Severe performance degradation vs Mavericks

What is showing as the top processes in Activity Monitor?

In CPU Usage: kernel task and WindowServer alternating..and also Firefox coming up and down.

Anyway..so you're telling Apple sells us bad stuff? Have you seen their actual MacBook Pro lineup? It starts with a 4GB RAM MBP..so..that one is a cursed one, you say? I cannot believe it. Also i'm running on an SSD here. And instead of a dual-core (as the MBP they sell), i have a quad-core i7. Come on!

No I am saying 4gb is a minimum for a reason. Its pretty cheap to upgrade, and to be honest it was the best money I ever spent as it revolutionised my machine. Also how much free space do you have?

One quick check would be to boot up in Safe Mode (hold down Shift whilst booting) - is the performance better? If so, perhaps something in your Login Items at startup is hogging cpu?

Memory can be a big bottleneck to the fastest processor - so another thought is an you see what apps are using the most memory in Activity Monitor as well - it may be a memory hog causing everything else to slow down

I tried everything on my mac pro:

-reset PRAM - nothing

-verify permissions on disk it found few problems all fixed, nothing helped

-I verified disk and no errors.

-I tried run in safe mode - I only get black screen with cursor and nothing happens. How long does it take to boot into safe mode?

I/m getting out of my mind... my mac pro performance is bad and this new system upgrade put my computer into useless state... 😟

Dear Nikolay

I have the same problem. I had installed Yosemite on my 2009 Macbook Pro with 4 GB RAM. Earlier, with the Mavericks, it was running quite fast, but after installing Yosemite, it has become very very slow. Almost unusable.

Did you find any solution to your problem.

I am unable to use my macbook like this.

Thanks

how do you boot in safe mode?

Try adjusting your Spotlight preferences.

"Luckily, Yosemite’s search-snooping can be switched off in seconds. In Mac OS X’s System Preferences, the functions can be found under “Spotlight” and then “Search Results.” From there you need to disable “Spotlight Suggestions,” “Bookmarks and History,” and “Bing Web Searches.” If you use Safari you will then need to disable the same “Spotlight Suggestions” function in the browser (under “Preferences” and then “Search”) to avoid having terms you type into its address bar shared with Apple by default too."

One benefit of disabling these things on my Yosemite test system was that it ran better. It was somewhat sluggsh before.

I have a Mac Pro with 2 AMD FirePro D500 video cards. I upgraded 2 weeks ago. Games do not load, crash, and are generally unplayable. Other applications are slow and frequently hang.
