Apple iMac Data Recovery

iMAC G5:

I have an iMac G5 computer which is preventing me from getting access to some of my documents. These are some old documents which now need, and that have become obsolete on the Mac. The thing is that although I can view them but I cannot open them or copy them because the computer has somehow ‘locked’ them. This means that, although these large documents are taking up a lot of room on my hard drive, I cannot open or copy them. I have looked on the Get Info box, and it says that the system is Locked, and there is a greyed-out lock area which has a large tick in it. I want to be able to uncheck this box so that I can finally copy this data from the drive, but I am not able to do this. I took the iMac to the Apple Repair Store and they said that the files are beyond repair and recommended a data recovery firm to recover the data.

iMAC G5:

I have an iMac G5 which was given to me by a good friend some time ago, and which has now not been used for several years. The main problem is that I have some information on the computer which I want to extract before I throw the iMac away, and at the moment I can’t do that because some of the RAM is missing from the computer. I have only one RAM chip on the motherboard, and because I wanted to start the computer up again to recover the data I need, I put in a second RAM chip. I turned on the machine, but I got a series of beeps which sound like a code message, but I can’t get any further into the system than this. I am not even able to boot it up properly. I really want the computer to work so that I can extract the data, but I know that it will not work with the one RAM chip that was originally in the motherboard.
