Reputable Mac maintenance software

My Mac (Yosemite) is excruciatingly slow. Could anyone recommend a reputable software or app to clean and maintain the machine?

Most of our members seem to like Onyx. It will take care of most of your needs.

Thank you for your effort, especially since you are not feeling well. I had this foolish idea, that forums are not necessarily for experts and veterans, but also for babes lost in the woods, like me.
I hope you get well soon. I'll pursue the issue to the best of my ability, although I believe that posting a permanent library of answers to most opften asked stupid questions is an excellent idea,

Thanks again.

It's not a stupid question at all Pustelnik38, and I was just a bit off with my hasty reply, but maybe a suggestion for similar posts.

I'm sure you'll get better replies, but in order to help them, maybe you could describe what exactly is "slow", and some details of your Mac like: RAM memory amount installed, free disk space, user prefs login items, Mac's age etc.

Please, think nothing of it. I am quite familiar with the mood you were in. I will get to work right away on gathering the requested info. I'll do my best to make it as clear and succinct as possible.
Thanks,

There are others But Oynx Is the way to go

How odd half the threads seem to be missing.

However, what model Mac, how much memory and how much free space is available on the hard drive? Did you do an upgrade to Yosemite and from what operating system, please?

Yes, there is a distinct feeling I'm missing something in this thread, regardless, here is a list of 9 possible reasons why a Mac may run slow and what to do about it;
