Amazing Mac Uptime: 454 Days

ibook record uptime 454 days

Just when I thought my personal record uptime of 160 days on a MacBook server was exciting, one of our readers blew my uptime away… by almost a year!

Seriously, Stephan Burlot‘s personal record uptime? A staggering 454 days with his iBook. Apparently the iBook monitors his homes electrical usage and runs Mac OS X 10.4.11, and so there is rarely a need to reboot the machine, and it basically never gets turned off. Stable, reliable, trouble free. How awesome is that?

If you didn’t know, uptime is just a measure of how long your computer has been running without a system reboot. A long system uptime is a geeky badge of honor of sorts, and obviously a nice sign of system stability. You can check your Mac uptime by typing ‘uptime’ into the Terminal. I’ve had some pretty impressive uptimes on Macs and Linux machines before, but at the moment this current Mac being typed on is at just 24 days… not bad, but certainly not into the hundreds or over a year! Obviously, stable servers will have longer uptimes than personal machines, so your mileage may vary. Anyway, just kind of fun geeky stuff.

Oh and if you have a whopper uptime, do share it with us in the comments. Or even if it’s not that impressive, it can still be worth sharing.

    Never even heard of the Terminal or any of this. (I’m embarrassingly the least tech-savvy person of my generation. I was born in the 80s and don’t know the first thing about computers, software, hardware, etc.) But I figured out how to find my Terminal, typed in Up Time, and I’m at 81 days on it. Cool thing to know, thanks!

    Running a mid-2014 rMBP with current uptime of 235 days. It’s used daily for web browsing, video consumption, light gaming, running VMs and other various tasks. macOS 10.12 stable af

    Slightly over a year is not that impressive anymore. One of my OpenBSD servers (not OSX/Darwin but at least it’s BSD) was recently found to be up for, as I wrote, “longer than a PI”, 1149 days or 3.14-something years. It stayed up for several months longer, but eventually there was a mighty thunderstorm and the UPS gave out before the power came back on. As others have pointed out, 8 years is not unheard of.

    In the summer of 2007, in order to keep a software demo from expiring, I had a mac mini running for about 7 months, including a week where I was gone on a trip, and had to put it into a locked, safari-only kiosk mode for the housesitter to use. I finally had to shut it down when it came time to change apartments. Seven months isn’t that big a deal, but just this morning I woke up a laptop that had been asleep in my storage room for the last 8 months. It came right back up without any hesitation or hiccups.

  6. Ian says:

    i guess nobody here’s heard of, The Worldwide OSX Computer uptime challenge?

    The absolute uptime record (as far as Hitup’s competitors go, at least):
    Anders Thorssell from Sweden with over 8 Years (3180 days, 11:36). not too shabby. :)

    • Another Ian says:

      Right – that’s basically what I came on here to say. seems to be no more, afaict, but yeah, good ol’ Anders Thorssell was in the lead for a long, long time back in the day…

  7. Brent says:

    I didn’t know anybody kept track of such things. I have no proof but I had my 14 ibook running none stop for over 2 years close to 3.

  8. Ben says:

    My MacBook’s battery gave out 41 days ago and I have had it plugged in since then and guess what? No crashed, no need to reboot- and I use it all the time for hours on end!

  9. Nadia says:

    and i’m happy with 6 days :D

  10. Justin says:

    I have a machine here that has an uptime of 462 days.

  11. Mike says:

    Wow, and I’m excited with two weeks…

  12. Joseph says:

    I can imagine all the dust that builds up on the heat sink over all that time!

    I wonder what the last patch was installed on that mac. :) I like the uptime game too. I manage lots of unix servers and have my own macs but patches take a front seat for me and often a reboots required so I stopped careing. especially since I’ve seen a win 2000 server with only “sp1” on it be up for over for over 4 years at one company I worked at. i turned white haired that day when i found it.
