Hello, I have a mac pro late 2009 w/8 gigs ram more than 600 gig free drive space. My mac boots just like the pc mac has become. Lots of lag time, spinning ball, and the desktop loads like a dial up modem webpage. Again in pc style once the desktop arrives.... it's still not ready to do any thing. I have been wanting to scream this all over the internet ..... Why don't programmers know how much people hate that their computer is not ready to work when the desktop arrives? One line of code could delay the desktop till it's actually ready to do something. I can be the only person who feels this way. Even when it is ready to actually do something the web pages are slow to load. I remember when they came up INSTANTLY. I've been looking at `why is my mac running slow' videos. They are no help so far. Is mac cleaner software on the level. On activity monitor I see on reason for this. When I do all the disk utility stuff including boot to alt. drive and repair everything in site. Nothing changes. I ihave some free mac virus I got just to see if that was a problem, The software says no. It is Avira. I am not a computer wizz and went with mac because I don't have time to be a nerd. I just ran another virus scan and I'm clean according to Avira. So mac cleaner..... solution or problem? Thank you all for listening.
