Slow login time

Hello,

since i've upgraded to Big Sur, my iMac is incredibly slow to log-in. It boot a little slower, but this is not an issue, however when i enter the user password it takes between 5 and 10 minutes to get a working desktop! It usually start without a black screen, then show the desktop image and the bar and then after minutes the icon on the desktop start to appear. Until the icons appear i cannot start anything, then performance are ok, a usual.

What can it be? I do not have many application at login, only drop box is shown in the login element, and the desktop is not on iCloud.

Any idea or help? I read about problems with usb devices, i have a logitech trackball, but unplugging it changed anything.

Thanks a lot!

iMac 21.5″, macOS 11.4

Go step by step and test.

1. Reset PRAM: Reset NVRAM or PRAM on your Mac - Apple Support

Settings that can be stored in NVRAM include sound volume, display resolution, startup-disk selection, time zone,

and recent kernel panic information.

The settings stored in NVRAM depend on your Mac and the devices that you're using with your Mac.

2. Reset SMC: How to reset the SMC of your Mac - Apple Support Choose the appropriate method.

Resetting the system management controller (SMC) can resolve certain issues related to power, battery, fans,

and other features.

3. Startup in Safe mode. https://support.apple.com/en-gb/HT201262 Choose the appropriate method.

To leave Safe Mode, choose “Restart” at the bottom.

Quote:

Safe mode prevents your Mac from loading certain software when it starts up, including login items,

system extensions not required by macOS,

and fonts not installed by macOS. It also does a basic check of your startup disk,

similar to using First Aid in Disk Utility.

And it deletes some system caches, including font caches and the kernel cache,

which will be created again automatically as needed.

4. Contact Apple.

Additionally, download and run Etrecheck. Etrecheck is a diagnostic tool that was developed by one of the most respected users here in the ASC and recommended by Apple Support to provide a snapshot of the system and help identify the more obvious culprits that can adversely affect a Mac's performance.

IMPORTANT:

Before running Etrecheck assign Full Disk Access to Etrecheck in the Etrecheck's Privacy preference pane so that it can get additional information from the Console and log files for the report:

Also click and read the About info to further permit full disk access.

Copy the report

and use the Additional Text button to include the report in your reply.

Then we can examine the report and see if we can determine what might be contributing to the problem.
