I have very slow boot times on iMac 2017 1TB fusion. After upgrading to Big Sur it's horrible. Nothing fixed it not even the new 11.1 update. I'm very frustrated because it is an expensive & professional machine
iMac 27″ 5K, macOS 11.1
After trying everything, the solution to the problem was to clean install and don't mess with Time Machine.
Big Sur messes up with the profile. So if you clean install and restore the profile, you restore also the slowness together with it. The best way is to just copy-paste all your files from a backup and install the apps from scratch. I did this and now my 27" 2017 1TB fusion iMac boots in 30 seconds!
Well I'm not going to debate you and btw I have over 40 years of skin in the game.
You should not debate me but my logic... It could perhaps help the Apple engineers solve this scandalous problem. It's totally unworthy of Apple.
This is NOT a chat forum, it is a technical forum to help solve problems. If you are looking for a chat forum there are many out there you can use.
You are, I am done with this thread.
My answer has just been censored. :-)
Oh, that's terrible. Saw your answer in my email though.
No, not for me and my 2 TB Fusion drive ; (
And let Apple know that we're not alone... https://forums.macrumors.com/threads/slow-booting-time.2268587/
Thank you, nothing to add!
Just recently updated to macOS Big Sur 11.2.1 and the slowness issue is still not solved.
Idem, 2105 128, from 10 sec boot time in Mojave or Catalina, up to almost a minute with Big Sour.
Apple, are you even reading your own discussion boards?
I'd call that an expensive work-around, not a fix of the problem...
Again, that is not normal. There is something else going on not with Big Sur.
Post if you want help.
But, your call. Good luck.
Unfortunately, safe mode did nothing for me.
And version 11.2.3 also doesn’t fix the issue. Still as slow as before here.
Same for mine. I wonder when the developer team will fix this fundamental issue...
Well, I spoke too fast... After that last 11.2.3 installation, my startup time has doubled (30s) versus 11.2.2 (15s)!
I give up ; (
Very slow boot on Fusion and Big Sur
