My MBP is a 2016
Model Identifier: MacBookPro13,3; it has a 500 GB drive. I've upgraded the OS from Mojave in the beginning, to Monterey just recently. Everything seems to be working as it should, but my SSD is near the limit (see screenshot below).
I don't understand how I have gotten to nearly 350 GB. Someone suggested that the upgrades, and "general usage" may lead to a lot of cruft in the file system. At any rate, I removed about 80 GB of data earlier today after copying it to another drive. The totals shown below are after removing the files I wanted to keep.
I found a procedure from the macos User Guide named "Erase and reinstall macOS", but at the bottom of that page it has another option for Erase your Mac.
I have several apps I don't need, and Desktop and Documents are "in the cloud". I'd be happy to still have things like my iCloud account, but will gladly forego that if it frees up 30 GB or more.
Which of these two options will result in the most free space on my SSD? Are there other pros & cons to be considered?
