can i delete the data in the system log? it takes up 26 GB of my hard disc! help please!

Thanks for your help Brody. I have onyx in my utilities and I'm trying hat to get the permissions all straight. I think t will help. I' ll let you know how hat goes! Will that not delete the log data correctly or is your suggestion better? Thanks!

Hi Brody.

I am nervous of deleting the log file without using onyx or another programe. I am a novis with computers. I have done all the clean ups in onyx. I still have bad problems. I had a new motherboard about 2 years ago. I give new a snippet of my consul, it looks like everything is going wrong and thats why the cosol messeges take upa so much space. I have tried to delete from the consul but the trash is unavailable/greyed out.?

This is a tiny snippet from today!

Hi Brody,

I just tried your advice. Im not sure that i did this correctly, can I please clarify, is the 'terminal the space where you type? thanks Brody!

Hi Linc, thanks for your advice, I agree , I didn't feel happy about just deleting the log even if I could. I can see the size at the bottom of the log window. I was alerted to the log files taking up all my disc space when I used disc sweeper Programe. I was advised at the apple shop that I could just delete the log files that t's no big deal! And the best way to deal with it is to re enstall my osx. Then my upgrade discs( snow leopard). What do you think?

Ok I'll try that, thanks!

Sorry I've tried that and a window comes up but no general section available. I've been trying to do a screenshot of my log window so you can see at the bottom its big size. It doesn't look like its growing too much, it's now 27.87 GB, but i cant get it on here.

I'm not very keen to put on the osx original discs and wipe the drive, then I'd have to put on snow leopard box set to upgrade, , I'd like to get this fixed in an easier way if poss. thanks again for your help.

Ok thanks very much, I have to go out now so will try it later!
