Slow user switching

Problem solved. I'm back on Mojave and my iMac is again super fast and running smoothly. Userswitch is instant. Everything is great. I will not go to Catalina soon, as long as people continues reporting issues and they don't seem to be solved. Sad for Apple, they should do better.

CanukInAugusta, you obviously haven't read the entire thread as you've claimed. There have been MANY posts that the current Catalina beta resolves it....IN THIS THREAD! Even just read literally the very last post prior to yours!

I respectfully disagree the problem has not been fixed, unless you count yourself of the privileged class of Betafites. Until a complete publicly available update is published the problem remains just that a problem. Apple should never have released such buggy first generation OS, in years past they would never have published an OS this badly constructed. I have been a Mac person back to the Macintosh SE. Jobs RIP was at times a tyrant in his perfection, but he was right. If they had released this in the early days we would be calling MS Support today

So anyone knows when the official release will be? Besides the slow switching, the system is getting slower and slower. I just use iterm and a browser. If I run VLC for example, the system also dies for at least another 20 secs. My Macbook has 16GB Ram, i7 and SSD.

I've been with Apple a long time too, but I feel like you've either got a bad memory or have been exceptionally lucky over the years. New OS releases - both OS X, and iOS since that's been around - have been notoriously buggy in varying degrees over the years, and there was always the advice to wait until the third service release (.3) before installing. What's changed is that these days people mass upgrade on release day because it's free (remember back when you had to pay for OS upgrades?) and yay new features. Apple hasn't changed nearly as much as people think it has. Nothing feeds nostalgia more than a faulty memory.

Might be that VLC freezes my computer because some of the videos are encoded with OpenH264?

Anyway I do all the things I commented in my Zenbook, i3, 2GB of ram (2012). McBook Pro 2017 i7, 16GB Ram hangs and drinks the battery in around 3 hours.

Were you able to find a solution for this problem? I have the same issue, it also happens whenever I am trying to authenticate in system preferences. The authentication dialog takes about 10-15 seconds to appear. Everything else is blazing fast.

Late to this party, but thank you to all the bleeding edge users who help identify the early bugs, so those of us who prefer to wait for .2 iterations can live more sanely. ;-)

For those who get frustrated, join the beta party (so you can really experience bugs), or wait for an update or two BEFORE updating to a new OS, and only then after reading what kinds of issues you might run into when you do.

I also encourage folks to test upgrading with a backup version of their drive; in addition to a TimeMachine backup, I have an external SSD that is a clone of my internal, which is my quick safety net, letting me keep running easily if there is a problem with my main Mac. This can be upgraded as a test machine, with TimeMachine being my secondary safety net. But even then, don't rush into it blindly. For example, if you update Reminders, even on a clone, if you are iCloud connected, my understanding is you may not be able to go back. So you might even consider testing with a different iCloud account.

btw it doesn't happen in safe mode.

Try running the macOS Catalina 10.15.2 Combo Update and see if that fixes the problem as it has for others.

Did it continue when you rebooted normally?

Have you installed and run any "cleaning", "optimizing", "speed-up" or anti-virus apps?

Same issue here with 2018 Macbook Pro. Since full update to Catalina switching accounts is very slow.

Same problem, late 2014 mac mini

Sadly, today's supplemental update hasn't resolved the issue.
