Time Machine backup negates a clean install?

[Jasonstevens]

I'm on the public beta and have had a lot of finder issues and wanted to just start fresh as I've had this issue through a few betas and am assuming it's just an error from installing new betas on top of each other.

If I restore from time machine once I install a fresh copy will this negate the good of a clean install and just bring back all the same problems? Or does time machine just backup my files and documents and nothing of the system files?

Depends on how you setup Time Machine. If you did not exclude backing up system files then Time Machine will backup those files. When you do a clean install you can selectively manually copy over file from your Time Machine backup. I would not suggest that you do a blanket restore from Time Machine if you are going to do a clean install. Besides that I would not suggest restoring files that you have from a beta release.
