Determine Total Runtime of Computer

[ender land]

Hi all,

Is there an app which simply keeps track of how many hours your computer has been on for? Something similar to the battery cycle count (except just total time computer is on).

Or maybe this is hidden in the system information somewhere?

iStat Pro will track your total uptime since your last restart.

can determine this in Terminal

terminal command "uptime" will give you this information.
also "last" will list who logged in and for how long.

The techniques described in the two posts above mine are correct; however, you will not get the total number of hours your Mac has been turned since it was made just the total number of hours since it was last started up. Ie., if you reboot it the time will start back at zero.

... you will not get the total number of hours your Mac has been turned since it was made ...

I don't think there's anything that will track that, and that's not what the OP asked for. Plus, "uptime" doesn't distinguish between in use or sleeping; only time since last reboot. I don't know of anything that will get more detailed than that.

I'm not aware of any application that has this capability.

Istat Menus has "Uptime" next to "Actual Running Time", so you get actual time used, and with a bit of maths how long it's been asleep.
BUT, total time your computer has been on ever? It'd be nice, but pretty impossible. Unless istat (or similar) dumped it's current "uptime" values to disk before it shut down (or every xx minutes, in case of some disaster), and then picked up again when it relaunched (presumably at login). Wouldn't be that accurate, or cope with reinstalls, and probably a whole bunch of other problems I haven't thought of that probably explain why it appears no one has bothered to do this yet.
