
I advise you to put two bars of 16GB each and forget about the problem for a couple of years at least.
Opera is inserted into this aimak in a very non-trivial way (you need to disassemble almost the entire body), but it is quite real.
32gb will change your life. And do not listen to those who talk about safari instead of chrome, I myself have a number of projects that do not work normally on safari, I have to use chrome. And in general, chrome can do a lot of things because of the extensions of what safari can't.

Answer 3

Do you have a 5400 screw? This is a bottleneck. Try plugging the ssd through the Sata-usb3 adapter, and put the Macos there.
If it gets better (and most likely it will) - you can think about disassembling the case and replacing it, adding trims, losing the warranty and all that. And you can work like that. Just don't forget to use the time machine

Answer 4

Photoshop (3 open layouts with an average size of 20mb each take 3.45g of memory)
Chrome (usually up to 20 tabs open)
PhpStorm
Messengers Viber, Telegram, Skype

Even if he did not slow down. Actually, a couple of Chrome tabs can lay down the system.

Answer 5

Mac drivers do not suffer.)
8 GB for this computer is very small, it does not have the best screw and integrated graphics. In general, for professional use, add another min 8 GB and you will be happy.

Answer 6

if kernel_task is loaded over 30% during freezing (in theory, it should go hundreds of percent at such moments), then this is mac os protection from overload ... They slow down the system themselves. Solved the problem with:

the kernel will keep looping some very simple tasks, eg getting the date, therefore 'consuming' (with the highest priority) the majority of the CPU in a bid to cool the system down.
The solution he mentions on his blog should work for earlier Macs. For Ivy-Bridge Macs and a little earlier Richard Schwarting has found the appropriate file to disable. Instructions are included below for convenience. I have tried many things, but this works.
Disable kext by renaming it
cd /System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/Plugins
sudo mv X86PlatformShim.kext X86PlatformShim.kext.disabled
Clear kext cache (not sure if this is needed)
sudo touch /System/Library/Extensions/
Restart
sudo reboot
After installing OSX updates you may need to repeat the above procedure if the updates have re-created the kext.

Answer 7

Slows down Mac

also news to me: D
you can try replacing chrome with opera or safari, and in the storm mark some directories as excluded (especially all sorts of node_modules and directories with assets that are collected by all sorts of webpacks with monitoring changes, etc.) - the storm is constantly trying to index them and hangs the system well.
