I've always leave my computers running. My last PC has been on for a few years without being shut down. Any problem leaving Macs running all the time?

I leave my 09 (sig) on 24/7 (running headless) and my Macbook only sleeps when I close the lid. So I never really shut it off.

So keep it on.
 
I've always left my Minis running (or sleeping when inactive for awhile), no problems there.
 
Have only shut down my Mini for updates since purchasing it in July. No problems whatsoever.
 
My mini also runs headless 24/7.
They use next to nothing when in sleep mode anyway (electricity wise).
 
Always ON. Sleep mode ON too. Due to ML f-ck up with sleep mode I gotta use caffeinate though.

I usually do a reboot every 3/4 days too.
 
Since 23 hours of the day my mac mini would be idleing I shut it down. With the SSD it comes up so fast, that it doesn't matter to me.
 
Did you calculate how much cash you wasted on the electricity bill?
Turn it off. Any Mac boots within your first coffee.
 
No problems.....

to my knowledge when you have good ventilation, no voltage fluctuactions and no running intensive apps (read/writing to HDD, RAM intensive or processor intensive tasks)

like a washing machine, electric stove, power tool, table lamp, tv, stereo, guitar amp, etc, etc, i turn it on when its being used and turned off when its not

To answer your question literally, no, there is no problem with leaving a Mini turned on indefinitely. In fact, the server version of the Mini is intended to be left on.

Personally though, I would just let the computer go to sleep when idle. It won't save that much on the electricity bill but the computer might as well be "off" when you're not using it. (And sleep mode is more or less the same as turning it off. Minimal power consumption.)

I don't drink coffee so it will feel like forever! ;)

It goes into sleep mode but I don't physically shut it down. I keep strange hours and like the computer ready at a move of the house. I know, I'm impatient but life is short! :)
 
For going on 25 years, I've kept my desktop Macs connected to surge protectors, and shut them down at night or during periods of non-usage. I also turn the power strips off as well.

I've come to believe that it's "good maintenance" to boot from a cold shutdown. That guarantees that after rebooting you'll be on "a fresh start", fresh login, etc.

Just doing that much can clear up glitches and problems now and then (item in trash that won't empty, etc.).

I will leave my MacBookPro on sleep for a few days at a time, but try to restart that "from scratch" periodically, too.

No, there's no problem leaving them running. I have a Mac mini that serves as my Plex server, as well as other computing duties. It's on 24/7 for several months at a time. Zero problems.
 
I have a Mac Mini 2011 since January 2012, and I turn it off every night. Never had a problem.....

Do you unplug it too? It still draws power unless it's unplugged.

The server is pretty much the same machine as the regular mini - the main difference is software, and that difference is only to add management of multiple users instead of just one.

You can leave most modern computers on all the time and let it sleep with no issues. It's less of a shock to them than booting up once a day.

I've always left my machines on 24/7. When they are not being used they go to sleep. There is no wrong or right answer here. Leave it running or turn it off... pick your personal preference.

I turn it off for only 2 reasons, I go away on vacation or thunderstorms (chance of power outage). In the case of chance of power outage I unplug my tv, computers, and disk drives from power.

I had my time machine drive die when I lost power during Sandy last month. At least it was my oldest drive. The enclosure I had it in was still good.
