Catalina fail to install after HDD format resulting in error PPPM003
so my late 2013 iMac was running a little slow in the past few months therefore I decided to format its hard drive and do a clean Catalina OS install. All went fine until the OS installer failed to complete the task and gave an error that it was unable to do so. After a few tries hoping it was some internet flaw it became clear that something was up. So I did a diagnostics test on boot and got no error code at first, which was odd. After a lot of tries and confusions I repeated the diagnostics test, finally showing an error code: PPM003. After looking on AHS code references it showed that was a “failure at integrated memory level”. That got me confused cause that iMac doesn’t have inboard memory as far as I know but anyway. So I brought the computer to an apple service provider so they could swap the memory modules and see if it worked.
The technician that worked on my iMac said that it was the hard drive that showed that it was worn down so that I should swap to an SSD. I said ok since it was something I wanted to do anyway. After that he reran the AHT tests which still showed the PPM003 error plus he said the computer was indeed slow on boot which was odd considering the new SSD. Then he ran the tests with their in-house new memory modules which still showed the error. I told him to do the test testing separate memory modules in case it was only a single one at fault and still showing the same. So now he doesn’t know what to do and neither do i.
So after all that I wanted to ask. Could this be a logic board problem or is apple diagnostics messing up? Sorry for the essay but I really like this computer and want to get it fixed.
Is dit een goede vraag?
