macOS Big Sur very slow to open

By craxyorden27 ·

Hello !

I recently went from macOS High Sierra to macOS Big Sur on my Macbook Pro because I needed the update for some of my softwares.
https://showbox.tools/
Since the update, my mac is very slow to load the user session. https://speedtest.vet/

When starting my mac, it goes to the page where I can choose which session to load fairly quick. Then, when I choose my user session, it takes from 10 to 15 minutes to load, with the loading bar stopped half way.


Is this a known issue ? I can't seem to find a way to fix it.


Thank you.

Big Sur is a big beast

and lacking any information regarding your MBP I could guess at very low disk space, insufficient RAM or even just old age.
You'll probably say that it ran great under High Sierra but that was a much smaller and less demanding than Big Sur.
You skipped over two other MacOS versions and I wonder what software you have that demanded v11 (Big Sur) and not 10.15 (Catalina), remember you were two OS versions behind before you jumped to Big Sur.
A few specs on your MBP, RAM, HDD or SSD, Model, all found in "About this Mac" and how much room you have left on the drive would be helpful
Note Bob's subtle suggestion about a replacement SSD

Try to Clean it

Maybe your macOS has some malware that slows down your mac. Or your mac has various unnecessary files and app that is not in use, which also cover a big space in memory. So you need to remove these unwanted items from your mac.
