Never had this much trouble trying to do a clean install before!

It seems as though Apple Is trying to make it as difficult as possible so that most users eventually get fed up and just give up and just purchase a new machine.

That seems to be their aim at least and it never seemed to be like this with all the problems so many people seem to have.

Maybe just forget about doing a clean install If everything is working well and just carry on.

Are you actually having problems with your existing system??? Maybe I missed that if you mentioned it.

The problem is I wiped the drive first in disk utility which has been my normal method so I was stuck. If I can't do a clean install again I will restore from the Time Machine backup and just delete everything and rename. Thankfully not a lot on the backup I used, that computer is just used to power my Epson 9900 and really serves one purpose and that is to be a RIP.

I don't think I'm really understanding what you say here, especially when you say "and just delete everything and rename". What is the point of doing that.

A trick used years ago, with HDDs and with things acting goofy or slow, was to use Carbon copy cloner to make a backup clone, wipe and zero-out the original drive, and then use CCC to copy back the clone onto the original clean drive. No need to delete or rename anything and a lot of unnecessary junk gets thrown away in the process and also cleans up a lot of of fragmentation.

Of course a whole different process exists with the newer SSDs. They don't like being zeroed-out and I understand it doesn't improve things anyway.

Personally I find so called mac OS Clean Installs to be a waste of time and don't really improve things a lot unless the OS was completely screwed up. Others have found the same thing. For some reason, other users don't believe us.

I don't know what your reason was for doing a clean install in the first place, but it didn't sound like you had anything really drastically wrong.

I am setting this computer up for my dad who is complete tech illiterate. The iPhone and iPad is a bit of a challenge for him. I am setting this iMac up for him at home and want to make things as simple as possible. With the current install it has stuff that is not needed and wanted him to have a clean install like a fresh new computer.

I do this when giving a computer away to family because again, it is like getting a new computer. They don't need software and things I had on it before nor will it work as they are specific apps for specific devices like wide format printers, or CTP's.

Would OS Reinstall work, and maybe wipe the drive in between to get rid of any surplus stuff???

That is what I was attempting and where I had issues. It kept saying there was something missing that needed to be downloaded but gave no option to download it.

I spent a day trying to get my MacPro 3,1 to go back to Snow Leopard. Apple has become Microsoft in its control-freak approach to allowing legitimate users to install its operating systems.

I could probably upgrade past High Sierra but it's fine as is for what I use it for.

That sounds like a typical answer from Apple that may not and often does not even work, especially when one is trying to install a much earlier OS such as Mavericks.

Getting an earlier, older Mac OS version installed has become a real PITA and for no real reason. And often, unfortunately, their web page tutorials of how to do not always work.

Maybe just give Apple Canada a call and see if there's a decent human tech that can help at the other end.

Apple has lost the balance that they had of form and function. Not sure I would even get a Mac again for home use. I have no issues with Windows 10 and my home use is very light, so next go around I will look elsewhere. Apple has just become to self righteous in how they look at the computing world and their users.
