Re: [CGUYS] boot G4 or Intel Mac from flash drive?
Techtool Protoge is on a FireWire, not USB drive. http://micromat.com/index.php?option=com_contenttask=viewid=34Itemid=49 That's right. I forgot that detail. Booting from FW has been built into the hardware for many years. Booting from USB is newer, but works for recent models (as previously noted). I would expect USB booting to be less reliable just because I generally find USB to be less reliable, but I have not tried it. I note that Apple's migration tool uses FW, not USB, even though Macs all come with USB2 these days. Haven't seen a tiny FW drive like that before. Can I get one without the TT software? They are rare, but if you google on firewire flash drive you will find them. Reviews say they are no faster than USB2 flash drives and a bit more expensive. Definitely a special-purpose only product. * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?

Re: [CGUYS] [SPAM] Re: [CGUYS] Security Ignorance
You sure about that John? eWeek seems to agree with me. Now, I won't argue that running as a least privilege user will absolutely eliminate security exploits... You misapply the eWeek story. EWeek is comparing different settings of the same insecure OS. No one here is proposing that some settings are less dangerous than others. You don't make a good case for your position by trying to change the topic. The ease with which you can change these settings in Windows is prima facie proof of insecurity. The reason you have to jump through hoops to do this on a Mac is exactly because of the built-in security. Also note that that Apple procedure is not actually changing the name on an account. It is migrating the contents of an account to a new account and then changing security settings of the files that were moved. This does not really get you what you want. The 501 account has special privileges when running as administrator. This new account will not have those. Since you can log in using the long name I don't know why you insist on changing the short name. Why not just make all the long names the same and be happy? This is an artificial crisis. * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?

Re: [CGUYS] UPS Question
The more sophisticated units often have self-test circuitry even if the unit is setup to be monitored by a connected computer; this may relate to the 2-4 AM thing. The other issue might be a failing battery. They do wear out. I have 2 TrippLite 1000VA units that have a real time read-out for the line voltage. They were about $100 the last time I saw one at Costco. YMMV I know UPS issues have been covered in the past. As many of you may know, I'm an advocate of using them. Recently (within the past 2 weeks!) we have begun having UPS issues: To wit: Sometimes, in the middle of the night (2 am - 4 am), two of our UPS's begin to click / beep. Not sound an alarm, mind you, just to click / beep quietly in a rhythmic pattern. I cannot find reference to what this might mean, though I think it means that the circuit being used is browning out power and the UPS is making up the missing power. Last night this happened at about 11 pm!!! Eventually, the UPS's (we have many, but only two are involved in this situation) begin to blare. Then everything shuts down and they continue to blare until reset and recharged. This is a very frustrating situation as it only affects two of our 4 UPS units (all in the same room, but possibly on separate circuits). It is also happening to a neighbor! Same scenario. Only our UPS's are far enough away that they don't wake us. Hers, sadly, wakes her when it begins to scream. (Please don't ask about the 2 am - 4 am thing. I sometimes work late into the night/morning.) We can tell when this scenario has occurred because a telephone answering machine ceases to work, and because my iMac is turned off. There are two UPS units involved. One has only the telephone answering machine plugged into its battery back-up sockets, and the other has only my iMac connected to its battery back-up sockets. Dedicated UPS's if you will. It is unclear if these are on the same circuit breaker or not. It's also weird that sometimes one of the UPS's is affected, and sometimes both of them are affected at the same time. I have searched for references to sounds made by APC UPS units without success. These units are all relatively new (a higher capacity one was purchased last week for my computer in the hope that would help resolve the problem with my computer shutting down, but to no avail), and their batteries should be in good condition. Any help / advice / would be appreciated. -- I may not have gone where I intended to go, but I think I have ended up where I needed to be. - Douglas Adams * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?

[CGUYS] Details on Apple's Time Machine
This is a long article and the first part is a history of backup strategies (something not everyone will find interesting). However, after that it goes into a lot of detail about Time Machine. This is a big deal for Apple and they have invested a lot in making it work by making a very interesting change to how its file system works. They have created a new type of alias (shortcut) that keeps a file around as long as any one of these new pointers exists and lets them stack up multiple instances of the same file. This allows them to make many snapshots of your files while automatically eliminating duplicates. Very interesting. http://www.appleinsider.com/articles/07/10/12/road_to_mac_os_x_leopard_time _machine.html * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?

[CGUYS] UPS Update
My thanks to all the suggestions re. the UPS unit(s) that we have had difficulty with. My husband got serious and did some internet searching re. APC UPS units and found some info about the Battery Back-UPS ES being problematic when dealing with line fluctuation. We phoned APC today (sent them info by e-mail and they actually sent back a phone # that actually reached a real tech support department. Very impressive.) It turns out that they are replacing the unit I bought 3 weeks ago as being defective. They are replacing the unit we bought a couple of years ago (still under warranty) as being defective. They are replacing the battery in a 3rd unit, also under warranty. I'll keep you posted re. whether, or not, the replacements work any better than the current units.
