maintenance scripts in Yosemite: necessary?

[jchuzi]

I shut down my computer overnight and sleep it when it's not being actively used at other times. AFAIK, the monthly, weekly and daily maintenance scripts don't run automatically because of this. I can run them manually, but how necessary are they in Yosemite?

I feel like running them when things slow down with the computer; isn't as often with the desktop at work, more often with the Macbook Pro I carry
around all the time.

This FineTunedMac thread seems to answer the question.

I realize that by running the automatic stuff in Onyx I don't always know what fixes something that's hanging; but it usually speeds things up or fixes them.

I used to believe Apple when they said the Unix scripts would run when it was determined that they had not run at their normal, O'Dark-Thirty times. However, I occasionally would fine that there was more than a day/week/month from the last log entry. I suppose a check tomorrow might be in order, things may have improved since I last checked. I'm not sure I can attribute any problem created by out-a-date "maintenance" runs.

I just had a weird thing happen with my work Macpro: I logged into it and ran iTunes and it went to the login screen again and required me to login again.  I'm not saying running the scripts fixed it; all
I know is it hasn't done it again.
