The idea behind a macOS Clean Install

Thanks for the A2A. The question is too broad to be answered. If I answer it exactly as written, then no, a MacBook battery does not drain faster with Windows installed on its drive. Just installing something will not cause the battery to drain fa.

When you install a new major version of OS X, or after some time has passed, it is a good idea to do a clean install (that is, to erase the disk you are installing OS X onto as part of the installation process).

That will make your Mac run blazingly fast for a few months or more, and many people report that it fixes longstanding problems they’ve had too.

It used to be common practice to occasionally run a clean install, and then manually migrate all the files and settings over in order to get a completely fresh start. However, it has been shown in recent times that in the vast majority of cases if you simply run a clean install, then duplicate your old home folder to your new disk, you will get all of the same advantages as a clean install followed by manual migration, with a small fraction of the effort.

Mac Clean Install Procedure

Here is the clean install procedure which can be performed at least every time a new version of macOS is released:

1. Download the macOS installer from the App Store. You can download macOS Big Sur by clicking here.
2. Backup all the data to an external disk with a clone. Two options are to use Duplicate (a free utility which can copy and paste an entire bootable volume), or Mac Backup Guru (a paid, fully featured backup utility with unique incremental backups capability) for that.
3. Create a bootable USB Installer with Install Disk Creator and boot from it. Erase the startup disk and install macOS onto it. Boot up from this newly created startup disk.
4. Note: The Finder’s built-in “Copy” and “Paste” will not work for the following.
   Go to the backup disk and use Duplicate (free) or Mac Backup Guru to right-click and select Copy on the home folder (eg: External Backup/Users/Bob) and then Paste on the Macintosh HD/Users folder on the startup disk. This migrates all of your personal data and settings to your new home folder.
   Then migrate the applications by selecting Copy on the External Backup/Applications folder on the backup disk then Paste on the startup disk (eg: Macintosh HD). This will copy all of the applications which are present on the backup disk but not present on the startup disk to your new Applications folder, and automatically skip any applications which are already on the startup disk.

Drain Runner Mac Os Update

At this point, after a reboot and some minor adjustments (the Dock may not have your previous configuration for example, if you did this while logged into the same user account as you just updated), your new OS should be indistinguishable from your previous one, while being faster and smaller due to reduced clutter.
