Macbook Pro Retina 13 2015 running slow after Mojave update

[Azamato]

Hey guys so I updated to Mojave like 4 days ago right? But ever since then my MBP is running so poorly.. everything is updated and all but Safari is stuttering so much when scrolling or youtube is buggering as well while I just randomly click around.. The same goes for finder. It looks like a 20 year old laptop now.. Is there anyway it can be solved or did i do something wrong? Anyone else with this issue?

Beyond Spotlight doing some initial work indexing all your files on a new OS install - which can slow it down a bit - you should not experience anything like what you describe.

May I wholeheartedly recommend that you do a clean install of Mojave – yes it does take more time and is a little more work - but your machine will perform beautifully afterwards. I do this for every single new MacOS.

Here's a guide (it is quite easy really, but does require some patience):
