Purchased Used MBP & Wiping Clean - A Couple Questions

[Gmas]

So I just got a great deal on a very minimally used 2017 Macbook Pro 15". It seems as though the previous owner wiped it clean before selling to me, but to be safe, I was going to wipe it clean myself and reinstall High Sierra fresh.

I've read a bunch and I think have a handle on the process to do this via the Recovery Partition during startup. Just had a couple questions regarding a few steps...

- I have a 2017 Retina MBP with SSD - should I go with APFS over Mac OS Extended when reformatting the SSD? What I've read seems to recommend that for SSD's.

- My HD is 1TB - is there any need to partition it at all?

- any other best practices or tips when going through this process? Don't want to mess something up or have to do it a second time.

Thanks so much for any pointers!

When you install High Sierra, it converts HFS to APFS for SSDs. You don’t get to choose.

There’s no need to partition.

Actually it is possible to keep HFS+ by following these instructions: https://forums.macrumors.com/thread...ling-macos-high-sierra.2078517/#post-25237187

As for is it beneficial depends on several factors such as potential incompatible software, need to install previous OS etc.

Hard to say without further information from the OP.
