I opened the pdf, pasted in a digital copy of my signature, emailed it, and was done. Trying to duplicate that today, I am unable to paste the signature graphic into the pdf document. I'm not trying to be a spoil sport here. I'm genuinely interested, but isn't this a rather glaring security problem? Wouldn't the signature stay as a separate layer in the PDF, and hence be 'cut and paste'-able onto any document the recipient wanted? I know a bit of Photoshop can do the same for any document, but doesn't this make it stupidly easy? At least you'd want to set some permissions on the PDF, right? ___ MacOSX-talk mailing list MacOSX-talk@omnigroup.com http://www.omnigroup.com/mailman/listinfo/macosx-talk
help?
I'm trying to find out why eyetv wakeups only work sometimes. Among other things I see lots of Can't create kext cache / - owner not root lines in system log and wonder what they mean. Google has lots of references to lists and discussion groups where people ask about this and some people make guesses. :-( Presumably someone at Apple knows. Is there any forum, list, or newsgroup that Apple people read and on which they give real answers? -- Bill Ehrich ___ MacOSX-talk mailing list MacOSX-talk@omnigroup.com http://www.omnigroup.com/mailman/listinfo/macosx-talk

File Sharing troubleshooting
Seem to see a lot of mention of this trouble on the web, but nothing that felt very edifying: Previously, I have been able to get wireless file sharing enabled between my 2003 Powerbook (with Tiger) and my Air (running Snow Lep). Now, I can't seem to get either to mount the other. I did recently switch to new G station/router (came with Verizon FIOS), BUT I could swear that sharing continued working even after the switch. I can't narrow down a cause, but at any rate... is there a list of steps to go through, to troubleshoot? I have turned the Firewall on/off on both Macs; no diff. ___ MacOSX-talk mailing list MacOSX-talk@omnigroup.com http://www.omnigroup.com/mailman/listinfo/macosx-talk

It depends what you expect out of a signature. If you want to be able to prove that you signed something, or to keep someone from digitally altering a document after you signed it, a personally created key is sufficient. If you want others to be able to prove that you signed something over your non-cooperation, then you have to go the whole trusted-issuer route. If you get only a free key, your digital signature protects your interests strongly, and other people's not much at all -- which, looked at from that perspective, is a refreshing bargain compared to most free stuff. If other people want my signature to protect them, I'll be happy to sit down and have a chat about what it's worth to them. :-) -- Macs R We -- Personal Macintosh Service and Support in the Wickenburg and far Northwest Valley Areas. http://macsrwe.com ___ MacOSX-talk mailing list MacOSX-talk@omnigroup.com http://www.omnigroup.com/mailman/listinfo/macosx-talk
