failed attempt at installing leopard

As the person doing the work, I would say its his responsibility to ensure that your machine can run the software he is installing.

If he was aware of this problem and warned you, then its your fault. However, it sounds like he didn't do his research.

 

It sounds like your friends fault. Although, if you knew about this problem and didn't warn him than it's your fault. Then again, you didn't succeed what he payed you to do. I would say it's half his fault, and half your fault.

 

I am a consultant. I would never imagine charging someone if I started something I couldn't finish (not the same but same concept). If someone is charging you, they either do it to completion or they don't get paid. The person that is charging you is claiming expertise and should know all issues and warn you before starting. I wouldn't pay this person one penny. In the future, I would get a guarantee before beginning on how many hours. Also, a guarantee that if your machine isn't faulty they will not charge for own ignorance and problems which should be known before beginning.

This is something the IT expert should have known. I cannot imagine charging a friend $35 to help out with their computer work. Maybe I know my friends better or something, but I have helped out with computer stuff for a day and had my friend buy me dinner instead of payment. I cannot imagine charging friends for help. Any of my friends would help me move, which is the worst thing possible, and not expect more than a six pack and pizza for dinner.

I just don't get this. Then, if I was charging someone, I would never charge them if I made an error and messed something up, or didn't know something I should have, or just plain wasn't capable of doing the work for any reason no fault of the person I was doing the work for. Really this is ridiculous.

 

The BEST way to install Leopard is by making a backup/clone to an external drive and then performing a clean/fresh install and then migrating the old data back on. We charged for the installation of Leopard as problems were fairly common when simply updating to Leopard as they changed so much in the OS from Tiger, and because we did just that: a backup, fresh install and migration.
