Q: Yosemite slow opening and cannot open itunes
Recently I upgraded the OS X to version 10.10.3 plus some supplemental update, and my itunes to version 12.1.12. To be more precise I installed the update on April 10th.
During the past week I have not used itunes, but when I tried to open that yesterday I failed. The icon does not even bounce, and no window comes out as usual. I did restart the machine, and I also followed some instruction online but none of them helped solve the problem.
Moreover, I discovered that after each update the speed of open my Mac pro becomes slower and slower. Now when I turn it on, usually the white apple icon appears instantly when I press the Power button, but now I have to wait for half a minutes with the black screen for the icon to come out.
So I am not sure if the update has problems. But now my main concern is how to make my itunes work??
MacBook Pro with Retina display, OS X Yosemite (10.10.3)

According to multiple reports on this site, Apple Support has given the following instructions to others who had a similar problem. I can't confirm that this procedure works or that it's necessary, but it won't leave you any worse off than you are now.
First, back up all data.
Select the iTunes icon in the Applications folder and open the Info window. Click the padlock icon in the lower right corner to unlock the settings.
In the Sharing & Permissions section, change the Privilege setting for each Name in the list to Read & Write. Close the window. If the settings aren't visible, click the disclosure triangle on the left so that it points down.
You should now be able to drag the iTunes application to the Trash and empty. Your iTunes data won't be affected.
Click the iTunes link at the top of this page, download the installer package and run it.
If iTunes still doesn't launch, or if you can't complete the procedure, reinstall the OS.
