Q: What are the dangers of resetting PRAM and SMC on MacBook Pro

In our Mac deployment, we are having to do the COPR procedure an awful lot because the machines won't boot up normally. They are getting stuck about half-way and this appears to be the only way to get it moving again. We are sometimes doing a SMC reset in addition. We are currently researching a link between this problem, Yosemite and Active Directory.

 

What are the long-term effects of having to do these two resets repeatedly?

MacBook Air, OS X Yosemite (10.10.1)

    When you go thru the boot process, the macbook air does a check of things, Memory, startup volume, startup items and a verification of the startup volume among some other things. If it gets stuck and SMC and pram resets have to be done continually. You need to startup in recovery And use the disk utility option to check and repair the startup volume and permissions. If you find problems that disk utility can't repair, then you would have to try and reinstall from the recovery partition. Command R or Option R gets you there. You could also have a startup item that is corrupt or and out dated or incompatible app.
