pssquirrel:
I'm able to answer part of your questions:
I'm not sure if you can 100% get rid of PRS+ technically spoken. Kartu?
That means:
- If you just want to deactivate PRS+ (leaving some invisible traces somewhere in the hidden part of the memory) it is very simple and runs on a MAC. I've done it several times. No problem. So far I understand the 'thing' PRS+ will be removed 99%. The 1%-part is that part which requires the installer (which doesn't function in your case) to install. It remains on a hidden part on the reader.
- If you want to get rid of PRS+100% technically (including the 1%) I don't know. Reflashing with SONY-software may not work (I tried it and it didn't work out of the box). But, stressing out once more, that should not be necessary because YOU will not recognize it. Maybe SONY will in case of sending for repair. I've done it 2 times with PRS+ installed. No problem in my case. They have done guarantee repair with PRS+ on the reader (and returned the reader without PRS+ ;-)
- hard restore:
No. A hard restore does nothing concerning PRS+
So, in short:
YES, it is very easy with a MAC to remove PRS+ without VISIBLE traces.
