Is it better to shut down your rMBP every night, leave it on 24/7 or put it to sleep?

So my question is: how harmful is leaving the minister on 24/7

 

[Akira1980]

I have been keeping it on 24/7 for last 10 years of my usage. I only have display go to sleep after 10min. Only time I turn it off is when I notice slow down of OS or if Apps keep crashing.

I always close my lid therefore goes to sleep always. Only when i'm traveling long haul will i perhaps turn it off.

Show me what Apple Engineers say, and maybe I'll rethink my decision.

The Apple engineers who gave us Sleep Mode you mean?

For those interested, Apple's warnings about sleep mode are listed here:

About Energy Saver sleep and idle modes in Mac OS X

(there aren't any)

We have an rMBP and an MBA and only time we power off is when traveling. Just close the lid at night and all is well.

I only ever shut down my MBP if there is an OS update or something has caused me to feel a need for a reboot. When I'm done using it for the day it just gets the lid closed.

My Mini, that's on 24/7. Of course, when I leave home for extended periods, the Mini gets shut down, as does the MBP if I'm not taking it with me. The MBP also gets shut down if I AM taking it with me and I won't use it until I reach my destination (driving more than an hour or so).

I always turn mine off whenever I'm done using it. There's no reason for me to keep it running, sleep mode or not, all night.

I always sleep my Macs and have them last for years. I still have my 2008 black MacBook and it never got turned off. You will never shorten the life by sleeping a Mac. Even way back when I was using HP computers, I always just put them to sleep. I used to run a website on one of them and kept it on 24/7. After three years, I sold it when it was still working.

Until anyone can prove that sleeping the computer can harm it, I will never change.

NEVER?

Me too!

My brand new rMBP boots up literally in about 10 to 15 seconds. I know that's not as good as instant on, but I just always fully shut down at the end of the day. I guess what keeps me from putting it to sleep is that I don't know what that does to battery life. Something has to keep power flowing to the RAM to keep your session live, right? Or am I wrong about that?
